Chapter

1 Introduction

What This Chapter Contains

This chapter introduces you to the ControlNet Traffic Analyzer tool. The following table describes what this chapter contains and where to find specific information.

Main Structure

of ControlNet

The ControlNet Traffic Analyzertoolis a 32-bit Windows_application

running on top of a 32-bit ControlNet Driver. This application is used to examine, store, and analyze network data on a ControlNet network. You can view the behavior of frames on the network, test ControlNet reliability, and make sure that every transmission on the network is correct.

Information Exchange on a ControlNet Network Link

A ControlNet network link’s most important function is to transport time-critical control information (i.e., I/O status and control

interlocking). Other information (i.e., non time-critical messages such as program uploads and downloads) is also transported, but does not interfere with time-critical messages because of ControlNet’s unique time-slice algorithm.

On a ControlNet network link, information is transferred between nodes by establishing connections. Each message sent by a producer contains a Connection ID (CID). Nodes that have been configured to recognize the CID consume the message, therefore becoming a consumer.

1-2 Introduction

See the ControlNet International Specification for more information about information exchange on a ControlNet network link. The ControlNet International Specification can be purchased from ControlNet International.

The following illustration describes the ControlNet network’s link layer services.

ControlNet Messages

The repetitive time interval in which data can be sent on a link is called the Network Update Time (NUT). The NUT is divided into three parts containing three defined types of Media Access Control (MAC) frames:

•Scheduled

Every scheduled node in sequential order is guaranteed one opportunity to transmit. Information that is time-critical is sent during the scheduled part of the interval. The bandwidth is reserved in advance to support real time data transfers. Real time data transfers include:

•real time control data (I/O updates)

•analog data

•peer to peer interlocking

•Unscheduled

All nodes transmit on a rotating basis in sequential order. This rotation repeats until the time allocated for the unscheduled portion is used up.

Scheduled Service Unscheduled Service Network Maintenance Service the “Guardband” 41561 0 ... SMAX 0 ... SMAX Time

Link Layer Services

(13)

Introduction 1-3

The amount of time available for the unscheduled portion is determined by the traffic load of the scheduled portion. ControlNet guarantees at least one node will have the opportunity to transmit unscheduled data every interval. The starting node for each NUT rotates to guarantee each node will have an unscheduled transmit time. The remaining bandwidth supports non time-critical data transfers. Non time-critical data transfers include:

•connection establishment

•peer to peer messaging

•programming (uploads and downloads)

•Moderator

The node with the lowest MAC ID (node address) assumes the moderator role. The moderator frame is transmitted to keep the other nodes synchronized. This moderator frame is sent in the guardband.

ControlNet MAC Frame Structure

All transfers use the MAC frame format shown in the following illustration.

Each node can send only one MAC Frame at each opportunity to transmit. Each MAC Frame contains one or more LPackets

(Link-Packets). Each LPacket contains one piece of “application information”.

Audience

This interface software is written for network specialists. It will assist network engineers in designing and debugging of ControlNet

products and will help maintenance personnel during installation or troubleshooting of a ControlNet network.

Software Package

The software package is a Windows based product so as to maintain consistency across all ControlNet software products and to provide a user-friendly human interface. It is composed of a CD-ROM

installation disk plus the reference manual.

Hardware

8. Follow the on-screen instructions to install the driver and the Traffic Analyzer.

You need to have a ControlNet 1784-PCC PC card or a CN-1000 ISA card installed to work on line. If you do not have a card, ask your local Rockwell Automation representative for a 1784-PCC card package at:

•Telephone: 1.440.646.5800

or contact Pyramid Solutions for a CN-1000 card at:

•Web: www.pyrasol.com/Expertise_DataCom_Support.htm The ControlNet Traffic Analyzer has to be the single client of the ControlNet card. You can use the ControlNet 1784-PCC PC card or the CN-1000 ISA card for applications other than the Traffic Analyzer, but you cannot run these applications simultaneously with the same card. If you use another application with the card, you must go in offline mode or close the Traffic Analyzer tool. For more information about the online/offline modes, see page 7-3.

IMPORTANT Some screen savers take all the CPU resources. When the

Traffic Analyzer tool is in data recording mode, it may lose some data. You must choose the “blank screen” or “none” option in the display properties of the Screen Saver.

(18)

Terminology

Use the following table to become familiar with some terms specific to the Traffic Analyzer tool.

IMPORTANT You may need to disable Power Management if data captures

are missing data.

IMPORTANT The ControlNet Traffic Analyzer and RSLinx cannot run

simultaneously via the same network interface card.

Term Refers to

CNA10 the ControlNet ASIC containing the Media Access Control interface circuitry used to send and receive data on a ControlNet network. Connection ID (CID) an identifier assigned to a transmission that is associated with a

particular connection between producers and consumers that identifies a specific piece of application information.

Filter a selection used to let frames that meet a specified condition to pass from the network to the buffer, or from the buffer to the display. For example, you may set up an input filter that will only allow frames with a source MAC ID of 10 to pass from the network to the collection buffer. Fixed Tag a two byte tag that identifies a specific service to be performed by the

node identified in the second byte of the fixed tag. The second byte of the fixed tag contains the MAC ID of the destination node.

Generic Tag a three byte tag that identifies a specific piece of application information (same as Connection ID).

LPacket link packet - data packaged and labeled by a node in preparation for transmission. LPackets contain a header and data.

MAC Frame a collection of MAC symbols transmitted on the medium that contains a preamble, start delimiter, source MAC ID, LPackets, CRC, and end delimiter. After the ASIC processing, a MAC frame contains time, status, type, source MAC ID and LPackets.

MAC Symbol symbols that represent the data bits to be encoded and transmitted by the Physical Layer.

Trigger a collection that causes data collection to start or stop. You specify the condition the same way that a filter is specified.

Trigger Point a point within the collection buffer where a trigger occurs. If the trigger point is at the start of the buffer, data collection will begin when a trigger condition is detected. If the trigger point is at the end of the buffer, data collection will stop when a trigger condition is detected. Unconnected

Message Manager (UCMM)

the component within a node that transmits and receives unconnected explicit messages and sends them directly to the Message Router object.

4 Triggers and Filters

What This Chapter Contains

The following table describes what this chapter contains and where to find specific information.

Triggers

A trigger is used to initiate a process or to act as a reaction. There are two types of triggers: start and stop. A start trigger initiates the process; a stop trigger stops the process.

Start Trigger View

You see the Start Trigger view when you click the Start Trigger

icon in the Control Panel or from the Actions menu, click on

Control Panel>Define Start Trigger.

A trigger is a prerequisite condition, a passage toward the pre-filter phase. Once you start a trigger condition, there is nothing else to do. There are two types of trigger conditions: one related to the contents of the frames and the other related to the time elapsed. You can combine the two types of conditions. Triggering will start provided at least one condition is met.

The Start Trigger view is shown below.

triggers 4-1

filters 4-8

Start without conditions. Start with conditions. Define how much time is needed to start the analysis.

Enable/disable trigger condition.

(36)

4-2 Triggers and Filters

You can initiate only one specific Start Trigger: a Start Trigger on Data. See page 4-4 for more information.

The following illustration shows start trigger conditions with a Start Trigger on Data added.

Stop Trigger View

You see the Stop Trigger view when you click the Stop Trigger icon in the Control Panel or from the Actions menu, click on Control

Panel>Define Stop Trigger. There are two types of trigger conditions: one related to the contents of the frames and the other related to the time elapsed. You can combine the two types of conditions.

Triggering will stop provided at least one condition is met.

You can check the Center Trigger in Ring Buffer box to add data following the first Stop on Conditions and keep the preceding data as well. Otherwise, when the box is not checked, the data in the buffer is the data preceding the Stop Trigger.

The Stop Trigger view is shown below.

Start Trigger on Data.

Stop without conditions. _{Stop with conditions.}

Define how much time is needed to stop the analysis after a Start.

Stop the trigger in the center of the Ring buffer, keeping data preceding and adding data following the given condition.

Enable/disable trigger condition.

Triggers and Filters 4-3

How to Configure a Trigger

When you choose to start or stop a trigger on a condition, a trigger list area appears. You can add, edit, or delete conditions in this list area by clicking the right mouse button. A pop-up menu appears.

When you add or edit a trigger condition, you see the following box:

TIP

Another way you can add, edit, or delete a trigger condition is by pressing the Insert, Enter, or Delete key, respectively.

Define the Producer MAC ID(s) you want to trigger. You can define: • a single Producer MAC ID (in a range 0-255).

• a group of IDs. Separate the range by a hyphen (2-88). The range can extended from 0 to 255. • multiple IDs. Separate the IDs by a semi-colon (2;9;27) a group and multiple IDs (2-7;3;8). If you do not enter a value in this field, the full range (0-255) becomes the default value.

Define the Producer MAC ID(s) you want to trigger in each LPacket. • For a Generic LPacket, it is the Producer/Consumer ID. • For a Fixed LPacket, it is the Destination ID.

• For a Broadcast ID, it is 255. You can define:

• a single Producer/Consumer MAC ID (in a range 0-255). • a group of IDs. Separate the range by a hyphen (2-88).

The range can extended from 0 to 255.

• multiple IDs. Separate the IDs by a semi-colon (2;9;27). • a group and multiple IDs (2-7;3;8).

(38)

Status of Frames

A frame status can be defined in three ways:

•Good: a frame correctly received by the Traffic Analyzer tool.

•Bad: the Traffic Analyzer tool has detected a problem with this frame (e.g. a CRC problem).

•Null: a frame without any data.

Type of Frame

A frame type can also be defined in three ways:

•Scheduled

•Unscheduled

•Moderator

See page 1-2 for a definition of frame types.

How to Configure a Start Trigger on Data

When you want to add trigger onto data, you add a Start Trigger on Data condition. This implies that you are looking for a specific element and that you know its source, the type of frame, and its destination.

At the LPacket level, the standard trigger only checks for the Producer/Consumer MAC ID in a Generic LPacket or for the

Destination MAC ID in a Fixed LPacket. Within these limits, you can create an unlimited list of trigger conditions that will not affect the processing time during the record.

If you want to start after a specific LPacket - for example if there is a sign of future network troubles - you can create a unique and elaborate trigger condition on an LPacket.

TIP

For a definition of Status, see below. For a definition of Type, see page 1-2.

(39)

Each byte in the LPacket Header can be checked; a sequence of a maximum of 8 bytes will appear in the LPacket data field.

When you choose to start a trigger on a condition, a trigger list area appears. You can add, edit, or delete a Start Trigger on Data condition in this list area by clicking the right mouse button. A pop-up menu appears. Only one Start Trigger on Data can be created at one time. Once a Start Trigger on Data has been added, it can be edited or deleted. Also, you can create a Start Trigger on Data only on Good Scheduled or Good Unscheduled frames.

If you choose to add or edit a Start Trigger on Data, the Trigger on data dialog box appears. You must enter a value in the Producer MAC ID and/or Consumer MAC ID, and link data (if an offset is defined) field(s). Three examples follow showing the different options you can choose in this dialog box.

(40)

Example 1: Fixed LPacket

When you want to add a Start Trigger on Data with a fixed Tag, you see the following dialog box.

Enter the Producer MAC ID you want to trigger.

Define the frame type.

Choose the type of LPacket you want to trigger.

Enter the size of the LPacket you want to trigger (enter in hexadecimal).

Enter the control bits of the LPacket you want to trigger (enter in hexadecimal). The fields reflect the value entered in the Control Bits

field above. See “Interpreting Control Bits,” page 4-16. Enter the LPacket Link Data Offset in hexadecimal. The LPacket Link Data Offset 0 starts after the LPacket Header.

Enter the Link Data you want to check. Enter in

hexadecimal, limited to eight characters.

When Fixed Tag is chosen, enter the Service byte in hexadecimal.

Enter the destination MAC ID you want to trigger.

Select a predefined UCMM service. This value will automatically set the Offset and Link Data. Use this as a quick way to find a service without entering it. This option is disabled if Generic Tag is selected.

(41)

Example 2: Generic LPacket

When you choose Generic Tag, two new fields appear to define the Connection ID. They replace the Service and Consumer MAC ID

fields.

Set the Connection ID Number in hexadecimal. Define the Producer/Consumer

MAC ID you want to trigger.

The Predefined UCMM Service is disable when Generic Tag is chosen.

(42)

Example 3: Fixed LPacket Using the UCMM Service List

When you want to use a predefined UCMM Service, you see the following dialog box.

Filters

Filtering refers to a selection used to allow frames that meet a specified condition to pass from the network to the buffer, or from the buffer to the display. For example, you may set up an input filter that will only let frames with a source MAC ID of 10 to pass from the network to the collection buffer. There are two filtering levels:

•Pre-filter: determine which frames you will put into the buffer. This is a sorting procedure used mainly for adding filters on the destination of a frame.

•Post-filter: determine which frames are going to be in the buffer, i.e., which ones you want to see on the screen. This is the second level of sorting, more precise and elaborate than the pre-filter sort.

The UCMM Service number is 0x83.

The LPacket Data Offset and Link Data values are forced to match the selected UCMM Service.

(43)

Pre-Filter View

You see this view when you have selected the Pre-Filter icon in the Control Panel.

The Pre-filter view is shown below.

Disable Time Stamp

ASIC provides time indication for each frame. If the network traffic conditions are extremely heavy and/or the data capture is missing traffic, then you may need to lighten the task of the ASIC. You can do this by disabling the Time Stamp. See Chapter 8, “Troubleshooting.”

How to Configure a Pre-Filter

When you choose to filter on conditions, a filter condition list area appears. You can add, edit, or delete a pre-filter condition in this list area by clicking the right mouse button. A pop-up menu appears.

TIP You can also access the Pre-Filter view from the Actions

menu: Control Panel>Define Pre-Filter.

TIP Another way you can add, edit, or delete a filter condition is by

pressing the Insert, Enter, or Delete key, respectively.

Click on this radio button to get all frames from the network except the null.

Check this box to Disable the time stamping (the time will not be included in the data capture).

Enable/disable filter condition.

Pre-Filter condition.

Click on this radio button to filter on conditions.

(44)

When you add or edit a pre-filter, you see the following dialog box:

TIP For a definition of Status, see page 4-4.

For a definition of Type, see page 1-2.

Define the Producer MAC ID(s) you want to filter. You can define: • a single Producer MAC ID (in a range 0-255).

• a group of IDs. Separate the range by a hyphen (2-88). The range can extended from 0 to 255.

If you do not enter a value in this field, the full range (0-255) becomes the default value.

Define the Producer MAC ID(s) you want to filter in each LPacket. • For a Generic LPacket, it is the Producer/Consumer ID. • For a Fixed LPacket, it is the Destination ID.

• For a Broadcast ID, it is 255. You can define:

• a single Producer/Consumer MAC ID (in a range 0-255). • a group of IDs. Separate the range by a hypen (2-88).

(45)

Post-Filter View

You see this view when you have selected the Post-Filter icon in the Control Panel.

How to Configure a Post-Filter

Defining a post-filter is a little bit more complex than defining a pre-filter. Post-filtering provides a more precise way of filtering. When you choose to post-filter on conditions, two filter condition list areas appear. These two lists have been designed to show all the

information needed by the post-filter.

•the first list looks like the Pre-Filter list and performs almost the same function; it will be referred to as the top list.

•the second list is used to filter on some LPacket data and will be referred to as the bottom list.

TIP You can also access the Post-Filter view from the Actions

menu: Control Panel>Define Pre-Filter.

Click on this radio button to get all stored frames from the Data Buffer.

Click this button to enable any changes in post-filtering. This will update the MAC Frame Data view.

First Post-Filter condition. The “Yes” means LPacket filter is enabled. Enable/disable

filter condition.

Second Post-Filter condition. LPacket filter is enabled. Click on this radio

button to filter on conditions.

(46)

You can add, edit, or delete a post-filter condition in these two list areas by clicking the right mouse button. A pop-up menu appears.

When you add or edit a post-filter in the top list, you see the following dialog box:

TIP Another way you can add, edit, or delete a post-filter condition

is by pressing the Insert, Enter, or Delete key, respectively.

Define the Producer MAC ID(s) you want to filter. You can define: • a single Producer MAC ID (in a range 0-255).

• a group of IDs. Separate the range by a hyphen (2-88). The range can extended from 0 to 255.

If you do not enter a value in this field, the full range (0-255) becomes the default value.

Enable filter on an LPacket. This enables the bottom post-filter list. You will see a “Yes” in the Filter LPacket column in the Filter/Trigger view.

Disable filter on an LPacket. This disables the bottom post-filter list. You will see a “No” in the Filter LPacket column in the Filter/Trigger view.

TIP For a definition of Status, see page 4-4.

(47)

When you enable LPacket filtering and you want to add or edit frame conditions in the bottom list, you see the following dialog box:

•Size

•Ctrl Bits

•Prod/Cons MAC ID

•Link Data and an Offset

Enter the size of the LPacket header (in hexadecimal).

Define the Producer/Consumer MAC ID(s) you want to filter in each LPacket. • for a Generic LPacket, it is the Producer/Consumer ID.

• for a Fixed LPacket, it is the Destination ID. • for a Broadcast ID, it is 255.

You can define:

• a single Producer/Consumer MAC ID (in a range 0-255). • a group of IDs. Separate the range by a hypen (2-88).

• If you do not enter a value in this field, the full range (0-255) becomes the default value. When Any Tag is selected, you

cannot base your selection on Tag values.

Enter the control bits of the LPacket header (in hexadecimal). The fields reflect the value entered in the Control Bits

field above. See “Interpreting Control Bits,” page 4-16.

Enter the LPacket Link Data Offset (in hexadecimal).

Enter the LPacket Link Data you want to check (in hexadecimal).

IMPORTANT In the preceding example, all the fields have been filled in for

illustration purposes but not all of them are required fields. When Any Tag is checked, only one of the following fields must be filled in:

(48)

When you choose the Fixed Tag option, the Service field appears and you see the following dialog box:

If you don’t enter a value in the Ctrl Bits field, “Fixed” appears in the Control Bits column in the bottom list area of Post-Filter view. If the Ctrl Bitsfield is filled in, the interface checks the consistency with the Fixed Tag option; in the Post-Filter view,

Control Bits field, a hexadecimal value will replace the “Fixed” string. See “Interpreting Control Bits,” page 4-16.

When Fixed Tag is chosen, the Service field appears.

The UCMM Service number is forced at 0x83 when a predefined UCMM Service is selected.

The values in the Offset and Link Data fields are forced when a predefined UCMM Service is selected.

Select a predefined UCMM Service.

IMPORTANT When Fixed Tag is chosen, it is not necessary to fill any fields

because the Fixed Tag option is automatically entered on several bits in the Control Bits field (see the Acc. Always, Tag Pad, and Fixed Screen fields above).

(49)

When you choose the Generic Tag option, the Connection field appears and you see the following dialog box:

If you don’t enter a value in the Ctrl Bits field, “Generic” appears in the Control Bits column in the bottom list area of Post-Filter view. If the Ctrl Bits field is filled in, the interface checks the consistency with the Generic Tag option; in the Post-Filter view,

Control Bits field, a hexadecimal value will replace the “Generic” string. See “Interpreting Control Bits,” on the next page.

IMPORTANT When Generic Tag is chosen, it is not necessary to fill any

fields because the Generic Tag option is automatically entered on several bits in the Control Bits field.

When Generic Tag is chosen, the Connection Number field appears.

Enter the Connection Number in hexadecimal.

(50)

Interpreting Control Bits

The bits of the control field are numbered 0 through 7 and are described below.

Bit 0 - Fixed Tag (type of LPacket)

Bit 0 is the least significant bit of the control field. Bit 0 indicates the type of LPacket. When set (bit 0 = 1), the LPacket is a fixed tag LPacket. Conversely, when clear (bit 0 = 0), the LPacket is a generic tag LPacket.

Bit 1 - Tag Pad (Odd Tag Size)

Bit 1 of the control field indicates whether the tag field contains an even or odd number of bytes. When clear (bit 1 = 0), it indicates that the tag contains an even number of bytes. When set (bit 1 = 1), it indicates that the tag contains an odd number of bytes. A fixed LPacket has an even tag so bit 1 = 0 and a generic LPacket has an odd tag so bit 1 = 1.

Bit 2 - Data Pad (Odd Link Data Size)

Bit 2 of the control field indicates whether the link data contains an even or odd number of bytes. When clear (bit 2 = 0), it indicates that the link data contains an even number of bytes. When set (bit 2 = 1), it indicates that the link data contains an odd number of bytes.

Bit 3 - Reserved

Bit 3 of the control field is reserved.

Bit 4 - Generic Tag (Type of LPacket)

Bit 4 of the control field is the inverse of bit 0 (see bit 0 above). If bit 0 is clear, then bit 4 will be set. If bit 0 is set, then bit 4 will be clear.

Bit 5, 6, 7 - Reserved 7:5

Display Information 5-3

MAC Frames

MAC Frame data is displayed in hexadecimal, plain information with no separation between each other. The MAC Frame data format is shown below.

Between two LPackets, the CNA10 ASIC adds two bytes, which are shown only in the hexadecimal display. Use the following table of CNA10 ASIC tag index and description to interpret these two bytes.

Please note that bad MAC Frames are always displayed in the MAC Frame format. An example is shown below with the LPacket tag index underlined.

LPackets

Data is displayed in hexadecimal but the different LPackets are separated from one another. A small arrow on the left side of the text indicates a new LPacket is starting. The LPacket data format is shown below.

CNA10 Tag Index Description

sm, 0xF8 LPacket from the NAP port sm, 0xF9 Scheduled LPacket from the wire sm, 0xFA Unscheduled LPacket from the wire sm, 0xFB Moderator LPacket from the wire Note: sm = Source MAC ID

(54)

Interpreted

Each LPacket Header is interpreted. The first two lines of each LPacket details the contents of the LPacket Header. The Interpreted data format is shown below.

The next two sections describe LPacket Header information for fixed and generic tags.

LPacket Header for a Fixed Tag:

The LPacket Header for a fixed tag is composed of: Size + Control bits + Service + Destination MAC ID.

See the following table for fixed tag service numbers and their description.

Other Options

Three other options appear in the Data Format section of the Display View Options dialog box:

•Show ASCII - if you check this box, the ASCII column displays

•Short Display - if you check this box, the Status and Type

columns take on an abbreviated form (only the initials of each status and type display)

•Show Frame # - if you check this box, the Frame # column displays

Tools to Manage Frames

The Traffic Analyzer tool contains several functions to help you manage the documents you create.

Bookmarks

If you want to mark some data lines, you can set bookmarks on them. Bookmarks are used to easily jump from one marked line to another.

The Traffic Analyzer tool provides the following Bookmark options:

• Add/Remove bookmarks

• Go to the Next bookmark

• Go to the Previous bookmark

• Delete all bookmarks

Access these bookmark options from the Edit menu, the MAC Frame Data view pop-up menu, or use the corresponding Hot keys. See “Edit Menu,” page 3-3, for more information.

When you add a bookmark on a line, a small flag ( ) displays in the left margin. Once you have added two or more bookmarks, you can use the Go to Next or Go to Previous bookmark options to jump from one bookmark to another.

The current bookmark looks like this: . When you want to jump to the next or the previous bookmark, you always do it from the current bookmark. Use the Delete All bookmark option to delete all the bookmarks.

(57)

Find Data

The Traffic Analyzer tool provides two find options: simple find and advanced find.

Simple Find

Use the simple find function to search for ASCII or Hexadecimal data within MAC Frame Data view. Access Simple Find from the Edit menu. You see this dialog box:

The Find function will rest on the first byte found in the data column of each MAC Frame, in however data format it is displayed.

Advanced Find

Use the advance find function to search directly for coded information in a MAC Frame. Access the Advanced Find function from the Edit

(58)

When you access Advanced Find, you see the following dialog box:

Enter the type of information you want to search for (Producer MAC ID, Frame Status/Type, Prod/Cons MAC ID, etc.) then click OK and the search will start. If the information is found, the corresponding line comes in view highlighted for easy recognition.

Select a Range of Frames

Use this function to select a range of frames for display. Access the

Select Range of Frames dialog box from the MAC Frame Data view pop-up menu.

The top part of this dialog box is similar to the Edit Filter dialog box in Post-Filter. See page 4-12 for more information.

The bottom part of this dialog box is similar to the Edit LPacket dialog box in post-filter. Note the three different LPacket Header tags. Each tag has a slightly different dialog box. See pages 4-13 through 4-15 for more information.

Click this box to show or hide the bottom part of this dialog box.

(59)

You see this dialog box:

Enter the first frame in the range in the Min frame number box and the last frame in the range in the Max frame number box and click OK. By default, the range of frames displayed correspond to the minimum & maximum frame numbers contained in the current document. You can only reduce the range.

Compute Time Difference

Use this function to compute the time difference between two ControlNet frames. Access the Compute Time Difference dialog box from the MAC Frame Data view pop-up menu.

You see this dialog box:

Enter Time T1 and Time T2 values by clicking on a frame in MAC Frame Data view and dragging and dropping it into the Time T1 or

Time T2 box.

Click on the pin to activate the dialog box. When pinned, the box is always visible.

The frame number of the frame is used to easily retrieve the corresponding frame.

The Compare Time result window always shows the positive time difference between T1 and T2.

(60)

After you drop a frame in either the T1 or T2 box, you see a marker next to the corresponding frame in MAC Frame Data view. The markers are shown below.

Next to the frame you dropped in the T1 box you see this marker

Next to the frame you dropped in the T2 box you see this marker

These markers serve as an easy way to retrieve a frame that is used as a time comparison value.

To hide this window, click on the pin button so it is in the “not pin” state. Then click in another window or just click on the X button.

Copy Data to the Clipboard

You can copy some frame data in text format and use it as

documentation. Select some lines from MAC Frame Data view and choose Copy Data to Clipboard from the MAC Frame Data view

pop-up menu or use the CTRL+C shortcut. To retrieve the data, open a word processing application and use the paste function.

You can select more than one line at a time. To select lines in a sequence:

1. Click on a line.

2. Hold the Shift key down.

3. Click on the last line in the range.

To select non-sequential lines hold the Ctrl key down while you click on the lines you want to select.

The data format will correspond to the one that is displayed in MAC Frame Data view.
