QUICKDESIGNER Advanced supports the downloading of application files over the Allen-Bradley Data Highway +, using the PLC-5 Remote I/O Pass-Through feature. The QuickPanel (QP2) is connected as a remote I/O device to the PLC-5. This feature allows the customer to download application files to the QuickPanel without changing cabling, and without having to go from
QuickPanel to QuickPanel with a personal computer for direct downloading. The current Pass-Through release of QUICKDESIGNER Advanced requires the use of an S-S technologies Data Highway + card in the personal computer.

DH+ REMOTE I/O
AB Data Highway plus (DH+) is the means by which Programmable Logic Controllers and
Programming Stations are linked together so that program and status information can be shared among stations on the network.
AB Remote I/O (RIO) is a PLC network that allows control of external racks of I/O via a 2 wire mechanism.
A Rack is a physical and virtual location on the RIO network that contains up to 16 slots. (8 groups, 2 slots/group)
A Slot is both a physical and virtual card location in the Rack that typically holds inputs and outputs, and can hold function modules such as Basic modules. These function modules can contain program data which it gets from the PLC via the Block Transfer mechanism.
Block Transfer is a mechanism by which a PLC can transfer 64 words (128 bytes) of information in one packet to a single slot location via the RIO network.
The Quick Panel can emulate a full set of racks on the AB RIO network. Utilizing Quick Designer configuration software, a Quick Panel can be configured to emulate inputs and outputs ( relay closures and sensor inputs ) and function module I/O (analog values) and the block transfers associated with them.
The standard download feature uses a serial protocol to send application files directly from a PC to a single Quick Panel. The Pass Through mode is an enhancement to the download operation, which allows files to be sent to a Quick Panel that is already part of an active RIO network application. The user selects a PLC location along with a card and slot information. The application file is sent to the PLC on the Data Highway Plus network. The PLC then uses Block Transfers to send the file out to the rack and slot location on the RIO network.
Pass Through Setup
Go to the Project Setup dialog box and select AB Remote I/O as the PLC. Click the Protocol button to display the AB Remote I/O configuration dialog box. Select the PLC type and the Baud rate of the network.
Each Quick Panel on the RIO can emulate one or more quarter racks. For Pass Through to work properly, each Quick Panel must be assigned to its own full quarter rack. No other Quick Panel can share emulation of a rack.
Select an unused rack and select a quarter rack for emulation by clicking the Observe button. Select a BTW and a BTR for a single slot location and assign both to a length of 64. The slot is now setup for a Block Transfer operation, which can be assigned to Pass Through.
Make sure the PLC does not use any BTW or BTR for the selected slot.
In the following example, Rack 2 has been selected. The second quarter rack, consisting of Group 2 and Group 3, has been selected for emulation. Slot 0 has been configured for a BTR of 64 and a BTW of 64.
Click the Pass-through button to display the Pass Through dialog box.
Download Method
Select Serial download to use the standard method of connecting a PC directly to a Quick Panel using an HMI-CAB-C49 cable. Select Pass-Through to download the application file through the Data Highway Plus and Remote I/O network. If you select Ask, the download operation will stop and ask you to select Serial or Pass-Through.
The first time you create a pass through application, it must be downloaded to the QuickPanel using serial download. Subsequent downloads can then be done using pass through.
DH+ Card Name
Name of the card type used for access to the Data Highway Plus. The following name is the default name found in the PT.INI setup file.
SD2 (Sutherland and Shultz)
The PT.INI file contains the Sutherland and Shultz DH+ card setup information. See the PT.INI section for more information.
Destination DH+ Node
This is the node address of the destination PLC.
Note: The node address of the DH+ card in the PC is set to the default address of 61. This address is set in the PT.INI file.
Block Transfer Address
This must be the same address selected as the quarter rack emulation. In the previous example, Rack 2, Group 2, Slot 0 was selected as the slot to use for the Block Transfer operations. Therefore:
Rack = 2 Group = 2 Slot = 0
At this point, Pass Through is assigned to a BTW/BTR. Click Ok to accept the settings and close the dialog box. Click OK in the AB Remote I/O dialog box to complete the setup.
PT.INI File
This file contains setup information for the Sutherland and Shultz DH+ card. The default settings are shown in the following listing. To change the node address of the SD2 card, you must edit the PT.INI file. A download operation will read the file for DH+ card setup information.
Note: If you are running QD3 and other PLC programming software on the same system, make sure only one program is running at a time. If other PLC programming software uses the DH+ card assigned to QD3, then the PT.INI file should be modified to match the settings for the other software. This will allow the card to always appear the same way on the network.
[SD2] (DH+ Card Name)
;SourceNode, this is an octal #, DH+ node # of the SD2 card.
SourceNode=61
;BoardAddress, this is a hexadecimal #, address segment of the SD2 card.
BoardAddress=C800 (see CONFIG.SYS section to configure this address)
;IOport, this is a hexadecimal #, IO port required by the SD2 card.
IOport=250
;TeminalName is any string, the DH+ name assigned to the SD2 terminal.
TeminalName=TCPpt
CONFIG.SYS
The Sutherland and Shultz DH+ card requires an address segment from C800 to CFFF. This is handled by a command line in the CONFIG.SYS file. For example:
DEVICE=C:\EMM386 X=D000-D7FF
If you are running Windows 95, you can reserve resources by opening the Control
Panel\System\Device Manager\Properties\Reserve Resources. Click the Memory button. Add C8000-CFFFF to Settings.
DOWNLOAD
Before the Pass Through operation will work with a unit on the Remote I/O network, a new executable file, and an application file containing the Pass Through Remote I/O setup information must be downloaded to the QuickPanel using the standard serial download. All subsequent downloads can then use the pass through feature on the Remote I/O network.
To change the Rack/Group/Slot assignment for pass through, a new application file must be downloaded to the display using serial download.
To upgrade or reload the device executable, you must use serial download.
Critical faults during a download may require a new device executable file and application file be loaded into the display using serial download.

CAUTION
Do NOT use this protocol with QP1 devices. It is designed to be used with ONLY QP2 devices. For example, QPJ-2D100-L2P is a QP2 device.Tag Variable Table
