Working with Standard Functions

A configuration is shipped with the configuration software “ProTool” or

“ProTool/Lite” that contains standard screens.

Using these standard screens, you can activate all the functions necessary for operation. The description of the individual functions in this manual is based on the standard screens. If you want to work with the standard screens, load the configuration shipped with the software. This configuration is in the directory ProTool\Standard\C7 621.pdb.

If you have not loaded a configuration, the English standard screens are active after turning on the power. These are loaded from the firmware of the C7-OP (see Section 2.1).

Note

The supplied standard screens call special screens that are loaded in the firmware of the C7. You can also call these screens in your own configuration with the “Special screen selection” function.

The standard screens contain functions that are fundamental to the basic operation of C7, such as Display Screens, Modify Password and Set C7 OP Operating Mode. Process-specific implementations, such as event messages or screens for the process, are not included.

Standard screens are called from a basic screen by pressing a softkey. From the basic screen, you branch to the following screens:

S Screens

The screen directory is called to display screens. All the screens which were assigned the “directory” attribute are listed here. If you have still not created any screens of your own, the directory will contain only two standard screens, “Counter” and “Timer” (see Section 8.3).

S System settings

You can modify settings in the online mode. This includes, for example, selecting the C7 mode, changing languages, or setting the date and time.

Overview

Standard Screens

S Status Variable

The PG function STATUS VAR is called; you can use this to display PLC addresses.

S Force Variable

The PG function FORCE VAR is called; you can use it to display and modify PLC addresses.

S Password processing

The superuser assigns the passwords for the different password levels.

The logout function is also included here.

Standard configurations, with ready-to-use standard screens, are supplied for the C7-621 with the ProTool configuration software. Figure 7-4 shows the screen hierarchy for these standard screens. You will find detailed information about the functions and how to use standard screens in the corresponding sections of this manual.

Figure 7-4 Screen hierarchy of the Shipped Standard Screens

If there is no configuration available on the C7-621, for example when you first start up, the English standard screens (Figure 7-5) are loaded from the memory of the C7-621.

Message level

With the ^ENTER key, you change from the message level to the screen level. At the screen level, you can operate and monitor the process or system using the appropriate screens and standard screens and make system settings.

Taking standard screens as an example, the description below explains how to branch from one screen to another within the screen hierarchy.

Step Activity

1. Call the standard basic screen in your configured screen hierarchy.

2. Using the softkeys beneath the symbols « and », you can move the displayed screen segment of the active screen (scroll screen function).

3. You can branch to the next screen by pressing the softkey beneath the screen text. A vertical line designates the assigned softkey

Figure 7-6 Branching at the Screen Level

You select a screen by pressing the softkey assigned to it during configuration.

If either of the symbols ^<< or ^>> is displayed at the beginning or the end of the second line on the display, you can use the screen scroll function for further selections with Fl or F5, if the entry you require is not within the visible display area.

Functions are called by means of the softkeys assigned to them during configuration.

To protect against unauthorized use, a password with a suitable password level must be entered first for some functions (see Section 7.7).

Figure 7-6 illustrates branching to different functions.

7.3.1 Setting C7 OP Modes

You can set the Online, Offline, and Transfer modes on the C7 OP using standard screens.. Table 7-2 explains these modes.

Table 7-2 C7 OP Modes

Mode Explanation

Online In the online mode, there is a logical link between the C7 OP and the C7 CPU, or the C7 attempts to establish a link.

Offline In the offline mode, there is no logical link between the C7 OP and the C7 CPU. The C7 OP does not attempt to establish a link and variables are not updated.

Transfer In the transfer mode, data can be downloaded from your PG or PC to the C7 OP. You cannot operate the C7 OP while the download operation is in progress.

If the standard screen for changing the C7 OP mode is not loaded, you cannot load a configuration. You must then run a memory reset on the C7-OP (see also Section 2.1).

Configuration data are always transferred from the programming device or PC to the C7 OP. Downloading to the destination device is described in the manuals for ProTool or ProTool/Lite. In these manuals, simply substitute C7-621 for OP.
