At a Glance

The debugging screen shows, in real time, the value and state of each channel of the selected module. It also allows access to the channel commands (forcing of the input or output value, reactivation of outputs, etc.).

Illustration

The figure below shows a sample debugging screen.

Description

The following table shows the various parts of the debugging screen and their functions.

Number

1

Tabs

The tab in the foreground indicates the mode in progress (Debug in this example). Every mode can be selected using the respective tab.

  • Debug which can be accessed only in online mode

Contains the abbreviated title of the module.

In the same area there are 3 LEDs which indicate the module’s operating mode:

  • RUN indicates the operating status of the module

  • ERR indicates an internal event in the module

  • I/O indicates an event from outside the module or an application issue

3

Channel area

Allows you:

  • by clicking on the reference number, to display the tabs:

    • Description which gives the characteristics of the device

    • I/O Objects, which is used to pre-symbolize the input/output objects

    • Fault which shows the device status (in on-line mode)

  • to select a channel

  • to display the Symbol, name of the channel defined by the user (using the variable editor)

4

General parameters area

Specifies the parameters of the channel:

  • Function: specifies the function configured. This heading is frozen. The Global unforcing button provides direct access to the global unforcing of channels function.

  • Task: specifies the MAST or FAST task configured. This heading is frozen.

5

Parameters in progress field

This field displays the state of inputs and outputs and the various current parameters.

For each channel, four items of information are available:

  • Symbol displays the symbol associated with the channel when it has been defined by the user (using the variable editor)

  • Value displays the state of each channel of the module

  • Error provides direct access to channel by channel diagnostics when these are inoperable (indicated by the LED built into the diagnostics access, which turns red)
