About us
At a Glance
The debug 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 debug screen.
Description
The following table shows the various parts of the debug screen and their functions.
Address
Element
Function
1
Tabs
The tab in the foreground indicates the current mode (Debug for this example). Every mode can be selected using the respective tab.
2
Module zone
Specifies the abbreviated heading of the module.
In the same zone, there are 3 display LEDs giving information on the module's operating mode:
  • RUN indicates the module's operating mode,
  • ERR signals a fault within the module,
  • I/O signals a fault outside the module or an application fault.
3
Channel field
Is used:
  • 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 presymbolize the input/output objects.
    • Fault which shows the device faults (in online mode).
  • To select the channel,
  • To display the Symbol, name of the channel defined by the user (using the variable editor).
4
General parameters field
Specifies the parameters of the channel:
  • Function: specifies the function configured. This heading is frozen.
  • Task: specifies the MAST or FAST or AUX0/3 task configured. This heading is frozen.
Specifies the parameters of the channel:
  • Function: the Global unforcing button provides direct access to the global unforcing of channels function.
  • Task: specifies the MAST or FAST or AUX0/3 task configured. This heading is frozen.
5
Current parameters field
This field displays the state of inputs and outputs and the various current parameters.
For each channel, there are four columns:
  • 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 faulty (indicated by the LED built into the diagnostics access, which turns red).
  • Applied outputs to indicate the output fallback position.
