About us
At a Glance
The maximized debug screen is used to temporarily modify the operation of a project at counting module level, with a view to detecting programming faults. It displays the status of inputs, outputs and main channel bits, contents of registers, and possible faults. It is used to control or force (lock) certain bits.
Illustration
The diagram below shows an example of a maximized debug screen.
Description
The table below shows the different elements of the maximized debug screen and their functions.

1
Tabs
The tab in the foreground indicates the current mode (Debug for this example). Each mode can be selected by means of the corresponding tab. The available modes are:
  • Debug only accessible in on-line mode,
  • Diagnostics (Fault) only accessible in online mode.
  • Adjustment,
  • Configuration.
2
Module zone
Shows the abbreviated name of the module.
There are three indicators in the same field that provide the status of module in online:
  • RUN indicates the operating status of the module,
  • ERR signals an internal error to the module,
  • I/O signals an external error or an application error to the module.
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
Zone general parameters
Allows bits to be unforced and the counting function to be displayed:
  • Unforce: this button allows forced bits to be unforced.
  • Function: calls up the configured counting function. This heading is fixed.
  • Task: specifies the MAST or FAST task configured. This heading is fixed.
5
Display and command field
This field displays the status of inputs, outputs, intermediate bits and the values of the various counting in progress registers. It is also used to control and force various objects (bits).
The field is divided into function groups corresponding to the main functions.
NOTE: the LEDs and commands that are not available appear grayed out.
