The debug screens have a common part as seen below:
Module Field
This table describes the module zone:
LED
State
Indication
RUN
Lit
Module in operation
ERR
Lit
Blinking
Module inoperative
Communication fault
I/O
Lit
External hardware fault (e.g. encoder, variable speed controller, outputs)
DIAG
Lit
Faulty module. On pressing the associated tab, a module diagnostics window will appear to indicate the source of the fault.
Channel Field
In addition to the Axis choice and Function fields (common to all screens), this zone includes the following commands and LEDs:
Command
Function
Operating mode selector button.
If you wish to change operating mode, click on the name of the new mode to be selected (or click as many times as necessary on the button).
Using the keyboard, select the button with the Tab key, then press as many times as is necessary on the Space Bar.
It is also possible to access operating modes using the View menu.
When the selected mode is taken into account by the module, the movement monitoring zone for that mode is displayed.
Caution: Even though selected, the module channel may not take the mode into account (e.g. if the PLC is in STOP mode).
Forcing command menu.
If an object can be forced, a right click on the corresponding button (1) displays a menu (2) which allows access to the forcing commands: Forcing to 0, Forcing to 1 or Unforcing.
After clicking on a command to select it, forcing is applied and the forcing status is indicated by the button (3):
  • F for forcing to 0
  • F in inverse video for forcing to 1.
The Global unforcing button in the module zone is used to unforce a set of forced objects.
This zone displays a summary (with background on certain points similar to an oscilloscope) of the value of the analog output.
This value is between +10 V and –10 V.
CHi
Lit: Configured non-faulty axis (channel).
Blinking: Faulty axis.
Off: Non-configured axis.
DIAG
Lit: Channel fault.
By pressing on the button associated with this LED, a dialog box appears, specifying the source of the fault.
