Defines the action taken if a user DPL program attempts to write an out of range value
to a parameter. When set at 1, a run-time trip will occur (number 44); when set at zero
the value will automatically be limited to the maximum/minimum of that parameter
When set it enables the DPL program watchdog function. The DPL WDOG command
must then be executed every 200 ms. This can be used to protect the program against
malfunction. If the command is not executed within a 200 ms time period the drive will
trip on
SLx.tO. Please note that the WDOG command must also be executed once for
the watchdog to be enabled. This is normally executed at the end of the Initial task.
