Parameters

Power Status Internal Parameter, Read-only, Analog (signed 16-bit integer)
-0.0 V to 32.8 V

Either the actual supply voltage or the supply voltage status (depending on whether universal inputs are fitted). Unsupported on the dwM3.
-1 = Not Available
0 = Fail
1 = OK
Timebase Setpoint Internal Parameter, Read-only, Analog (signed 16-bit integer)
3 ms to 10000 ms

Desired cycle time. It is recommended that the this parameter be set approximately 15ms longer than the execute time (normally 30ms or greater).
Timebase Measured Internal Parameter, Read-only, Analog (signed 16-bit integer)
0 ms to 32767 ms

Unfiltered cycle time. This includes the FBE execution time and the overhead (e.g. I/O Modbus, etc.)
Execute Time Internal Parameter, Read-only, Analog (signed 16-bit integer)
0 ms to 32767 ms

Unfiltered execute time. This is the FBE execution time ignoring overhead.
0 = <1 ms
Program Line Number Internal Parameter, Read-only, Analog (signed 16-bit integer)
0 to 512

Length of program or line at which load error occurred
