Digitax ST Advanced User Guide 193
Issue Number: 1 www.controltechniques.com
The priority levels of different tasks may be changed with this parameter. The parameter is accessed in a bit-wise manner:
Specifies the DPL program line number that caused a run-time error. This is valid only when:
• The user program has been compiled with the debug option set.
• The error is one that can be generated by user code, for example divide by zero (50) or parameter does not exist (41).
If both of these conditions are not met, the line number parameter will display zero (0).
This parameter is available for the user to put in an ID code of their program. This may, for example, be the software version number. Use the function
block SETUSERID() to write to this parameter.
When a run-time error occurs the error number is placed into this parameter.
For more information, see Section 11.1 Run-time Errors in the SM-Applications Modules and Motion Processors User Guide.
*See trip SLX.Er, Automation (I/O Expansion) module category on page 134.
