GXworks2 can't detect error

[deon1123 0]

I am using gxworks2but it doesn't detect any (Structured text) programming error. And my "check program" is greyed out. Is it normal? When I build all with an major error, it doesn't detect.

Hi deon1123.

The compiler will NOT report any instruction errrors if the necessary POU isnt called in a cyclic task.

Have you got this set up in your main program call?

I dont know about GXW2..but in IEC Developer Land; there will be a small red asterix next to any program that isnt compiled.l, so if you do a complete compile with no errors then this simply means this program has been ignored.

Hi collinsd70,thanks for the reply.

Yes it didnt compile my POU. Is there a setting to allow the POU to be compile/called in?Do advise.

When i click to open un-compiled file,my whole project got highlighted. How to set it to be included in the compile.

Regards

@deon1123: Drag and drop your POU name from POU tree into "Program Setting" (Execution program). Make sure it is listed somewhere under execution program to ensure the code is executed.

@kaare_t Oh thanks but do you know if there is a different between initial,scan ,fixed scan and standby. 

[kaare_t 155]

Yeah:

• Initial is meant for initial processing only (like startup routines)
• Scan is meant for continously scanning (normal code)
• Fixed is meant for a predefined scantime (e.g. scan each 50ms with an interrupt to start)
• Standby is meant for... well... "Standby" (if you have a code that is standing by to take over if someting occurs)

Most likely you'll want to use Scan.
