IF TC018.PVHIFL=ON
& THEN (SET 41HS085.MODATTR=PROGRAM;
& SET 41HS085.OPCMD=OFF;
& SET 41HS085.NMODATTR=OPERATOR;
& SET 41HS085.MODE=MAN;

Hello,

Change this parameter to MODATTR and it should work:

> & SET 41HS085.NMODATTR=OPERATOR;

I hope that is not the complete code, otherwise the program will change the composite point every time it's execute and the hi flag is active.

Regards,

Looks like this parameter needs to be changed in line 4:
& SET 41HS085.NMODATTR=OPERATOR;

To:
& SET 41HS085.MODATTR=OPERATOR;

NMODATTR identifies the normal mode, but doesn't switch modes.

the best thing will be using a logic block to switch the mode to MAN when hi flag comes on. CL will make it P-MAN because you are changing the MODEATTR to PROGRAM.
