I have a problems with signals in a KUKA robot not running the RCS but the MOP for PLC simulation purposes. I am running Process Simulate v13 with Kuka contoller version v8.3 in PLC Simulation mode
I can set a signal ie $OUT = TRUE and will see it evaluated in the Simulation Monitor correctly, but when I try to evaluate a signal ie IF ($OUT<>$IN) then it says both signals not found and assumes 0
Yes I am running line simulation, and have done all the robot signal mapping.
I have found that if a signal is not initialised ie does not have a value assigned to it at the start, PS will say signal not found, but this does not explain in the example $B_OUT not holding its value.
I have also found found further issues with PS evaluating signals, for example if I have an IF statement such as IF($B_OUT[OFFSET+I] ==0) PS process this seperatley as '$B_OUT[OFFSET' and 'I]'.
If this is a signal assignment ie $_B_OUT[OFFSET+I]=123 this works and the value in the square bracket is evaluated correctly before assignment.
