I'm trying to control an extended axis with a PLC. I'm using the $SCR_GRP.$MCH_ANG system variable, but it's not working. I use the variable to read the data on axis number 5, but i don't know if i could write to the variable, in terms of controlling it?
I've tried and when i write to it, the axis doesn't move in ROBOGUIDE, but the variable is changed to the correct value, when i check under system variables.
Any suggestions or alternatives to do the job?
Can the problem cause that the robot isn't in run?
I have created a BG Logix program to run the code continuously:
4: !Mapping the skirt position to the PLC
6: GO[30:RGSkirtPos ]=($SCR_GRP.$MCH_ANG)
8: !Skirt Control
