user32767 Posted January 22 Report Share Posted January 22 Hello. I have a Unitronics USC-x5-TR22 PLC, UMD-0010C-B3 drive, and a motor, connected to conveyor. This whole setup needs to be calibrated so that when I command to move conveyor belt by 1000 mm it would really move by 1000mm, not 995 or 1005. Right now I do this in Unitronics UniLogic, adjusting parameter "Roller Diameter" in actuator parameters, but I'd like to be able to do it from program code. The problem is that "Roller Diameter" is just a settings paameter, not a program tag, so I can't access it from program code. I could achieve the very same effect adjusting ratio of "Position_factor_numerator" / "Position_factor_denominator", which are tags and can be accessed from program, but they seem to be read-only, so I can't change them. Could you please give me a hint where should I look for solution? Best regards, user32767 Quote Link to comment Share on other sites More sharing options...
user32767 Posted January 22 Author Report Share Posted January 22 As it turns out, I shouldn't try to write directly in this tags. Instead, I should use MC_Write for this purpose. Sorry for silly question. I would mark this topic as "solved", but I don't know how. Quote Link to comment Share on other sites More sharing options...
