This is not exactly a plc problem but I know several people here use the RMC100 control.
I have the RMC loaded up with 7 axis so I set up the remaining two analog inputs as a single differential pressure axis. I was able to scale and zero both of them and they work great. Now I need to see when one of them is greater than a set point. I can't do this with the Poll "?" command because it has to reference the position of the axis which is made up of both of the analogs not just one. Is there another way to do this in the step program or do I need to do it in the PLC?
Second question. I am moving a heavy load and I am having trouble getting it to slow down as it comes into position. I need more deceleration so I can start slowing down quicker to prevent overdriving the valve. How do I calculate the decel distance?
