S7-315
I have inherited a job that someone else designed and started. It has Hydraulic Servos 0-10v from an analog OP card and Encoders back to an FM350 High speed counter module.
Now I've done this same application successfully in a 1500 CPU using the technology motion control functions, but I have never attempted to do it with code.
The code has been written using continuous PID controllers, I've started commissioning and the servos drive but the motors are sloppy and not accurate enough.
My question is:
Is this actually possible or should I throw the CPU away and start again with an S7-1500
