Digital PID algorithm


Thread Starter



I need PID control block for GE Fanuc PLC 90-30 for digital output. I have analogue pressure input to PLC. Based on setpoint and PID control block i need two digital output to control the solenoid of a pressure regulator.
Anybody who can help?
You can use the CV of PID to perform 2 PWM outputs, increase and decrase functions. Two timers with a variable preset values can build A simple PWM function. I have made it succesfully.
