PID Block Examples
Example 1 - Simplified PID configuration (reference only)
Analog Input block
(or other function block)
PID Block (Simplified)
Output Block (Different types)
• Current
• Time Proportioning
• Three Position Step
• Dual output (2 Output blocks)
• Analog Variable- used to provide an
operator-entered remote setpoint value.
Or,
• Output from other function block (setpoint
programmer)
• Output from other PID block (cascade)
• Enable Ratio/Bias (ratio control)
Remote Setpoint Input:
Alarm Outputs (Digital Signal)
