5-1 Basic Examples of PID Control
This section shows basic examples of how to connect the function blocks
when performing PID control.
5-1-1
Simple PID Control
Function block used: Basic PID (Block Model 011)
Use the Field I/O Terminal blocks (AI 4-point/AO 4-point Terminal blocks,
etc.) as the analog input/outputs.
