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.
Note When the square root function is used in flowrate control, insert the Square
Root block (Block Model 131) in analog input.
5-1-2 Multi-channel PID Control
Function blocks used: Basic PID (Block Model 011)
Constant ITEM Setting (Block Model 171)
Step Ladder Program (Block Model 301)
