Position proportional control
The following shows the relation among the setting, error, and the operation of the CPU module.
Status
HOLD/CLEAR setting
PID continuation flag
CPU module status RUN
Stop error
Operation of the RUNSTOP
CPU module
Resetting
*1
Disconnection
*1 When the module is mounted together with a remote head module
Precautions
• Fully pay attention to the settings of "PID continuation Flag" of "Control basic parameters" in "Application Setting" and
"Valve operation setting (When CPU stop)" of "Position-proportional control setting" in "Application Setting" for controlling
external outputs.
• Depending on an output element failure or an internal circuit failure, an abnormal output may occur. Configure an external
circuit for monitoring output signals that could cause a serious accident.
Setting method
Configure the setting as follows:
