1. GENERAL DESCRIPTION
There are the following PID control instructions.
Classification
PID control data setting
PID operation
PID control status monitor
Specified loop No. operation stop
Specified loop No. operation start
Specified loop No. parameter change
PID control via PID control instructions is implemented by combining the CPU module
with the A/D converter module and D/A converter module.
In the case of the QnACPU, the PID control status can be monitored using the
AD57(S1) CRT controller module.
POINT
(1) The Process CPU is not compatible with the PID control instructions described
in this manual.
To implement PID control using the Process CPU, use the process control
instructions described in the QnPHCPU/QnPRHCPU Programming Manual
(Process Control Instructions).
(2) The Redundant CPU can use the PID control instructions and process control
instructions.
