• Registering or changing the PID control data per sequence program scan will present no problem. However,
execute the the PID control data setting instructions
data. If you do not execute the PID control data setting instructions instruction, the data registered or the
correction made to the PID control data will not be reflected at the execution of the the PID operation
instructions.
• You need not execute the PID control data setting instructions when using the parameter change instruction
*3
to change the PID control data per loop.
*1 The following instructions are available as the PID operation instructions.
S.PIDCONT (incomplete derivative)
