Abstract
A central processing unit in a programmable controller is connectable to a plurality of logging devices to detect a trigger to log control data about device control. The central processing unit includes a bus communicator that receives a first trigger signal indicating the trigger from a first logging device of the plurality of logging devices, and a trigger relay that transmits the first trigger signal to a second logging device different from the first logging device when the first trigger signal is received. The trigger relay excludes, from a transmission target, a second trigger signal different from the first trigger signal and received in a period from when the first trigger signal is received to when the trigger relay completes transmitting the first trigger signal.
