*1 Values of when an error occurs at 10:35:40, August 29th, 2015
*2 The clock information of the error that occurred is based on the clock information acquired from the Safety CPU of the master station.
When an error has occurred before the clock information is acquired from the Safety CPU, the error time is not recorded.
