*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.
• The error history registers 15 errors at a maximum. If 16 or more errors occur, errors are deleted from the
oldest.
• If the same error occurs continuously, only the error that occurred latest is stored to the error history. Thus,
"Order of occurrence No." and "Error time" of the error history are updated at the timing an error occurs.
• Even after the module power supply is turned off and on, the error history remains.
• The clock information of the error that occurred is based on the clock information acquired from the Safety
CPU of the master station. To obtain the exact occurrence time of an error, set the clock information of the
Safety CPU to the actual time.
• To initialize the error history, set "Method selection" to "Error history clear request" on the "Command
Execution of Slave Station" window and click the [Execute] button.
