CH Error history
■Description
Error history  (address: 0A00H to 0AEFH) records up to 15 errors generated in the module.
Error history 2 (address: 0A10H to 0A1FH) to Error history 15 (address: 0AE0H to 0AEFH) store data in the
same format as that of Error history 1 (address: 0A00H to 0A0FH).
For the error code, refer to the following.
Page 21 List of Remote Buffer Memory Areas
The following table shows the contents stored in Error history 1 (address: 0A00H to 0A0FH).

*1 This example shows the values when a second error occurred at 13:30:50, September 1st, 2012.
*2 The clock information of the error that occurred is based on the clock information acquired from the CPU module of the master station.
When an error has occurred before the clock information is acquired from the CPU module, the error time is not recorded.
