The error details written here are for the case when Error history is A06H to A09H (for Error history 1 (address: A00H to
A0FH)). The following information of when an error has occurred are stored in this area.
• Error occurrence address
• Process value (PV)
• Manipulated value (MV)
• Set value (SV)
For details on Error history, refer to the following.
Page 363, Appendix 3 (69)

For the area where data can be written only during the module stop, refer to Lists of Remote Buffer Memory Areas.
Page 49, Section 3.7

If the following values are stored in Error occurrence address, 0 is stored in Process value (PV), Manipulated value
(MV), and Set value (SV) of Error history.
0001H, 0007H, 0080H, 0081H, 01E0H to 01EAH, 1000H
*4
represents the channel number where an error has occurred.
When multiple errors have occurred, only the latest error code is stored in Latest error code (RWr0) or Latest warning code
(RWr2).
The errors that occurred in the past can be checked with the error history of the engineering tool.
For the error history, refer to the following.
• Checking with the command execution of slave station (Page 267, Section 11.1 (1))
• Error history (address: A00H to FFFH) (Page 363, Appendix 3 (69))
