The access log 1 can be read.
(1) Usage
By using this object, the access log 1 can be read.
The access log 1 displays the address that was last accessed successfully in Modbus communication.
Access log 1
Higher 2 bytes
Lower 2 bytes
For example, if access to the input device status (Index: 2C12h) is successful, the read value of access

The access log2 can be read.
(1) Usage
By using this object, the access log2 can be read.
The access log 2 displays the number of addresses that were last accessed successfully in Modbus
communication.
Use this when an access error has occurred in the continuous read/write.
For example, when an error occurs during continuous reading of the monitor (Index: 2B01h to 2B0Ah), if
the read value of the access log 2 is "0006h", an error that occurred at address 2B07h can be
determined.
