Communication error information
It is possible to check the conditions of the communication and the error log. It is also possible to initialize the connection status for each Station
No.
- Bit 1: Initialization
Writing 1 initializes all values related to error information and communication error information for each Station No. When
the value turns to 0 after 1 is written, this indicates that initialization is complete.
When “Auto retry” is disabled, communication is not made with the Station No. where the communication error occurred,
but if this bit is used for initialization, communication is resumed with all Station No.'s.
- Bit 4: Conditions under which the error occurred
If an error is occurring at a Station No., this bit turns to 1.
When the system recovers from the communication error, it automatically turns to 0. It is always 0 when “Auto retry” is dis-
abled. When the Bit 0 (connection settings) of the “Communication error information for each Station No.” settings is 0, the
conditions under which the error occurred at each Station No. are not reflected in this bit.
- Bit 6: Read error log
If a read error occurs on a device used on the MICRO/I or Touch, 1 is written.
It will not change to 0 even after the system recovers from the read error. To make it 0, write 1 in the Bit 1 (initialization).
- Bit 7: Write error log
If a write error occurs on a device used on the MICRO/I or Touch, 1 is written.
It will not change to 0 even after the system recovers from the write error. To make it 0, write 1 in the Bit 1 (initialization).
