Communication error information for each Station Number
The “Communication error Information” setting stores all communication error information. To refer to error information for each Station No., use
this setting. “Communication error information for each Station No.” occupies the same number of devices as the set number of words for each Host
I/F Driver or Communication Driver, starting with the set device first.
- Bit 0: Connection settings
Instructs whether or not to communicate with the relevant Station No.
Communication is made if this bit is 1. Communication is not made if this bit is 0.
When the power is turned on, the default value of this bit is 1.
When “Auto retry” is enabled, this bit is always 1.
When “Auto retry” is disabled, this bit is 0 if a communication error occurs.
- Bit 4: Conditions under which the error occurred
This bit turns to 1 when an error is occurring at a relevant Station No.
When the system recovers from the communication error, it automatically turns to 0.
- Bit 6: Read error log
If a read error occurs at a relevant Station No., 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) of
the communication error information.
- Bit 7: Write error log
If a write error occurs at a relevant Station No., 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) of
the communication error information.
