Commands and Responses for Controller Link Units
1: Error log exists
1: Data link error stop
1: Controller transmitter error
204
Status 2 (response): For C200HX/HG/HE, CVM1, and CV-series Controller
Link Units, always set to 00 (Hex). For CS/CJ-series and CQM1H-series
PLCs, the Unit's setting status is returning in the following configuration.
Bit
Baud rate:
1 Hex: 2 Mbps
2 Hex: 1 Mbps
3 Hex: 500 Kbps
Status 3 (response): Error information. The configuration is as follows:

0
Note With CS/CJ-series Optical Controller Link Units, this bit will be 1, even if the
Unit is mistakenly connected to an Optical SYSMAC LINK Network.
Status 5 (response): Error information related to the Unit and the PLC. The
configuration is as follows:
1: EEPROM error
1: PLC model error
(C200HX/HG/HE only)
1: PLC system setting error
(CS/CJ-series, CVM1, and CV-series PLCs only)
A network parameter error, data link table error, or routing table error occurs if
an error is discovered when the parameters and tables are checked at power
up.
A PLC system setting errors occurs if the Controller Link Unit is not properly
recognized by a CS/CJ-series, CVM1, or CV-series PLC.
A PLC model error occurs if a C200HX/HG/HE Controller Link Unit is
mounted to another type of PLC.
Count 1 to Count 8 (response): The total number of times for each of the
items listed below is returned as 1 byte of hexadecimal data.
Count 1: Number of CRC errors
Count 2: Number of token re-sends
Count 3: Number of token returns
Count 4: Number of token timeouts
Count 5: Number of polling timeouts
Count 6: Number of controller changes
Count 7: Number of active node changes
Count 8: Reserved for system use.
For Wired Units:
0
1: Node address setting error
1: Duplicate node address setting error
1: Network parameter error (See note.)
