Commands and Responses for Controller Link Units

Section 6-5

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

 

For Wired Units: 0: Terminating resistance OFF

3 Hex: 500 Kbps

 

 

1: Terminating resistance ON

 

 

 

 

 

Status 3 (response): Error information. The configuration is as follows:

Bit 7 6 5 4 3 2 1 0

0

1:Error log exists

1:Data link error stop

1:Controller transmitter error

1: Node address setting error

1:Duplicate node address setting error

1:Network parameter error (See note.)

1:Controller hardware error

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:

Bit

7

6

5

4

3

2

1

0

0 0

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)

1:Network parameter error

1:Data link table error

1:Routing table error

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.
