Commands and Responses for Controller Link Units

Section 6-5

Data link data error counter (response): The total number of data link data reception errors occurring at all nodes is returned as a total count from the time the power was turned on. It is expressed, in hexadecimal, as one byte per node. The count can range from 0 to 255 (i.e., 0 to FF in hexadecimal).

Byte 1 Number of error occurrences for node #1

Byte 2 Number of error occurrences for node #2

Byte 3 Number of error occurrences for node #3

Byte 32 Number of error occurrences for node #32

Byte 33 Number of error occurrences for node #33

Byte 62 Number of error occurrences for node #62

When CS1W-CLK21-V1 and CJ1W-CLK21-V1 Units are used and the Wired Network 62 Node Enable Bit in the DM Parameter Area software switches is ON, the data link error counter of nodes 33 to 62 is returned in bytes 33 through 62. In other models, the areas corresponding to nodes 33 to 62 are reserved for system use.

Status

 

Note If the type is set to 0000 Hex (or is omitted), only 32 bytes will be returned.

Parameters

Type (Command): The number of nodes reading the data link status is spec-

 

ified as a 2-byte (4-digit) hexadecimal number as follows:

 

0000 Hex: 32 nodes

 

0001 Hex: 62 nodes

 

Default value: 32 nodes

 

Reading of the data link status for 62 nodes is enabled only when the Wired

 

Network 62 Node Enable Bit in the DM Parameter Area software switches of

 

CS1W-CLK21-V1 and CJ1W-CLK21-V1 Units is ON.
