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).
When CS1W-CLK21-V1, CS1W-CLK23, CJ1W-CLK21-V1, and CJ1W-CLK23
Units are used and the Wired Network 62 Node Enable Bit in the DM Parame-
ter 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.

DATA LINK STATUS READ
Reads the data link operational status.

Response Block
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, CS1W-CLK23, CJ1W-CLK21-V1, and CJ1W-CLK23 Units
is ON.
