6-3 Section Commands and Responses for the Support Board

Data link operation (response): Indicates the status of data link operation in
the network.

Data link operational status
0: Inactive
1: Active

Data link type (response): Indicates the data transmission status of the source
node’s data links. It is configured as shown in the following diagram. This param-
eter is valid only during data link operation. While data link operation is inactive,
the value from the previous operation is retained.
Bit
Source node data transmission status
0: Transmission
1: No transmission

6 5 4 3 2 1 0
0 0 0 0 0 0
Data link recurring error status (response): Indicates whether an error con-
tinues to occur at a node when data link data is received. If an error continues to
occur at the same node when the data is received, the bit corresponding to that
node turns to “1” (i.e., turns ON). The configuration is shown in the following dia-
gram.

The numbers in the boxes indicate the node
addresses. The bit status of a particular
node address shows whether or not there is
a recurring data link error at that node.
0: No recurring error
1: Recurring error
Reserved for
system use.

All bytes from 5 to 8 are reserved for Wired Units.
Data link data error counter (response): The total number of data link data
reception errors occurring at all nodes (node addresses 1 to 62) is returned as a
total count from the time the power was turned on. It is expressed, in hexadeci-
mal, as one byte per node. The count can range from 0 to 255 (i.e., 0 to FF in
hexadecimal).
