Commands and Responses for the Support Board
Section 6-3
Polling node address (response):
The current polling node address is
returned in hexadecimal.
Data link operation (response):
Indicates the status of data link operation in
the network.
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 parameter is valid only during data link operation. While data link opera-
tion is inactive, the value from the previous operation is retained.
Data link recurring error status (response):
Indicates whether an error
continues to occur at a node when data link data is received. If an error con-
tinues to occur at the same node when the data is received, the bit corre-
sponding to that node turns to “1” (i.e., turns ON). The configuration is shown
in the following diagram.
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 hexa-
decimal, as one byte per node. The count can range from 0 to 255 (i.e., 0 to
FF in hexadecimal).

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.
