7-3-7 DATA LINK STATUS READ

Command Block
Response Block
136
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.

Data link data error counter (response): The total number of data link data
reception errors occurring at all nodes (node addresses 1 to 32) 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).

Status flag
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
