Description
Indicates if the PC program is being executed or not.
Always 1 for Controller Link Support Board nodes.
Indicates if an error has occurred in the PC.
Always 0 for Controller Link Support Board nodes.
Indicates if data link data for node was received normally or
not.
Indicates data link participation status.
"Error" indicates that the offset is larger than the number of
send words. The data links will operate and the node will
remain participating in the data links. The receive area at
nodes with this error will be all zeros.
A receive area is "remaining" if the number of words in the
receive area is larger than the number of send words. Data
will be received normally and all words in the receive area
beyond those containing the send words will have
indeterminate status.
A receive area is "short" if the number of send words is larger
than the number of words in the receive area. Data will be
received normally, but all words that will not fit in the receive
area will be discarded.
Remaining

is received in node 2 and the
