When the first data link status word for manually set data link tables or for automatically set data links is not set
or is set to 0, the data link status is stored in the words shown below.
8-Bit Format Specified
The numbers in the squares indicate node addresses.
The corresponding node participation status is as follows:
0: Not part of the network
1: Part of the network

Data link participation
0: Not in data link or data link inactive
1: In data link
Offset error
0: Normal
1: Error Error: Offset exceeds
number of send words.
Insufficient (short) receive area
0: Sufficient
1: Insufficient Insufficient: Receive
area is smaller than
send area. Excess data
is truncated; other data
is received.
Remaining receive area
0: Not remaining
1: Remaining Remaining: Receive
area is larger than send
area. Data is received
and remaining words
are cleared.

Note When a data link with node addresses
higher than 32 is required, specify the
beginning storage word rather than us-
ing the default.
(In this case, a 31 word area is used
when the 8-bit format is specified.)
