Checking Data Link Status
When 8-bit Format is Specified (i.e., when using a C200HX/HG/HE, CVM1, CV-series, or CQM1H-series
PLC or when using a CS/CJ-series PLC with the data link status storage format specification in the DM
Parameter Area set to 8-bit format)

16 words are determined within the status area according to the unit num-
ber setting. When the 8-bit format is specified, therefore, the data that is
reflected will be limited to node addresses 1 to 32.
When data link status is required for node addresses 33 or larger, do not
use the default setting, i.e., specify the first word of the status storage area.
If this is done when an 8-bit format is specified, 31 words will be used as
the status storage area.
participate in the data links. In the node where the offset error occurred,
however, all receive area words will be cleared to 0.

Error: Offset exceeds number of
send words.
Insufficient: Receive area is smaller than
send area. Excess data is truncated; other
data is received.
Remaining: Receive area is larger than
send area. Data is received and remaining
words are cleared.
