Section 9-2
Note
Data link status is valid only when the local node is participating in the data
link. Confirm that the Local Data Link Active Bit is ON before referencing the
data link status.
The statuses of bits 12 to 14 are reflected only when using a CS1W-CLK21-
V1, CS1W-CLK23, CJ1W-CLK21-V1, or CJ1W-CLK23.

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

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.)
