Status Area and Troubleshooting
Section 10-2
Network Participation Status: CIO 1500 + 25 x
(Unit No.) + 2 to + 5
Local Data Link Participation Status: CIO 1500 + 25 x
(Unit No.) + 6
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.
Data Link Status: CIO 1500 + 25 x
(Unit No.) + 7 to + 22
8 Bit Format Specified
The numbers in the squares correspond to node addresses.
The bit status indicates each node's participation status as follows:
0: Not part of the network
1: Part of the network
Note When the local node is not part of the network, the local
node's participation status bit will be 0. The participa-
tion status of other nodes will not be reliable in this
case.
−
: Not used
1: Local node data link participating
0: Local node data link not participating or data link
inactive
PLC status
0: Inactive (user program not running)
1: Active (user program running)
Communications error (data link reception)
0: Normal
1: Error
PLC's CPU Unit error
0: Normal
1: Error
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.)
