Status Area and Troubleshooting
Other Status
Bit status
Data link participation is 0:
OFF
Offset error is 1: ON
Receive area insufficient
(short) is 1: ON
Receive area remaining is 1:
ON
Bit status
Error log exists (CIO 1500 + 25 × n,
bit 15) is 1: ON
Communications controller send
error (CIO 1500 + 25 × n, bit 11) is 1:
ON
Inconsistent network parameters
(CIO 1500 + 25 × n, bit 10) is 1: ON
Probable cause
The relevant node is not part
of data links.
There are no active data
links in the Network.
The offset is greater than
the number of send words at
the relevant node.
The send area at the rele-
vant node is larger than the
receive area and some data
cannot be received.
The send area at the rele-
vant node is smaller than
the receive area and some
of the area will be unused.
Probable cause
Error information on the
Controller Link Unit (an
error log) has been
recorded.
The Controller Link Unit
is faulty.
Indicates that the net-
work parameters
recorded in the CPU
Bus Unit Area differ
from the values of the
Network in use.
Section 10-2
Probable remedy
Enter the relevant node in
data links. If an error occurs,
refer to page 212 Node Can-
not Participate in Data Link
and troubleshoot accord-
ingly.
Activate the data links.
Check the number of send
words at the relevant node,
the number of receive words
at the local node and the off-
set, then reset the data link
table correctly.
When the intention is not to
receive all data, use as is
(data that cannot be
received will be read and
discarded.)
When it differs from the
intended data link, check the
number of send words at the
relevant node, the number of
receive words at the local
node and the offset, then
reset the data link table cor-
rectly.
When the intention is to
leave some space in the
receive area, use as is (the
surplus receive area will be
cleared to 0.)
When it differs from the
intended data link, check the
number of send words at the
relevant node, the number of
receive words at the local
node and the offset, then
reset the data link table cor-
rectly.
Probable remedy
Using the Controller
Link Support Software
or an FINS command,
read the cause of the
current error. Alterna-
tively, use past error log
records to troubleshoot
the problem.
Replace the Controller
Link Unit.
Check the network
parameters on the Net-
work in use using the
Controller Link Support
Software, and reset
necessary parameters.
