Bit status
Communications error is 1:
ON
Data link participation is 0:
OFF
Offset error is 1: ON
Receive area insufficient
(short) is 1: ON
Receive area remaining is
1: ON
Probable cause
The relevant node is not in
the Network.
A communications error
has occurred as a result of
noise.
A communications error
has occurred.
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.
Section 9-2
Probable remedy
Enter the node in the Net-
work.
Conduct an echoback test
using the Controller Link
Support Software and if
this does not correct the
error, check the usage
environment.
Refer to page 287 Trouble-
shooting with RUN, ERC,
ERH and INS Indicators
and troubleshoot accord-
ingly.
Enter the relevant node in
data links. If an error
occurs, refer to page 291
Node Cannot Participate in
Data Link and troubleshoot
accordingly.
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 offset, 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 off-
set, then reset the data link
table correctly.
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 off-
set, then reset the data link
table correctly.
