Status Area and Troubleshooting Section 9-2
Communications error is 1:
ON The relevant node is not in
the Network. Enter the node in the Net-
work.
A communications error
has occurred as a result of
noise. Conduct an echoback test
using the Controller Link
Support Software and if
this does not correct the
error, check the usage
environment.
A communications error
has occurred. Refer to page 287 Trouble-
shooting with RUN, ERC,
ERH and INS Indicators
and troubleshoot accord-
ingly.
Data link participation is 0:
OFF The relevant node is not
part of data links. Enter the relevant node in
data links. If an error
occurs, refer to page 291
Node Cannot Participate in
Data Link and troubleshoot
accordingly.
There are no active data
links in the Network. Activate the data links.
Offset error is 1: ON The offset is greater than
the number of send words
at the relevant node. 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.
Receive area insufficient
(short) is 1: ON The send area at the rele-
vant node is larger than the
receive area and some
data cannot be received. 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.
Receive area remaining is
1: ON The send area at the rele-
vant node is smaller than
the receive area and some
of the area will be unused. 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.
