Data Link Status: abyDataLinkStatus [ ]
Bit status Probable cause Probable remedy
PC’s CPU Unit error is 1: ON
A fatal PC error, non-fatal PC error,
or a watchdog timer error has
occurred. Refer to the PC’s operation manual
and correct the error. If the error
occurs again, replace the PC.
The Unit is mounted to a
non-compatible PC. Mount onto the correct PC.
Data Link Communications Error
Status is 1: ON
The relevant node is not in the
Network. Enter the node in the Network.
s s O
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 9-1-1 Using the RUN,
ERR, and INS Indicators and
troubleshoot accordingly.
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 127, 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 short is 1: ON The send area at the relevant 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 offset, then
reset the data link table correctly.
Receive area remaining is 1: ON The send area at the relevant 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 unspecified data.)
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 correctly.
Note Data link status can also be monitored from the CLK Data Link Setting Utility.

Error log exists is 1: ON Error information on the Controller
Link Support Board (an error log) has
been recorded. Using the Controller Link Support
Software or an FINS command, read
the cause of the current error.
Alternatively, use past error log
records to troubleshoot the problem.
Communications controller send error
is 1: ON The Controller Link Support Board is
faulty. Replace the Controller Link Support
Board.
