Assumed cause Correction Prevention
The communications cable is broken. Check the communications cable and
replace it if it is broken.
Check the communications cable to
see if it is operating properly.
Attached
information
The communications cable connec-
tor is disconnected.
Reconnect the connector and make
sure it is mated correctly.
Make sure the communications cable
is connected properly.
The NX message communications
load is high.
Reduce the number of times that
instructions are used to send NX
messages. Or, increase the value of
the TimeOut input variable to the
instruction. If more than one copy of
the Sysmac Studio is connected,
reduce the frequency of simultaneous
operations.
