Either remote I/O communications, message
communications, or both are being executed.
Status is normal.
If only certain Slave Units show this status,
check that the baud rate is the same and then
restart the Slave Units.
Replace the Slave Unit. Alternatively, check the
Expansion Unit connection.
Check the switch settings then restart the
Slave Units.
Use the CX-Integrator to restore the default
data.
Check that the node address is set within the
allowable range and that it is used only once.
Check the Repeater Unit configuration and
then restart the Slave Units. If the node
address and Repeater Unit configuration are
correct, check the following items, and then
restart the Slave Units.
• Are the baud rates the same for the Master
• Is the cable length (trunk line/branch lines)
• Is the cable disconnected or loose?
• Is there a Terminating Resistor on each end
• Is there too much noise?
Check the following items then restart the
Slave Units:
Is the baud rate the same for the Master Unit
and Slave Units?
Is the cable length (trunk line/branch lines)
OK?
Is the cable disconnected or loose?
Is there a Terminating Resistor on each end of
the trunk line?
Is there too much noise?
Make sure that the node address is set within
the specified range, and then restart the Slave
Unit.
