(1) RUN LED
(a) When turned off
If the above action does not solve the problem, perform a unit test on the Ethernet adapter module to check for
hardware failure. ( Page 57, Section 6.3)
(b) When flashing
If the above does not solve the problem, perform a unit test on the Ethernet adapter module to check for
hardware failure. ( Page 57, Section 6.3)
Checking Action
Is the Ethernet adapter module in execution of a unit test?
If the MODE LED is flashing, a unit test is being performed. Reset the
Ethernet adapter module, or turn off the power and then on.
Checking Action
Is the switch of the Ethernet adapter module set to RUN? Set the switch of the Ethernet adapter module to RUN to start data link.
Is the module in the remote STOP status? Cancel the remote STOP and start data link.
Is the master station in the RUN status?
Place the master station into the RUN state. If the master station has
stopped due to an error, troubleshoot it referring to the manual for the
master station. ( User's manual for the master/local module used)
Was the Ethernet adapter module disconnected while the
master station was in the STOP status?
• Place the master station into the RUN state, and reconnect the
Ethernet adapter module to the network.
• Reset the Ethernet adapter module since it retains the STOP status
data of the master station.
