Slice I/O Node address
(Hex) No Verify that the Unit is con-
nected properly and turn the
power ON again.
0378 I/O size error 0x00 0x00 No Verify that the Unit is con-

Status Likely cause and remedy
The Communications Unit’s
Unit Power indicator is flash-
ing. The Unit power supply capacity is insufficient. Check the entire Slice I/O Terminal’s power
supply requirement and replace the power supply with one that has sufficient capacity.
The Communications Unit
repeatedly checks indicators
(MS/NS indicator flashing
green and red).
The I/O Unit repeatedly
checks indicators (TS indica-
tor flashing green and red).
The Unit power supply capacity is insufficient. Check the entire Slice I/O Terminal’s power
supply requirement and replace the power supply with one that has sufficient capacity.
The Communications Unit’s
TS indicator flashes green.
The I/O Unit’s indicator in front
of the bad connection lights
green and the indicator
behind the bad connection
goes OFF. The slide connector on the left side of the affected Unit is not connected properly. Connect
this slide connector properly and turn the power ON again.
The Communications Unit’s
TS indicator flashes green
and the I/O Unit’s TS indicator
flashes green. The End Unit is not connected properly. Connect the End Unit properly and turn the power
ON again.
After the Communications
Unit’s MS indicator lights
green, NS indicator lights red
immediately, without flashing. Check the following items and restart the problem Slave.
• A node address is duplicated.
Check all of the node addresses and set them again to eliminate the duplication.
• Check whether the baud rates match on the Master and all Slaves.
If there are any Slaves with different baud rates, set them to the same baud rate.
• See the troubleshooting steps below under the error heading “The NS indicator lights
green but changes to red after a short time.”
• If a particular Slave's NS indicator is always red, replace that Slave.
