Note: Errors other than those listed above are detected by the detector on the command transmission side. Refer to the Instruction Manual for that
device for details.
Note: If the error status flag (RX(n+1)A) is set once to “ 1 ” (ON), the error status flag will not be set to “ 0 ” (OFF) even if the CPU of PLC is reset.
To set the error status flag to “ 0 ” (OFF), set the error reset status flag (RY(n+1)A) to “ 1 ” (ON).
However, even if the error status is released when the error reset status flag is set to
“
1
”
(ON), if there is an error in the retransmitted data, the
error status flag will once again be set to “ 1 ” (ON). Therefore, refer to the error code and eliminate the cause of the error prior to retransmitting.
10.7 Troubleshooting
Check the following if your device appears to be failing.
(1) Is the MDU applied control power?
(2) Nothing is displayed on the display.
Is the connection cable connector fully plugged in? Is it disconnected?
(3) The device is powered but the current is 0 A.
If the electric current measurement value is less than the measurement lower limit current (less than ± 1.0% of the measurement rated current),
it is cutoff so that the display value is 0 A.
(4) Unable to monitor when transmitting/communicating even though a value is displayed on the display.
[1] With CC-Link communication
• Confirm that there are no errors in the communication line connection, and that no wires are disconnected.
• Are there any stations with the same station number on the same transmission route? If there are, configure the correct station number and
then press the reset switch.
• Is the communication speed set to the same value as the master device? If it is different, configure the correct communication speed and then
press the reset switch.
(5) The electric current value measured by the device differs from other measurement values. (Permissible error value or greater.)
• Confirm that the measurement instrument used for comparison measures the effective value correctly. The device indicates the effective value.
• If the measurement instrument used for comparison measures the average value instead of the effective value, distortion in the current flowing
through the measurement circuit will create a significant difference.
