Why is the ERROR/ALARM LED flashing on my Panasonic Control Unit?

  If the ERROR/ALARM LED is flashing, use the programming software to check the error code. In online mode, monitor the PLC status, or find the error code in the 'Self-diagnostic error' section. You can also try to clear the error by choosing [Clear] in the 'PLC status' dialog while in PROG mode. Another solution is to turn the power supply off and on while in PROG mode, which clears the operation memory (except hold type data). Finally, you can execute the self-diagnostic error set instruction F148_ERR.

What to do if all LEDs are OFF on my Panasonic Control Unit?

  If all the LEDs are off, start by checking the power supply wiring and ensure that the power supplied to the CPU is within the rated range, accounting for any fluctuations. If the CPU shares a power supply with other devices, disconnect their wiring. If the CPU LEDs turn on after disconnecting other devices, either increase the capacity of the power supply or use a separate power supply for the other devices.

How to diagnose output malfunction in Panasonic Control Unit?
- E
  elizabethfrancoAug 8, 2025
  Diagnosing an output malfunction involves checking both software (program, I/O allocation) and hardware (wiring, power supply). Start by checking the output side, then the input side. If the output status LEDs are ON, check the wiring of the loads and ensure power is properly supplied to them. If power is supplied but the load isn't working, there may be an issue with the load itself. If the output status LEDs are OFF, monitor the output condition using Control FPWIN Pro. If the output monitored is TRUE, there may be a duplicate output error. You can also try setting the output to TRUE by force using Control FPWIN Pro. If the output status LED turns ON after forcing it, you need to check the input side. If the LED remains OFF, there is likely an abnormality with the outputs.

  If the ERROR/ALARM LED is continuously ON, it could be due to several reasons. The system watchdog timer might have been activated; if so, set the mode selector from RUN to PROG mode and cycle the power. Also, check if the program execution time is too long and set the mode selector from PROG to RUN mode. Ensure instructions like JP or LOOP are not programmed in a way that prevents a scan from finishing, and verify that interrupt instructions are not executed in succession. Also check if the ERROR/ALARM LED is flashing.

What to do if the input status LEDs are OFF on my Panasonic Control Unit?

  If the input status LEDs are OFF, first check the wiring of the input devices and ensure that power is properly supplied to the input terminals. If power is correctly supplied, there may be an issue with the inputs themselves. If power is not reaching the input terminal, there is likely a problem with the input device or its power supply. Check both the input device and its power supply.

  If the input status LEDs are ON, monitor the input condition using Control FPWIN Pro. If the input monitored is FALSE, there is probably an abnormality with the inputs. If the input monitored is TRUE, check the leakage current at the input devices (e.g., two-wire type sensor) and review the program. Also, check for duplicate output errors and outputs rewritten by high-level instructions. Verify the program flow when using instructions like MC or JP, and ensure the I/O map matches the actual mounting status.

Why won't my Panasonic Control Unit PROG mode change to RUN?
- V
  vrobersonAug 26, 2025
  If the PROG mode does not change to RUN, a syntax error or a self-diagnostic error might have stopped the operation. Check if the ERROR/ALARM LED is flashing. Locate the syntax error by executing Monitor ? PLC status.
