We encountered a problem with the CP1W-TS002 temperature module as temperatures are not displaying correctly on the HMI. Despite replacing the module with a new one, the issue persists. We are utilizing the CP1H-X40DT1-D CPU and require assistance in troubleshooting the problem.
Ensure that the dip switches on the CPU have not been tampered with, as this can impact communication to the board. You can refer to the manual for instructions on how to check and adjust the dip switches: https://www.myomron.com/downloads/1.Manuals/PLCs/UNITS%20CJ_CP_NJ/W516%20(Section10)%20CP1L-EL_EM%20Analog%20Option%20Boards.pdf.
It sounds like you've ruled out a hardware issue by replacing the module, which is a good first step. Incorrect readings could be a calibration problem or a programming error. Could you check if the scaling parameters for the temperature conversion in your PLC program for the HMI are correct? Also, ensure that the wiring setup from the module to the HMI is properly connected. If the issue persists, you might want to consider resetting your CPU or updating the firmware, if an update is available.
It sounds like the issue might not be with the temperature module itself since you've already replaced it. Have you checked the communication settings between your CP1W-TS002 temperature module and the CP1H-X40DT1-D CPU? There may be some incompatibility there, considering this persistent issue. The manual for the CPU might provide some guidance on the appropriate settings. If that doesn't work, the problem might also be with the wires or connectors. Remember to use shielded wires for temperature sensors and ensure it's correctly connected.
It sounds like a frustrating situation! Have you checked the wiring and connections between the CP1W-TS002 module and the CPU? Sometimes intermittent connections can cause erratic readings. Also, make sure the correct parameters are set in the programming for temperature scaling and offset, as that could lead to inaccurate displays. If everything seems fine on that end, it might be worth investigating if there’s a firmware update available for your CPU that might resolve compatibility issues. Good luck!
It sounds frustrating to deal with persistent issues like that! Have you checked the wiring connections between the temperature module and the CPU? Sometimes, minor loose connections can cause inaccurate readings. Additionally, ensure that the configuration settings in your HMI are correctly aligned with the specifications for the CP1W-TS002. If those all check out, it might also be worth looking into possible interference or calibration errors, as those could also be culprits for the odd readings.
