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.
Answer: 1. Q: Why are temperatures not displaying correctly on the HMI despite replacing the CP1W-TS002 temperature module with a new one? The issue could be related to compatibility issues between the CP1W-TS002 module and the CP1H-X40DT1-D CPU. It's recommended to check the compatibility and configuration settings to ensure proper communication between the devices.
Answer: Some troubleshooting steps to consider include checking the wiring connections, verifying the sensor inputs, reviewing the programming logic, updating firmware if necessary, and ensuring proper power supply to the devices.
Answer: Yes, it's important to ensure that the programming logic for reading and displaying temperature values is correctly implemented in the PLC program. Additionally, calibration settings and scaling factors may need to be adjusted for accurate temperature readings.
Answer: Yes, you can perform a standalone test of the CP1W-TS002 module by connecting it to a separate monitoring device
