I have successfully connected the analog modules EM231 & EM232 to my PLC CPU 216-2. However, I encountered an issue when accessing PLC information in Microwin. The module status displays an error message stating "no user power/module error." Both modules have a red light on and are not producing any output. As a beginner in PLC programming, I am seeking assistance to resolve this issue. Any guidance or support would be greatly appreciated. Thank you.
If you see the error message "no user power/module error," the solution likely lies in checking the 24V supply to the module at terminals L+ and M.
Hey there! It sounds like you've done a solid job in getting those modules connected. For the problem related to "no user power/module error," it might be connected to a power supply issue, or maybe a faulty module. Try checking if your power supply is adequate and functioning properly. Also, it could be beneficial to inspect the wiring for any issues. Alternately, you could try substitifying the questionable modules with known good ones to see if that resolves the issue. Keep going, learning PLC can be tricky at first, but you'll get the hang of it!
It sounds like a power supply issue, as the red light typically indicates a problem with module power. You might want to ensure that your PLC's power supply can handle the extra modules, as it could be overloaded. Also, double-check your wiring and connections to confirm that they're correct and securely connected. Servicing your system might also be required if there's a deeper issue with your modules or PLC. If these tips don't help, please upload some pictures or details of your setup, that would make it easier to assist you further. Good luck!
It sounds like you're on the right track with your PLC setup, but that error message suggests there might be an issue with either power supply or module configuration. First, double-check that the EM231 and EM232 modules are correctly seated and that all power connections are secure. Then, confirm that your power supply is adequate and compatible with the modules. Sometimes, even a simple wiring mistake can lead to these error lights. If everything looks good, it might be worth reviewing the configuration settings in MicroWIN to ensure the modules are properly recognized. Don't hesitate to consult the manuals for both the PLC and the modules—they can provide valuable troubleshooting tips specific to your situation! Good luck!
It sounds like you're facing a common issue with power supply or module configuration. First, double-check that both analog modules are receiving adequate power from your PLC setup; sometimes, connections can come loose or be improperly seated. Also, ensure that you've configured the modules correctly in the MicroWin software—selecting the right type of modules and configuring the parameters properly can often resolve these types of errors. If everything seems fine on the hardware side, consider looking into the wiring for any short circuits or incorrect connections. Don't hesitate to consult the user manuals for both the modules and the PLC, as they often contain troubleshooting sections that can be really helpful. Good luck!
