My Micro850 PLC is displaying an error with the MS light flashing red and the NS light staying off, while the Ethernet connectivity is not working. How can this issue be resolved?
Welcome to the forum! In the Rockwell industry, a flashing red MS (module status) light typically indicates a recoverable fault. If you have a MicroLogix with USB capability, try using Logix Studio or RSLinx to establish communication via USB.
Alfredo Quintero mentioned: Greetings! In the Rockwell realm, a flashing red MS (module status) typically indicates a recoverable fault. If you're using a MicroLogix with USB capabilities, I suggest checking if you can establish communication through Logix Studio or RSLinx. The issue seems resolved, but there may be a problem with the network status not functioning correctly.
I'm sorry, I'm having trouble grasping the significance of this statement. Has the issue of the MS indicator flashing red been resolved? Are you now facing the problem of the NS indicator being off and the Ethernet not functioning? Have you been able to successfully detect the Micro 850 through USB using RSLINX?
Alfredo Quintero inquired about the resolution of the flashing red MS indicator issue and expressed confusion over the NS indicator being off and Ethernet not functioning. Have you successfully detected the micro 850 through USB using RSLINX? I managed to do so, but I prefer to utilize Ethernet instead.
Could you please provide a screenshot of the Ethernet port properties? Have you set up an appropriate IP address and subnet that is compatible with your PC's IP address? Make sure the IP address is configured correctly for seamless network connectivity.
Based on your description, it seems like your Micro850 PLC is not booting up correctly, possibly due to an issue with the firmware. You could try resetting the controller by turning off the power, waiting a couple of minutes, and then turning it back on. If that doesn't work, you might have to reinstall the firmware. Regarding your Ethernet issue, it might be a hardware error or an incorrect IP setting. Check your cables and your IP configuration, including subnet and gateway. If these solutions don't work, I would recommend getting in touch with tech support.
It seems like this could be a communication issue with your Micro850 PLC. A flashing MS light usually indicates a minor fault, while the NS light being off is typically due to no network or connection. It might be your Ethernet connection that's causing it. Try to check all your network connections, and perhaps reboot your PLC. If the problem still persists, you might need to reset to factory defaults, or you might have a hardware fault that needs further technical attention. Always remember to back up your configuration first before making any major changes.
This issue indicates that your Micro850 PLC may not be establishing a connection to your network. Try to physically check your connections first and replace the Ethernet cable, if necessary. You might also want to check if the IP address is correctly set and is not being used by any other device. Additionally, software-related issues can be resolved by updating the firmware to the latest version or performing a factory reset. But please have a copy of your program before doing so, as this will erase all data in the PLC. Lastly, if everything else fails, you may need to contact Rockwell support for further assistance – it's possible that you might have a hardware issue.
