From the images you've shared, it appears there might be some communication issues arising due to an IP conflict or incorrect IP assignment respectively within your network. I'd suggest cross-checking the IP addresses first to ensure none are in conflict. Keep in mind for the T_COMM instruction, your network setup may need to be configured accurately, meaning correct TCP port, logical address, and service ID. You might also want to check the Command Field, typically for T_COMM it should generally be set to "Set Attribute Single" for basic operations. If these checks don't resolve the issue, it may be due to a firmware incompatibility.
Given the information you've provided, it seems like there might be a communication issue between your equipment and computer. First, double-check whether all your equipment is on the same subnet as your computer; they should all have IP addresses beginning with 192.168.1. If they do, consider running a ping test from your computer to each piece of equipment to verify network connectivity. Additionally, make sure that there are no firewall settings blocking communications with these IP addresses. If all that checks out, the problem may lie within how you've set up the T_COMM instruction. Could you give more detail on the exact errors you're seeing? This would aid in pinpointing the problem area.
It sounds like you're facing a network communication issue with your setup. First, make sure all devices are configured to be on the same subnet; since your IP is 192.168.1.20, your relay and controllers should ideally be within 192.168.1.x. Also double-check the settings of your T_COMM instruction to ensure they're correctly pointing to the right IP addresses. Sometimes, mismatched communication settings or even firewall configurations on your computer can interfere, so it might be worth disabling your firewall temporarily to see if that resolves the issue. If the problem persists, sharing any specific error codes from your T_COMM could help narrow down the troubleshooting further!
It sounds like you're having some connectivity issues with your T_COMM instruction. First, make sure that all devices, including your relays and controllers, are on the same subnet as your computer. Given your IP setup, both your computer and the equipment should communicate properly. Double-check that the communication settings in your Logix Designer are configured correctly and that there are no firewall settings blocking the communication. Also, ensure that the firmware on your modules is up to date, as sometimes compatibility issues can arise with older versions. If the errors persist, sharing the specific error messages could help narrow down the issue further.
