Howdy.
So I am trying to create a small network of just 2 SLC 5/03's and my programming laptop. The SLCs are connected via RS232 to some 1761-NET-ENI modules, in order to make them ethernet compatible. I am pretty positive that I correctly configured both of them, assigning them different IP addresses and making sure that the other processors are in the message routing table. In RSLinx my drive is the Ethernet devices driver (not the Ethernet/IP driver) and I was able to see straight through the ENI's to the PLCs. The keyword here is "was". I have successfully been able to download to the PLCs previously in the past, only 2 days ago in fact. But when I got back to my set up yesterday, the first SLC wouldn't show up in RSLinx, it would only appear as a NET-ENI. As a result, I can no longer download to that PLC. I believe I have narrowed it down to the PLC, as switching which ENI each one is using provides the same results. I have also noticed that on the downloadable SLC, I see the RS232 indication LED flash every so often, indicating that there is communication, but on the non-downloadable SLC, the RS232 indication LED is totally blank, not lit at all. I have tried factory resetting the NET-ENI's and the results haven't changed. I really don't know what I could have done to the SLC, I've downloaded to it maybe twice, and hardly ever messed around with any of the internal settings I don't think. I suppose I could reset the SLC to factory defaults, but I don't actually know how to do that, and would be afraid that there would be some other settings that I wouldn't know to change. I guess any kind of direction would be much appreciated.
Disclaimer: I apologize beforehand if I was unclear about something, truth be told I am a pretty amateur automator. I am a TA for a PLC/Electrical Maintenance program at my school (yes, it's true, I am one of those dreaded college students), and while I feel that I am pretty alright at raw programming, this networking stuff is really what I need to work on.
Anyways, Any and all advice is always appreciated!
Thanks,
Conor
