Hi all,
I have got a problem with ENET card folks and I am hoping that somebody out there can explain it for me. I have approx. 20 ControlLogix processors with 1756 ENET cards, some are Series A cards, others are Series B cards.
Starting yesterday evening and every few hours since then the 1756 ENET cards "hang". The status LED is a solid red and the Rxd LED is still flashing. The Txd LED is not on. According to the Rockwell manuals all I can do is replace the cards!! That would be 4 cards in all at the moment. What I am doing to get out of the situation is reseating all the cards and hey presto I am back in action.
Now the puzzling thing about this is that 3 of the ENET cards are on one network with its own switch. The 4th card is on a seperate switch and is in no way connected to the other switch. The only thing that all the cards have in common is that they are all Series A cards.
I would like to think that there is a problem with Series A cards so that I could just replace them but I have about other 6 ENET Series A cards that are ok. No problems with my Series B cards.
Any ideas out there folks?
