Posted 31 Mar 2015 Currently we have a remote I/O module to connect with our PLC, yet it's not showing up whenever we try to connect it via inside RS logix 5000. Share this post Link to post Share on other sites
Posted 1 Apr 2015 The quality of the answer is directly proportional to the quality of the information provided.... What PLC? What network/fieldbus? What module? What have you tried? Share this post Link to post Share on other sites
Posted 6 Apr 2015 PLC- Compact Logix Network- Ethernet Module- 1756-RIO but there is an RIO Red constant light, and a CLX flashing red light. Share this post Link to post Share on other sites
Posted 6 Apr 2015 The module won't show up automatically. You have to add it to the hardware configuration in RS Logix 5000. Right-click on the backplane and select new module. Share this post Link to post Share on other sites
Posted 6 Apr 2015 Wait... why are you trying to use a 1756-RIO with a CompactLogix in the first place ? You cannot just post "there is a flashing red light" when there are multiple indicator LEDs on the device. Why should I spend my time trying to guess which LED you mean ? Post details, and you can get some help. Share this post Link to post Share on other sites
Posted 6 Apr 2015 Thanks Ken, didn't even notice the part discrepancy. I suspect the OP means a ControlLogix. But back to my original point. The forum is like computers... Garbage In, Garbage Out Share this post Link to post Share on other sites
Posted 6 Apr 2015 I think that you can make an EtherNet/IP connection from a CompactLogix to a 1756-ENBT/EN2T and then to a 1756-RIO. It's the sort of thing I would expect from a user attempting to shoehorn a CompactLogix into an application that is more appropriate for a ControlLogix so they can save some money on hardware. But I don't know what the red flashing light on the CompactLogix is. Broken I/O connections usually just result in a blinking green Network Status LED, though if you configure a connection failure to fault the CPU that might generate a flashing red OK LED. If the OP comes back with usable information, we might be able to help. I did a big 1756-RIO application four years ago and was one of the first users in my area to use it for more than demos.

Posted 7 Apr 2015 I've only used the DHRIO card. It was right around the time the RIO card came out. We had problems with the speed of the network, so much so that I think the integrator I was working for went back and put in the RIO card once it was available.
