dugtries Posted October 7, 2022 Report Share Posted October 7, 2022 Hello everyone, Does anyone have any idea why the snap on i/o module is not being pick up on the plc? Its a v1210 hmi/plc and a v200-18-E3XB i/o module. Quote Link to comment Share on other sites More sharing options...
MVP 2021 kratmel Posted October 7, 2022 MVP 2021 Report Share Posted October 7, 2022 Hi, is it Snap-IN selected in Hardware config? Quote Link to comment Share on other sites More sharing options...
dugtries Posted October 7, 2022 Author Report Share Posted October 7, 2022 @kratmel Yes, I did select the snap-in i/o you show and clicked ok. Quote Link to comment Share on other sites More sharing options...
MVP 2021 kratmel Posted October 7, 2022 MVP 2021 Report Share Posted October 7, 2022 And you downloaded project with this selection? Quote Link to comment Share on other sites More sharing options...
Gabriel Franco Posted October 7, 2022 Report Share Posted October 7, 2022 In addition to Kratmel comments, make sure the snap is properly seated on the back. Quote Link to comment Share on other sites More sharing options...
MVP 2021 Ausman Posted October 7, 2022 MVP 2021 Report Share Posted October 7, 2022 I enlarged the snapin image and it's hard to tell, but make sure the 0V & V1 connections are in the end of the connector, not 1 location inwards. The alignment in the photo shows 5N1 and BP1 into 0V & V2 looking correct, but the same lines into 0V & V1 look the same visual alignment but this means that they are one terminal upwards. If you could redo pics of the an input and an outputs from the side which will show the exact cable insertions that might help checking. I'm assuming 5N1 is 0V. It also appears that you're running them from separate supplies. This can cause issues. On Gabriel's suggestion, there are many references on the forum to snap-in tricks and fixes. The main one being that they have little room for error in mounting, and need to be fully in and retained that way. Some people add screws where you can, I use gaffer tape. cheers, Aus Quote Link to comment Share on other sites More sharing options...

I'm one of those people who have added screws to hold the snap-I/O in place, Unitronics added screw bosses to the PLC's years back, but the never did include screw holes in the snap-I/O modules. I made up a drill template to accurately place four holes in the corners of the snap-I/O modules, which resolved loose module issues in our high vibration machines.

dugtries Posted October 11, 2022 Author Report Share Posted October 11, 2022 Hello everyone, Thanks for the help. The problem was not the io module. When snap in we notice the pins were not fully inserted and it was loose. I removed the back cover of the HMI and placed the io module fully inserted and now the io module is communicating with the plc. Wish I found this problem earlier.

John_R Posted October 12, 2022 Report Share Posted October 12, 2022 Again, a good reason to properly secure the Snap I/O to the PLC, as I've mentioned many times in the past. Unitronics provided screw bosses on the PLC's a few years back, but never provided screw holes in the Snap I/O modules... Do yourself a favor and make the needed holes to screw it down, or use gaffers tape , or zip ties.. something to hold the module firmly in place... Note the totally unintentional reference to Joe T in the picture...😉 1 Quote Link to comment Share on other sites More sharing options...
