TozoM8 Posted July 23, 2020 Report Share Posted July 23, 2020 We are duplicating a machine. V1210 with V200-18-E3XB and EX-D16A3-TO16 just like the old one that works perfectly. Running into input problems. Input is on as it should and it does not change in live mode. Like I trip a breaker but it does not change status on plc. If I trigger another input that works. What gives? Link to comment Share on other sites More sharing options...
TozoM8 Posted July 23, 2020 Author Report Share Posted July 23, 2020 A pin on the back of the 1210 was bent so the snap on module did not connect properly. Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted July 23, 2020 MVP 2023 Report Share Posted July 23, 2020 Those Snap-In module connections can be a bear. Thanks for getting back with the solution. Link to comment Share on other sites More sharing options...
MVP 2023 Ausman Posted July 23, 2020 MVP 2023 Report Share Posted July 23, 2020 Don't forget the tip on holding the snap-in in place a lot better by using some carefully cut and applied "gaffer" tape. Link to comment Share on other sites More sharing options...
John_R Posted July 24, 2020 Report Share Posted July 24, 2020 As I've mentioned somewhere here before, I've taken to the habit of drilling holes in the corners of the snap-in modules (I've made a little drilling template that lays over the module), and securing with screws. For a few years now, the creators have provided screw bosses on the PLC case, but they still don't put the holes in the modules? this doesn't prevent someone from bending a pin, but it sure keeps the snap-in module from falling off due to machine vibration....

MVP 2023 Ausman Posted July 24, 2020 MVP 2023 Report Share Posted July 24, 2020 John, what's wrong with tape? Jeesh...even way in the future Sigourney still uses it to attach various gizmos onto her "kill all the aliens" weapon! I always laughed at that. 👽 Yes...screws are good. cheers, Aus Link to comment Share on other sites More sharing options...
John_R Posted July 28, 2020 Report Share Posted July 28, 2020 I don't know, even though I grew up around a farming community, I was never keen on baling wire and duct tape repairs 🥴 Link to comment Share on other sites More sharing options...
