I’m not sure how familiar most of you are with Wago remote I/O, but I hope you may have some solution for the following connection problem I’m having.
I’m working on a project to modernise an old folder collecting machine for which I’m using an Omron CJ2M Cpu33 together with 8 Wago 750-352 remote I/O units over ethernet/ip.
These Wago units all contain two 8DI digital input cards and two 8DO digital output cards alongside a 750-610 bus power supply card.
Adding them to my network in CX network manager is no problem and all seems to work fine. That is, as long as I don’t physically add the bus power supply card, which I need to, well.. power the Wago bus.
Soon as I add this card (which was in place while making all the necessary settings to the Wago and Omron units) it just won’t connect. Remove it and it connects like it should.
As far as I know the power supply card has no I/O addresses or other communication functions whatsoever, so I can’t get my head around it.
Even stranger is that when instead of it I add an analog input card, with bus power connections build in, it connects without a problem.
The .eds file only contains info about the main Wago unit, after installing it I should be able to add any kind of I/O card and address them in the Omron software.
Also, the supply card is added and visible as a fifth card in the Wago I/O settings and the I/O status led is green during this error. Therefore I would say the problem is at the Omron side.
Thanks in advance
