Personally, I'm not a fan of Wago/Beckhoff. After working with them for a few years, I've found them not to be very reliable and have caused me numerous headaches trying to troubleshoot them. What tends to happen is the bus connectors on each slice tend to corrode over time. It doesn't take much for this corrosion to interrupt communications and fault out the entire rack, randomly taking your system down.
The comm adapters also supposedly give you a flash code to tell you which module is bad, but I don't think I've ever had that code actually be accurate in telling me which module actually was bad. It'll usually be two or three slices off. So it'll flash six times and card 3 is actually the problem.
At my last job where I ran into this a lot we actually implemented a PO for maintenance to go around the plant to pull out and re-seat every single beckhoff/wago card in the facility every few months. Otherwise, between the corrosion, heat, and vibration, we'd be plagued with mysterious machine shutdowns with no obvious cause.
I'd only use them if you can't find any other solution. But if you can avoid them, do so. They're a maintenance nightmare.
I've found the exact opposite... We have a lot in a wwtp that had a bad h2s problem.. Everything died except the beckhoff. Never had a bus issue, excepting 1 block that had a pneumatic solenoid rack attached which needed a beefier din rail to keep it all lined up..
