No. There's two different types of I/O modules available - "Snap-In" modules and "Expansion" modules. Depending on your project requirements, you can have either or both. Sometimes the Snap-In modules can work lose and cause problems, so that is why I was asking.

The project contain 3 IO modules Digital, and I already tested the expansion cable. But the fails still happening

No, I don't. It's necessary install this Module?

Not yet... This cable is a common ethernet cable ? Or need to replace for a orginal expansion cable ?

Hi,

Would someone help me with this fail? This occurs suddenly when the machine is running.
