Is the working area of the PLC insulated from the cabinet itself?

I checked our supplier’s unit – there are two grounding bars inside the cabinet, one of which is insulated from the cabinet itself. Why is that?

It’s hard to say without a diagram; I guess it might be that the grounding bar is insulated from the cabinet body! If that’s the case, it’s normal; that’s what the regulations require
