ABB Sattline

Can any tell me how to interface Allen Bradley PLC with ABB Sattline system.

I don’t know Allen Bradley but I guess the easiest way is to use profibus DP. But remember sattline can only act as master.
Another possible approach is to use some kind of gateway to exchange information between the two systems using sattline’s comli protocol and Allen Bradley’s serial interface.
I don’t know of a supplier of such device but I pretty sure some can.
A third option is to make use of OPC servers and link them together in a computer application of some sort.

Seen from the sattline side these possible options then again relay on which system release level you are using.
