The connection to the Profibus-DP is established via a 9-pin D-SUB socket.
Up to 62 I/O modules can be connected per bus coupler. The modules are connected via an internal bus system. Up to 16 modules can be operated directly at the bus coupler, furthermore the system can be extended by an additional power module – HE 5850.
In the bus coupler, the areas of supply voltage, fieldbus and logic are galvanically isolated from each other. The system configuration consisting of bus coupler and I/O modules can be quickly determined via the button integrated in the front of the housing. Configuration and parameterization of the individual modules can be done via the fieldbus as well as via the SmartPort interface.
