Description
The bus coupler is the link between a PROFINET network and the Inline installation system. In addition, it is used to acquire and output digital signals.
Up to 61 Inline devices can be connected at any point to an existing PROFINET network using the bus coupler.
The bus coupler and the Inline devices form one station with a maximum of 63 local bus devices. Here, the inputs and outputs of the bus coupler form the first and second local bus devices.
