3.3.1 System design
An I/O system 1000 consists of the following modules:
ƒ An EPM−S1xx bus coupler module
– Connection of the aystem to a fieldbus system (CANopen, PROFIBUS, etc.)
– Integrated DC power supply unit for the supply of the bus coupler module and the
connected I/O compound modules via the backplane bus.
ƒ Up to 64 EPM−S2xx ... EPM−S6xx I/O compound modules (DI, DO, AI, AO, counter,
etc.)
