3.5.2 PROFIBUS − EPM−S120
The bus coupler module represents the interface between the process level (I/O level) and
the higher−level fieldbus. The control signals on the process level are transmitted by the I/O
compound modules via the internal backplane bus.
Features
ƒ PROFIBUS−DP slave; supports PROFIBUS−DP−V1
ƒ Up to 64 I/O compound modules can be connected to a PROFIBUS bus coupler
module
ƒ Integrated power supply unit for the internal voltage supply and the voltage supply
of the connected I/O compound modules
– Power supply unit is fed via an external DC voltage source
ƒ Connection to the PROFIBUS via 9−pin Sub−D socket
ƒ Coding switch for setting the PROFIBUS address
ƒ LEDs for status display
