X22: Designs with PROFIBUS DP-V0 interface
Th e pin assignment of the design with PROFIBUS DP-V0 meets the
requirements of EN 50 170.
Additionally to the signals RxD/TxD+, RxD/TxD-, PB_GND and
PB_5V the optional signal CNTR (RTS, control of the forward direc-
tion of the data) is supported. Th is signal can be used for controlling
a repeater or an fi bre optic link converter (OLP, Optical Link Plug).
Th e bus interface of the ECOVARIO® is electrically seperated from
the rest of the device. But the reference potentials are interconnected
via 1 MΩ and 100 nF. Th e interface is supplied by the unit, an external supply in not necessary.
Th e shroud of the Sub-D connector is connected to chassis earth (GND).
