Use
The interfaces are designed for operation in full-duplex mode; in other words, the ports can
be used for the sending as well as for the receiving of data packets. The ports are connected
as an Ethernet terminal with 10/100 Mbit:
● X130 connects the PPU to the plant network.
– The IP address can be freely selected.
– MAC address, see also: Type plate (Page 25).
● X127 is used to connect the following components:
– PG/PC via peer-to-peer with permanently assigned IP address 192,168,215 .1, for
example, for the commissioning software, RCS Commander
– Modem for remote diagnostics
