2.1.1.3 Description

This interface allows the connection of any device which is equipped with a
RS 232 C serial interface.

The wiring to the communication partner is made by the connections TxD,
RxD, if necessary RTS and CTS as well as ground (earth).
The shield (screen) is directly connected to the carrier rail.

The interface works in accordance with the TIA/EIA-232-F, CCITT V.28/DIN
66259-1 standard.
The connected device may directly communicate over the fieldbus coupler/­controller with the control unit. The active communication channel works
independently of the higher-level fieldbus system and allows full duplex
operation up to 19200 baud.

Three green LEDs signal readiness for operation and troublefree internal bus
communication as well as the condition of the signal transmission.

The RS 232 interface guarantees high interference immunity because of the
electrically isolated signals.

Any configuration of the specialty modules is possible when designing the
fieldbus node. Grouping of module types is not necessary.
