RS-232 C Serial Interface, 9600 baud, 5 bytes
The interface integrated in the I/O module allows the connection of any device which is equipped with an RS-232 C interface.
The interface operates in accordance with the TIA/EIA-F, CCITT V.28/DIN 66259-1 standard.
The connected device can communicate directly with the control unit via the fieldbus coupler. The active communication channel works independently of the higher-level fieldbus system and allows full duplex operation up to 19200 baud.
The RS-232 C interface guarantees high interference immunity because of the electrically isolated signals.
The shield (screen) is directly connected to the DIN rail.
