The interface integrated in the I/O module allows the connection of any device
which is equipped with an RS-485 interface.
The interface operates in accordance with the TIA/EIA-485-A, DIN 66259
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-485 interface guarantees high interference immunity because of the
electrically isolated signals.
The shield (screen) is directly connected to the DIN rail.
