[Translate to English:] Die "Sprachen" (Protokolle) führender SPS-Hersteller sind in Tixi Alarm Modems optional eingebaut.
Es brauchen keine Treiber oder Funktionsbausteine in die SPS geladen zu werden, damit Tixi Variablen oder I/O-Ports lesen und schreiben kann.
Wenn eine SPS über ein Tixi-Modem Störmeldungen versenden soll, dann fragt Tixi z.B. SPS-Variablen oder Eingänge direkt in der SPS ab und startet den Versand der Meldungen automatisch, ohne daß die SPS etwas tun muß.

The "languages" (protocols) of leading PLC manufacturers are integrated in Tixi Alarm Modems as required.
This enables Tixi to read and write variables or I/O ports without having to load drivers or functions blocks in the PLC.
If a PLC is required to send fault indication messages via a Tixi modem, Tixi scans the PLC variables or inputs in the PLC and initiates the sending of messages automatically, without the PLC having to do anything.

There are two options available if the protocol for the required PLC is not integrated:
- Tixi and the PLC use a fieldbus standard such as MODBUS, M-Bus or
- A Tixi protocol (TiXML, Tixi bus) is loaded into the PLC.
Further information on communication for the PLC and Tixi is provided in the TiXML and Tixi bus manuals.
