The serial interface module connects RS-485/422 or RS-232 C interface
devices to the WAGO-I/O-SYSTEM 750. It also provides gateways between
the serial interface and the fieldbus systems supported by the
WAGO-I/O SYSTEM 750. No higher protocol level is required by the module.
Communication to the associated fieldbus master is completely transparent.
This provides for a broader application scope for the serial interface module.
If required, communication protocols can be configured via fieldbus master.
The 2560 byte input buffer provides for high data baud rates. At lower baud
rates, the data received in lower priority tasks is evaluated without data loss.
The 512 byte output buffer provides fast transmission of larger data strings.
The module can be configured via WAGO-I/O-CHECK or GSD files.
Flexible baud rate and data width selection provides perfect adaptation to the
respective application.
Compatibility with couplers/controllers:
