SAS 341-1

1 x RS422/RS485

The SAS 341-1 is a serial communication module for use in S7-300* systems.

It allows the connection to the PLC of serial devices such as barcode scanners, operator terminals, serial printers, PCs, PLCs of other manufacturers and supports the protocols ASCII and 3964R and RK512.
The SAS 341 features advanced functions such as support for higher baud rates up to 115 kBaud, making it flexible without any loss of compatibility.
The linking of different PLC types of the S7-300* is flexibly implemented using the standardized RK512 computer link protocol.
The handling blocks supplied enable simple and flexible integration into the PLC. The module is parameterized in the hardware configurator of the PLC.

The serial units are connected via RS422/RS485. The 15-pin Sub-D socket with standard pin assignment is provided for connecting the partner devices.
A virtual COM port driver enables the use of software that expects a COM interface.
