SAS 340-2

2 x RS232, 2 x USB

The SAS 340-2 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.
The SAS 340-2 features advanced functions such as support for higher baud rates up to 115 kBaud, making it flexible without any loss of compatibility.
The handling blocks supplied enable simple and flexible integration into the PLC. The module is parameterized in the hardware configurator of the PLC. The expanded functionalities can also easily be activated with the handling blocks.

The serial units are connected via RS232. The two 9-pin Sub-D sockets with standard pin assignment are provided for connecting the partner devices.
The additional USB device interface enables the connection of the PLC to PC systems, many of which no longer have a conventional physical port. A virtual COM port driver enables the use of software that expects a COM interface.
