IO-Link Master Module for S7-1200
SM 1278 4xIO-Link master

■
Overview
SM 1278 4xIO-Link master
Module for connecting up to four IO-Link devices in accordance
with the IO Link specification V1.1. The IO-Link parameters are
configured by means of the Port Configuration Tool (PCT) with
version V3.2 and higher.
■
Application
The SM 1278 module enables an exchange of data with up to
four external IO Link devices through one three-wire cable each
or four standard actuators or standard encoders. Control can be
flexibly adapted to the communication partners using the com-
prehensive parameter assignment options. Since IO-Link is
compatible with standard sensors, commercially available
sensors compliant with IEC 61131 Type 1 can also be operated
on the IO-Link master.
