Expanded controller applications with AS-i communications

Siemens expands applications for Simatic S7-1200 with new AS-I master communication module.


Siemens SIMATIC S7-1200Siemens Industry, Inc. significantly expands the application reach of the Simatic S7-1200 controller at both the lowest process instrumentation as well as MES Levels.  The introduction of the AS-i master CM1243-2 communication module enables field sensors and actuators to be quickly connected via the AS-Interface network to Siemens Simatic S7-1200 controller.

With a capability of connecting 62 AS-i slaves or 992 inputs and outputs, the AS-i master communication module automatically organizes data traffic on a connected line. It also is ideal for signal scanning, parameter setting, monitoring and diagnostic functions.  Integrated functions include Sirius M200D AS-i motor starter configuration without additional function blocks and access via a web interface.

Configuration and commissioning the AS-i master is simple with Siemens TIA Portal software. AS-i engineering is performed directly in the TIA Portal and is similar to configuring Profibus and Profinet. No additional software is required. The TIA Portal shows the topology of the connected AS-i network with a click of the mouse. Operators can also adapt the parameters of the slaves on screen.

A standard power supply can be connected via an optional DCM 1271 data coupling module for an affordable AS-i Power24V network.
