New AS-i Master Communications Module Expands Applications for SIMATIC® S7-1200

Siemens Industry, Inc., introduces the AS-I master CM1243-2 communications module, enabling field sensors and actuators to be quickly connected via the AS-Interface network to Siemens Simatic S7-1200 controller. This significantly expands the application reach of the Simatic S7-1200 at both the lowest process instrumentation and MES levels, providing a cost-effective and easy-to-configure distributed I/O network.

Use of this module will reduce installation costs significantly compared to hard-wired I/O. AS-Interface is an open Master-Slave, two-wire network supported by multiple vendors and provides both power and communication for 62 distributed devices up to 600 feet away. The ability to connect both standard and safe rated I/O on the same network further reduces costs and provides easy zone control shut down of a process or machine.

Capable 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 of the module include Sirius M200D AS-i motor starter configuration without additional function blocks and access via web interface.

Siemens TIA Portal software makes configuration and commissioning of the AS-i master a simple process. 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.

The AS-i master CM1243-2 communications module can be used in all industries requiring distributed I/O, particularly those that need to connect to both safe and standard I/O that reside on the same network without requiring a “Safe PLC.”
