Controller application area extended

The AS-i master CM1243-2 communication module of the Siemens Industry Automation Division connects AS-Interface networks to the Simatic S7-1200 controller. The module significantly expands the application area of the controller. The AS-i master enables sensors and actuators to be easily and quickly integrated at the lowest field level both in the Simatic S7-1200 and in the TIA Portal. Configuration via the TIA Portal is comparably fast and user-friendly, similar to Profinet or Profibus networks.

The AS-i master CM1243-2 of the Siemens Industry Automation Division offers exceptionally easy and effective connection of the lowest field level to a higher-level controller and thus to the process level and MES level. The new AS-i master automatically organizes the data traffic on the connected line, handles not only signal scanning but also performs parameter setting, monitoring and diagnostic functions. CM1243-2 also offers additional integrated functions, such as the configuration of Sirius M200D AS-i motor starters without additional function blocks and access via a web interface. A total of 62 AS-i slaves or 992 inputs and outputs to an AS-i master can be connected. A standard power supply can be connected via the optional DCM 1271 data coupling module, enabling the realization of a low-cost AS-i Power24V network.


Configuration and commissioning of the AS-i master is especially easy to perform due to the integration of the new device in the TIA Portal. AS-i engineering is performed directly in the TIA Portal and is similar to configuration with 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. The user can conveniently adapt the parameters of the slaves on screen.
