AS-Interface Master for SIMATIC S7-1200

Modular. Powerful. Easy Engineering.

With one AS-i master CM1243-2, up to 62 AS-i sensors and actuators or up to 992 I/O points can be connected to the SIMATIC S7-1200. A total of up to 3 AS-i masters can be used in an S7-1200 control. The AS-i networks' engineering is easily realized via drag & drop in the TIA Portal, comparable to PROFIBUS and PROFINET networks.

Integrated additional functions amongst others facilitate the parameterization of SIRIUS M200D motor starters via AS-i without additional function blocks in the user program. Moreover, the optional DCM 1271 data decoupling module supports the use of standard 24 V power supply units (AS-i Power24V).
