		CP 343-2	6GK7 343-2AH00-0XA0
		Communications processor for
		connection of SIMATIC S7-300
		and ET 200M to AS-Interface,
		without front connector

The actuator-sensor interface (AS-Interface) is a multi-vendor networking system for simple - usually binary - actuators and sensors in the lowest field area. AS-Interface enables a wiring loom with parallel wiring to be replaced by a simple two-wire ca- ble shared by all sensors or actuators.

The AS-Interface works by the master-slave principle. Sensors/ actuators connected through the AS-Interface cable are con- trolled by the master as slaves.

Note:

AS-Interface is integrated in SIMATIC pcs 7 as a subordinate bus. Consequently, this bus does not offer the full functionality of SIMATIC PCS 7; this applies in particular to diagnostics func- tions. Further information, see Catalog IK PI.

System components

The basic components of a system installation are:

•CP 343-2 AS-Interface master module for ET 200M or/and DP/AS-Interface link for connection of an AS-Interface line to

PROFIBUS DP

•AS-Interface shaped cable (use of round cable also possible if preferred)

•Modules for connecting standard sensors/actuators

•Power supply unit for powering the slaves

•Actuators and sensors with an integrated slave ASIC

•Address programming device for setting the slave address
