Overview

The CM 1243-5 communication module is used to connect a

SIMATIC S7-1200 to PROFIBUS as a DP master and has the

following characteristics:

• PROFIBUS DPV1 master in accordance with IEC 61158

• Support of up to 16 PROFIBUS DP slaves

• Communication with other S7 controllers based on S7 commu-

nication

• Allows the connection of programming devices and operator

panels with a PROFIBUS interface to the S7-1200

• Module replacement without PG supported

• Support of all standard baud rates from 9.6 Kbit/s to 12 Mbit/s

• Compact industry-standard enclosure in S7-1200 design for

mounting on a standard mounting rail

• Fast commissioning thanks to easy configuration using

STEP 7 without additional programming overhead

The CM 1243-5 is intended for use in factory automation. Low-

cost PROFIBUS-based automation solutions can be created on

the basis of the S7-1200 for optimal production.
