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 communication
• 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.
