SIEMENS S7-1200 SIPLUS CM 1243-5 communication modules

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.

SIPLUS S7-1200 CM 1243-5; -25 … +55 DEGREES C WITH CONFORMAL COATING BASED ON 6GK7243-5DX30-0XE0 . COMMUNICATION MODULE CM 1243-5, TO THE CONNECTION OFF S7-1200 TO PROFIBUS AS A DP MASTER ASSEMBLY

PROFIBUS-based systems can be operated effectively for lower operating and maintenance costs:

  • Low costs since an automation solution requires no fixed wiring and less hardware
  • Fast response to faults thanks to excellent diagnostics options
  • Optimized plant and inventory management

The CM 1243-5 also offers further benefits especially for the requirements of micro-automation solutions:

  • Uncomplicated connection of the S7-1200 to PROFIBUS
  • Low-cost implementation of automation solutions based on PROFIBUS
  • Fast commissioning, as no programming overhead is required

Use of PROFIBUS-based micro-automation solutions enables optimal operation of the plant and problem-free production.
