Benefits

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.

Application

The CM 1243-5 is designed for use in factory automation, particularly for mechanical engineering

With the CM 1243-5, low-cost, distributed automation solutions can be implemented on the basis of the S7-1200 , or in simple cases even complete plant automation systems. It can be used in all sectors of discrete automation. These include, for example:

  • Automotive
  • Pharmaceuticals
  • Semiconductors
  • Food processing industry

In mechanical engineering, the S7-1200 can be used with the CM 1243-5 as a central control unit, with sensors, actuators or the HMI devices connected direct via PROFIBUS.

  • Pick-and-place machines
  • Metalworking machines
  • Packaging machinery
  • Printing machines
  • Textile machines
  • Filling machines
Design

The CM 1243-5 offers all the benefits of the S7-1200 design.

  • Rugged, compact plastic enclosure
  • Easily accessible connection and diagnostics elements, protected by front flaps
  • Removable connecting terminals
  • Simple mounting on the mounting rail of the S7-1200
  • 9-pin sub-D socket for the bus interface to PROFIBUS
  • 3-pin plug-in terminal strip for connection of the 24 V DC external supply voltage

The CM 1243-5 is plugged into the left-hand system bus interface of the S7-1200. The power is supplied via a 3-pin terminal strip on top of the module. The rugged RS485 interface is located on the underside of the module, protected by the lower front flap.

Function

The CM 1243-5 provides access to different communication services on the basis of PROFIBUS:

  • PROFIBUS DP (according to IEC 61158, master)
  • PG/OP communication
  • S7 communication

PROFIBUS DP master

The CM 1243-5 works as a DP-V1 master in accordance with IEC 61158, handles data traffic completely autonomously, and thus relieves the CPU of communication tasks.

The data areas of the distributed I/Os are transferred consistently between CP and CPU. As a DP master, it allows the connection of up to 16 PROFIBUS-compliant DP slaves

PG/OP communication

The S7-1200 to which the CM 1243-5 is connected can be programmed with the help of PG/OP communication.

S7 communication

Communication with the following other systems can be implemented with the mechanisms familiar from the S7 world (Put/Get) on the basis of S7 communication:

  • To other SIMATIC S7 programmable controllers
  • To HMI devices
  • To PCs, laptops, field PGs with PROFIBUS cards

Diagnosis

Extensive diagnostic options are available via STEP 7, including

  • Operating state of the CM
  • General diagnostics and statistics functions
  • Connection diagnostics
  • Message buffer

STEP 7 Basic V11 or higher is required for configuring the full functional scope of the CP 1243-5.
