verview

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 programming devices and operator panels with PROFIBUS interfaces to be connected to the SIMATIC S7-1200

Module replacement without PG supported

Support of all standard baud rates from 9.6 kbps to 12 Mbps

Compact industrial enclosure in SIMATIC 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 SIMATIC S7-1200 for optimal 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 SIMATIC 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 SIMATIC 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

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
