Siemens CM 1242-5 – 6GK7242-5DX30-0XE0

Overview

The CM 1242-5 communication module is used to connect a SIMATIC S7-1200 to PROFIBUS as a DP slave and has the following characteristics:

  • PROFIBUS DPV1 slave in accordance with IEC 61158
  • Module replacement without PG supported
  • Power is supplied via the backplane bus so that no extra cabling is required
  • Support of all standard baud rates from 9.6 kbps to 12 Mbps
  • Compact industry-standard enclosure in S7-1200 design for mounting on a DIN rail
  • Fast commissioning thanks to easy configuration using STEP 7 without additional programming overhead

The CM 1242-5 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.

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 comprehensive diagnostics options
  • Optimized plant and inventory management

The CM 1242-5 also offers further benefits especially for the requirements of micro-automation solutions:

  • Straightforward connection of the SIMATIC S7-1200 to PROFIBUS without an extra power supply
  • Low-cost implementation of automation solutions based on PROFIBUS
  • Fast commissioning, as no programming overhead is required

Application

The CM 1242-5 is designed for use in factory automation.

With the CM 1242-5, 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

Design

The CM 1242-5 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

The CM 1242-5 is plugged into the left-hand system bus interface of the S7-1200. Power is supplied via the system bus of the S7-1200 so that no extra cabling is required. The rugged RS485 interface is located on the underside of the module, protected by the lower front flap.

Function

The CM 1242-5 provides the communication services for integrating an S7-1200 into an automation solution as a PROFIBUS DP slave.

PROFIBUS DP slave

The CM 1242-5 works as a DPV1 slave 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.

Diagnosis

Extensive diagnostic options are available via STEP 7, including

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

STEP 7 Basic V11 or higher is required for configuring the full functional scope of the CP 1242-5.
