■
Overview
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 commu-
nication
•
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.
■
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.
