Fast, easy and flexible industrial communication

Integrated PROFINET Interface
The new SIMATIC S7-1200 is equipped with an integrated PROFINET interface which provides seamless communication with the integrated engineering system for programming, with HMI panels for visualization, with additional controllers for PLC-to-PLC communication and with third-party devices for advanced integration possibilities

SIMATIC S7-1200 Communication


Simple Networking

The SIMATIC S7-1200 communication interface consists of a noise-immune RJ45 connector with auto-cross-over functionality supporting up to 16 Ethernet connections and providing data transmission rates up to 10/100 Mbit/s. To minimize cabling and provide maximum networking flexibility, the new CSM 1277 Compact Switch Module can be used together with the SIMATIC S7-1200 to easily configure a uniform or mixed network consisting of line, tree or star topologies. The CSM 1277 is a 4-port unmanaged switch which allows you to connect the SIMATIC S7-1200 with up to 3 additional devices. Additionally, using the SIMATIC S7-1200 in combination with SIMATIC NET Industrial Wireless LAN components you are provided with a completely new dimension in networking possibilities.

Communication with additional controllers and HMI devices
To ensure communication with additional SIMATIC controllers and HMI devices, the SIMATIC S7-1200 supports the connection to multiple S7 controllers and HMI devices communicating together with the proven S7-Communication protocol.

Communication Modules
Up to 3 Communication Modules can be added to any of the SIMATIC S7-1200 CPUs. The RS485 and RS232 Communication Modules provide the connection for performing Point-to-Point serial communication. This communication is configured and programmed using extended instructions or with the library functions, USS drive protocol and Modbus RTU Master and Slave protocols, which are included within the STEP 7 Basic engineering system.

Communication with third-party devices
Seamless integration of devices from other manufacturers is possible with the integrated interface on the SIMATIC S7-1200. It is possible to connect and communicate with multiple third-party devices utilizing the supported open Ethernet protocols TCP/IP native and ISO on TCP. Configured with the standard T-Send / T-Receive instructions provided by the integrated engineering system SIMATIC STEP 7 Basic, this capability offers you an even higher level of flexibility in designing your automation solution.
