Integrated PROFINET Interface
The SIMATIC S7-1200 supports communication with PROFINET IO devices as a PROFINET IO controller. By means of the integrated Web-server, information can be called via the CPU and process data via a standard Web browser. Data can also be archived from the user program during runtime.
Utilizing established TCP/IP standards, the integrated PROFINET interface provided with the SIMATIC S7-1200 can be used for programming or to communicate with HMI devices and additional controllers. As a PROFINET IO controller, SIMATIC S7-1200 now supports communication with PROFINET IO devices and drives.
The interface consists of a noise-immune RJ45 connector with auto-cross-over functionality,
which supports Ethernet networks and features a data transmission rate of up to 10/100
Mbit/s.
New with firmware version 4.0 CPU’s Profinet iDevice:
Easiest configuration for S7-1200 CPU’s into a Controller / device architecture by reading & writing into each others IO image.
Communication with third-party devices
Seamless integration of devices from other manufacturers is possible with the integrated PROFINET 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.
This communication capability, which is configured with standard T-Send/T-Receive instructions provided by the integrated engineering system SIMATIC STEP 7 Basic, offers you an even higher level of flexibility in designing your automation solution.
New with firmware version 4.0 CPU’s now have more communications options:
Easy communication modules
Up to 3 communication modules can be added to any of the SIMATIC S7-1200 CPUs.
The RS485 and RS232 communication modules are fit for serial, character-based point-to-point connections. The library functions USS drive protocol and Modbus RTU Master and Slave protocols are already included within the SIMATIC STEP 7 Basic engineering system.
