Description
Signal modules
Signal Boards, Signal Modules
Signal boards can be added to the CPU to increase the number of digital or analog inputs and outputs, RS485 communication and battery board to the controller for your application requirements without increasing the controller‘s footprint.
Communication
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.
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.
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.
