SIMATICS S7-1200

SIMATIC S7-1200 small programmable controller fully meets the needs of small and medium-sized automation system. The seamless integration and efficient coordination of system, controller, human-machine interface and software are fully considered in the development process. The advent of SIMATIC S7-1200 series indicates that Siemens has expanded the product layout on the basis of the original product series and represents the future development direction of small programmable controllers. Siemens will continue to pioneer and innovate, leading the trend of automation.
SIMATIC S7-1200
SIMATIC S7-1200 has the characteristics of integrated PROFINET interface, powerful integrated process function and flexible scalability. It provides simple communication and effective solutions for various process tasks, especially to meet completely different automation requirements in various applications.

communication module
SIMATIC S7-1200 CPU can add up to three communication modules to support PROFIBUS master-slave communication. RS485 and RS232 communication modules provide connection and I/O connection master for point-to-point serial communication.
Station. Expanded instruction or library function, USS driver protocol, Modbus RTU master station and slave station protocol are used in the configuration and programming of the communication. They are all included in the SIMATICSTE7 Basic engineering configuration system.

Simple Remote Control Application
The new communication processor CP 1242-7 can simultaneously monitor and control distributed S7-1200 units through simple HUB (hub) or mobile phone network or Internet (Internet).

Integrated PROFINET Interface
The integrated PROFINET interface is used for programming, HMI communication and PLC communication. In addition, it supports communication with third-party devices through an open Ethernet protocol. The interface has a RJ45 connector with auto-cross-over function, which provides 10/100 Mbit/s data transmission rate and supports the following protocols: TCP/IP native, ISO-on-TCP and S7 communication.
The maximum number of connections is 23
Three connections for communication between HMI and CPU
A connection for communication between programming device (PG) and CPU
Eight connections are used for programming communication of Open IE (TCP, ISO-on-TCP) using T-block instructions. They can be used for communication between S7-1200 and between S7-1200 and S7-300/400.
Three server-side connections for S7 communication can achieve S7 communication with S7-200, S7-300/400 ethernet.
Eight client connections for S7 communication, which can communicate with S7-200, S7-300/400 Ethernet S7

S7-1200 small programmable controller fully meets the needs of small and medium-sized automation system. The seamless integration and efficient coordination of system, controller, human-machine interface and software are fully considered in the development process. SIMATIC S7-1200 integrates PROFINET interface, which makes the programming, deb ing process and the communication between controller and human-machine interface possible to use PROFINET Industrial Ethernet technology in an all-round way, and provides good support for the upgrading of existing PROFIBUS system.
The design of S7-1200 miniature controller has expansibility and flexibility, so that it can accurately fulfill the complex requirements of automation tasks on the controller. CPU ontology can be flexibly extended by embedding input/output signal boards. "Signal board" is one of the highlights of S7-1200. The signal board embedded in the front end of CPU module can provide two digital input/digital output interfaces or an analog output. This feature makes the system design compact and configuration flexible. At the same time, S7-1200 communication can be flexibly extended by independent RS-232 or RS-485 communication module.
The advent of SIMATIC S7-1200 series indicates that Siemens has expanded the product layout on the basis of the original product series and represents the future development direction of small programmable controllers. Siemens will continue to pioneer and innovate, leading the trend of automation.
