Design and function

SIMATIC S7-1200 CPU

SIMATIC s7-1200 system has three different modules: CPU 1211c, CPU 1212c and CPU 1214c. Each of these modules can be extended to fully meet your system needs. A signal board can be added in front of any CPU to easily expand digital or analog i/o without affecting the actual size of the controller. The signal module can be connected to the right side of the CPU to further expand the digital or analog i/o capacity. CPU 1212c can connect 2 signal modules, and CPU 1214c can connect 8 signal modules. Finally, up to three communication modules can be connected to the left side of all SIMATIC s7-1200 CPU controllers to facilitate end-to-end serial communication.

Simple and convenient installation

All SIMATIC s7-1200 hardware has built-in snap, which can be easily installed on the standard 35 mm DIN rail. These built-in snaps can also be clamped into the expanded position, and mounting holes can be provided when the panel needs to be installed. SIMATIC s7-1200 hardware can be installed in a horizontal or vertical position, providing you with other installation options. These integrated functions provide users with the greatest flexibility in the installation process, and make SIMATIC s7-1200 provide practical solutions for various applications

Space saving design

All SIMATIC s7-1200 hardware is specially designed to save space on the control panel. For example, after measurement, the width of CPU 1214c is only 110 mm, and the width of CPU 1212c and CPU 1211c is only 90 mm. Combined with the small space occupied by the communication module and the signal module, the modular compact system saves valuable space during installation and provides you with the highest efficiency and flexibility.

Highlights

Highly scalable and flexible design

Signal module:

The largest CPU can connect up to eight signal modules to support other digital and analog i/o.

Signal board:

A signal board can be connected to all CPUs, allowing you to customize the CPU by adding digital or analog i/o to the controller without affecting its actual size. The modular concept provided by SIMATIC s7-1200 allows you to design the controller system to fully meet the needs of your application.

Memory

Provide up to 50 KB of integrated working memory for the floating boundary between user programs and user data. Up to 2 Mb of integrated load memory and 2 kb of integrated memory memory are provided at the same time. The optional SIMATIC memory card can easily transfer programs for use by multiple CPUs. The memory card can also be used to store other files or update the firmware of the controller system.

Integrated PROFINET interface

The integrated PROFINET interface is used for programming and HMI and PLC to PLC communication. In addition, the interface supports third-party devices using the open Ethernet protocol. The interface has RJ45 connector with automatic error correction function, and provides a data transmission rate of 10/100 megabits / second. It supports up to 16 Ethernet connections and the following protocols: tcp/ip native, ISO on TCP and S7 communication.

SIMATIC s7-1200 integrated technology

SIMATIC s7-1200 has integrated technology for calculation and measurement, closed-loop control and motion control. It is a very powerful system that can realize various types of automatic tasks.

High speed output for speed, position or duty cycle control

SIMATIC s7-1200 controller integrates two high-speed outputs, which can be used as output of pulse sequence or output of tuning pulse width. When configured as a PTO, it provides a 50% duty cycle pulse sequence at a speed of up to 100 kHz, which is used to control the open-loop speed and position of the stepper motor and servo driver. Two of the high-speed counters are used to internally provide feedback on the pulse sequence output. When configured as a PWM output, a fixed number of cycles output with variable duty cycle will be provided to control the speed of the motor, the position of the valve or the duty cycle of the heating component.

PLCopen motion function block

SIMATIC s7-1200 supports the control of open-loop speed and position of stepping motor and servo driver. Using the axis technology object and the internationally recognized PLCopen motion function block, this function can be easily configured in the engineering configuration simple step 7 basic. In addition to the "home" and "jog" functions, it also supports absolute movement, relative movement and speed movement.

Drive commissioning control panel

The drive debugging control panel attached to SIMATIC step 7 basic simplifies the startup and debugging operations of stepping motors and servo drives.

It provides automatic and manual control of a single motion axis, as well as online diagnostic information.

PID function for closed loop control

SIMATIC s7-1200 can support up to 16 PID control loops for simple process control applications. With the help of PID controller technical objects and the supporting editor provided in SIMATIC step 7 basic for engineering configuration, these control loops can be easily configured. In addition, SIMATIC s7-1200 supports PID automatic adjustment function, which can automatically calculate the best adjustment value for saving time, integral time and differential time.

PID commissioning control panel

The PID debugging control panel attached to SIMATIC step 7 basic simplifies the loop adjustment process. It provides automatic adjustment and manual control functions for a single control loop, and provides a graphical trend view for the adjustment process.
