Design and Function
SIMATIC S7-1200 CPUs
The SIMATIC S7-1200 system has three different modules, the CPU 1211C, CPU 1212C and CPU 1214C. Each of these modules can be expanded 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. Signal modules can be connected to the right side of the CPU to further expand the digital or analog I/O capacity. 2 signal modules can be connected to the CPU 1212C and 8 signal modules can be connected to the CPU 1214C. Finally, up to 3 communication modules can be connected to the left side of all SIMATIC S7-1200 CPU controllers, facilitating end-to-end serial communication.
Simple and convenient installation
All SIMATIC S7-1200 hardware has built-in snaps for easy and convenient mounting on standard 35 mm DIN rails. These built-in snaps can also snap into an extended position, providing mounting holes when a panel is required. The SIMATIC S7-1200 hardware can be installed in a horizontal or vertical position, giving you other installation options. These integrated functions provide users with greater flexibility during installation and make the SIMATIC S7-1200 a practical solution for a variety of applications. .
space saving design
All SIMATIC S7-1200 hardware has been specially designed to save space on the control panel. For example, the CPU 1214C was measured to be only 110 mm wide, and the CPU 1212C and CPU 1211C were only 90 mm wide. Combined with the small footprint of the communication and signal modules, this modular, compact system saves valuable space during installation, giving you high efficiency and flexibility.
Modular concept for scalable compact automation
The SIMATIC S7-1200 features an integrated PROFINET interface, powerful integrated technology functions and a highly scalable and flexible design. It enables easy communication, efficient solution of technical tasks and fully meets a range of independent automation needs.
Larger CPUs can connect up to eight signal modules to support additional digital and analog I/O.
A single 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 offered by the SIMATIC S7-1200 allows you to design a controller system to exactly meet the needs of your application.
Provides up to 50 KB of integrated working memory for floating boundaries between user programs and user data. Provides up to 2 MB of integrated load memory and 2 KB of integrated memory at the same time. An optional SIMATIC memory card can easily transfer programs for use with multiple CPUs. The memory card can also be used to store other files or to update the controller system firmware.
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 an RJ45 connector with automatic error correction and provides a data transfer rate of 10/100 Mbit/s. It supports up to 16 Ethernet connections and the following protocols: TCP/IP native, ISO on TCP and S7 communication.
With its integrated technology for calculations and measurements, closed-loop control and motion control, the SIMATIC S7-1200 is a very powerful system for many types of automation tasks.
The SIMATIC S7-1200 controller integrates two high-speed outputs that can be used as pulse train outputs or outputs for tuned pulse widths. When configured as a PTO, provides a 50% duty cycle pulse train at speeds up to 100 kHz for open loop speed and position control of stepper motors and servo drives. Feedback to the pulse train output is provided internally using two of the high-speed counters. When configured as a PWM output, a fixed-cycle output with a variable duty cycle is provided to control the speed of a motor, the position of a valve, or the duty cycle of a heat generating component.
The SIMATIC S7-1200 supports open loop speed and position control of stepper motors and servo drives. This function can be easily configured in engineering SIMATIC STEP 7 Basic using the axis technology objects and the internationally recognized PLCopen motion function blocks. In addition to the "home" and "jog" functions, absolute movement, relative movement and velocity movement are also supported.
Engineering The drive commissioning control panel included in SIMATIC STEP 7 Basic simplifies the start-up and commissioning of stepper motors and servo drives.
It provides automatic and manual control of individual motion axes, as well as online diagnostic information.
The SIMATIC S7-1200 supports up to 16 PID control loops for simple process control applications. These control loops can be easily configured with the aid of the PID controller technology object and the supporting editor provided in SIMATIC STEP 7 Basic for engineering. In addition, the SIMATIC S7-1200 supports the PID auto-tuning function, which automatically calculates the best tuning values for saving time, integration time and derivative time.
The PID commissioning control panel included in SIMATIC STEP 7 Basic simplifies the loop tuning process. It provides automatic tuning and manual control for a single control loop, while providing a graphical trend view of the tuning process.
