S7-1200 Design and functions

SIMATIC S7-1200 CPUs
The SIMATIC S7-1200 system comes in three different models, S7-1200 CPU 1211C, S7-1200 CPU 1212C and S7-1200 CPU 1214C, that may each be expanded to exactly fit your machine requirements. One signal board can be added inside the front of any CPU to easily expand the digital or analog I/Os without affecting the physical size of the controller. Signal modules can be connected to the right side of the S7-1200 CPU to further expand the digital or analog I/O capacity. S7-1200CPU 1212C accepts two and S7-1200 CPU 1214C accepts eight signal modules. Finally, all SIMATIC S7-1200 CPUs can be equipped with up to three communication modules on the left side of the controller for performing point-to-point serial communication.

Easy and convenient installation
All SIMATIC S7-1200 hardware has built-in clips that allow for easy and convenient mounting on a standard 35-mm DIN rail. These built-in clips can also be snapped into an extended position to provide mounting holes for situations where panel mounting is required. The SIMATIC S7-1200 hardware can be installed in either a horizontal or vertical position providing you with additional installation options. These integrated features offer users maximum flexibility during the installation process and they make the SIMATIC S7-1200 a practical solution for a wide variety of applications.

Space-saving design
All SIMATIC S7-1200 hardware has been specifically designed to save space in the control panel. For example, S7-1200 CPU 1214C has a width measuring only 110 mm and both the S7-1200 CPU 1212C and S7-1200 CPU 1211C are only 90 mm wide. Together with the small footprint of the communication modules and signal modules, this modular and compact system saves valuable space and offers you the highest level efficiency and flexibility during the installation process.

SIMATIC S7-1200
A modular concept for compact automation in a scalable design.
The SIMATIC S7-1200 features an integrated PROFINET interface, powerful integrated technology functions and a highly scalable and flexible design. This enables simple communication, efficient solutions for technological tasks, and perfectly fits individual automation requirements in a wide variety of applications.

Highlights
Scalable and flexible design
Signal Modules:
Up to eight signal modules can be connected to the largest S7-1200 CPUs for the support of additional digital and analog I/Os.
Signal boards:
One signal board can be connected to all S7-1200 CPUs, allowing you to customize the S7-1200 CPUs by adding digital or S7-1200 analog I/Os to the controller without affecting its physical size. The modular concept provided by the SIMATIC S7-1200 allows you to design a controller system to exactly fit your application needs.

Memory 
Up to 50 KB of integrated work memory is provided with a floating boundary between the user program and user data. Up to 2 MB of integrated load memory and 2 KB of integrated retentive memory are also provided. The optional SIMATIC S7-1200 Memory Card provides an easy way to transfer programs to multiple S7-1200 CPUs. This card can also be used for storing miscellaneous files or to update the firmware of the controller system.

Integrated PROFINET interface
S7-1200 PLC: The integrated PROFINET interface is used for programming, as well as for HMI and PLC-to-PLC communication. Additionally, it supports communication with third-party devices using open Ethernet protocols. This interface features an RJ45 connector with auto-cross-over functionality and provides for data transmission rates at 10/100 Mbit/s. It supports up to 16 Ethernet connections and the following protocols: TCP/IP native, ISO on TCP, and S7 communication.

SIMATIC S7-1200 Integrated technologies
Integrated technology for counting and measuring, closed-loop control and motion control make the SIMATIC S7-1200 an extremely versatile system for many types of automation tasks.

High-speed outputs for speed, position or duty cycle control
S7-1200 Two high-speed outputs are integrated into the SIMATIC S7-1200 controller for use as either pulse train outputs or pulse-width-modulated outputs. When configured as a PTO, a 50 percent duty cycle pulse train is provided at a rate of up to 100 kHz for the open-loop speed and position control of stepper motors and servo drives. Feedback for the pulse train outputs is provided internally using two of the high-speed counters. When configured as a PWM output, a fixed cycletime output with a variable duty cycle is provided for controlling the speed of a motor, position of a valve, or duty cycle of a heating element.

PLCopen motion function blocks
The SIMATIC S7-1200 supports the open-loop speed and position control of stepper motors and servo drives. This functionality is easily configured using an axis technology object along with the internationally accepted S7-1200 PLC open motion function blocks included within the engineering system SIMATIC S7-1200 STEP 7 Basic. Absolute, relative and velocity moves are supported in addition to home and jog functions.

S7-1200 Drive commissioning control panel
The drive commissioning control panel included with the engineering system SIMATIC S7-1200 STEP 7 Basic simplifies the start-up and commissioning of stepper motors and servo drives.
It provides both automatic and manual control of a single motion axis as well as online and diagnostics information.

S7-1200 PID functionality for closed-loop control
The SIMATIC S7-1200 supports up to 16 PID control loops for simple process control applications. These control loops are easily configured using a PID controller technology object and the supporting editors provided within the engineering system SIMATIC S7-1200 STEP 7 Basic. Additionally, the SIMATIC S7-1200 supports S7-1200 PID auto-tuning to automatically compute the optimum tuning values for the gain, integral time and derivative time.

S7-1200 PID commissioning control panel
The S7-1200 PID commissioning control panel included within SIMATIC STEP 7 Basic simplifies the loop tuning process. It provides both automatic tuning and manual control capabilities for a single control loop and it also provides a graphical trend view of the tuning process.
