6ES7221-1BH32-0XB0 Siemens S7-1200, digital input SM 1221

The SIMATIC S7-1200 small programmable controller fully meets the system requirements of small and medium-sized automation. In the research and development process, the seamless integration and efficient coordination of systems, controllers, human-machine interfaces, and software have been fully considered, and effective solutions, especially meeting the requirements of

Completely different automation requirements in various applications.

SIMATIC S7-1200

The innovative system solution in the manufacturing industry - the modular controller SIMATIC S7-1200 controller has the characteristics of modularity, compact structure, and comprehensive functionality, which is suitable for various applications and can ensure the long-term safety of existing investments. Due to the expandability of this controller

The flexible design of the exhibition meets the high standards of industrial communication and communication interfaces, as well as comprehensive integrated process functions, so it can be integrated as a component in a complete comprehensive automation solution.

Communication module integration process

The integrated PROFINET interface is used for programming, HMI communication, and communication between PLCs. In addition, it also supports communication with third-party devices through an open Ethernet protocol. This interface comes with an RJ45 connector with automatic cross over function,

Provide a data transfer rate of 10/100 Mbit/s, which supports an additional 16 Ethernet connections and the following protocols: TCP/IPnative, ISO-on-TCP, and S7 communication.

SIMATIC S7-1200 CPU * can add up to three communication modules. The RS485 and RS232 communication modules provide connections for point-to-point serial communication. The configuration and programming of this communication adopts extended instructions or library functions, USS driver protocol, Modbus RTU master station, and

The slave protocols are all included in the SIMATIC STEP 7 Basic engineering configuration system.

High speed input

The SIMATIC S7-1200 controller comes with up to 6 high-speed counters. Three inputs are 100kHz and three inputs are 30kHz for counting and measurement.

High speed output

The SIMATIC S7-1200 controller integrates two 100kHz high-speed pulse outputs for controlling the speed and position of stepper motors or servo drivers. Both outputs can output pulse width modulation signals to control motor speed, valve position, or heating element duty cycle

.

storage

The variable boundary between user programs and user data can provide an additional 50KB of integrated working memory. At the same time, it also provides an additional 2MB of integrated loading memory and 2 KB of power down retention memory. SIMATIC memory card is optional, allowing for easy program transfer

Up to multiple CPUs. The card can also be used to store various files or update the firmware of the controller system.

Scalable and flexible design

Signal module

Up to 8 signal modules can be connected to CPUs with high scalability * to support more digital and analog inputs
