Compact integrated controller, HMI, programming software

Siemens Simatic S7-1200 controller and HMI Basic panels both use new Simatic Step 7 Basic software.


Siemens Energy & Automation , Inc. has introduced a new compact controller solution composed of the Simatic S7-1200 controller and Simatic HMI Basic panels that can both be programmed with Simatic Step 7 Basic engineering software. The S7-1200 compact controller includes built-in Ethernet, high speed motion control I/O, and onboard analog I/O, as well as HMI panel connectivity to minimize space requirements and the need for additional hardware for small control systems.

“The S7-1200 and Step 7 Basic engineering software form the first of a new breed of compact controllers that integrate the controller, HMI, and networking functionalities with one program, enabling users to focus on developing machine or system designs--their core intellectual property that keeps them competitive,” says Raj Batra, vice president, automation and motion division, Siemens Energy & Automation.

Simatic S7-1200 controller and Simatic HMI Basic panels that can both be programmed with Simatic Step 7 Basic engineering software.

The Siemens S7-1200 compact controller is offered in a variety of I/O combinations and power supply options, including nine models of either VAC- or VDC- supplied units with combinations of DC or Relay I/O.

The new Simatic Step 7 Basic engineering software provides a single user interface. Automated interfaces between controller and HMI configurations provide appropriate functionality when needed, lessening the potential for error common with manual entry. Task-oriented and intuitive editors in the software provide a high degree of user-friendliness and engineering efficiency.

Tight integration between small controllers, HMI panels, and the engineering software satisfies machine builders’ needs for flexible control systems that can perform multiple operations and require minimal changeovers. Using the integrated capabilities of the unit, manufacturers can add new equipment and retool production lines more easily with less engineering cost and time.

Scalable hardware

Traditional nano- and micro-PLC product lines often lack scalability in controller selection or are limited in expansion options, forcing automation users to unnecessarily migrate to larger more costly systems,” says Paul Ruland, product marketing manager for S7-1200. “The S7-1200 compact controller is offered in a variety of I/O combinations and power supply options, including nine models of either Vac- or Vdc-supplied units with combinations of

Signal modules are available in 8-, 16-, and 32-point input, output, and combination models supporting dc, relay, and analog I/O signals. Additionally, innovative new signal boards available in 4-channel digital or 1-channel analog I/O snap into the front of the S7-1200 controller enabling I/O upgrades without consuming additional enclosure space. This scalable design can accommodate applications from 10 I/O points

The Simatic S7-1200 also includes an integrated 10/100 Mbit Ethernet communications port with Profinet protocol support. Other features include up to 50 KB total memory with a floating boundary between user and program data, a built-in real-time clock/calendar, and 16 PID loops with auto tune capability.
