The PLC Software (Step 7 Professional) is a programming software that is required for programming Siemens programmable logic controllers.

The WinCC Advanced development software is a Windows-based application suite, produced by Siemens, which simplifies the creation of graphic human-machine interfaces (HMI), such as operator interface solutions, to monitor and control machines and industrial processes.

A completed application provided with WinCC can be used with a S7-1500 Siemens PLC and a 3531 System to perform process control experiments. The HMI database can be loaded directly on an Industrial PC. Your applications can also be designed to run on a computer.
