STEP 7/Professional is the programming and configuring software designed for professional use with SIMATIC controllers. It includes powerful tools and functions for the varied tasks involved in an automation project.

STEP 7 Professional includes all the programming languages complying with the international IEC 61131-3 standard and therefore enables cross-company standardization and helps save high software engineering overheads.

It supports the user through all the stages of a development process for automation solutions, such as

• Installation and management of projects
• Configuring and parameter assignment of hardware and communications
• Symbol management
• Program generation for SIMATIC S7 target systems
• Loading programs on target systems
• Testing the automation plant
• Plant fault diagnostics

TEP 7 Professional consists of the following:

• The STEP 7 basic package including the well proven LAD, FBD and STL languages
• S7-GRAPH for graphic programming of sequential controls
• S7-SCL, the high-level language for programming even the most complex tasks
• S7-PLCSIM for off-line simulation of an automation solution.
