STEP 7 Professional supports all IEC languages.

In addition to the LAD, FBD

• and
• STL
• languages familiar from STEP 7,

sequential function chart

• and
• structured text are also available.

An offline simulation of user programs created with these languages is included. STEP 7 Professional thus replaces the combination of the individual packages STEP 7, S7-GRAPH, S7-SCL and S7-PLCSIM.

A POWERPACK (conversion package) is available for customers who use STEP 7 already and wish to change. A valid STEP 7 license is required for purchasing the POWERPACK. A separate update service can be purchased for STEP 7 Professional.
