Programming languages

STEP 7 V5.x
In SIMATIC STEP 7 V5.x, the following standard programming languages were
available:
Ladder diagram (LAD)
Function block diagram (FBD)
Statement list (STL)
The following languages can additionally be used as option package:
Structured Control Language (SCL)
Continuous Function Chart (CFC)
S7-GRAPH
Hi-GRAPH
Note
Please note that there can be a difference between a pure STEP 7 V5.x and a
PCS7 installation since PCS7 already includes options.
STEP 7 (TIA Portal)
In SIMATIC STEP 7 (TIA Portal), the following standard programming languages
are available to you:
Ladder diagram (LAD)
Function block diagram (FBD)
Statement list (STL) (not for S7-1200)
Structured Control Language (SCL)
S7-GRAPH (not for S7-1200)
Note S7-SCL is a programming language, which is similar to a high-level language.
Using S7-SCL, particularly more comprehensive functions can be implemented
easily and conveniently.
Therefore, we recommend that functions such as data handling, search
algorithms, copy functions, comparison functions, etc. be converted to S7-SCL
when migrating from STEP 7 V5.x to STEP 7 (TIA Portal).
