STEP 7

STEP 7 basic software is the standard tool for the SIMATIC S7, SIMATIC C7 and SIMATIC WinAC automation systems. It enables the user to use the performance capability of these systems easily and conveniently.

STEP 7 contains convenient functions for all phases of an automation project:

• Configuring and parameterizing the hardware.
• Specifying the communication.
• Programming.
• Test, start-up and service.
• Documentation, archiving.
• Operating/diagnostics functions.

All functions are supported by the extensive online help.

STEP 7 is installed as standard on the Field PG M programming device. It is also available as a software package for a PC installation. For use with a PC, a PC module or PC adapter is required. STEP 7 allows several users to work on a project simultaneously. Write access from more than one user is prevented.

S7-SCL

S7-SCL (Structured Control Language) is a PASCAL-type high-level language that is optimized for the programming of programmable logic controllers.

S7-SCL supports:

• The fast and easy creation of programs.
• Improved quality of the PLC program.
• Clarity.
• Easier testing.

The user is then able to formulate time-saving and cost-effective solutions for automation tasks.

S7-SCL can be used in the SIMATIC S7-300 (CPU 314 and CPU 312C and higher are recommended), SIMATIC S7-400,SIMATIC C7 and SIMATIC WinAC automation systems.

S7-SCL has received the PLCopen Base Level certificate.

S7-GRAPH

The engineering software S7-GRAPH is used to configure and program sequences within a process in a standardized presentation format (according to DIN EN 6 1131-3). The sequence (e.g. manufacturing of a component) is subdivided into consecutive or simultaneous steps.

Subdivision makes the PLC program clearer and easier to analyze in the event of a fault. This is particularly helpful in manufacturing industry to prevent costly downtimes.

When working with S7-GRAPH, the user is presented with a modern Windows user interface with pixel graphics, windows technology and zoom functions.

The methodical procedure and clear presentation make S7-GRAPH efficient software for the description of sequential processes.

S7-GRAPH can be used in the SIMATIC S7-300 (CPU 314 and CPU 312C and higher are recommended), SIMATIC S7-400, SIMATIC C7 and SIMATIC WinAC automation systems.

S7-GRAPH has received the PLCopen Base Level certificate.

S7-PLCSIM

The simulation software S7-PLCSIM supports functional testing of the SIMATIC S7 user blocks on the PG/PC, independently of the availability of the target hardware. Program error detection and elimination can therefore be moved to an earlier phase of the project. This supports:

• Faster, less expensive initial start-up.
• Increased program quality.

S7-PLCSIM can be used for all user blocks and a selection of existing system functions.

The field of application ranges from the languages

• LAD, FBD and STL

through to all SIMATIC Engineering Tools:

• S7-GRAPH
• S7-HiGraph
• S7-SCL
• CFC (incl. SFC).

Extended application areas:

• S7-PDIAG
• WinCC (installed locally)
