• Catalog containing an extensive set of standard blocks, including:
  • Logic blocks
  • Pulse blocks
  • Counter
  • Timers
• Facilitation of test and startup through integral online monitoring and debugging.
• The CPU status is displayed in test mode. The display encompasses the statements online/offline and RUN and STOP online.
• Added documentation options:
  Linking to project-wide documentation system DOCPRO.
• Message configuring for WinCC.

Expandable libraries:
The standard libraries can be expanded by means of separate application/technology-oriented blocks in the STL, LAD, FBD, S7-GRAPH and S7-HiGraph programming languages (for SIMATIC S7 in each case). Blocks can have as many as 160 inputs/outputs.
The F standard libraries can be expanded in the F-LAD and F-FBD programming languages by means of separate application-specific or technology-related blocks. The F blocks are called up and processed in a dedicated F runtime group using the F call function. The maximum interval between two calls can be parameterized in this case.

• Syntax check:
  To detect program errors already when creating blocks.
• Display and operation attributes optimize the handling of the blocks.

Test and debug functions

In test and debug mode, all STEP 7 test functions are available.

Password protection

Distributed Safety V5.1 and higher completely supports password protection of the CPU.

Software requirements

• Distributed Safety V5.2 executes with STEP 7 V5.1 SP6 and higher.
• Distributed Safety V5.4 executes with STEP 7 V5.3 SP3 and higher.
