Getting Started
11. Check again in the run-time group overview whether all the F-blocks are in the
F-blocks run-time groups as required.
Compilation of the Blocks
Choose the Chart > Compile > Charts as Program menu command to compile
your program. Activate the Generate Module Drivers option.
You will be prompted to enter a password for the safety program (see above under
Passwords). This password will be requested on future compiles.
You will be prompted for MAX_CYC time for every OB3x with a failsafe program.
After the charts have been compiled, the following control blocks are integrated
automatically by the "S7 F Systems" option package :
•
In the F-CycCo-Obxx chart F_CYC_CO, F_TEST, and F_TESTC (for tests)
•
In chart @F_TestMode the F_TESTM for Test Mode management
•
In chart @F_RtgDiagxx the F_PLK and F_PLK_O (for program execution
monitoring)
•
In a separate chart @F1 F_M_DI24 and F_M_DO10 (F module driver)
•
In a separate chart @F_ShutDn, the shutdown logic is created containing the
F_SHUTDN, RTG LOGIC, and standard logic blocks.
