RTG_LOGIC

Function
The RTG_LOGIC function block, which is a standard function packaged in the
Failsafe Blocks library, provides new functionality to interface the F-run-time groups
and the shutdown logic.
The RTG_LOGIC function block is automatically placed by the compiler in a CFC
chart named @F_ShutDn.
Note
No other logic shall be permitted to be placed within the @F_ShutDn CFC.
Connections may not be made to any inputs or outputs of these blocks. Any logic
placed within the @F_ShutDn CFC will automatically be deleted during the
compile.
I/Os
The inputs and outputs will not be explained here since this is logic that the system
automatically generates.
