In "S7 F/FH Systems" an extra substitute value is output for this value in case of overload,
overflow or wire break in the safety program.
In "S7 Distributed Safety", the substitute value 0 is provided in the process image for the safety
program instead of 0x7FFF (for overflow, wire break) or parameterized substitute value (overload).
