Theory of Operation
The Integrity Checker comprises four different programs: the
Validator, the Checker, the GPL Checker and the GPL
Printer. The Validator and the Checker are used to validate
the compilation and download process of safety-related
application programs, including those implemented with
Ladder Logic and Scaling function block types.
The GPL Checker and the GPL Printer are used to validate
the compilation and downloading of Guarded Peer Link data
templates to assure that the link variables are configured
correctly.
Checking application programs with the
Validator and Checker:
Figure 1 is a data flow of the integrity check for the
W
INTERPRET Editor, Compilers, and download process. The
flow has two loops, one showing the check for the Editor, and
the other, the check for the Compiler and the download
process. Both loops use the application Source File, which is
CRC-protected on disk, as their reference.
