4.4.2.2 Approved CoDeSys version
The following product component versions are approved for creating safety-oriented applications:
Type of product component
Programming system
The CoDeSys version can be checked via "Help" – "About". The correct version of the runtime system is indi-
cated by SIL 3 approval of the control system through the German Technical Inspection Association (TÜV).
4.4.2.3 Control-specific application notes
Safety controllers require a special procedure for loading safety-oriented applications. In CoDeSys, the
download of the bootproject is considered as safe, as it is secured by the appropriate mechanisms.
The procedure using CoDeSys is:
n Compile the user application
n Connect to the controller. This is secured by password protection. It causes automatic compile of user
application, if needed.
n Execute menu item "/Online/Create Boot Project"
n Reboot the controller, causes loading and starting of the application.
All online commands like the following disable the safe operation:
n Download
n Online change
n Set breakpoint
n Write values
n Force values
n Trace
Single cycle
n
n Start/Stop
n Flow control
The variable monitoring in online mode does not disable the safe operation.
4.4.2.4 Application creation procedure
Application creation must follow the guidelines of relevant safety standards, e.g., IEC 61508 ed. 2 for func-
tional safety and DIN ISO 13849 for machinery. In addition to comprehensive documentation of require-
ments, architecture and module interfaces, this also includes full functional testing of all parts of the safety-
oriented application. This test must be carried out with the machine in its final configuration including
mechanical, electrical and electronic components, sensors, actuators, and software. Testing in a special test
environment, for example using a debugger, may facilitate passing the final test, but cannot be used as a
substitute.
