Safety related modules
Modules diagnostics are scanned every fast or normal scan interval depending on the application
configuration. When a fault if detected a diagnostic is reported and the associated function blocks fault pin
is asserted. Output modules are driven to their failsafe state either under controller direction or detection of
a loss of communication to its controller or scanner. The failsafe time out of communication loss with an
IO module is three scan cycles. Controller application will continue to execute based upon the applications
configuration.
