2.50.3 Command Processing
Security mechanisms in the command path ensure that a switch command can be carried out only if the test of
previously established criteria has been successfully completed. In addition to general fixed prescribed tests,
further interlocks can be configured for each resource separately. The actual execution of the command job
also is then monitored. The entire sequence of a command job is described briefly in the following:
