Command interlockings contain the definition of the switching actions as well as the definition of the command conditions. Command conditions are optional parameters that can be defined application-specifically.

Every action within a command interlocking can be extended with 'Command conditions'. These process-controlled interlockings prevent an unwanted execution of actions, depending on the current process status.

The command interlockings consist of 3 essential parts:

Actions

These define which command is executed and on which datapoints these actions should be applied and they parameterize the internal interlockings.

Condition variables

These define, which data points can be used in the command conditions.

Command conditions

These conditions make the execution of commands dependent on the current process status.
