3.2 Inserting a task or redundant task
In the process station the actual programs run into the task. The programs are edited either using
Instruction Lists or Sequential Function Chart.
A redundant task has so-called redundancy data. These are data of the process image and of the
function blocks for which a data adjustment is performed after each cycle. This ensures that a re-
dundancy toggle can take place at any point in time.
So that the data of a redundant task are redundancy-capable, all variables of a redundant task
must be written in process image mode.
Not only the redundant task (TASK/RED), but also tasks of the previous type (TASK) can be con-
figured under the redundant resources. Thus only those functions of the user program which also
actually have to be redundant need to be configured redundantly within a redundant resource.
