Figure 5-34 Establishing the task level

Within the Run Sequence menu, select Edit, and then Predecessor for In-

stallation, to ensure that the function modules selected from the library will be im-

plemented into the desired task level (Figure 5-35).

Figure 5-35 Assignment of function modules to the selected task level

The proper assignment is important for several reasons. For example, if interlocking

logic were to be set up in the measured values task level, indications would constantly

be created by the cyclical processing, filling the buffer unnecessarily. On the other

hand, the interlocking condition at the moment of a switching operation may not be

processed at the right time, since measured value processing is done cyclically every

600 ms.
