A separate main and minor row can be created for each priority class. These main and minor rows consist of the traffic streams of the node. In principle, a traffic stream may only occur in one or no class (exception). The class in which a traffic stream is entered depends on its prioritisation.
Main series:
The traffic streams of a class are grouped according to traffic aspects and the groups are divided into a sequence (corresponds to a phase sequence). This sequence is then broken down into a main sequence.
Figure 85: Creating a main row
vs | plus searches for the next traffic stream in each of the parameterised main series that has a request. The pointer marks the traffic stream found.
Pointer delay:
Once the pointer has found a traffic stream, it tries to switch it to green as long as it has an request. It remains on it until it is green. The pointer delay allows the pointer to remain on the green traffic stream as long as the extension criteria are met. If the conditions for remaining on the traffic stream are no longer met, the next traffic stream in the main serie is searched for.
Minor streams with call:
A series of minor streams can be defined for each rank of the main sequence, which are selected when the main pointer points to the main stream in question. Each priority class has its own minor streams. Minor streams "with call" are only taken into account if they are registered. Traffic streams of other priority classes are permitted for minor streams with call. The traffic streams of the minor streams with call can be conflicting to each other. However, they may not be conflicting with the main stream!

Each priority class has its own main sequence. The main pointer follows this main sequence cyclically in the normal case (default setting of global flag Determination principle main sequence = ProcCyl). This means that the stages are built up cyclically traffic stream by traffic stream according to the main sequence table. |

Pointer delay |
|
The degree of freedom with which a switching on of friendly traffic streams is allowed during a stage (pointer is on a certain rank) is controlled with the pointer delay. As long as a main pointer is fixed on a rank, the corresponding secondary sequence is also active. The main pointer can be held on any rank. The pointer delay is active while green, provided the extension criterion is met. The main pointer does not move to the next rank until the comparison value of the pointer delay is reached. |

For each rank of the main sequence, a series of secondary streams can be defined, which are selected when the main pointer points to the main traffic stream in question. Each priority class has its own secondary series. Secondary streams "with call" are only taken into account in the case of a request. |
