Priority flag:
Priority detection makes it possible to increase the priority value of a traffic stream. How the priority value is calculated can be found in the Control chapter. Priority detection can only be used if the PE value is also set.

REQU TYPE |
Request type |
|
The request type can be used to define from when the traffic stream waiting time is started. |
|
|
|
|
|
|
|
The traffic stream waiting time [twts] is started simultaneously with the first detector waiting time [twdet]. |
||
|
|
The traffic stream waiting period [twts] does not start until the signal frame plan begins. |

Green flag |
|
The default behavior of vs | plus is therefore that only those traffic streams are switched to green which are requested by their detectors / message points. With green detection, traffic streams can now be requested even if the assigned detectors have not requested anything. |

INAC |
Default behavior: A traffic stream can only be requested with detectors / message points. |
|
|
|
Duration |
A green request occurs immediately on red (continuous request of the traffic stream). |
|
|
|
BeginFS |
A green request is made as soon as its frame signal is present, even if no detector request is present. |
|

Only works in conjunction with PT on / off. |

prioF |
|
By default, vs | plus assigns a priority value to each traffic stream. This depends on the priority of the priority element in which the traffic stream is located and the rank of the traffic stream within the priority element. The priority value is decisive in the image composition. In case of simultaneous registration, the traffic streams are considered according to the priority value. |

Reaching the upper stage (stage 2) also depends on the "request type" identifier. With the "with PP" request type, the traffic stream does not go to stage 2 until a frame signal was present and the maximum waiting time was reached. |
