Main cycle / sub-cycle
The sequence of the polling cycle can be structured on the master TIM by assigning
individual polling stations to the main cycle or the subcycle.
The subcycle is always activated at the end of the main cycle once all stations from the main
cycle have been polled. A configurable number of stations is called in a subcycle.
Following this, all the stations in the main cycle are polled again. This is followed by a
subcycle in which further stations that are assigned to the subcycle are called.
Master station
Station in the top hierarchy of a telecontrol network with ST7 protocol. It is connected to the
control system and the substations or node stations.
The WAN interfaces of the TIM are set to the network node type "Master station".
