Station

There are four types of stations (devices):

Station	Description
Master	Controls a network and gathers its slaves.
Slave	External I/O and other devices/ Slave outputs data as a response to a master’s output order and informs the master of its input status.
Repeater	Repeater is necessary for a network with more than 32 slaves to separate network segments.
Configurator	It configures a scan list of the slaves on the master device. Used only for network installation.

You can install the master anywhere in the network. You can connect up to 126 stations including server and repeater in the network. However, it is recommended to keep one device for the engineering device.
