ETS-Parameters line coupler - Application description line repeater
7. Application description line repeater
Line repeaters do not use a filter table. A received telegram is routed to all lines irrespective of in which line it is processed. It is therefore not important whether the
telegram is triggered within a line or whether it is sent from an upper line to a lower line via a coupler.
When an error occurs during transmission of a telegram according to the physical address of a receiver the line repeater is able to repeat the telegram. With the param-
eters „Physical:
Repetition if errors on main line/on sub line“ this function can be set separately for both lines.
In case of routing a group telegram with not receiving an acknowledgement or in case of a bus device detecting a transmission error the line repeater repeats the
telegram three times.
With the parameters „Group: Repetition if errors on main line/on sub line“ this function can be adjusted separately for both lines.
