Bus Terminal - Festo CTEU-PB Electronics Description

1. Installation

1.5.6 Bus terminal

1-20
Note
Each fieldbus segment must be terminated at the start and
end to minimise data transmission errors due to signal
reflections and attenuations.
To terminate, use a bus terminal network on both ends
•
of the fieldbus segment (see Fig. 1/6).
Never use more than two activated bus terminals within
•
a fieldbus segment.

Recommendation:
Use the fieldbus plugs from Festo for the bus terminal (see
Fig. 1/5). A bus terminal network that can be connected and
disconnected is integrated in the housing of this plug.
