Fieldbus bit rate and fieldbus length

Note
The maximum permissible fieldbus segment lengths are
dependent on the bit rate used.

•

Observe the maximum permissible segment length
(cable length without repeater) if you connect the MTR-
DCI to a fieldbus segment.

•

Avoid branch lines.

The bit rate is defined by the master and is automatically de-
tected by the MTR-DCI-...-PB.
