3.7.2 Fieldbus bit rate and fieldbus length
Note
The maximum permissible fieldbus segment lengths de-
pend on the bit rate used. You will find detailed informa-
tion in the manuals for your control system or bus inter-
face, or in CiA specification DS 102.
• Observe the maximum permissible segment length
(cable length without repeater) if you connect the MTR-
DCI to a fieldbus segment.
• Avoid branch lines.
Note
• Refer to the manuals for your control system or bus in-
terface in order to ascertain which T-adapter and maxim-
um branch line length are permitted for your controller.
Also take into account the sum of the branch line lengths
when calculating the maximum permitted length of the
fieldbus cable.
Bit rate Maximum segment length
1000 kbit (1 Mbit) 40 m
20 kbit 1000 m

the bit rate
Notes on setting the bit rate and further bus parameters on
the control panel can be found in section 5.2.7.
