Bus cable length
Depending on the baud rate and the cable type used (thick cable/thin cable), the following
bus cable lengths are possible:
Baud rate [kbps]
Bus cable lengths [m]
Thick cable Thin cable
125
500
100
250
250
500
100
If both thick and thin cable types are used, the maximum cable lengths can be defined
according to the baud rates as follows:
Baud rate [kbps] Max. bus cable length
125 500 m = L
thick
+ 5 L
thin
250 250 m = L
thick
+ 2.5 L
thin
500 100 m = L
thick
+ L

Note!
Select a baud rate in dependency of the data volume, cycle time and number
of nodes just high enough to suit your application.
External supply
The communication module is externally supplied with voltage via the DeviceNet cable at
the 5−pole plug connector (X225).
Note!
Use a safely separated power supply unit ("SELV"/"PELV") according to EN
61800−5−1.
ƒ The external voltage supply of the communication module is always required.
ƒ Communication with a standard device which is separated from the mains is not
possible.
