Redundant bus connection
AUMA Profibus DP devices can be connected with a second (redundant)
Profibus cable. If the bus on channel 1 fails, e. g. through cable break, the
slave automatically switches to channel 2.
This cable redundancy may only be applied after previous
integration test using the desired process control system!
.
For versions with AUMA plug/ socket connector (subclause 3.2):
Connect redundant bus cable to channel 2 in the same way as channel 1
(refer to connection diagram figure B-2).
.
For Ex-version with plug/ socket connector / terminal board (KP)
(subclause 3.7):
Connect cable B to terminal 6, cable A to terminal 7.
The termination resistor for channel 2 is connected through linking the
terminals 5 – 6 and 7 – 8.
.
For Ex-version with plug-in terminal connection KES)
(subclause 3.8):
Connect cable B to terminal 6, cable A to terminal 7 (figure D-2)
.
The termination resistor for channel 2 is connected through linking the
terminals 5 – 6 and 7 – 8.
The setting of the redundant bus connection is realised via the parameters
4 and 5 (refer to page 16).
