Routing The Can Bus Backbone - ProMinent DULCOMARIN II Assembly And Installation Manual

4.4 Routing the CAN bus backbone

Planning aids and requirements for the installation site
CAUTION!
Maximum backbone length
Possible consequence: Malfunctions.
– The maximum backbone length (without branching
cables) must be less than 400 m
CAUTION!
Maximum length of branching cables
Possible consequence: Malfunctions.
The T-pieces and connecting cables (branching
cables) enclosed with the modules (M-, A-, G-, N-, R-,
I- modules, CAN sensors and metering pumps with
CAN bus must be used.
Branching cables are the connections branching from
the CAN bus backbone to the modules.
The external modules can be placed in any sequence
along the CAN bus backbone. The operating instruc‐
tions show for example possible sequences of the
external modules.
Each CAN cable has a plug or coupling on each end
so that these can be coupled together in sequence to
create longer cables.
Rule
Arrange the external modules in groups for each pool.
First assemble and install the external modules and
their attachments. Only then should you connect the
external modules with the CAN bus backbone and with
each other via the the shortest route.
