Programming with TAPPS2 / CAN bus
25
CAN bus
The CAN network allows communication between CAN bus devices. When analogue or digital values
are sent via CAN
outputs
, other CAN bus devices can utilise those values as CAN
inputs
.
Up to 62 CAN bus devices can be operated in one network.
Every CAN bus device must be given its own node number in the network.
The
cable topology
of a CAN bus network is described in the installation instructions.
If a CAN input or CAN output is inserted into the drawing, the device settings can be defined for the
first time. These settings then apply to all other CAN elements as well.
CAN settings for the
converter
The bus rate setting only applies to
the primary CAN bus network.
These settings can also be made in the "File / Settings / Device settings..." menu:
Primary CAN bus network Potential-free CAN bus network
Node
Definition of a
unique
CAN node number (setting range: 1-62). The node number applies to
both
sides
of the bus converter. The factory-set node number of the converter is 48.
