Virtual Links - BONFIGLIOLI actice Instruction Manual

4.11.5
A PDO telegram according to CANopen contains 0 ...8 data bytes. A mapping for any
kind of objects can be done in these data bytes.
For the system bus, the PDO telegrams are firmly defined with 8 data bytes. The map-
ping is not done via mapping parameters as with CANopen, but via the method of
sources and links.
Each function provides its output data via a source. These sources are defined via
source numbers. The input data of functions are defined via parameters. The link of a
data input to a data output is done via the assignment of parameters to source num-
bers.
Example 1:
In example 1, the two inputs of function C are connected to the outputs of functions A
and B. The parameterization for this connection is thus:
Function C
Example of a virtual link in VPlus:
The assignment of the operation modes to the software functions available can be
adapted to the application in question.
