Data record structure (FB-input = data from the FB-Master):
Data record structure (FB-output = data to the FB-Master):
Example:
In this example the PB-Idx (In) and PB-Idx (Out) equal 8
Please note:
The counting starts at index "0" = 1. byte, i. e. in our example the value "8" corresponds to the 9.
byte!
We want to query the manufacturer hardware version (object - index 1009h) from a connected
CANopen
®
Slave. The CANopen
®
Slave has the Node ID = 5.
The Data-Len Request’s size has to be selected as large as the receive data length that is mai-
mally to be expected! Otherwise data that exceeds the set length is cut off.
If the size Data-Len Request is the same or larger than the receive data length, then the actual
data length comes back as Data-Len Response.
