When assigning a PDO observe the respective length of the objects!
Processing of the received process output data (R-PDOs) can be influenced as described below.
6.7.4 R-PDO control
This object can be used to influence the internal processing of the received process output data (R-PDOs).
A bit is allocated to each communication object which can be mapped to a R-PDO .
If the corresponding bit = 0, the received data for the object are used immediately; i.e. the resulting command is executed
immediately.
If the corresponding bit = 1, a check is first made whether there has been a data change for the corresponding object, and only
then are the data used or the resulting command generated.
Bit 15 = 1 achieves that PA data for the LAGE_ZIEL are used, but the running move is only carried out with the flank reversal
(0->1) of the New Set Point Value bit (control word bit 4).
