Note
Know-how protected use of the UssCyclic user block in a library is not possible.
Reason:
The USS_DRV system FB cannot put its data into the InstUssCyclic instance DB
of the calling UssCyclic block as a multi-instance; it uses the InstUssDrv single
instance. This is necessary as the USS_PORT system FB can only access the
entire instance DB of USS_DRV via its USS_DB formal parameter of the
USS_BASE data type; it cannot access an instance data block within
InstUssCyclic.
3.1.3 Implementation with SIMATIC S7-1500
Use the following system instructions:
 USS_Port_Scan
to process communication via the USS
®
network
 USS_Drive_Control
to prepare the send data and evaluate the response data
These system instructions can be found in the Instructions task card,
Communication.
