SINAMICS V20 at S7-1200/1500 via USS
Entry ID: 109480894, V1.0,
Open the newly created block UssCyclic_1. Now adjust the number of calls of
USS_Drive_Control in the block to the number of drives in the new
communication module. For the remaining calls of USS_Drive_Control, replace
the instance.
Open the cyclic interrupt OB Cyclic_interrupt_1. Here the call of the
UssCyclicInterrupt block can be retained. However, supply it with a new instance
data block.
The hwIdentifier input must contain a reference to the new communication
module.
The USS_DB input must contain a reference to the USS_DB tag. This tag is
located in the new instance data block of UssCyclic_1.
Compile the entire STEP7 program.
