RPCSinumerik.ocx with LazActiveX

[D840]

Hi,

I want to connect to a Siemens SINUMERIK D840 using RPCSinumerik.ocx.
I created the typelib, and using the interface OLEServer I can send data to the D840.

Unfortunately the machine events are not processed by EventSinkInvoke, so I do get not the state of the D840.
I already tested with Delphi, where the events are handled properly.

Before I start analysing the ActiveXContainer:

Anyone who has experience with this component or even with SINUMERIK?

Regards Michael
