Thank you very much for your answer. I still have some questions. If the CtrlX device supports these two communication methods: Service Channel: Used for device configuration or parameter setting. It allows access to device parameters through the IDN (Identity Number) for configuring or modifying the parameters of servo drives. Process Data: Used for real-time data exchange, such as control commands and device status feedback. This method supports efficient and low-latency data transmission, suitable for control applications that require a rapid response. If the position under this data layer communicates via the process data pathway If the oscilloscope is synchronized in real time. When the oscilloscope listens to the data. Will there be a delay of five cycles in this case?

This works great, thank you for the information.

Hello, Like @CodeShepherd mentioned in this post the ctrlX Data Layer is a broker for data on the system and has no fixed limit in size or speed. It depends on the demands of all the applications running on the ctrlX CORE and the resources of the hardware. Yes there is a big difference between RT and NRT data transfer in the Data Layer. In case of NRT access to data, a request is sent for each access. This is not suitable for a cyclic and very fast access. Therefor you would use RT Data. In this case Data is exchanged via memory ranges, which is much faster. For details look at the ctrlX CORE runtime manual (chapter: ctrlX Data Layer - Exchanging data RT). Best regards, Nick

As the ctrlX Data Layer is a broker it has no fix size or limit as your application itself is holding the data and is providing the address that is them published. Data exchange capabilities is mostly a topic of the network architecture and performance. But for sure a more informant version of the ctrlX CORE can handle more requests in a shorter time.
