Query: Protocol & Module Recommendations for 500k-Point Waveform Data Integration into EPICS

[lvhh--- via Tech-talk <tech-talk at aps.anl.gov>]

Dear all,

We have a custom device generating 500k-point waveform data (float32/float64 arrays) and need to convert it to EPICS PVData for system integration. We seek guidance on two key points:

1.What communication protocol should the custom device support? Given the large waveform size, we prioritize high throughput, low latency, and structured data (to bundle waveform + metadata like timestamps/units). We wonder which standard industrial protocols are suitable? (e.g. VISA, GigE)

2. Which EPICS modules/tools simplify communication?

The data does not require real-time monitoring. Our local device has a cache, and data can be retrieved from the cache to be stored as EPICS PVs.

Any  documentation references are greatly appreciated!

Best regards,

Huihui
