Re: [volttron-dev] Platform Driver: Device scrape interval below 1 secon

I know David responded already. 100ms modbus scans should be highly doable using python, but note whatever you are reading from the inverter may or may not be accurate at that scan interval. Please check with the inverter manufacturer to see what they say. 

Thanks

Hi Volttron Team, 

 

I was doing some speed testing with volttron reading from some modbus devices with the modbus-tk driver. I was hoping to try out polling rates under 1 second (500ms or even 100ms), but got this error in my logs:

Is there any way to enable these faster polling rates within volttron (im using volttron 8.1.3)?

 

Thanks!
