| Re: [volttron-dev] Platform Driver: Device scrape interval below 1 second |
|
Hi Joe, I do recall personally testing intervals of less than one second, but that was a long time ago, and it is entirely possible that I am forgetting custom changes I made for it to work. Looking
at the code which is generating the warning, though, it appears to explicitly disallow intervals of less than one second. I don’t see a definitive reason why this would have been necessary, but the code to do it has been there for a long time. I will work
on testing a change to remove this restriction, but If you are OK being a guinea pig, check out and try this branch on my fork: This branch removes the restriction on polling intervals. It also merges an old fix I made (which we discussed previously) to add pad registers to the ModbusTK driver. I have not yet had a
chance to test either of these. I will do so shortly, though, and will let you know when I have. Meanwhile, if you do try this branch out, let me know how it goes. Dave From: Thompson, Joe <jthompson@xxxxxxxx>
Check twice before you click! This email originated from outside PNNL. 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! Joe Thompson Technical Leader Electric Power Research Institute Energy Storage and Distributed Generation
