Hi everyone,
We’re working on a setup where field devices (like PMUs) need to send high-rate data (on the order of 20 ms intervals) into a single centralized historian. We have a choice of protocols: DNP3, OPC UA, or IEEE C37.118 + other …. We want to figure out the best way to reliably achieve that 20 ms logging interval.
Our main question is: should we route the data directly from the field devices to the historian to meet that timing, or can we reliably use Ignition as an intermediary and still hit that sub-20 ms interval? We’re aiming for one centralized historian in the end, but we’re open to whichever architecture (direct or via Ignition) is best suited to maintain these high-speed logging requirements.
Any advice on the most efficient path and which protocol might handle this best would be greatly appreciated!
Thanks in advance
