I have pressure test application that requires real time high resolution trend graph and trend reporting feature from a Pressure Transmitter.
For proof of concept, I have EPIC setup to generate tag data every 20ms.
I have a trial version of Ignition 8.1 on computer near EPIC.
On Ignition, I tried polling data via Opto22 Driver, it can only poll data at 300ms the fastest.
Using Node-Red, I send MQTT Data to MQTT Distributor to MQTT Engine, it can only received data at 300ms the fastest.
Any other way to stream data into Ignition?
Anyone can share a tool or script for Ignition to write data to file as it comes in that is low level (bypassing other input data processing)?
