I have a SEL3530-4 RTAC that I am trying to use to send MODBUS data to openHistorian. Right now I’m playing with it on my desktop and if I can get it working I plan on installing on a linux server later on.
I’m having trouble understanding how to set things up so information is being recorded into the openHistorian. I have the RTAC configured to send a single analog value to the OH. I picked the neutral unbalance current in a double wye filter bank as a sample tag.
In the web interface if I open up ‘Devices’ and click ‘RTAC’ and then click ‘Connect’ I can see the tag with the correct analog value displayed. However, if I navigate away from this page the connection to the RTAC closes and data transfer between the RTAC and OH stops. Further, if I ‘Monitoring’ -> ‘Trend / Export’ no points are available for selection and trending.
I can’t help but shake the feeling I’m missing some basic configuration step, but I can’t find much detail in the help section.
