Hi,

First time poster here, so apologies if this has been asked and answered...

Are there tags for a point that communicates the status of a piece of equipment or VFD? I see some tags that deal with other statuses (historical data availability, point writability, etc.).

I'm thinking a current switch or VFD status output to the BMS. I'd like to be able to filter my points on this to calculate system run times.

Thanks, J Parsons Envise

A current switch on an air handler can be defined with the following tags:

• discharge air fan run sensor

.....or the vfd speed feedback could look like this

• discharge air fan speed sensor

These links have some more examples
