Hi All,

Does if you can query to find a value in a tag for all points.

For example, creating a data table for all points in a certain device, but pulling the n:ordInSession Tag from each of them to display in the table.

Could have swore i've seen syntax like - bql select getTag(n:ordInSession) as 'Ord in Session' - but can't get it to work. Maybe I dreamt it. Or maybe this only works for direct tags?

Hey @AdBaker97

This might be a starting point:

station:|slot:|neql:n:ordInSession|bql:select displayName, ordInSession

A bit more refined to target a specifc slot path rather than the whole Station:

station:|slot:/Folder|neql:n:ordInSession|bql:select displayName, ordInSession, ord

@goseese

I wonder if you have any experience or pointers for a query I am trying to figure out.

Given I have a Jace8000 and I can execute this query to see all points on the controller.

/ord?station:|slot:/Drivers/NrioNetwork|bql:select%20*%20from%20control:ControlPoint

Returns a lis something like this. I cut out a lot of content and some of the columns to shorten this up.

slot:/Drivers/NrioNetwork/IO$2dR$2d34/points/DigitalInputs/SysA1DoorSwitch Open {down,stale} slot:/Drivers/NrioNetwork/IO$2dR$2d34/points/DigitalInputs/SysA6DoorSwitch Open {down,stale} slot:/Drivers/NrioNetwork/IO$2dR$2d16$2d1/points/SysA1Temp 302.0 °F {down,stale} units=°F,precision=1,min=-inf,max=+inf slot:/Drivers/NrioNetwork/IO$2dR$2d16$2d1/points/SysA4TempA 302.0 °F {down,stale} units=°F,precision=1,min=-inf,max=+inf ... slot:/Drivers/NrioNetwork/IO$2dR$2d16$2d1/points/Comp$233_Med_Temp_Alarm slot:/Drivers/NrioNetwork/IO$2dR$2d16$2d1/points/SysA1Defrost Defrost Off {down,unackedAlarm} @ 16 slot:/Drivers/NrioNetwork/IO$2dR$2d16$2d1/points/SysA5TempB 302.0 °F {down,stale}

My question is this.

On this jace in the web interface there is a [ Refrigeration ] and [HVAC] tab. Clicking on those shows there are refrigeration systems called System A1 System A2 .... System A6

Is there a query that I can execute to show me all refrigeration systems by name, or somehow get the config for the .px page?

Secondly, is there a way I can execute a contorl:ControPoint query as in above but only return controlPoints that have been associated/reated to for example SysA1. a door sensor or compressor might not have SysA1 in it's point name but it is showing as a part of that refrigeration system in the jace web UI.

Hi

This might be a starting point:

station:|slot:/VAV_Bldg_1|bql:select slotPath as 'Path', displayName as 'Display', out.value as 'Output Value' from control:NumericPoint where displayName like 'ZN_T' or displayName like 'STPT'

I think you would be able to change displayName like 'STPT' to something more specific such as parent.parent.displayName = 'System A1'.
They can then be conditioned to look for multiple specific matches.

station:|slot:/VAV_Bldg_1|bql:select slotPath as 'Path', displayName as 'Display', out.value as 'Output Value' from control:NumericPoint where parent.parent.displayName = 'System A1' or parent.parent.displayName = 'System A2'
