Issue
How to display a binary on/off value for fan the following hardware outputs for a Xenta 102-AX graphic page:
- Fan command
- Heat 1 command
- Heat 2 command
- Damper open
- Damper close
Environment
- Xenta 102-AX
- StruxureWare Building Operation
- TGML Graphics
Cause
Universal Outputs 1, 2, and 3 on a Xenta 102-AX are controlled via percent based values. Through hystereses, they will turn on and off. Without knowing the previous status of the output, values between 1% and 99% will be unclear as to the present value of the output.
Note: due to this SNVT being of a user-defined type, TAC Vista Workstation is unable to display these values. This solution can only be applied to a SmartStruxure Solution.
Resolution
- Navigate to the Xenta 102-AX object in Building Operation
- Drill down to Node Object [0] > nvoRawHwValues > Universal Outputs Current Value
-
Use the following signals for a true/false status of each command:
- Damper Drive Down State
- Damper Drive Up State
- Universal Output1 state (fan)
- Universal Output2 state (heat 1)
- Universal Output3 state (heat 2)
