A Niagara G3 Microsmart driver is being used to integrate an existing system of Microsmart controllers. Mode control points are used to command heating stages at different setpoint values. How can the stage setpoints be modified (identified as the PVALU element) from the Niagara G3 station? They are learned into the Niagara G3 station as Numeric Points and do not have the option to be writable.

Modification of stage setpoints to be provided to the customer on the system graphic.
1. Add the PVALU element for the specific Mode Control point to the database:
2. Add text to the Command String and modify the Index value to match the specific PVALU element to be changed (ie: Index = 6 maps to PVALU,6 in the Mode Control point):
Now, a right-click on the numeric point provides an action item and the ability to change the PVALU element for the Mode Control point down in the Microsmart Driver.
