# Main: APM.CTRL_UNITS - APMonitor Option

 Type: Integer, Input
Default Value: 1
Description: Model time units
1=seconds
2=minutes
3=hours
4=days
5=years


CTRL_UNITS are the time units of the model. This option does not affect the solution but does affect the x-axis of the web plots. The time displayed on the web plots is shown according to the HIST_UNITS option but scaled from the model units as specified by CTRL_UNITS. The valid options are 1=sec, 2=min, 3=hrs, 4=days, and 5=yrs. If CTRL_UNITS=1 and HIST_UNITS=2 then the model is in seconds and the web plots have model predictions and measurements that are displayed in minutes.
