blockTimer

Timer measuring the time from the time instant where the Boolean input became true

Extends from Modelica.Icons.ObsoleteModel (Icon for classes that are obsolete and will be removed in later versions).

Information

Timer with option to accumulate time until it is reset by an input signal.

Each time the Boolean input u becomes true, the timer runs, otherwise it is dormant.

If the parameter accumulate is false, the timer is set to zero each time the input u becomes false. The value of input reset will be ignored.
If the parameter accumulate is true, the timer accumulates time, and the timer is set to zero only when the value of the input reset becomes true.

Type	Name	Default	Description
Boolean	accumulate	false	If true, accumulate time until Boolean input 'reset' becomes true, otherwise reset timer whenever u becomes true

Type	Name	Description
Buildings.Controls.OBC.CDL.Interfaces.BooleanInput	u	Connector for signal that switches timer on if true, and off if false
Buildings.Controls.OBC.CDL.Interfaces.BooleanInput	reset	Connector for signal that sets timer to zero if it switches to true. The input value will be ignored if the timer does not accumulate time
Buildings.Controls.OBC.CDL.Interfaces.RealOutput	y	Timer output
