.Buildings.Obsolete.Controls.OBC.CDL.Logical.Timer

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.
