Event scheduler is a useful tool for Dynamic simulation in HYSYS. It helps you to schedule your event in dynamic simulation. Dynamic simulation normally helps engineer to simulate different scenario (especially upset scenario) and testing functionality of control logic, etc.
For example, to simulate the start up of the plant, In the beginning, you need to open Valve-1, then 1 hr later, you need to close Valve-1, and start compressor and open Valve-2. These activities in sequence can be carried out manually when our integrator reaches our expected time. On the other hand, we may automate these activities using event scheduler in order to simplify work.

The structure of event scheduler in HYSYS as follow :
Schedule-->Sequence--->Event--->Action
Action is final layer to help us to do our expected work, such as specify variable, set controller mode etc. You should also specify the condition to do the action, such as elapsed time or even logic.
