Water Pump Simulation Server

An OPC UA server that implements a simple water pump machine simulation.

Water Pump Simulation Server is created using OPC UA for the Water Pump and Qt Quick Water Pump 范例。

模拟

The OPC UA server runs a simulation of a machine containing two tanks, a water pump, and a valve. Water can be pumped from the first tank into the second tank and then be flushed from the second tank by opening the valve. Both operations have a user-configurable setpoint, allowing control over the amount of water pumped into or flushed from the second tank.

The following nodes exist on the server:

NodeId 函数
ns=2;s=Machine The folder containing the method and variable nodes for the machine
ns=2;s=Machine.State The state of the machine
ns=2;s=Machine.Tank1.PercentFilled The current fill status of the first tank
ns=2;s=Machine.Tank2.PercentFilled The current fill status of the second tank
ns=2;s=Machine.Tank2.TargetPercent The setpoint for pumping and flushing
ns=2;s=Machine.Tank2.ValveState The state of the valve of the second tank
ns=2;s=Machine.Designation A human readable designation of the machine for display purposes
ns=2;s=Machine.Start Call this method to start the pump
ns=2;s=Machine.Stop Call this method to stop the pump
ns=2;s=Machine.FlushTank2 Call this method to flush tank 2
ns=2;s=Machine.Reset Call this method to reset the simulation

All methods return Good in case of success and BadUserAccessDenied if the operation is illegal (for example, trying to start the pump if the first tank is empty).
