Buildings.Utilities.IO.SignalExchange.Examples.BaseClasses

Contains base classes for signal exchange examples

Information

This package contains base classes that are used to construct the models in Buildings.Utilities.IO.SignalExchange.Examples.

Extends from Modelica.Icons.BasesPackage (Icon for packages containing base classes).

Model to be exported as an FMU

Buildings.Utilities.IO.SignalExchange.Examples.BaseClasses.ExportedModel

Information

This is an example of a model that would be compiled in BOPTEST if the original model were using the signal exchange blocks. Note that inputs are added to activate and set values of control signals that can be overwritten and outputs are added to read signals from the read blocks.

Extends from Modelica.Blocks.Icons.Block (Basic graphical layout of input/output block).

Connectors

Type	Name	Description
input RealInput	oveWriSet_u	Signal for overwrite block for set point
input BooleanInput	oveWriSet_activate	Activation for overwrite block for set point
input RealInput	oveWriAct_u	Signal for overwrite block for actuator signal
input BooleanInput	oveWriAct_activate	Activation for overwrite block for actuator signal
output RealOutput	rea	Measured state variable

Buildings.Utilities.IO.SignalExchange.Examples.BaseClasses.OriginalModel

Original model

Buildings.Utilities.IO.SignalExchange.Examples.BaseClasses.OriginalModel

Information

This is a model of a first order dynamic system with feedback control. Signal exchange blocks are implemented to overwrite either the setpoint or actuator control signals as well as read the output of the first order system.

Extends from Modelica.Blocks.Icons.Block (Basic graphical layout of input/output block).
