Static SystemConfig

SystemConfig files are optional. They describe static configurations of agents and are therefore an alternative to the dynamic sampling of an agent during runtime. The schema is the same as for the SystemConfigBlueprint.

SSP

One usecase for the static SystemConfig is System Structure and Parameterization (SSP). We use SSP to chain multiple FMUs together, which transfer data between them during one time step. SSP is added to the SystemConfig like any other Component. It requires the following parameters:

Tag	Description	Mandatory
id	Id should be set to “SspPath”	yes
type	type should be string	yes
unit	not used	no
value	relative path to the ssp file relative to the configuration path	yes

Example

            <component doc="SSP">
                <id>SSP1</id>
                <schedule>
                    <priority>50</priority>
                    <offset>0</offset>
                    <cycle>100</cycle>
                    <response>0</response>
                </schedule>
                <library>Algorithm_SspWrapper</library>
				<parameters>
                    <parameter>
                        <id>SspPath</id>
                        <type>string</type>
                        <unit/>
                        <value>ConnectionTest.ssp</value>
                    </parameter>
                </parameters>
            </component>

Connecting SSP with OpenPass

During OpenPass Simulation, information is communicated via osi messages between the Simulation Core and SSP. Like any other component communication, these connections need to be explicitly declared as connections in the SystemConfig. One connection is defined with the following attributes:

Tag	Description	Mandatory
id	unique identifier for connection	yes
source	pair of sending agent component and local link id	yes
target	pair of receiving agent component and local link id	yes

Example

           <connection doc="SSP">
                <id>502</id>
                <source>
                    <component>SSP1</component>
                    <output>0</output>
                </source>
                <target>
                    <component>PrioritizerDynamics</component>
                    <input>1</input>
                </target>
            </connection>
