Interface Connection

[Ankith-Azista]

Hello
I am trying to add interface or connection between two ports so that I can establish the relation in a visualization format. I am uploading .sysml file into syson and I am not able to see the interface or connection present in the visualization. I have tried general view and interconnection view as well. The ports are present but the relationship between them is not.
When I am using syson to create an interface between them manually using the drag-drop features and then downloading the file in .sysml format the interface connection is not present in that.
Is there any solution for this or is that feature still under development in syson?

Hello,

Thank your for using SysON.
Could you share your .sysml textual file please?

For example, importing a .sysml textual file like this:

package Package1 {
	part part1 {
		in port port1In;
	}
	part part2 {
		out port port1Out;
	}
	connection interface1 connect part2.port1Out to part1.port1In;
}

then, once imported, create a new GeneralView diagram on Package1, and then drag'n'drop part1 and part2 on the diagram should display the connection between port1Out and port1In.

The import feature is not perfect and there may be some cases not handles yet.
May be you are in one of those cases (same for the export module).

Thank you for replying.

    part PLC_Main : PLC {
        port tcOut_TMM : TelecommandOutPort;
        port tcOut_FPE : TelecommandOutPort;
        port tcOut_DHU : TelecommandOutPort;
        port tmIn_TMM  : TelemetryInPort;
        port tmIn_FPE  : TelemetryInPort;
        port tmIn_DHU  : TelemetryInPort;
    }
    part TMM_Main : TMM {
        port tcIn  : TelecommandInPort;
        port tmOut : TelemetryOutPort;
    }
    part FPE_Main : FPE {
        port tcIn     : TelecommandInPort;
        port tmOut    : TelemetryOutPort;
        port imageOut : ImageDataOutPort;
    }
    part DHU_Main : DHU {
        port tcIn        : TelecommandInPort;
        port tmOut       : TelemetryOutPort;
        port imageDataIn : ImageDataInPort;
    }

    interface : TelecommandInterface connect
        PLC_Main.tcOut_TMM to TMM_Main.tcIn;
    interface : TelecommandInterface connect
        PLC_Main.tcOut_FPE to FPE_Main.tcIn;
    interface : TelecommandInterface connect
        PLC_Main.tcOut_DHU to DHU_Main.tcIn;
    }

this is a snippet of how I am defining things and how I am seeing them in sysON

I am new to this so I appreciate the help a lot.

You can use the "manage visibility" action on top right corner of graphical nodes to help you show/hide border graphical nodes:

I checked my installation and apparently I have an older version installed. Updating to the latest release fixed my issue.

Thank you for your help

Ok, yes you can use the latest 2026.5.0 release.
FYI, there is an official documentation here: https://doc.mbse-syson.org/
