GetPorts

get the signal ports of the active MapleSim subsystem

Parameters

 options - (optional) equation(s) of the form name = value

Returns

 • list,list : lists of the active subsystem's ports: [InputPorts], [OutputPorts]

Options

 • toplevel : true or false
 Specifies whether the top-level ports should be returned regardless of the active subsystem setting.  Default is false.
 • returnacausal : true or false
 Specifies whether to also return possibly present active subsystem's acausal ports. If set to true, the procedure's return will be of the form list,list,list : [InputPorts], [OutputPorts], [AcausalPorts]. AcausalPorts is a list of lists, where each list describes ports for one acausal port and is of the form [flow variable, across variable]. Default is false.

Description

 • A:-GetPorts returns lists of A's active subsystem's input and output ports and optionally, acausal ports. If no subsystem is active, or the option toplevel is specified, the command returns an empty list of the inputs and a list of A's probe names for the outputs.
 • The A := MapleSim:-LinkModel() statement needs to be run prior to successfully using any of the ModelObject A's export functions.

Examples

 > $A≔\mathrm{MapleSim}:-\mathrm{LinkModel}\left('\mathrm{filename}'=\mathrm{cat}\left(\mathrm{kernelopts}\left('\mathrm{toolboxdir}'=\mathrm{MapleSim}\right),"/data/examples/RLCcircuit.msim"\right)\right):$

Getting the signal ports of the active subsystem (you are at the top-level):

 > $A:-\mathrm{GetPorts}\left(\right)$
 $\left[\right]{,}\left[{\mathrm{Main.Probe1.Vout}}{}\left({t}\right)\right]$ (1)

Setting the active subsystem an RLC circuit subsystem:

 > $A:-\mathrm{SetSubsystemName}\left("RLC"\right)$

Getting the signal ports of the RLC subsystem:

 > $A:-\mathrm{GetPorts}\left(\right)$
 $\left[{\mathrm{Main.RLC.InputSignal}}{}\left({t}\right)\right]{,}\left[{\mathrm{Main.RLC.OutputSignal}}{}\left({t}\right)\right]$ (2)
