These probes are for use with the Simscape multi-domain physical modeling tools (Simscape, Sim Driveline, SimHydraulics and SimElectronics). The ssc_Probes.m file calls the library file containing probes for viewing the through and across variable for each domain. The ssc_dc_motor.slx model file is an example of how to use. See Help block for additional usage notes.

The switch to "To Workspace" was done to accomadate users who want to be able to have the Probes used in a library block (this is not possible with Scopes). As for the naming limitation, until I can figure out a better way, it is up to the user to provide unique names (I tried using genvarname, but there is a 64 char limit). The names are updated during model update. As for simlog, currently the only options are All or None. Once additional functionality is added here, I will be able to add a logging option.
Thanks for your feedback.
Tom, was there a reason you shifted to ToWorkspace blocks instead of scopes? It seems that the ToWorkspace block variable name does not change when the name of the block changes - also creates a problem if I use them within different subsystems with the same name.
I think a potential addition would be a right click menu configure option to switch between logging and no logging (using something like a variant subsystem). It could improve simulation performance if there are a large number of probes (I tend to use more probes and save it to the workspace because the simlog files become too large).
However, can you release an update for 2012b? In 2012b when evaluating the OpenFcn callback it tries to do close_system(gcs) which generates an error if the probe is at the top level of a model. If it is not at the top level of the model then it does not produce an error but it goes to the top-level of the model. You then have to use the back button to get back to your original spot.
The SimPowerSystems library contains voltage and current measurement blocks that output a Simulink signal. You could easily recreate what I have done by putting these blocks under the mask. You’ll also have to remove the PS->S block since it is not needed for SimPower.
I always use them, I modified the blocks a little bit to include them as a library in the Simulink browser.
Let me know if you are interested to get the modified version I created.

Adding useful links for File Exchange users.
18 Mar 2009
Updated to use more compact symbols for less clutter. Also added a physical signal scope.
18 Sep 2009
1. Changed name to Simscape Probes.
2. Added probes for the Pneumatic domain in r2009b.
3. Added internally referenced probes for quicker probing of across variables.
4. Added the GroupSignals GUI.

21 Sep 2009
Added copyright notice
08 Mar 2010
Changed release to 2009b
11 Mar 2010
Updated for release 2010a. Added probes for Magnetic domain and sl_customization.m for changing units and adding output port (see Info block for details)
11 Mar 2010
Updates for r2010a include probes for Magnetic domain and sl_customizations for editing units and adding output port. See Info block for usage notes.
23 Aug 2010
Assigned domain-specific default units to each probe and made unit visible when model is initialized using InifFcn callback.
15 Dec 2010
Updated for R2010b. Added sl_customization menu to toggle Goto tag between local and global. Default is now local, per user request.
17 Jun 2011
Updated for r2011a. Fixed minor bug (GroupSignals now only displays global signals)
12 Jun 2012
Updated for R2012a
30 Jul 2012
Fixed warning message bug found in R2012b pre-release. Updated current version (R2012a) and R2011b version in Archives directory to remove warning message when upgrading to R2012b.
14 Jan 2013
Updated for 12b
01 May 2013
Updated for R2013b. Replaced Simulink Scopes under mask with To Workspace blocks. OpenFcn callback plots workspave variables in MATLAB.
01 May 2013
Updated for 13a. Probes use MATLAB plots instead of Simulink Scopes.
22 Oct 2013
Updates for R2013b:
1. Added probes for Thermal Liquid domain
2. Replaced "To Workspace" method with signal logging.
3. Updated R2012a, R2012b and R2013a versions in the Archive directory to also use signal logging.
21 Nov 2013
One more update for R2013b that includes Probes for SimPowerSystems 3G domain in the Electrical library.
28 Apr 2014
Updated for R2014a. Added a MATLAB script ssc_Probes.m that calls the appropriate version based on the MATLAB release. The Archive folder contains versions older than the current release of MATLAB.
