MATLAB: Does xPC Target 5.5 not recognise the PCI-PDISO8 Relay Card

pci-pdiso8pdiso8Simulink Real-Timexpc target

I am using MatLab 2013b on a 64-bit host machine and xPC Target 5.5 with a setup that includes a Measurement Computing PCI-PDISO8 Relay Card. When I perform the getxpcpci('all') command it returns 'unknown device' for this card (other cards are recognised). A quick search on the MatLab Answers page led me to the following link:

http://www.mathworks.com/matlabcentral/answers/91561-why-does-xpc-target-not-recognize-my-measurement-computing-pci-pdiso8-board

This link claims the issue should have been fixed in MatLab 7.1 but for older versions there is a process to follow. I tried following the process anyway with the new files and it still didn't work.

Are you sure this bug has been fixed/not re-introduced in more recent versions of MatLab?

It turns out that Measurement Computing (the card manufacturer) had performed an update to the card changing the register addresses that the xPC driver should have been reading and writing to but forgot to inform Mathworks. This has now been resolved and updated drivers are available upon contacting Mathworks.

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

This problem happens due to a mismatch in the DeviceID field. To work around this issue, download and replace the attached zip file which contains both DI and DO driver files and their respective DLLs. Here are the required steps:

1. Quit MATLAB

2. Rename the following files:

$MATLAB\toolbox\toolbox\rtw\targets\xpc\target\build\xpcblocks\dicbpcipdisox.c

$MATLAB\toolbox\toolbox\rtw\targets\xpc\target\build\xpcblocks\dicbpcipdisox.dll

$MATLAB\toolbox\toolbox\rtw\targets\xpc\target\build\xpcblocks\docbpcipdisox.c

$MATLAB\toolbox\toolbox\rtw\targets\xpc\target\build\xpcblocks\docbpcipdisox.dll

(where $MATLAB is the MATLAB root directory on your machine, as returned by typing

matlabroot

at the MATLAB command prompt.)

Rename the file to filename.c.old or filename.dll.old

3. Download the attached PDISO8.zip file to a temporary directory. Unzip the PDISO8.zip and extract the new files to the same directory mentioned in step 2.

4. Restart MATLAB

5. After restarting MATLAB, issue the following command at the MATLAB prompt:

rehash toolboxcache

Please note that MEX-files generated with one release of MATLAB are not guaranteed (or expected) to work with a different release of MATLAB. This is due to changes that may occur in the MEX-file libraries between releases of MATLAB. The attached DLL files were compiled for xPC Target version 2.7.2 (R14sp2). If you are running an older version of MATLAB you might have to recompile the attached C files to regenerate new MEX-file DLLs compatible with your current MATLAB version. This can be done using the MEX function as follows:

   mex myMexFile.c
