[etherlab-users] Help: Problem of reading model signal via pdcom

[JaysonDing]

Dear All
I have problem of reading the encoder input signal via pdcom.
I was able to run pdcom example code on my machine. The output are as 
following:
(Note: I add few codes to print out all the obtained variables.). The 
Simulink model is also attached.

It seems like Pdcom could only recognize parameters such as 
constant/value or gain/gain in Simulink model but not signal.
Can anyone tell me how to get access to the signals?  In the end, thanks 
for everyone of you effort. So I can make etherlab + pdcom run on my 
computer quickly. I also attached my system setting here FYI.
linux: 2.6.32.11
rtai:3.8.1
etherlab: 1.3-pre
matlab: 7.4.0.336
realtime workshop: 6.6

Look forward to your answer!
