[etherlab-users] RTW Output Assertion

Richard,

Thanks for replying. I suspect this is more of a RTW question than a
Pdcom question.

We actually are trying to bring up the output devices from Pdcom. We
currently have a functioning Pdcom test application based off the
example code provided. We haven't attempted a Variable::setValue() call
because the EtherCAT slaves don't have any output variables exposed.
That is, Process::findVariable() doesn't return any output variables.

We're using an IgH Starter Kit composed of EL1014/EL3102 input slaves
and EL2004/EL4132 output slaves. We're implementing the RTW example
design (example.mdl) which has the slave inputs connected to terminator
blocks and the slave outputs connected to function generators (pulse and
sine wave respectively).

What we would like to do is transfer the output slave stimuli to an
external application via the pdcom interface. However, all attempts to
provide different sources for the output devices (i.e. constant, input,
workspace, etc.) have been unsuccessful. We had expected to see
variables associated with the individual output channels similar to how
the input channels are presented. Is there an API call we're missing
perhaps?

Configuration Info:
* EtherCAT Master v1.4.1
* EtherLab v1.2-rc7
* Pdcom v3.0.1
* OpenSUSE 11.1 w/ 2.6.28.10 (RTAI v3.7.1)

Thanks in advance for your help.
