-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Florian and Richard,
Thank you very much for pointing us in the right direction. As a matter of record, I'll provide what we were doing (incorrectly) and how we resolved the problem. Here is what we were trying to implement. x---------x x------x x-----------------x | Value |-------->| Gain |-------->| FB1111 Dig. Out | x---------x x------x x-----------------x Constant Gain Generic Slave We want the constant value to be modifiable by an external process via the pdcom interface. Consequently, we had to include a gain block to overcome the RTW error regarding rtB (http://lists.etherlab.org/pipermail/etherlab-users/2009/000547.html). The getVariables() method correctly returned the parameters '/example/Constant/Value' and '/example/Gain/Gain'. Our first error was trying invoke the subscribe() method on the parameters as a stream which resulted in a warning regarding event subscription. However, when we tried to subscribe to the parameters as an event we would get a segmentation fault. The matter was resolved by forgoing the subscription and just invoking the setValue() method directly on the parameters. As a follow-up, should we be able to subscribe to these parameters and if so how would that be done? Unfortunately, the pdcom example only shows how to receive inputs via subscribe(). Is there a more elegant solution for dynamically controlling parameters via pdcom? I just want to make sure that we're implementing our solution in the most intuitive way possible. Thanks again.
