Subject: Experiences using RS-485 Multi-Drop with StreamDevice?

Dear all,

We have a system being developed with a large number (>100) controllers that are linked through many chains of RS-485 multi-drop lines connected to Moxa boxes for remote access.

Has anyone used StreamDevice in such a setup and could share experiences? What to avoid? What to push for?

One more interesting thing: the client is expected to send a unique id with each request that gets returned by the response, so that incoming messages from the controller can be matched to outstanding requests. Has anyone implemented such a mechanism using StreamDevice?

Thanks for any hints,
~Ralph
