Hi

Alexey pointed me to an interesting bit of kit, that apparently already embodies some of the ideas from XPCA (specifically access to data via JSON)

http://www.anybus.com/support/support.asp?PID=542&ProductType=Anybus-CompactCom%20B40%20Brick

Might be worth grabbing one and having a play, if anyone has time. I'm going to try and source a bunch of PLCs for experimenting with as well, but later.

Cheers
Tom

I don't think it is needed, because it's useless without a host system. One can buy this starter kit which provides communication between the module and host application emulated on Windows. Actually I have one at my work place. Or one has to develop a PCB himself and connect it to a micro-controller. In my opinion, the deal isn't worth it.

Skipping the details of the low-level communication between the module and the host system I can say that the module's idea is very simple. In the host application the user describes the data to communicate like typified objects with ID by using the driver library written in C. When the module receives a HTTP request it requests the data from host application by ID, makes JSON documents and sends it back. All things happen almost automatically thanks the driver.
