Using PLC?

[John Carroll]

I have considered trying exactly this.  The robust input and output 
as well as the available interfaces make them appealing.  My main 
concern is that in order to make the hardware fast enough to keep 
up with an engine, one would have to hijack the software and take 
over the entire operation of the device.  I bet this will be about as 
much work as doing the same thing to an automotive ECU and the 
underlying base of engine oriented software does not exist.  One 
would have to bootstrap the entire project.

If some other group is dedicated to modifying PLCs the way this group 
is dedicated to ECUs, many of the problems may have been solved.

A phone call to PLC Direct at 800-633-0405 will get anyone a catalog 
of current PLC technology.
