Reading another thread where this started to be a heated topic and became curious. Realistically, what is the difference between utilizing a JACE as your "critical equipment" controller as compared to another device? Now let me be specific, I mean a dedicated JACE with I/O modules for this purpose.
Both are suseptible to the same dangers. Both basically have the same weaknesses and similar strengths.
I would lean toward the JACE for more flexibilty, but that probably comes from my lack of experience with some of the other "better" controllers on the market.
