Absolutely - and decisions often made by management and not the
engineers. Some of it is for ease of use, so an electrical engineer
can monitor a pump station or a power substation from his desk, "We'll
just put sensors on this network - and it will have its own VLAN,
that's safe." <skip a year> "We need to be able to control that pump
ASAP - do what you have to do."


Agreed, its not just ease of use, but cost of development. JCI or
Johnson Controls used to have a proprietary OS that used BACNET for
communication. Sometime around 2004 they decided that EmbeddedXP with
IIS' www and smtp services would be much less costly to use. They
didnt however think about how they would patch these systems.

Of course any sane person would have a private network for their
building controls, but still that only makes you as secure if you
control physical access to all of your ethernet cables.
