We don't want ladder-logic. This box was suggested by folks
using them & the programmer is happy so far.

Its advantages are it's already built, has most of the
functionality we need in one box, and is inexpensive vs. the
labor of building anything.

We will be using other aspects, such as the analog inputs, RTC,
and the touch screen.

If you are aware of a different unit (....no matter if it's
called a PLC or an X-15) that does what this one does, plus a
wired Ethernet port, suggestions welcome.
