Default and manual IO mapping

[CReese]

Hello,

I am trying to make my IO one-indexed, rather than zero-indexed, so I can map them directly to the same modbus addresses. When I go to manually change X0 to X1, or change the automatic settings to start at X1, it shows the input as ok as I enter it, but does not save the value. Strangely, It allows me to set the defaults for analog IO just fine. Is this a bug or something I am missing?

Thanks,
Colin

Maps must be byte aligned. To map on bit boundaries would cause an unacceptable performance hit.

Yes, of course.
