Hi,
My question is whether MIO ports on U6 can be used as regular port? if so, with low level function, should MIO be referenced as 20-22? The low level functions in U6 manual only mentions 0-19 for FIO, EIO and CIO but not MIO. Thanks.

We looked closer at the firmware and the documentation was correct. 20-22 are not supported in the low-level bit or port functions. The reason is that they are shared with CIO0-CIO2, so to read/write them you use channel numbers 16-18.
Need to look at the UD to see if it just passes through to low-level or if it supports 20-22.
The UD driver passes through to low-level and does not support digital I/O lines 20-22 if the firmware doesn't.
