6.1 Programmable Terminals — Specifications
You can program terminals C1 – C4 and U1 – U12 for analog, pulse, or digital
I/O functions. With certain restrictions, you can mix terminals programmed for
the analog function with terminals configured for the pulse count and digital I/O
functions.
Each odd numbered U and C terminal is paired with the even numbered terminal
next in the series, for example U1 / U2 and C1 / C2 . If one of a pair is configured
for a function (analog input, digital I/O, etc.) or logic level (3.3 or 5 V), the paired
terminal must be used in the same function and at the same logic level.
