LOGO! Base Module, 4 digital modules and 5 analog modules (example)
For LOGO! 12/24 RC/RCo, LOGO! 24/24o, LOGO! 24C/24Co modules, you can configure
whether the module uses two or four of the four possible analog inputs. AI inputs are
numbered consecutively depending on how many you configure the LOGO! Base Module to
use. If you configure two inputs, they are numbered AI1 and AI2, and correspond to the I7
and I8 input terminals. Subsequent AI expansions modules would begin numbering at AI3. If
you configure four inputs, they are numbered AI1, AI2, AI3, and AI4, and correspond to I7,
I8, I1, and I2 in that order. Subsequent AI expansions modules would begin numbering at
AI5. See topics "Constants and connectors - Co (Page 103)" and "Setting the number of AIs
in the LOGO! Basic (Page 225)".
