2.1.2 Maximum setup with expansion and communication modules
LOGO! supports a maximum of 24 digital inputs, 8 analog inputs, 16 digital outputs, and 2
analog outputs (Page 13). You can achieve the maximum setup in different ways as shown
below:

For LOGO! 12/24RCE, 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 138)" and "Setting the
number of AIs in the LOGO! Basic (Page 299)".
