Setting the number of AIs in the LOGO! Basic 
LOGO! 12/24RC/RCo/RCE, LOGO! 24/24o and LOGO! 24C/24Co support up to four 
onboard inputs that can be used as either digital or analog inputs (0 ...10V). Inputs I7 (AI1) 
and I8 (AI2) are available as analog inputs by default, whether you use them or not. Inputs I1 
(AI3) and I2 (AI4) are optional analog inputs. A LOGO! Basic provides a menu where you 
can choose to use two analog inputs (the default, AI1 and AI2), or four. Regardless of the 
settings, inputs I1 and I2 can be used as digital inputs. To use them as analog inputs AI3 
and AI4, you must set the 'BM AI NUM' to four. Note that the number of configured analog 
inputs on the LOGO! Basic affects the subsequent numbering of analog inputs on attached 
expansion modules (See the "Maximum setup (Page 34)" topic). 
You can set the number of AIs in programming mode only.
