On the controller itself:
Your digital inputs are I:0/0 through I:0/19
Your digital outputs are O:0/0 through O:0/11
Your analog inputs are I:0.4, I:0.5, I:0.6 and I:0.7
Your analog outputs are O:0.4 and O:0.5.
On the expansion I/O:
Digital Inputs are I:1/0 to I:1/15, I:2/0 to I:2/15, I:3/0 to I:3/15 and I:7/0 to 7/7
Digital Outputs are O:4/0 to O:4/15, O:5/0 to O: 5/15 and O:6/0 to 6/15
Hope this helps.
