Modicon 170ARM37030 w/ M1 Ethernet

I've programmed other brands of PLCs but I'm a newby at Modicon. Can anyone shed some light or point me in the right direction on how the addressing for
your symbols relate to the I/O terminals? I'm using proworx32 by the way. Most of the plcs I've worked with use X or Y, or at least have a table where you can assign inputs and outputs. I can't seem to find a good beginner resource on modicon. I know this should be simple stuff but I just need a few examples. I've tried modicon.com (Telemecanique)
Thanks!

I've only used PL7 for programming Modicon PLC's. On that the Inputs are %I1.0 etc and the outputs are %Q1.0 etc.
sQuick..

I'm using Proworx NxT instead of Proworx 32 since that's what our only Modicon client has from the previous system integrator. Modicon has four types of memory addresses: - Both internal and output coils are addressed as 0xxxxx, starting at 000001. - Discrete inputs are addressed as 1xxxxx, starting at 100001. - Input registers are addressed as 3xxxxx, starting at 300001. - Internal and output registers are addressed as 4xxxxx, starting at 400001.
Some older models only supported 5 digit addressing instead of 6 digits, and Proworx further allows you to select 5 or 6 digit addressing if your processor supports 6 digits. Furthermore, the communications driver for your HMI software or OPC server probably uses 6 digit addressing only. Don't worry, they the equivalent 5 and 6 digit addresses, such as 41728 and 401728, refer to the same memory location.
The I/O modules are configured using the Traffic Cop, wherever it might be found now. By the way, bits within words are numbered left to right, 1 (MSB) to 16 (LSB).
My considered opinion on NxT, to paraphrase Will Smith in "Men in Black": "Unlimited technology from the whole universe, and we program our PLCs with Proworx PoS!"
