Which registers hold the TMC2 analog cartridge status information in an M221 controller?

Issue
Which registers hold the TMC2 analog cartridge status information in an M221 controller?

Product Line
Modicon M221

Environment
EcoStruxure Machine Expert Basic / SoMachine Basic - PLC configuration software

Resolution
The status/diagnostic information for TMC2 analog cartridges is held in one dedicated address per channel.
For inputs, the syntax is: %IWS0.x0y
For outputs, the syntax is: %QWS0.x0y
where x is the cartridge number, and y is the channel number in the cartridge.

For example if we have a TM221C40T (which can physically accommodate two cartridges) with TMC2AI2 and TMC2AQ2C modules, there are 4 addresses containing the statuses of each of the 4 channels:

First cartridge (TMC2AI2 - analog input):
%IWS0.100: first cartridge, channel 1
%IWS0.101: first cartridge, channel 2

Second cartridge (TMC2AQ2C - current analog output)
%QWS0.200: second cartridge, channel 1
%QWS0.201: second cartridge, channel 2
