Software Configuration
For SM231 8AI×TC Input module, readings were saved in VW more than AIW, the specific address depends on module location, calculated as following:
x(VWx) = Slot no. × 64 + Input channel no.× 2
Slot number corresponding with installation location, and the slot 0 is the first expansion module nearest to CPU, then the second is slot 1, and so on. There are all 8 Input channels from A to H and numbered as 0 to 7.
Based on the above equation, there is the address look-up table.
