In the iSMA Module kit there are available two types of components to read/write digital outputs:
- DO: reads/writes individual digital outputs (output number is selected in component property sheet);
- DO_ALL: reads all digital outputs using one register.
Note: DO_ALL component has 12 input slots (DO component - up to 12 outputs), which correspond to the largest module iSMA-B-MIX38. Using module with a smaller output number makes the surplus outputs inactive.
