Only these 3 types of expansion module don’t support DIP dial switch: 16-points digital module, 4-pointsanalog module and temperature module. The dial switch on expansion module can be used for addressing. If a module has external dial switch, then the user can set the address by configuring it (Address range for 4 bit dial switch is 1~15). As to those modules without external dials witch,the user can set the address only by programming software.
