Address Setting for Expansion Modules
When multiple expansion modules are connected to one single CPU PLC, each expansion module must be assigned a distinct station address.
Factory default expansion address: 1. The expansion address is configured via DIP switch. The corresponding relationship between expansion address number and DIP switch status is shown below:
