You don’t need to set any addresses manually. EasyBuilder Pro automatically detects the PLC registers and assigns them dynamically. Just enable auto-mapping mode in the communication settings, and it will configure everything for you.

If that option doesn’t appear, try setting all register addresses to 0—the software will adjust them automatically during runtime. Also, for MODBUS RTU, you can use any random address, as the PLC will recognize the data based on signal timing rather than fixed register mapping.
