On the front of the module, there is a rotary switch labeled ID, that is used to select the Modbus slave address for the module. When installing multiple modules of the same type, the ID for each module should be unique.
Rotary switch position 0 corresponds to Modbus slave address 10. If the ID is changed after the module is powered on, it must be power cycled for the new ID to take effect.
