Push-button addressing Display current address (digits in reverse order) The Modbus address can be set without a separate tool by using the push-button and LED. To display the current address, press button <1s. Colors 1-digits: red 10-digits: green 100-digits: orange Example for address 124: LED Note The address is entered and shown in reverse order. Set new address (digits in reverse order) 1. Enter addressing mode: press button > 1s until LED shines red, then release button (before LED gets dark). 2.
