  • Page 17: Coil Status Registers (0X Register)

    Modbus Register Map Organization Coil Status Registers (0X register) The Coil Status register block allows the Modbus master to scan • command outputs through the output relays of the devices (external commands), • manipulation of taggings (internal commands) that can be changed using Modbus. Furthermore, these registers can be used to execute switching operations and internal commands.
