  • Page 11: Bus Specific Parameters

    Bus specific parameters Bus specific parameters The following settings for the serial communication between the Modbus master and the Modbus slave of the SIPROTEC device have to be defined when programming the device using the parameterization system DIGSI. Permissible slave addresses are in the range between 1 and 247. Slave address The Modbus slave of the SIPROTEC device supports the two serial Modbus mode...
  • Page 12 Bus specific parameters Processing of If one of the Modbus messages "Force Single Coil", "Preset Single Register", "Force Multiple Coil" or "Preset Single Regs" (ref. to chap. 2) broadcast is transmitted from the Modbus master to the Modbus slaves using slave messages address 0 all Modbus slaves recognize this message as a broadcast message and process it.
