    The serial communication port RS485 is available on the Command Terminals and on the 9pin DIN male connector. On this port may be done a network up to 127 CD3000E. On the 9pin DIN male connector is also possible connect the CD-EASY (see par. Errore. L'origine riferimento non è...

  • Page 3: Modbus Communication

    2 MODBUS communication The serial communication port of the thyristor unit is two-wire RS485 type. This port use an half-duplex system. When a Unit must transmit active the transmission line, and when there are not units in transmission the outputs are fixed to high impedance. The serial communication port allows to communicate between the thyristor units and a MASTER device (ex.

  • Page 5: Read Holding Registers

    2.3 Read Holding Registers This function reads the instantaneous value of only one specified number of parameter from an address. The message is composed by 8 Byte: one Byte is for the address, one for the function (03 Hex), two Byte for the first parameter to read, two Byte for the total number of parameters to read that fixed to 1 (0001 Hex), and finally two Byte for the CRC: Address Address of the First...
