3 Intrductin HECB Series Mdbus User Guide The HECB Series Mdbus Guide prvides infrmatin fr using Neptrnic cmmunicatin feature. The cmmunicatin feature uses Mdbus cmmunicatin prtcl ver serial line in the RTU mde and prvides a Mdbus netwrk interface between client devices and Neptrnic devices. The HECB Series Mdbus Guide assumes that yu are familiar with Mdbus terminlgy. The fllwing are the requirements fr Mdbus: Data Mdel. The Mdbus server data mdel uses nly the Hlding s table. Functin Cdes. The Mdbus server supprts a limited functin cdes subset cmprising: Read Hlding s (0x03) Write Multiple s (0x10) Exceptin Respnses. The Mdbus server supprts the fllwing exceptin cdes: Illegal functin Illegal data address Illegal data value Serial Line. The Mdbus ver serial line uses RTU transmissin mde ver a tw-wire cnfiguratin RS485 (EIA/TIA-485 standard) physical layer. The physical layer can use fixed baud rate selectin r autmatic baud rate detectin (default) as per the Netwrk Aut Baud Rate device menu item. The supprted baud rates are 9600, 19200, 38400, and The physical layer als supprts variable parity cntrl and stp bit cnfiguratin. Parity cntrl can be activated thrugh the Netwrk Parity device menu item. Stp bit cnfiguratin is mdified thrugh the Netwrk Stp Bits menu item. In aut baud rate cnfiguratin, if the device detects nly cnsecutive bad frames (2 r mre) fr ne secnd with any given baud rate, it will reinitialize itself t the next baud rate. If the device des nt detect any activity fr ne secnd r mre, it will find a silent line t prevent a pssible baud rate scan n the next frame it detects. Addressing. The device answers at the fllwing tw different addresses: The device's unique address (1 t 246) that can be set thrugh the device menu r thrugh hlding register index 0. The permanent backdr address fr easy debugging. The backdr fr all devices is Page 1
