2 Intrductin The EVCB Series prvides infrmatin fr using Neptrnic cmmunicatin feature. The cntrller uses Mdbus cmmunicatin prtcl ver serial line in the RTU mde and prvides a Mdbus netwrk interface between client devices and Neptrnic EVCB Series devices. The EVCB Series Mdbus Guide assumes that yu are familiar with Mdbus terminlgy. The fllwing are the requirements fr Mdbus: Data Mdel. The EVCB Mdbus server data mdel uses nly the Hlding s table. Functin Cdes. The EVCB Mdbus server supprts a limited functin cdes subset cmprising: Read Hlding s (0x03) rite Single (0x06) rite Multiple s (0x10) Exceptin Respnses. The EVCB Mdbus server supprts the fllwing exceptin cdes: Illegal data address Illegal data value Slave device busy Serial Line. The EVCB 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 Mdbus Aut Baud Rate device menu item r hlding register index 1. The supprted baud rates are 9600, 19200, 38400, and The physical layer als supprts variable parity cntrl and stp bit cnfiguratin as per the Mdbus Cmprt Cnfig device menu item r hlding register index 2. 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. Addressing. The EVCB device nly answers at the fllwing address: The device's unique address (1 t 246) that can be set thrugh the device menu r thrugh hlding register index 0. Page 1
