HECB SeriesModbus User GuideIntroductionThe HECB Series Modbus Guide provides information for using Neptronic communication feature. Thecommunication feature uses Modbus communication protocol over serial line in the RTU mode and provides aModbus network interface between client devices and Neptronic devices.The HECB Series Modbus Guide assumes that you are familiar with Modbus terminology.The following are the requirements for Modbus: Data Model. The Modbus server data model uses only the Holding Registers table. Function Codes. The Modbus server supports a limited function codes subset comprising: oRead Holding Registers (0x03)oWrite Multiple Registers (0x10)Exception Responses. The Modbus server supports the following exception codes:oIllegal functionoIllegal data addressoIllegal data valueSerial Line. The Modbus over serial line uses RTU transmission mode over a two-wire configuration RS485(EIA/TIA-485 standard) physical layer.oThe physical layer can use fixed baud rate selection or automatic baud rate detection (default) as per theNetwork Auto Baud Rate device menu item.oThe supported baud rates are 9600, 19200, 38400, and 57600.oThe physical layer also supports variable parity control and stop bit configuration.oParity control can be activated through the Network Parity device menu item.oStop bit configuration is modified through the Network Stop Bits menu item.oIn auto baud rate configuration, if the device detects only consecutive bad frames (2 or more) for one secondwith any given baud rate, it will reinitialize itself to the next baud rate.oIf the device does not detect any activity for one second or more, it will find a silent line to prevent a possiblebaud rate scan on the next frame it detects.Addressing. The device answers at the following two different addresses:oThe device's unique address (1 to 246) that can be set through the device menu or through holding registerindex 0.oThe permanent backdoor address for easy debugging. The backdoor for all devices is 247.www.neptronic.comPage 1
