neptronic EVCB14N Series Modbus Communication Module
Introduction
The EVCB14N Series Modbus Communication Module User Guide provides information
for using the Neptronic® communication feature. The controller uses Modbus
communication protocol over serial line in the RTU mode and provides a Modbus
network interface between client devices and Neptronic EVCB14N Series devices.
The EVCB14N Series Modbus Guide assumes that you are familiar with Modbus
terminology.
The following are the requirements for Modbus:
- Data Model. The EVCB Modbus server data model uses only the Holding Registers table.
- Function Codes. The EVCB Modbus server supports a limited function codes subset comprising:
- Read Holding Registers (0x03)
- Write Single Register (0x06)
- Write Multiple Registers (0x10)
- Exception Responses. The EVCB Modbus server supports the following exception codes:
- Illegal data address
- Illegal data value
- Slave device busy
- Serial Line. The EVCB Modbus over serial line uses RTU transmission mode over a two-wire configuration RS485 (EIA/TIA-485 standard) physical layer.
- The physical layer can use fixed baud rate selection or automatic baud rate detection (default) as per the Modbus Auto Baud Rate device menu item or holding register index 1.
- The supported baud rates are 9600, 19200, 38400, and 57600.
- The physical layer also supports variable parity control and stop bit configuration as per the Modbus Comport Config device menu item or holding register index 2.
- In auto baud rate configuration, if the device detects only consecutive bad frames (2 or more) for one second with any given baud rate, it will reinitialize itself to the next baud rate.
- Addressing. The EVCB device only answers at the following address:
- The device’s unique address (1 to 246) that can be set through the device menu or through holding register index 0.
