7.1.2.8.4 Example of Modbus communication commissioning
A PC is used as the host, an RS232-RS485 converter is used for signal conversion, and the
PC serial port used by the converter is COM1 (an RS232 port). The host controller
commissioning software is the serial port commissioning assistant Commix, which can be
downloaded from the Internet. Download a version that can automatically execute the
CRC check function. The following figure shows the interface of Commix.
First, set the serial port to COM1. Then, set the baud rate consistently with P14.01. The
data bits, check bits, and end bits must be set consistently with P14.02. If the RTU mode
is selected, you need to select the hexadecimal form Input HEX. To set the software to
automatically execute the CRC function, you need to select ModbusRTU
select CRC16 (MODBU SRTU), and set the start byte to 1. After the auto CRC check
function is enabled, do not enter CRC information in commands. Otherwise, command
errors may occur due to repeated CRC check.
The commissioning command to set the VFD whose address is 03H to be forward running
is as follows:
