Page 278 Goodrive270 series VFD for fan and pump Communication According to the requirements of the RS485 industrial bus standards, all the devices need to be Figure 9-2. Figure 9-3 is the simplified wiring diagram, and Figure 9-4 is the practical application diagram.
Page 279: Rtu Mode
Goodrive270 series VFD for fan and pump Communication Figure 9 5 Star connection Use shielded cables, if possible, in multi-device connection. The baud rates, data bit check settings, and other basic parameters of all the devices on the RS485 line must be set consistently, and addresses cannot be repeated.
Page 280 Goodrive270 series VFD for fan and pump Communication In RTU mode, the transmission of a new frame always starts from an idle time (the transmission time of 3.5 bytes). On a network where the transmission rate is calculated based on the baud rate, the transmission time of 3.5 bytes can be easily obtained.
Page 281 Goodrive270 series VFD for fan and pump Communication response may cause severe problems. Therefore, the data must be checked. The check is implemented as follows: The transmitter calculates the to-be-transmitted data based on a specific algorithm to obtain a result, adds the result to the rear of the message, and transmits them together.
Page 282: Rtu Command Code And Communication Data
Goodrive270 series VFD for fan and pump Communication bit (8th bit) is detected and processed, the XOR operation is performed on the next 8-bit byte and the current content in the register. The final values in the register are the CRC values obtained after operations are performed on all the bytes in the frame.
Page 283 Goodrive270 series VFD for fan and pump Communication For example, if the master reads two contiguous pieces of data (that is, to read content from the data addresses 0004H and 0005H) from the VFD whose address is 01H, the frame structures are described in the following.
