address
When the master is at write frame and the communication address of the slave is set to 0 (broadcast
communication address), all the slaves of the MODBUS will accept the frame without response.
Local communication address is unique in communication network and it is the foundation to achieve
point-to-point communication between the upper computer and VFD.
Note: The address of the slave cannot be set to 0.
