Communication Description:
Due
to precision and data requirements, the registers here use
floating-point types. (Floating-point data is 32 bits, which takes up
four bytes altogether)
According to the ModBus-RTU protocol, each
terminal has an address, which is modified by the 06 function code of
modbus-RTU. The default address is 1, and the modified address range is
1~247, where 0xfa is the general query address (read unknown address
data), modify unknown address data, bear in mind that this address can
only be used in a single operation, forbid online reading data and
modifying address).
Package List:
-1 x Current Detection Module
-10 x Transformer
Note:
The RS485 communication line must not be connected to VCC and GND.
Although RS485 can shield the instantaneous high voltage electromotive
force, if the A+ and B- sections of RS485 are misconnected to VCC and
GND, the 485 chip will be burned! Please connect first, and then check
the connection is correct, and then power the module.
