Modbus main machine sending selections

Set the data that inverter sent the slave machines when inverter is main machine.All slaves will receive the command
from the host when the main machine sends broadcast commands.
The host can send four polling data, corresponding to the settings of LED "0" digit, "00" digit,"000" digit and "0000"
digit. No data is transmitted when invalid.
LED "0" digit: 1st group of frame selection
0: Invalid
1: Main machine run command
2: Main machine given frequency
3: Main machine output frequency
4: Main machine upper limit frequency
5: Main machine given torque
6: Main machine output torque
7: Reserved
8: Reserved
9: Main machine given PID
A: Main machine feedback PID
B: Reserved
C: active current component
LED "00" digit: 2nd group of frame selection as above
LED "000" digit: 3rd group of frame selection as above
LED "0000" digit: 4th group of frame selection as above
Host broadcast data Corresponding address and application accepted by Slaver

0x01:FWD run
0x02:REV run
0x03:FWD jog
0x04:REV jog
0x05:Stop command (Slave machine stops according stop mode)
2: Main machine given frequency 0x3000, can be used as communication given frequency
