LSIS G100 - 7.3 Communication Protocol

7.2.8 Parameter Group for Data Transmission
By defining a parameter group for data transmission, the communication addresses
registered in the communication function group (CM) can be used in communication.
Parameter group for data transmission may be defined to transmit multiple
parameters at once, into the communication frame.

Note
When registering control parameters, register the operation speed (0h0005, 0h0380,
0h0381) and operation command (0h0006, 0h0382) parameters at the end of a parameter
control frame. The operation speed and operation command must be registered to the
highest number of the parameter control-h (Para Control-h).
For example, when the Para Ctrl Num is 5, register the operation speed to Para Control-4
and the operation command to Para Control-5.
7.3 Communication Protocol
The built-in RS-485 communication supports LS INV 485 and Modbus-RTU protocols.
7.3.1 LS INV 485 Protocol
The slave device (inverter) responds to read and write requests from the master
device (PLC or PC). The basic types of protocol are as below.
