MPAS
ModBus is compatible with previous
device switch
1. Write command with parameters, such as
MPAS1;
2. Parameter 0 indicates incompatibility
(default), and parameter non-0 indicates
compatibility;
3. It is compatible with the numerical data
type in Modbus protocol of previous models,
and the string data type is not compatible with
the device except the serial number;
4. The settings will be saved;
5. Return "set error" when setting error, return
"memory error" when storage error, and
