4. GXE MODBUS Register
In GXE, Input Register and Holding Register of 16-bit data are used in the data model specified by MODBUS protocol.
Discrete Register and Coil Register of 1 bit data are not used.
The register address of GXE in this communication manual is indicated by the PDU address.
If a register that does not exist is used as the starting address, it becomes an exception response.
・Numerical notation
Numbers starting with '0x' indicate hexadecimal numbers. (Example : 0x0400 = 1024d)
Decimal numbers are indicated by appending 'd' after the value or without adding anything. (Example : 1024d , 1024)
Binary numbers are indicated by appending '0b' before the value. (Example : 0b0100 0000 0000 = 1024d)
The internal data type of GXE is 16 bit little endian. ( LSB: bit 0 / MSB: bit 15 )
4.1 Input Register List
Input Registers are read-only 16-bit data registers.
Mainly, Input Registers has measurement data.
Broadcast is invalid.
Data read is possible with function code: 0x04.
