5 Register List :
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.
For details, please refer to the communication manual.
・
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 )
・
Representation of function name
This document has prioritized the use of common names so far. However, GXE unique name is used in the register list.
The correspondence is as follows and the meaning is the same.

Alarm History
0 (0x0000)
1
Indicates protection content that occurred.
Indicates that overtemperature
protection has been activated.
Indicates that the booster output
inside the power supply has decreased.
Reserved bit
(Alarm is not allocated)
Indicates that the power supply
is remote off
Indicates that an error occurred
inside the power supply.
Alarm is not allocated because
it is a reserved bit.
Please contact us when the SYSTEM error occurs.
