1) Register Details
This is the configuration register for slave ID.
According to the MODBUS specification, the slave ID is specified as integer data in the range from 1 to 247.
In order to avoid misconfiguration, setting update by broadcast is ignored in only this register.
Configuration data is retained even when input is cut off.

*An exception response (Exception code: 0x03) is returned when writing values outside the range.
GXEs connected to communication line must have a unique slave ID.
Before connect to communication line, set each GXE so that the slave ID does not overlap.
This register is used for opening the communication port when the power supply starts up, and is not referred to during
operation.
Even after updating the register setting value, the transmission and reception of the query/response is performed by the
configuration at the time of startup.
As an exception, when communication reinitialization of the diagnostic query (FC : 0x08 / SC : 0x0001) is accepted, the
updated configuration is applied because the communication port is reopened.
When AC input is turned on with the communication setting switch set to invalid (DIS), the value of this register is not
referred and communication is performed with the default value.
