1) Register Details
This is the configuration register for transmission code (parity bit / stop bit).
Specify the set value with integer data in the range of the table below.
Configuration data is retained even when input is cut off.

*An exception response (Exception code: 0x03) is returned when writing values outside the range.
The meanings of register setting values are shown below.
The character transmission length of the MODBUS protocol consists of eleven bits of [1 start bit + 8 data bits + 1 parity bit + 1
stop bit], in the case of no parity it is 2 stop bits and the transmission length 11 bits are maintain.
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.
