CR#33 is used to set the internal function priority. For example: characteristic register. Output latched function will save
output setting to the internal memory before power loss.

Symbols: ○ means latched. (Only valid when written in via RS-485 communication)
╳ means not latched.
R means can read data by using FROM instruction via RS-485.
W means can write data by using TO instruction via RS-485.
LSB (Least Significant Bit): 1. Voltage output: 1
※ Added the RESET function for modules with firmware V4.06 or later. Connect the module power input to 24 VDC and
write H'4352 into CR#0 and then turn the power off and on again; all parameters in modules, including communication
parameters are restored to factory defaults.
※ The corresponding parameters address H'4032 ~ H'4054 of CR#0 ~ CR#34 are provided for users to read/ write data
via RS-485 communication.
※ If you want to use Modbus address in decimal format, you can transfer a hexadecimal register to decimal format and
then add one to have it become a decimal Modbus register address. For example transferring the address "H'4032" of
CR#0 in hexadecimal format to decimal format, to have the result 16434 and then adding one to it, you have 16435, the
Modbus address in decimal format.
※ Function codes: 03'H is for reading data from registers. 06'H is for writing a word data into registers. 10'H is for writing
multiple word data into registers.
※ CR#32 communication format settings: for modules with firmware V4.04 or previous versions, b11~b8 data format
selection is not available. For ASCII mode, the format is fixed to 7, E, 1 (H'00XX) and for RTU mode, the format is fixed
to 8, E, 1 (H'C0xx/H'80xx). For modules with firmware V4.05 or later, refer to the following table for setups. Note that
the original code H'C0XX/H'80XX will be seen as RTU, 8, E, 1 for modules with firmware V4.05 or later.

It is used to set communication format.
For baud rate, the settings are
4,800/9,600/19,200/38,400/57,600/115,200 bps.
Communication format:
ASCII：7,E,1 / 7,O,1 / 8,E,1 / 8,O,1 / 8,N,1
RTU ：8,E,1 / 8,O,1 / 8,N,1
Factory default : ASCII,9600,7,E,1 (CR#32=H'0002)
Refer to ※CR#32 communication format settings at the end
of this table for more information.
Reserved
Output latched setting, default setting H'0000.
Give CH1 setting for example:
1. When b0=0, user can set OFFSET and GAIN value of CH1
(CR#22, CR#28). When b1=1, inhibit user to adjust
OFFSET and GAIN value of CH1 (CR#22, CR#28).
2. The value of b1 determines whether a characteristic
register is latched while using RS485 to read-write control
registers. b1=0 (latched), b1=1 (not latched).
3. When b2 is set to 1, all settings will be reset to default
setting.
In hexadecimal to display software version.
For example: H'010A means 1.0A.
