NOTE*1: The temperature sensor error is not supported by DVP06XA-S.
Note: Each error code corresponds to a bit (b0 ~ b11). Two or more errors may happen at the same time. 0 means there is an error, and 1 means there
is an error.
Example: If the digital input exceeds 4,000, the error K2 will occur. If the analog output exceeds 10V, the errors K2 and K32 will occur. (A/D does not
support displaying the error K2.)
#31 H’40E7 ○ R/W Communication address setting
RS-485 communication address.
Setting range is K1 ~ K254 and factory setting is K1.
#32 H’40E8 ○ R/W Communication format setting
For baud rate, the settings are 4,800 / 9,600 / 19,200 / 38,400 / 57,600 /
115,200 bps.
Communication format:
For DVP06XA-S:
ASCII：7,E,1 / 7,O,1 / 8,E,1 / 8,O,1 / 8,N,1

For DVP06XA-S2
ASCII：7,E,1 / 7,O,1 / 7,N,1 / 8,E,1 / 8,O,1 / 8,N,1 / 7,E,2 /
7,O,2 / 7,N,2 / 8,E,2 / 8,O,2 / 8,N,2
RTU ：8,E,1 / 8,O,1 / 8,N,1 / 8,E,2 / 8,O,2 / 8,N,2
Factory default : ASCII,9600,7,E,1 (CR#32=H’0002)

Reset to factory setting and set
characteristics adjustable priority
1. When b0=0, user can set OFFSET and GAIN value of CH1 (CR#18,
CR#24). When b0=1, inhibit user to adjust OFFSET and GAIN value of
CH1 (CR#18, CR#24).
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). (This feature does not supported by DVP06XA-S2, which
characteristic registers would remain as latched while using RS485.)
3. b2: Set to 1 and PLC will be reset to factory settings.
The setting of CH5 ~ CH6, give CH5 setting for example (b13, b12):
00: can be adjusted, latched. 01: can be adjusted, non-latched. (Not
supported by DVP06XA-S2, which registers would remain as latched.)
10: inhibit adjust. 11: reset to factory settings and clear b12, b13 to 0.
CR#33 is used to set the internal function priority. For example: characteristic register. Output latched function will save output setting in the internal
memory before power loss.
Display software version in hexadecimal. Example: H’010A=version 1.0A.
Symbols: ○ means latched. (Only valid when written in via RS-485 communication)

R means can read data by using FROM instruction or RS-485. W means can write data by using TO instruction or RS-485.

※ Added the RESET function for 06XA-S modules with firmware V4.14 or later and 06XA-S2 with firmware V4.16 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’40C8 ~ H’40EA of CR#0 ~ CR#34 will allow user to read/write data via RS-485 communication.
※ Function codes: 03’H is for reading data from registers. 06’H is for writing a word data into registers, while 10’H is for writing multiple word data.
※ 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’40C8” of CR#0 in hexadecimal format to decimal format, to have the
result 16584 and then adding one to it, you have 16585, the Modbus address in decimal format.
※ DVP06XA-S CR#32 communication format settings: for modules with firmware V4.12 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 V4.13 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 V4.13 or later.

※ DVP06XA-S2 CR#32 communication format settings: for modules with firmware V4.14 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

with firmware V4.15 or later.
