8. CR#31 is used to set RS-485 communication address. The setting range is from 01 to 254. The
factory setting is K1.
9. CR#32 is used to set RS-485 communication baud rate: 4800, 9600, 19200, 38400, 57600, 115200
bps, b0: 4800bps, b1: 9600bps, (factory setting) b2: 19200bps, b3: 38400 bps, b4: 57600 bps, b5:
115200 bps, b6-b13: reserved, b14: exchange low and high byte of CRC check code. (only for RTU
mode) b15=0: ASCII mode, =1: RTU mode.
10.	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.
11.	CR#34 is software version of model type.
12.	CR#35~ CR#48 are used for system.

1.When power is on, POWER LED will be lit and ERROR LED will be lit for 0.5 second.

2.Normal run: POWER LED should be lit and ERROR LED should turn off. When power supply is lower than 19.5V, ERROR LED will blink continuously till the power supply is higher than 19.5V.

3.When it connects to PLC MPU in series, RUN LED on MPU will be lit and A/D LED or D/A LED should blink.

4.After receiving the first RS-485 command during controlling by RS-485, A/D LED or D/A LED should blink.

5.After converting, ERROR LED should blink if input or output exceeds upper bound or below the

lower bound. Program example:

Explanation:

Reading the data of model type from expansion module K1 and check to see if the data is H49 (DVP-02DA-S model type).

D100 will increase K1 and D101 will increase K5 every second. When value of D100 and D101 attain to K4000, they will be reset to 0.

For DVP-02DA-S model, M1 will be on and set the output mode: CH1 mode to 0, CH2 mode to 2. Writing output setting CR#10 and CR#11 to D100 and D101. Analog output will vary with D100 and D101 value.

Footnote	The rules for adding multiple special modules to a Main Processing Unit:
	m1: The maximum number of special modules attached to an MPU is 8. The
	order of module closest to the MPU is 0, and the module furthest from the
	MPU is 7.
	m2: The number of Controlled Registers (CR) built in is 49. (#0~#48).
	FROM/TO command read/write 16-bit CR data in one command, while
	DFROM/DTO command to read/write 32-bit CR data in one command.

The charts above are D/A conversion characteristic curve of voltage input mode and current input mode. Users can adjust conversion characteristic curve by changing OFFSET values (CR#22~CR#23) and GAIN values (CR#28~CR#29) depend on application.

LSB (Least Significant Bit): 1.voltage input: 1LSB=10V/8000=2.5mV. 2.current input: 1LSB=20mA/4000=5µA.

Please refer the footnote below for calculation of the special module number.

In ES series models, flag M1083 is not provided. When FROM/TO command is executed, all interrupts (including external or internal interrupt subroutines) will be disabled. All interrupts will be executed after FROM/TO command is completed. Besides, FROM/TO command also can be executed in the interrupt subroutine.

The function of the flag M1083 (FROM/TO mode exchange) provided in EP/EH series models:

1.When M1083=Off, all interrupts (including external or internal interrupt subroutines) will be disabled when FROM/TO command is executed. The Interrupts will resumed after FROM/TO command complete. Please be advised FROM/TO command can be executed in the interrupt subroutine.

2.When M1083=On, if an interrupt enable occurs while FROM/TO command are executing, the interrupt FROM/TO command will be blocked till the requested interrupt finish. Unlike M1080 off situation, FROM/TO command cannot be executed in the interrupt subroutine.
