2.1. DI input
2.1.1. Electrical level detection
➢ Register address range: 32~39(0x0020~0x0027)
➢ Supported function code: 02(Read discrete input), 03(Read holding register)
➢ Connection: Default is dry contact input. Short-circuit DI and COM will change input status. If user needs wet
contact input can contact to our sales personnel
➢ Electrical level detection: Default status is 0, after short-circuiting DI and COM, status will be 1. Detection
method: 02 function code of Modbus protocol.
Example:
Detect input of the first way, send: 11 02 00 20 00 01 BA 90
Short-circuiting will return: 11 02 01 01 64 88
No short-circuiting will return: 11 02 01 00 A5 48
2.1.2. Buttons detection
➢ Register address range: 48~55(0x0030~0x0037)
➢ Supported function code: 03(Read holding register), 04(Read input register)
➢ Connection: Default is dry contact input. Short-circuit DI and COM will change input status. If user needs wet
contact input can contact to our sales personnel
➢ Electrical level detection: Default status is 0000, after short-circuiting DI and COM and then releasing, status
will be FF00. Detection method: Read button register value by 03 function code of Modbus protocol. After
reading once button register, status will recover to 0000; after executing conditional control, status will
recover to 0000. too.
Example:
Detect the first way button, send: 11 03 00 30 00 01 86 95
USR-IO808-EWR User Manual Technical Support: h.usriot.com

No button will return: 11 03 02 00 00 79 87
Have button will return: 11 03 02 FF 00 38 77
2.1.3. Pulse counting
➢ Register address range: 64~71(0x0040~0x0047)
➢ Supported function code: 03(Read holding register), 04(Read input register)
➢ Connection: Default is dry contact input. Short-circuit DI and COM will change input status. If user needs wet
contact input can contact to our sales personnel
➢ Pulse counting: Default status is 0, short-circuit DI and COM and then release will count 1. Detection method:
Read pulse counting register value by 03 function code of Modbus protocol. Maximum value of pulse counting
is 65535 and it will restart counting after exceeding 65535. Can’t reset count to 0 and restart product won’t
save count.
➢ Note: Pulse counting won’t filter input waveform and all pulse in the range of detection will be recorded. So
input waveform should keep stable to ensure accurate count.
Example:
Detect count of the first way, send: 11 03 00 40 00 01 87 4E
Return: 11 03 02 00 00 79 87

➢ Supported function code: 01(Read coil), 05(Write single coil), 0F(Write multiple coil)
➢ Connection: DO output is Relay passive output. Don’t power the coil, Relay COM and NC will close, COM and
NO will open. After powering, the contrary is the case.
Take the first way Relay control as example:
Query: 11 01 00 00 00 04 3F 59
Control to close: 11 05 00 00 FF 00 8E AA
Control to disconnect: 11 05 00 00 00 00 CF 5A

➢ Output action(Relay output)
1: Disconnect
2: Close
3: Reversal
➢ Condition
1: Forward direction output follow
2: Backward direction output follow
255: Button action
➢ Control mode
Switching value control: DI input control DO output directly
Semaphore control: DI button semaphore control DO. Press button once, DO act once(Execute action in rising
edge of releasing button).
Detailed explanation:
1. Forward direction output follow
Enable forward direction output follow: Set condition register to 1, input register is corresponding to one way
register address of 8-way input and output register is corresponding to one way register address of 8-way output.
For example, if configure as 0x20 0x00 0x01 0x01 0x00 0x00 0x00 0x00, it represents status of DO1 will follow
status of DI1 which means DO1 will close if DI1 close and DO1 will disconnect if DI1 disconnect.
2. Backward direction output follow
Enable backward direction output follow: Set condition register to 2, input register is corresponding to one way
register address of 8-way input and output register is corresponding to one way register address of 8-way output.
USR-IO808-EWR User Manual Technical Support: h.usriot.com
Jinan USR IOT Technology Limited www.usriot.com
18
For example, if configure as 0x20 0x00 0x01 0x02 0x00 0x00 0x00 0x00, it represents status of DO1 will be
opposite as status of DI1 which means DO1 will close if DI1 disconnect and DO1 will disconnect if DI1 close.
3. Button control
Enable button control: Set condition register to 255, input register is DI button register and output register is DO
output register. Action can be 1(disconnect ), 2(close), 3(reversal ), threshold register and reserved register can’t
work.
For example, if configure as 0x30 0x00 0x03 0xFF 0x00 0x00 0x00 0x00, it represents detecting DI1 button once
will reverse status of DO1 once.
Note:
Input register is 0 means close this conditional control and execute button action once will clear button register. If
multiple conditions will lead to paradoxical result, program will execute two results quickly. If forward direction
output follow and backward direction output follow lead to paradoxical result, disconnecting and closing will
revolve.
2.7.3. Connect to remote server
User can modify related register parameters of remote server to realize IO808-EWR connecting to remote server.
Procedure as follow:
1. Power the IO808-EWR and connect IO808-EWR’s RS485 interface to PC. Run setup software(User can refer to
1.4.1.Control by serial), modify remote server address and remote port as follow:
Figure 25 Configure remote server parameters
2. Restart IO808-EWR to make configuration take effect.
3. Login remote server and open the port.
4. Wait IO808-EWR LED ‘NET’ light which means IO808-EWR connect to remote server successfully, Then user
can transmit Modbus TCP/RTU command from server side to control IO808-EWR and receive response from
IO808-EWR.
2.7.4. Reset to default by hardware
USR-IO808-EWR User Manual Technical Support: h.usriot.com
