Device setup

A Device represents a physical or logical source of data, such as a PLC, OPC-UA server, Modbus endpoint, SMB server, camera, or screen stream. Create the Device first, then create Data streams for tag/register/file values when the protocol supports them.

Add a device

1. Open /admin/core/device/.
2. Select Add device.
3. Enter a clear Name, such as Line 1 PLC or Press OPC-UA Server.
4. Select the Type. For PLCs, use PLC.
5. Select the Protocol.
6. Fill in Host, Port, and protocol-specific fields.
7. Set Poll interval if this device needs its own polling rate. Use 0 to use the system default.
8. Save the device.

Common fields

Field	Meaning
Name	Human-readable device name shown in lists and Data stream selection.
Type	Device category. Use PLC for OPC-UA, FEnet, MELSEC, and Modbus PLCs. Use Camera for V4L2 cameras and PC for VNC screen streams unless Reshenie gives a different value.
Protocol	Communication protocol used by the device.
Host	IP address, hostname, or serial port path depending on protocol.
Port	TCP port for network devices, or baudrate for Modbus RTU.
Manufacturer	Optional. For Modbus RTU, this can be used as a text encoding hint.
Module	Optional protocol-specific value. For MELSEC, use it for PLC type/module.
Poll interval	Polling interval in seconds. 0 uses the default interval.
Metadata	JSON hints for protocol options such as Modbus unit, byteorder, or wordorder.

OPC-UA

Use OPC-UA when the equipment exposes tags through an OPC-UA server.

Field	Value
Type	PLC
Protocol	OPC-UA
Host	OPC-UA server IP or hostname
Port	Usually 4840
OPC-UA discovery endpoint	Select or enter an endpoint suffix only when the server requires one
OPC-UA timestamp preference	Use the default unless Reshenie or the equipment vendor requires a specific timestamp

After saving, use the OPC-UA browser tool from the Device or Data admin page to find available nodes.

MELSEC

Use MELSEC for Mitsubishi PLC communication.

Field	Value
Type	PLC
Protocol	MELSEC
Host	PLC IP address
Port	Usually 5000
Module	PLC type/module, for example Q, when provided by Reshenie or the PLC vendor

Register examples for Data streams include D16000 and bit addresses such as M0.

FEnet

Use FEnet for compatible PLCs that expose FEnet register access.

Field	Value
Type	PLC
Protocol	FEnet
Host	PLC IP address
Port	Usually 2004

Register examples for Data streams include %MD100 for word/dword data and %MX1 for bit data.

Modbus TCP

Use Modbus TCP when the device is reachable over Ethernet.

Field	Value
Type	PLC
Protocol	Modbus
Host	Device IP address or hostname
Port	Usually 502
Metadata	Optional JSON, for example {"unit": 1, "byteorder": "big", "wordorder": "little"}

Modbus RTU

Use Modbus RTU when the device is connected through a serial adapter.

Field	Value
Type	PLC
Protocol	Modbus
Host	Serial port path such as /dev/ttyUSB0
Port	Baudrate, for example 9600
Manufacturer	Optional encoding hint, default utf-8
Metadata	Optional JSON, for example {"unit": 1, "parity": "N", "stopbits": 1, "bytesize": 8}

If the serial port does not appear, confirm the USB adapter is connected to the DataStone appliance and contact Reshenie support.

SMB

Use SMB when DataStone needs to read files from a Windows or SMB-compatible file server.

Field	Value
Type	PC or another appropriate category
Protocol	SMB
Host	SMB server IP address or hostname
Port	Usually 445
SMB auth protocol	Use Negotiate by default; use NTLM for legacy servers when required
Require signing	Keep enabled unless the server does not support signing

After saving the SMB device, use the SMB browser tool from the Data admin page to select file paths.

VNC

Use VNC when DataStone needs to stream a remote desktop or HMI screen. VNC is read-only streaming for now; do not configure it for keyboard, mouse, or write-back control unless Reshenie explicitly enables that in your deployment.

Field	Value
Type	Usually PC
Protocol	VNC
Host	VNC server IP address or hostname
Port	Usually 5900
Metadata	Required stream settings such as {"frame_width": 1280, "frame_height": 720, "frame_fps": 10}. Add "password": "<password>" only when the VNC server requires one.

After saving, verify that the stream opens in the viewing workflow provided by Reshenie. VNC devices usually do not need Data streams because the output is a visual stream, not a numeric tag or register.

V4L2

Use V4L2 for a camera connected directly to the DataStone appliance, such as a USB camera exposed by Linux as /dev/video0. V4L2 is read-only streaming for now.

Field	Value
Type	Camera
Protocol	V4L2
Host	Linux camera path, for example /dev/video0 or /dev/v4l/by-id/...
Port	Unused for V4L2 capture. Keep a non-negative value such as 0.
Metadata	Required stream settings, for example {"frame_width": 1280, "frame_height": 720, "frame_fps": 15}

If the camera path does not appear or the stream does not open, confirm the camera is connected to the DataStone appliance and ask Reshenie to check device permissions and supported camera modes.
