An ethernet device and a serial device are the two I/O devices a user could set up.

Communication Between Xpanel and other devices

1. Click Tools > I/O Device Editor > click the + icon to begin I/O device configuration for Connection Type, Device Name, and Device Type > click Ok.

   

Please note that Canvas can still communicate with these devices via Modbus if the specific protocol necessary for a given device is unavailable. For more information on a specific device type, refer to the Communication Drivers section.

General Communication Configuration

General configuration will appear regardless of the selected Connection Type and Device Type.

Item	Description
Device Name	Allows the user to assign a name for the selected I/O device.
Device Protocol	Allows the user to select a protocol for a device.
Timeout (ms)	The maximum time to wait with no response before assuming a communication failure.
Retry Count	Set the number of retries for sending a frame when communication fails.
Swap 16 (16-bit Data Swap)	This option swaps bytes for all word or double-word-sized data. The following diagram shows an example of byte-swapping: Almost all data types will be influenced by this option except INT16 / UINT16
Swap 32 (32-bit Data Swap)	This option swaps words of all double-word-sized data. The following diagram shows an example of word swapping: Tag values with data types INT32 / UINT32 / BCD32 / UBDC32 / FLOAT will be influenced by this option.
Swap String	Swaps the upper and lower bytes of string word data.
String Encoding	Specifies the encoding method for reading and writing string values stored on the device. This option can be overridden for individual tags in the Edit Tag menu.
String Encoding Method	When an invalid character is encountered, the gateway will do one of the following: Replace the character with "?". Skip the character and continue with the next one. Stop the string and truncate any remaining characters. This option can be overridden for individual tags in the Edit Tag menu.

Ethernet Communication Configuration

The Ethernet section shown below will appear in the same After selecting [Ethernet Device] on the [Add New I/O Device] window, the [I/O Device Editor] will display the [Ethernet] tab.

1. Ethernet Settings

IPv4 Address: Type the IP address of the device.

Ethernet Type: Select UDP or TCP.

Port: Enter the port number of the target I/O device.

※ For information on the pinout configuration for Serial and Ethernet, go to the Communication Port Pinouts manual.

Serial Communication Configuration

After selecting [Serial Device] on the [Add New I/O Device] window, the [I/O Device Editor] will display the [Serial] tab.

1. Serial Settings

Serial Port: Select a serial communication port for the Xpanel. The port will vary depending on the Xpanel model. See the below table for more information

Baud Rate: 300-115200 bps is supported.

Parity: Select the same parity (None, Even, Odd) as the device.

Data Bits: Select the same data bit setting (5 Bits, 6 Bits, 7 Bits, 8 Bits) as the device.

Flow Control: Allows the user to

Stop Bit(s): Select the same stop bit setting (1 Bit or 2 Bit) as the device.

Station Number: Enter the station number of the target device.

2. Station Settings

Move to the [Station] tab of the [I/O Device Editor] window, and configure the proper parameters.

Station Name: Enter the station name for the I/O device.

Station ID: Set the station ID. It must match the target device’s station ID.

Ethernet Communication Configuration

After selecting [Ethernet Device] on the [Add New I/O Device] window, the [I/O Device Editor] will display the [Ethernet] tab.

1. Ethernet Settings

IPv4 Address: Type the IP address of the device.

Ethernet Type: Select UDP or TCP.

Port: Enter the port number of the target I/O device.

※ For information on the pinout configuration for Serial and Ethernet, go to the Communication Port Pinouts manual.
