Select [Tools] - [Data Server Editor] to open the [Data Server Editor] window. With this window open, press the icon and select [Add Serial Device]. This will bring up another small window where the user can assign a [Device Name] and [Device Type].
Users are currently only able to select [MODBUS_RTU_SLAVE] for the [Device Type] field. After pressing the [OK] button, the user will be presented with another window that displays the communication parameters for the Modbus server.
Item | Description |
Device Name | Allows the user to assign a name for the I/O Device. |
Device Protocol | Select the type of target device. This also selects the driver used to communicate with the device. |
Time Out | The timeout feature periodically checks whether the connection is still valid. If a requested frame is not received in the assigned time, it will be processed as a communication failure. This option is not applied if the protocol is TCP/IP. Values represent multiples of 100ms. For example, a value of 10 represents 1000ms or 1 second. |
Retry Count | Assign the number of communication retry attempts after a communication failure. |
Serial Port | Assigns the local (Xpanel) COM port to use Modbus RTU Slave. |
Baudrate | Configures the baud rate (300bps ~ 256,000bps). |
Parity | Determines whether to use an even, odd, or no parity bit for error checking. |
Data Bits | Determines the number of data bits per packet. You can select between 5 and 8 bits. If the data contains Korean characters, please select 8 bits to avoid errors. |
Flow Control | Allows the user to enable or disable flow control. With this option enabled, the MODBUS Master will wait for an acknowledgement signal from the target device before sending another command. |
Stop Bits | Determines the number of stop bits between frames. |
Comm Type | Allows the user to select from RS232, RS422, and RS485 communication types. |
Unit ID | Allows the user to set the Modbus Address of the slave. |
