In this window, select the ‘MODBUS TCP’ as the ‘Device type’ and configure the proper Ethernet communication parameters. Ensure that those parameters are matched with the device’s configuration. See the Communication Configuration section for more information.

Create a station

Move to the [Station] tab of the ‘Ethernet Communication Configuration’ dialog box. In this dialog box, all the connected PLC stations can be configured and registered to the Xpanel.

Each field can be configured as follows:

Station Name: STN

Give a name to the PLC. This name will be used in the database window accompanied by the ‘Device Name’.

Station Type: MODBUS

Choose the type of connected PLC among the “Modbus TCP”.

Network ID: 0

Socket Port No: 502

This port number is dedicated to MODBUS/TCP.

16Bit Data Swap

This option swaps bytes of all word- or double-word-sized data. The following diagram shows an example of byte swapping.

Almost all of the data types will be influenced by this option except INT8 / UINT8 / BCD8 / UBCD8.

32Bit Data Swap

This option swaps words of all double-word-sized data. The following diagram shows an example of word swapping.

INT32 / UINT32 / BCD32 / UBCD32 / FLOAT type of Tag values will be influenced by this option.

Using Checksum: This field has no effect. This MODBUS driver always uses a checksum.

Comm. Error Message Pop Up: When this item is checked, Xpanel displays a communication error message box for every Rx and Tx error. Otherwise (unchecked), Xpanel does not display a message for communication errors. This message box will close automatically after a few seconds.

Once the connection type, device name, and device type have been assigned, the [I/O Device Editor] window populates with the default settings for the selected communication protocol. Image Added After selecting the correct [Connection Type] and [Device Type], match the remaining settings to the target I/O device’s communication settings.
