When you designate a device name and select ‘Ethernet Device’, the 'Ethernet Communication Configuration' window will appear as shown below.
(1) Communication Port
...
Item | Description |
Device Type | Select the type of target device’s protocol. ‘MODBUS TCP’ can be used for any device which support Modbus over Ethernetdevice. This also selects the driver used to communicate with the device. |
IP Address | Enter the device’s local IP address. This field is enabled only when the local Xpanel device type is CM-NP/iNP. |
Protocol | Select the Ethernet protocol to use. You can select UDP/IP or TCP/IP. |
Network ID | Enter the network ID if required by the device protocol. |
Node ID | Enter the node ID if required by the device protocol. |
Time Out | Timeout is a feature to set the standard of communication fail and success. If the 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 No. | Assign the number of communication retries retry attempts after the a communication failure. |
Initialize the Tx Frame When Timeout Occurs | Select this option to initialize the Tx frames that are registered during the timeout period. |
Dynamic IP | Select this option if you use dynamic IPare using a dynamic IP address. This field is enabled only when the Xpanel device type is CM-NP/iNP. |
※ Refer to each driver’s manual for detailed configuration options.
(2) Station
From the ‘Station' tab of the ‘Ethernet Communication Configuration’ window, press the 'Add Station’ button to add a new device for the chosen communication port.
...
Item | Description | |
Edit | Brings up the configuration window for the selected station. | |
Delete | Deletes the selected station. | |
Add Station | Configures communication options for the target device. | |
Station Name | Designate the station’s name. You cannot use special characters. | |
Station Type | Select the station type. Different station types are available depending on the device type you selected in the [Communication Port] tab. | |
Network ID | Enter the network ID if required by the protocol. | |
Node ID | Enter the node ID if required by the protocol. | |
Unit ID | Enter the unit ID if required by the protocol. | |
IP Address | Enter the target device’s IP address. | |
Socket Port No. | Enter the socket port number of the target device. | |
16Bit Data Swap | Swaps the upper and lower bytes of word data (16-bit) during communication. | |
32Bit Data Swap | Swaps the upper and lower words of double-word data (32-bit) during communication. | |
String Data Swap | Supported by some communication drivers. Swaps the upper and lower bytes of each word (16-bit) of string data. | |
Comm. Error Message Pop Up | Select this option to enable a communication error pop-up message. This will appear on the Xpanel device whenever a communication error occurs.  | |
Fast Mode | Select this option to use fast mode, which speeds up the rate of data transfer. This option is only available for certain station types. | |
Fixed XPANEL Socket Port | Select this option to fix the Xpanel socket port number at a specific value. | |
Xpanel Socket Port No. | Assign the Xpanel socket port number. | |
I/O Device Write Enable | Allows the device to make data write requests to Xpanel. | |
Data Request Size Limit | Sets a limit on the number of WORD and BIT data values that can be requested by the device. | |
WORD | Sets the maximum number of words (16-bit) which can be requested by the device. | |
BIT | Sets the maximum number of bits that can be requested by the device. | |
