I/O Device Name: Give a device name.
I/O Device Type: Select ‘Ethernet Device’. The device name will be used in the ‘Station Name’ and tag configuration of the database.
Select [Ok] for the ‘Ethernet Communication Configuration’ dialog box to appear.
Select ‘Allen Bradley MicroLogix EthernetIP’ from the ‘Device Type’ the dropdown menu, and choose ‘TCP’ as the Protocol.
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 followed:
Station Name | Give a name to the PLC. This name will be used in the database window accompanied by the ‘Device Name’. |
|---|---|
Station Type | Choose the ‘MicroLogix’ (no other type). |
Network ID | This field has no effect. |
Socket Port No. | The default is set as 4481 for MicroLogix. |
16Bit Data Swap | Data is obtained by swapping bytes of the word- or double-word-sized data. |
32Bit Data Swap | Data is obtained by swapping words in double-word-sized data. |
String Data Swap | Data is obtained by switching bytes of string word data. |
Comm. Error Message Pop Up | With this feature ON, the communication error message appears when Xpanel detects a “Send/Receive” error. |
Fast Mode | This field has no effect. |
Fixed XPANEL Socket Port | Enables the XPANEL Socket Port No. |
XPANEL Socket Port No. | Choose a Socket Port No. for the Xpanel. |
I/O Device Write Enable | Enables writing to the I/O device. |
Data Request Size Limit | Enables the 'WORD' and ‘BIT’ boxes below. Input the maximum word and bit data desired. |
