Usage

The LX6V-8HC module requires the Wecon LX6V-EM□-ECAT remote I/O coupler module for use.

$file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml16196\wps12.png$

After connecting the coupler to Wecon 6 and AC series PLC, the methods of using the LX6V-8HC are as follow.

1. Use on LX6V and LX6S with EtherCAT coupler
  1. 1. 1. First add EtherCAT device
Manual add

According to steps ① to ④ in the figure below, right-click EtherCAT, and click [New] -> [Import], import the ESI device description file of the device^Note.

$file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml16196\wps13.jpg$

✎Note: Log in the Wecon support center (https://docs.we-con.com.cn/bin/view/Expansions/4%20Download/01%20Expansion%20Module/) to obtain the WECON_LX6V_EM_ECAT_1.3.xml 文件.

After the import is completed, select the coupler according to the module model and position of the current module connected (take LX6V-EMB-ECAT as an example).

Scan to add

EtherCAT's device scanning supports direct scanning after connecting or unloading the device.

Select the EtherCAT label, right-click the mouse button and select the scanning device in the pop-up menu.

$file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml16196\wps15.png$

Click the "Scan the device" button in the pop-up window. If the PLC is not connected, an error will be prompted, as shown below;

$file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml16196\wps16.png$

After waiting for the scan to complete, the scanned slave devices can be seen in the left side view.

$file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml16196\wps17.png$

Click [Copy all] to update the scanned devices to the currently configured configuration list, and then click [Save] to update the scanned devices to the configuration list of the project. After saving, click [Close] to update to the configuration list.
