How-To: PLC Visu Setup

This guide describes the configuration of the WDX Runtime (PLC Visu) to enable communication between the WEVA server and WAGO controllers.

Prerequisites​

1. Access the Administrative Console​

Navigate to the WDX web interface in your browser.

  • URL: http://<host-ip>:7081
  • Default Login: Refer to WAGO WDX technical manual.

2. Configure Device Driver​

To poll data from WAGO controllers, a Modbus driver must be active.

  1. Navigate to Settings > Drivers.
  2. Enable the Modbus TCP/UDP Client driver.
  3. Set the Cycle Time (Default: 1000ms). In high-density environments, consider increasing this to 2000ms to reduce CPU load.

3. Communication Hardware Port​

Ensure the host machine's firewall allows traffic on the Modbus port (Default: 502).

# PowerShell command to verify port 502 is open
Test-NetConnection -ComputerName <controller-ip> -Port 502

[!NOTE] If the test fails, verify that the WAGO controller's Modbus service is enabled in its Web-Based Management (WBM).

4. Verification​

Status of the driver should indicate Running in the WDX dashboard.
