2. Check and Configure IP Addresses

• Default TDE IP: Often 192.168.0.2
• LOGO! Base default: Usually 192.168.0.3
• Set your PC to the same subnet (e.g., 192.168.0.x with subnet mask 255.255.255.0).
• Use the TDE menu: Network Configuration → Set IP Address.

Pro Tip from Vicpas: Always assign static IPs and document them in your control cabinet.

3. Test Connectivity

• Ping the TDE from your PC command prompt.
• Run network diagnostics in Windows.
• In LOGO! Soft Comfort, use the connection test tool (green bar indicates success).

4. Resolve Software Detection Issues

• Run LOGO! Soft Comfort as Administrator.
• Avoid IP conflicts with other Siemens tools.
• Set PC network adapter to match the correct subnet.

5. Fix IP Loss After Power Outages

• Remove SD card and configure TDE independently.
• Verify program file on SD card does not overwrite network settings.
• Consider installing a SITOP UPS for critical applications.

6. Enable Web Server and Remote Access (Securely)

• Avoid direct port forwarding for security reasons.
• Use VPN solutions (e.g., Tailscale, WireGuard) for remote monitoring.
