    If the PLC runtime is running, but you do not need it, you can deactivate the plc runtime programming port over the product settings in the web-based management. You can find this option under "Configuration > PLC Runtime Services > CODESYS 2 > communication enabled". As general security measures strongly WAGO recommends: 1. Use general security best practices to protect systems from local and network attacks. 2. Do not allow direct access to the device from untrusted networks. 3. Update to the latest firmware according to the table in chapter solutions. 4. Industrial control systems (ICS) should not be directly accessible from the Internet, but should be protected by consistently applying the defense-in-depth strategy. The BSI provides general information on securing ICS in the ICS Compendium (https://www.bsi.bund.de/SharedDocs/Downloads/EN/BSI/ICS/ICS-Security_compendium.pdf).
