    WAGO recommends that all affected users with WAGO I/O-PRO/CODESYS 2.3 PLCs update to the firmware and use the latest version of WAGO I/O-Pro as soon as it is available. Until the updates are available, we recommend switching off the CODESYS IP port 2455 after commissioning or, if this not possible, use a strong admin password. ### PFC200 Family | Ord.
