I can't connect to the new PFC200 via Ethernet

Here is the manual:
PFC200 Manual

There is possibility to setup temporary IP address

For each bridge used, the assigned interfaces are assigned their own address, whereby
bridge 1 receives the IP address “192.168.1.17”, bridge 2 the IP address “192.168.2.17” and
so on.
No reset is carried out.
To set temporary fixed IP addresses, proceed as follows:

  1. Set the mode selector switch to the STOP position.
  2. Press the reset button for more than 8 seconds.
    ⮕ Execution of the setting is signaled by the “SYS” LED flashing orange.
    If you make changes to the IP configuration of a bridge after enabling the temporary IP ad
    dresses, the new settings are permanently adopted and applied immediately. The configured
    bridge exits the temporary IP address mode. The other bridges keep the temporarily set IP
    address until restart / reset.
    To cancel the setting, proceed as follows:
    • Perform a software reset.
    or
    • Switch the product off and on again

Here is also the WAGO Ethernet Settings program:

it uses port 6626 to setup the controller, so maybe you can access this way.

For codesys, check the firmware version on you controller (wbm first page or Ethernet Settings) and look at this table for compatibile Codesys version:
