Most 750-8212 plc's are sold with codesys license installed. This is included in the price. However some Wago customers prefer to run their own software, no codesys, hence they don't require the codesys license. To these customers Wago also sells plc's without the codesys runtime license. Cheaper for these customers, but if you happen to have bought one of these then you are basically out of luck: it won't run with e!****pit.
Not sure how you can determine whether or not your PFC200 controller has the license to be used with e!****pit. Wago support may be able to tell you? They may also be able to tell you if it can be added later or if you are just out of luck. In the latter case, you can still buy a €100 license for your PFC200 controller from 3s-software (makers of codesys) and program your plc with vanilla Codesys v3.
