FB по факту не нормирован по спецификации PCS7 и не отвечает полностью требованиям ProgrammingStyleGuide for PCS7.

Он к ним приближен, но не отвечает полностью. Примерный проэкт предназначен для демонстрации функционала связки SCL+CFC+WinCC, но без использования конкретно PCS7. Этот момент надо учитывать при применении.
