August will be IEC month - as we present five different topics all using the Cscape IEC logic editor. In this first installment - we demonstrate how to create and use User-Defined Function Blocks (UDFBs) in Cscape using IEC. While UDFBs are a topic we have covered for Advanced Ladder - there are important differences that need to be pointed out when IEC is used. Join us Tuesdays in August for this series where you may discover that your next project should include a Horner OCS All-in-one Controller running an IEC-based application!
