An IEC 61131-3 system can still be programmed as a single Ladder program if required. Programming systems may provide a option to create a simple IEC 61131-3 configuration containing one resource, one task, and one program instance of a program type. All of this could be created automatically so the user is only concerned with developing a single ladder program. Function blocks and other IEC 61131-3 constructs do not need to be used. • Will IEC 61131-3 languages result in applications that run more slowly and require more memory than using simple ladder? Attempting to implement IEC 61131-3 constructs such as function blocks on PLCs that were originally only designed to support ladder programs, will inevitably have performance and memory overheads. PLCs specifically designed with firmware to support the execution of IEC 61131-3 programs should not be noticeably slower than classical ladder based PLCs. The improvements in software structure from IEC 61131-3 should allow users to be able
