Programmable logic controller (PLC)
A programmable logic controller (PLC) is a digital device adapted for control of processes which
require high reliability, ease of programming and real-time responses. Such functionality has long
since replaced hard-wired relays, timers and sequencers which would be required to complete
Programmable logic controllers usually had to conform to IEC 61131-3 standard which defines four
programming languages: function block diagram (FBD), ladder diagram (LD), structured text (ST)
and sequential function chart (SFC). This standard does not support distributed control systems
therefore IEC 61499 standard was published in 2005. The standard is considered an extension of
IEC 61131-3 standard.
WCC Lite supports PLC functionality while conforming to specifications of IEC 61499 standard.
