THE use of function blocks for programming of programmable logic controllers (PLCs) is gaining wider acceptance. Rather than the classic “contact and coil” representation of ladder diagram or relay ...

Many PLC manufacturers have now converted timing, counting, and arithmetic instructions to the more user-friendly function block format, and the programming documentation available for a specific PLC ...

Promulgated in 2005, IEC 61499 defines a reference architecture for open, distributed control systems. Thus, a function block can be used on different processing systems and equipment, as well as ...
