1. Sequential Function Chart (SFC) This is a graphical language on top of other programming languages for programming sequential control programs, which are described in detail in Chapter 4. Sequential function diagrams provide a graphical method of organizing programs that can be nested in other languages in sequential function diagrams. Steps, transitions, and actions … Continue reading PLC five programming languages
The PLC control and DCS control system is not a logical level concept. It can be seen from the name: PLC is named after function, and DCS is named after architecture. In principle, PLC can form DCS. Of course, the difference in performance between the two still exists, depending on the product and needs. From … Continue reading What is the difference between PLC and DCS control?

Omron PLC data typeBOOLAddress of a binary bit - a logical Boolean on or off state. This type is typically used for contacts or coils.CHANNELThis is a special data type, for backward compatibility. It is an address (non-bit) to data of any type (unsigned or signed, one or more words), so can be used in place of any … Continue reading Omron PLC data type
