At first it may seem strange to have both a contact and a coil in a PLC program labeled identically (Note 3 ), since contacts are most commonly associated with inputs and coils with outputs, but this makes perfect sense if you realize the true meaning of contacts and coils in a PLC program: as read and write operations on bits in the PLC’s memory.

ACC – Helping you with your automation control tasks Practical tips and techniques for automation control tasks. We will answer questions and provide sample programming solutions. PLC A later effort to enhance the clarity of PLC programming was the concept of addressing variables in a PLC’s memory by arbitrary names rather than fixed codes. The IEC 61131-3 programming standard refers to this as symbolic addressing in contrast to “direct” (channel-based) addressing, allowing programmers arbitrarily name I/O channels in ways that are meaningful to the system as a whole.

Since ladder logic is a graphical programming language, the PLC programs written in ladder logic are a combination of ladder logic symbols. All the symbols can be found in the standard defining ladder diagram programming: IEC 61131-3. But, those standards are quite expensive if you are just looking for the symbols used in ladder diagrams. A Programmable Logic Controller, or PLC for short, is simply a special computer device used for industrial control systems. They are used in many industries such as oil refineries, manufacturing lines, conveyor systems and so on.
