PLC Full Form Name
Full Form of PLC:
Programmable Logic Controller
PLC Full Form is Programmable
Logic Controller. PLC is a computer that is used for the
computerization of processes in industries, e.g. Control of machinery,
production, etc. Almost any machine function can be dealt with using this form
of control system. The system is based on electromagnetic models and is
typically 120 volts AC.
PLCs are very durable and can
withstand rough working conditions including, heat, cold, dust, and moisture.
Also, the language used for its programming is lucid, so it can be programmed
easily. However, PLCs have their share of disadvantages too. They can be used
easily for simple data but are unable to manage the same way with complicated
data. Also, the display of data requires an external monitor.
Languages used in PLC Programming:
§ Ladder Logic: It is one of the most commonly
used languages for PLCs. The rules set in the ladder logic language are
referred to as “rungs.”
§ Function Block Diagram: This
language explains the various steps that exist between the input and output.
FBD is useful to display algorithms and logic.
§ Structured Text: This is a high-level
programming language. It uses sentence commands to ensure that the programming
is done in the right manner, even for complex processes.
§ Instruction List: This is a low-level language,
where the functions are construed of functions and variables. The program is
controlled by instructions.
§ Sequential Function Chart: This
language of programming involves the use of complex control. In this, there are
various processes that occur simultaneously as sub-routines.
