Unitary PLC: Its Usage and Benefits


Has anyone ever heard about unitary PLC? When talking about PLC system, software and implementation, people mostly think that all PLC system is just the same. They’re uniformed and they come within one single design and application only. Well, it’s not completely true because the PLC system and products are different from one another. The software is also different because the each program is designed to deliver different function and usage. Well, with unitary PLC, users can also have different usages and benefits from the other designs.

Unitary PLC: Understanding PLC Concept
When talking about unitary PLC, we can’t separate the term with PLC application. The Programmable Logic Controller is a special system that is designed to make machine works automatically, so that the industry won’t be depending too much on human resource. The basic concept of the PLC system includes input, process, and output. Everything must work well so that all the processes can run smoothly and well. The input should go along well with the process so that the required output can be reached and gained. The system is using special ladder logic program to make it run. Based on the program and the design of the machines, users can have whatever types of work and operation they want. Besides the unitary design, they can also have other types, such as rack mounted or modular types. Despite the design and the types – unitary PLC, modular, or mount-rack – all PLC systems are the same: they can be used and operated on going basis and they can be used in harsh and tough environment.

Unitary PLC: The Main Basic Types
Besides the unitary PLC, there’re two other types of PLC system: the modular and the rack mounted one. The unitary type is considered the most basic and simplest kind of PLC system. It consists of one box only, which accommodates processor, software, and output-input connectors. The modular type is the one consisting of several modules or several programs that can be used to adjust the users’ preference and need. This type of PLC system is suitable for complicated processes and operation, where the overall program is more lenient and flexible; not fixed. The rack mounted type is basically almost the same with the modular one, but the implementation is different. In modular type, different modules will be connected directly to the base unit. In rack mounted type, however, the modules remain separated. People have their own reasons why they choose the unitary PLC or the other types.

Unitary PLC: The Benefits of Using It
There’re reasons why people choose the unitary PLC. First of all, this system is suitable for small to medium scale business. It’s compact and it’s very simple. Second, because of this special trait, it can be attached directly to the system being controlled. The simple and basic design allows portability and easy access. With such flexibility and easiness, the users won’t have to fumble with messy applications or difficult procedures. It’s true that the unitary PLC may be very simple and basic, but it’s a perfect choice for small business with fixed type of operation.
