Benefits of a Programmable Logic Controller

A Programmable Logic Controller or a PLC is a type of microprocessor that can control industrial processes without the use of a computer. It internalizes instructions, timing, logic and counting to effectively control the processes. They are used in industries to modify operation processes by monitoring crucial information.

PLCs have become a popular choice for controlling manufacturing operations. It is built based on the common principles that are used in computer architecture so it can perform complex tasks quickly and efficiently. Traditionally, relays or contactors were used to carry out electrical control and as they are designed for a specific function, whenever there is a change of requirement, they needed to be modified all over again. This is something that you will not need to deal with in PLC as it is a versatile system. Modern automated control systems Perth are quite compact when compared to their traditional counterparts and you get increased reliability as well. After a programme is written and tested, it can be used in other PLCs simply by downloading the programme. PLC will contain all logic required to scan and produce outputs in its memory. Therefore, there is no room for error. As solid state components can be used, the reliability of the system will increase as well.

The ability of PLCs to communicate with other computer equipment, controllers and devices allow them to mesh seamlessly in an industrial system. It allows the PLC to gather data, supervise other devices, monitor other devices as well as download programmes and upload them. There are different communication protocols that can be used. Because PLCs focus on real time applications, they operate extremely fast. PLCs can respond very fast and this is why it stands heads and shoulders above alternative technologies. Because of the resident diagnostics that are available in PLCs it allows the users to easily troubleshoot problems. A user will be able to detect any issues in software or hardware without delay and apply corrective procedures. These control systems are easy to install and maintain. You can easily connect the input and output modules in a PLC.

Rewiring a circuit in a relay system can be quite difficult and time consuming. But with the development of PLCs, you only need to change a programme or create a new programme. This user programme will assess the relationships and connections between the inputs and the outputs. The manufacturer of the equipment can send out new programmes for system updates and this can be modified by the users as they wish. You can also add extra security by using passwords for software and key locks. Changes to functions of the PLC can be made to expand its use and flexibility. This can be done by adding more function modules. While PLCs were produced as a solution to the challenges of relay control logic, they have done so much more. They have also reduced costs when it comes to operation. Because of this relay control systems have been replaced by PLCs in most applications.
