Programmable logic controllers, or PLCS, are ubiquitous in a variety of processes and manufacturing industries today. PLCS were originally designed to replace electromechanical relay systems in order to provide a simpler solution for modifying the operation of control systems. Instead of reconnecting a large number of relays, you can quickly download them from a PC or programming device and change the control logic in seconds.
A PLC is an industrial-grade digital computer designed to perform control functions and is particularly suitable for industrial applications.
Most PLCS today are modular, allowing users to add a variety of functions, including discrete and analog inputs and outputs, PID control, position control, motor control, serial communication, and high-speed networking. PLCS are easier to troubleshoot and maintain, more reliable, more cost-effective, and more versatile than older technologies such as relay groups.
Modicon, short for “modular digital controller,” is both the name of the first PLC product invented in 1968 and the brand that invented it, although it is now owned by Schneider Electric.
While it may not look like a typical home computer, the core of a PLC is exactly the same technology that most people see in the computers and smart devices they use in their daily lives.
Basic component
A PLC consists of several basic parts. They may look slightly different from individual manufacturers, but the purpose and scope of each component is the same. These include the power supply, the central processing unit (CPU), the input/output card, and the backplane or rack that houses the input/output (I/O) card.
As shown in Figure 2, the backplane establishes electrical connections between all the individual components, thus providing a modular design for the PLC. This electrical connection includes a power supply and a communication signal. Many PLC manufacturers use proprietary communication protocols on the backplane so that I/O can securely communicate with the CPU.
Power source
Depending on the application and installation environment, the power supply can accept either 120VAC or 24VDC. As mentioned above, this voltage supplies power to the CPU and I/O modules through the backplane, which come in the form of “cards.” These cards can be quickly added or removed from their slots in the carrier.
It should be noted that the CPU’s power supply does not power field devices such as sensors and coils. This power connection must be established separately from the card.
Central Processing Unit (CPU)
The CPU is the actual “brain” of the PLC, making it a computer. Even small non-modular PLCS contain a CPU. The input signal comes from the I/O card, and the logic program makes decisions based on the signal. If needed, the CPU then commands the output to turn on and off as signals and conditions change.
Programs may include advanced functions such as mathematical operations, timing, counting, and sharing information over modern network protocols. Many of these operations are extremely difficult, if not impossible, for older relay systems.
Input/output card
Sensors, buttons, switches, relays, solenos, and even network devices share information with the I/O signals connected to the screw terminals on the I/O card. These cards can be selected according to the needs of each machine and device. In some small PLCS, the I/O terminals are not modular cards, but are conveniently mounted on the side of the PLC.
