Specialty digital computers called programmable logic controllers, or PLCs, are frequently employed in industrial automation applications to regulate machinery and procedures. They do this by continuously gathering and analyzing data from field input devices—such as limit switches, pushbuttons, and sensors. After examining the incoming data and using their preprogrammed internal logic, they turn on the relevant field output devices—such as relays, motor starters, and indicator lights—to finish the designated control task in the machinery or industrial process.
PLCs are the backbone of industrial automation because they can be configured to monitor and manage a vast array of industrial gear and equipment, such as assembly lines, robotic devices, conveyor systems, production lines, elevators, and machinery used in food processing. To ensure automated and seamless operation, always purchase Allen Bradley PLC parts.
Things to Take Into Account While Choosing a PLC
Allen Bradley PLCs come in a variety of sizes and types to suit nearly every industrial automation need. Therefore, there are a number of things to think about in order to determine which PLC type or brand would be ideal for a certain application. Among them are:
CPU Speed: The size and reaction rate needed for the system to be controlled will dictate the CPU speed of the PLC you want to employ.
Memory Capacity: How much PLC memory will be sufficient? Will the PLC system need to have an external memory module added for the application?
PLC Redundancy: What degree of redundancy would the application need? Does a PLC system need to be redundant? Will there be synchronous or independent redundancy?
I/O Count: A PLC’s I/O capability is the greatest number of distinct input and output devices it can detect and manage, respectively. Because of this, when choosing one, make sure to consider how many input and output devices the PLC will need to monitor or operate at any given moment. Will the PLC need to be connected to external or remote I/O connections as well? If so, choose the relevant add-ons to make the connection.
PLCs are often classified into the following main groups according to the highest number of inputs and outputs they are able to manage:
Nano PLCs: A maximum of 32 I/O operations can be handled by them.
Micro PLCs: 128 I/O points are available.
Up to 256 I/O functions are provided in small PLCs.
Medium big PLCs: These PLCs use quick I/O scan speeds to control a large number of discrete elements, over 256 I/O points.
Communication Protocols: Which communication protocols will be utilized, and with which field devices, programmable terminals, other PLCs, HMIs, SCADA systems, or industrial control systems will the chosen PLC need to communicate? PROFINET, ControlNet, EtherNet/IP, Modbus Plus, DF-1, Profibus, EtherCAT, DeviceNet, SERCOS interface, and CANopen are a few examples of PLC communication protocols.
Compatibility of Hardware and Software: Will a custom PLC control system be created? Is it going to require interaction with the current control hardware and software? Does the system have to interface with already-existing hardware and software, or is it being developed from the ground up?
Special Functions: In addition to basic control, would the chosen PLC need to be able to perform special functions like robotics, motion control, or safety-related tasks?
Reliability: Will the PLC system’s operation experience minimal to no downtime, as in mission-critical applications? How long is it planned to last?
Scalability: Is it possible to scale the chosen PLC system up or down to meet the application’s future requirements?
Environmental Considerations: In what kinds of environments will the PLC operate? Will it need extra features like conformal coating, a wider operating temperature range, or a more durable model for harsh environments?
Cost: How much can be spent on deploying the PLC system? Has the total cost of the PLC system—which includes the price of the hardware, software licensing, installation, computing, integration with the current automation systems and plant, maintenance, tech support, and any additional expenditures for upgrades—been taken into account?
