Programmable logic controllers, or PLCs, are an automation game-changer for a multitude of industries. From automating production processes to improving productivity to reducing labor costs, there’s no end to the benefits of implementing these devices. However, there are numerous PLC brands and models available on the market today, making it a seemingly daunting task to choose one that’s right for your business. Discover what to look for when comparing different PLC brands and models and how to pinpoint which one fits your specific set of needs.
Performance and Capabilities
The first criterion for choosing a PLC should be its performance and capabilities. Consider factors such as processing speed, memory, and input/output (I/O) functions. Determine what kind of control and communication you need to ensure the equipment, machinery, or processes function as required. You can choose a low-end PLC if you don’t have complex requirements, but if you intend to expand, you will need something high-end to accommodate these changes.
Product Flexibility
You should also note the ability of the PLC to work with different protocols, interfaces, and other devices. For instance, if you plan to expand your system, you may need a PLC that features multiple communication protocols like Modbus, Profibus, and Ethernet. Keep in mind, too, that some brands have a proprietary system, which may make it difficult to add new devices when required. Be sure to inquire about these potential limitations when reviewing models from each brand.
Reliability and Maintenance
Your business operations are critical, and a breakdown or malfunction in the equipment could cost you time and money, and even hurt your reputation. Therefore, when comparing PLCs, always assess their reliability and maintenance requirements. It’s crucial that you select reputable brands backed up with warranties and support. Read reviews for honest feedback about the overall performance of certain PLCs and ask your suppliers about recommended maintenance for the products you’re interested in.
Overall Price
Another thing to look for when comparing PLC brands and models is the price tag. Price is a crucial determinant in choosing a PLC since you’ll need to balance cost and benefit. The cost will depend on its performance, features, and ability to meet your requirements adequately. In the long run, investing in a higher-end PLC could be more cost-effective than purchasing a cheaper PLC that can’t meet your needs. Still, it’s best to create a budget for this purchase and avoid paying more than what you can reasonably afford.
Ease of Programming
Lastly, consider the PLC’s ease of programming. The corresponding programming software should be user-friendly and straightforward since you or a programmer will be responsible for creating, modifying, and updating it. Brands with a good user interface and programming software should be a top priority.
