PLC Programming for Line OperatorsĪ line operator would typically have little knowledge about the systems behind the process. Keep in mind that job titles as well as salaries may differ in other regions, companies and industries. Here's an overview of each function from a North American perspective. It's essential to understand the manufacturing job landscape to see how the PLC programming skillset may impact your job, salary, and career progression. PLC Programming average salaries in the USA ( Source: ) The opportunity to learn PLC programming has pushed many toward higher-paying jobs, secure work environments, and excellent career growth. PLC Programming CareersĪs manufacturing facilities around the globe rely heavily on PLCs, and the technology continues to evolve, there is an increasing need of experts capable of developing, supporting, and managing these systems. In other words, PLCs aren't what they used to be a few decades. Examples include Ethernet connectivity for data collection, sensor monitoring through technologies such as IOLink, MQTT protocols allowing server-based connections to be made, and much more. However, they're starting to incorporate some of the features we'd typically see in an Information Technology (IT) environment. They're still robust, process-driven machines. Since their inception, PLCs have come a long way. For the context of discussion, it's not uncommon to reference to PLCs as the entire plant floor control system as they're always tied to sensors, motors, switches, valves, etc. A PLC is typically housed in what's called an electrical enclosure in order to protect it from the harsh environments they may control. In case you're wondering, a PLC looks like a box filled with electrical circuits similar to your desktop computer. Their goal was to replace the relay-based circuits, simplify the process of changing operations, and improve the reliability of the system.Ī Programmable Logic Controller is typically the hardware that will control the process. Based on these principles and the demand of the manufacturing segment, Programmable Logic Controllers (PLCs) were created in the last century. However, they have many common goals: high reliability, high repeatability, and ease of deployment and maintenance. Thus, there is a constant strive to automate every step of the manufacturing process.ĭifferent systems are used in each segment of the automation. Machines are capable of producing more, have a higher tolerance level, and have a higher quality level of craftsmanship when it comes to repeated production. The process of eliminating the human element from this process is not a new concept. Most consumer goods, from food to cell phones, are manufactured at a production facility, shipped through a distribution channel, and delivered to a retailer or directly to your door using automation.
