In today’s industrial context, calculating OEE (Overall Equipment Effectiveness) is crucial to maximizing production efficiency. Yet many plants struggle to obtain accurate, real-time data, which complicates strategic decision-making. Equipping your production line with a PLC (Programmable Logic Controller) system for calculating OEE can revolutionize your approach, but many plant managers don’t know where to start. Understanding how these systems can significantly improve productivity and reduce downtime is essential in an increasingly digital industry.

The causes of poor OEE measurement can be varied: obsolete data, human error during manual data entry, or failure to collect accurate downtime information. These shortcomings lead to poor visibility of operations and complicate production management. The consequences are direct: lower product quality, higher costs and an inability to respond quickly to problems. Ineffective monitoring can also mask bottlenecks, seriously undermining overall efficiency.

To optimize OEE, it is imperative to rely on modern, robust solutions. The digitization of the shop floor, through technologies such as PLCs, enables the rapid collection of accurate data and the generation of real-time analyses. Tools like TeepTrak facilitate equipment performance monitoring, downtime analysis and multi-line visibility. By adopting continuous improvement methods such as lean manufacturing and using key performance indicators, plants can not only improve their output but also standardize their processes.

Let’s illustrate this with a concrete example. An automotive parts manufacturing plant faced with frequent and unidentified downtime implemented a PLC system in conjunction with the TeepTrak solution. This enabled them to visualize the causes of downtime in real time and intervene proactively. The transformation didn’t happen overnight, but identifying problems upstream enabled continuous improvement in OEE, resulting in lower costs and better product quality.

Taking action today can transform the future of your production. Start by evaluating your current processes and identifying where bottlenecks and inefficiencies occur. Investing in tracking solutions like TeepTrak and modernizing your systems by integrating PLCs are key steps to adding value to your production. Improving OEE is not just about immediate financial benefits; it also strengthens your company’s long-term competitiveness.
