PLCs in action In smart irrigation , for example , PLCs can continuously collect data from various sensors , including weather forecasts , soil moisture
levels , and temperature sensors . This wealth of real-time information is then analyzed and processed . When the data indicates , for example , high temperatures and low humidity , the PLC instructs the drive and motor to release just the right amount of water from the pump to prevent crop stress , ultimately conserving precious water resources .
Another great example of PLCs in action can be observed within a bakery setting . PLCs can be programmed with multiple recipes , controlling ingredient dispensing , mixing , proving , baking , and quality checks , all according to the specific product required . The baker can quickly switch between different bakery goods on the same conveyer line , so individual orders can be instantaneously and accurately fulfilled with minimal human input . This means the bakery can consistently produce high quality products , reduce waste , lower unnecessary consumption of energy and , ultimately , save money .
PLCs monitor the end-to-end process , receiving data from sensors that detect any anomalies or bottlenecks . If an issue arises , the PLC can promptly instruct the drives to adjust the conveyor ’ s speed or halt production to resolve the problem . If there are potential issues with the condition of the assets , the PLCs can proactively alert the operator to perform preventative maintenance . This level of real-time coordination not only optimizes efficiency , but extends equipment lifespan and reduces the chances of process failure , which could lead to costly , unplanned downtime .
PLCs also play a pivotal role in industrial safety , offering crucial features such as emergency stop controls and safety interlocks . These measures are critical in preventing accidents and protecting both workers and equipment . For a crane , for example , this might involve restricted safety areas for movement , and collision prevention .
Embrace the automation revolution PLCs hold the potential to further enhance the already transformative benefits of drives paired with motors . Together , they can elevate system and energy efficiency , improve safety , and streamline operations , moving us further down the path towards a sustainable industrial future .
