PLCs have changed since they were first developed in the 1960s, and there are a number of upcoming trends and advancements to be aware of. Among the prominent ones are:
1. Industrial IoT:
Real-time monitoring, preventive maintenance, and improved automation capabilities will be made possible by the connection of PLCs with the Industrial Internet of Things (IIoT).
The Industrial Internet of Things (IIoT) trend, which involves connecting numerous industrial equipment and gadgets to the internet so they can interact and complete automated activities more intelligently and effectively, is being adopted by the automation sector. With the use of sensors, cloud computing, and other cutting-edge technology, IIoT enables organisations to simplify operations, reduce downtime, and increase productivity. This tendency is the driving force behind the advancement of increasingly intelligent and interconnected PLC systems that can interface with a range of other technologies, including as machine learning, big data analytics, and artificial intelligence.
2. Edge Computing:
Edge computing enables data processing to take place nearer to the data source, lowering latency and enhancing system responsiveness. As a result, industrial processes may be controlled more effectively and efficiently.
Edge computing is a distributed computing approach that pushes data processing and analysis closer to the source of the data rather than depending on centralised cloud computing resources. Edge computing can assist PLCs in lowering latency and enhancing real-time control by enabling data processing and analysis to be done closer to the PLC and the devices it is managing at the network’s edge. In environments with spotty or unpredictable internet access, this can help to improve the efficiency and reliability of PLC operations. Thanks to the advancement of edge computing technologies, PLCs can now analyse data in real-time and take autonomous choices without the aid of external computer resources.
3.Artificial Intelligence:
The use of AI into Rockwell Automation PLCs can enhance decision-making abilities and allow for the automation of increasingly difficult activities.
Artificial intelligence (AI), a subfield of computer science, focuses on developing computer programmes that can carry out operations that ordinarily call for human intellect, such as voice recognition, visual perception, decision-making, and language translation. PLCs may use AI to become more precise and effective control systems that can adapt to changing conditions and constantly enhance performance. For example, AI algorithms may be applied to predict maintenance needs and schedule downtime, identify abnormalities in machine performance and alert operators to possible issues, or improve production processes by analysing sensor data and modifying control parameters in real-time. AI technology is evolving and becoming more accessible.
4.Cloud Computing:
PLCs may be accessed and monitored remotely thanks to cloud computing, which can also make it easier to integrate various systems and data sources.
Cloud computing refers to the delivery of computer services such as servers, storage, databases, networking, software, and analytics through the internet or “the cloud”. With cloud computing, businesses may access and use computer resources as needed without spending money on expensive infrastructure. Manufacturing and industrial automation are two areas that are increasingly utilising cloud computing. Numerous benefits, such as cost savings, scalability, and flexibility, may be offered. PLCs can use cloud computing for data archiving, analysis, and remote access.
5.Cybersecurity:
Cybersecurity will be more crucial as PLCs become more interconnected and linked with other systems in order to defend against possible threats and assaults.

6.Wireless Connectivity:
Utilising wireless networking technologies like 5G and Wi-Fi 6 can make industrial systems more adaptable and mobile.
Wireless connection in the context of PLCs refers to the use of wireless communication technologies like Wi-Fi, Bluetooth, or cellular networks to facilitate communication between PLCs or between PLCs and other devices. Wireless communication can replace physical cable, which can be time-consuming and expensive to install and prevent remote access to and monitoring of PLC systems. However, using wireless connectivity can also pose security issues, thus the system’s security must be ensured by taking the necessary steps. Additionally, the placement and design of wireless devices must be carefully considered since environmental variables like interference or signal loss can affect wireless communication.
7.Open Standards:
Adoption of open standards like MQTT and OPC-UA can make it easier to share and integrate data among various industrial systems while also enhancing interoperability.
Open standards are technical specifications that define how multiple technologies should connect with one another. They are consensus-based, openly available, and vendor-neutral. Thanks to open standards, Allen Bradley PLCs may communicate with other systems and gadgets in the industrial automation ecosystem as well as with other PLCs of different types and brands. Open standards can minimise vendor lock-in, increase flexibility, and lower costs for end users. Several open standards that are relevant to PLCs include OPC UA, EtherCAT, and MQTT.
Overall, it is projected that PLCs will exhibit increasing connectedness, intelligence, and adaptability in the future, as well as a stronger focus on cybersecurity and open standards.
