![]() To remotely monitor these, you will need a hardware device acting like a gateway, which communicates with your PLCs using legacy interfaces (like serial) and protocols, gathers information, and forward them to a cloud service. Keep in mind that many Programmable Logic Controllers may not be able to communicate using modern interfaces and protocols like Ethernet, USB, or TCP/IP. They can vary in complexity, from simple tools that report raw values received from your PLCs to more sophisticated ones that include features such as historical data analysis, performance baselining, or device management. Programmable Logic Controller monitors are tools that can be used to monitor the status, health, and performance of PLCs in your industrial infrastructure. Frequently Asked Questions About Programmable Logic Controller Monitoring What are Programmable Logic Controller monitors? Over the past 50 years, PLCs established themselves at the heart of industrial operations worldwide, and became important components of larger trends like Machine to Machine (M2M) communication and the Industrial Internet of Things (IIoT), which themselves are part of what we call the “fourth industrial revolution” or “Industry 4.0”. Programmable Logic Controllers (PLCs) are industrial computers used for the monitoring and control of manufacturing processes, including environmental and machine sensors, assembly lines, industrial robots, and much more.ĭeveloped for General Motors in 1968 to replace earlier, analog and hard-wired automation systems, PLCs gained popularity due to better reliability, expandability, and easier and more flexible programming, allowing for quick iterations of manufacturing processes and better tailoring to specific needs. PRTG, Ixon, CNCNetPDM, Zabbix, Modbus Monitor, PLC Analyzer Pro, MachineMetrics, AnyViz, Bridgera Monitoring, DataDog.In this article, we will present some of the best options available and hope to help you choose the best one for your needs. PLCs are such crucial devices that they gave rise to a whole industry dedicated to supporting them, including PLC monitoring tools that can ensure they are working correctly and alert in case of failures.
