![]() ![]() The poor networking connectivity causes legacy PLCs to have limited data exchange with high-end systems. These networks end up creating problematic data silos. PLC automation networks are usually closed-loops, where valuable and critical data ends up staying locked inside factory floors. Considering a PLC with access to the Internet a few years ago would have seemed like an absurd idea.īelow are three of the most common challenges that PLCs present: a. Although most modern PLCs can communicate with one another or send information to a local dashboard using basic networking capabilities, they were not designed for remote communications. All this input makes PLCs concentrate a massive amount of operational data, which unfortunately ends up locked in within factories. PLCs continuously monitor the state of input devices such as sensors, make decisions based on a custom program, and trigger an output to a control device, such as an actuator or alarm system.
