The PLC is a device that processes the signals coming from the sensors, the commands sent to the actuators, and the current status of the devices and equipment. Its fast scan time allows us to have fresh data coming from the sensors every 100 milliseconds or less. It is also reliable, steady, and deterministic. It has the fastest sampling rate and very few instances of downtime, which are planned well in advance. This is very important if we need to gather data without unplanned shutdowns or device reboots that might compromise the quality of the signals or the integrity of the data stream.
