Discrete Sensors 101: Sensor types and best practices
网页2018年6月7日 · A discrete sensor sends an on/off (yes/no) signal, often allowing the PLC to ignore analog threshold, deadband, detection speed, and other complexities. That signal could mean “I see a part,” “machine air pressure is above 80 psi,” “actuator has reached position,” “heater at temperature,” or a number of other situations.
