Temperature Protection System – PLC Logic Question

Temperature Protection System – PLC Logic Question A heater is controlled based on temperature feedback. ✅ Condition: Heater should TURN OFF when temperature exceeds 85 °C Heater should TURN ON again only when temperature falls below 75 °C ❓ Question: 1️⃣ Which compare instructions will you use in PLC to achieve this logic? 2️⃣ How will you avoid frequent ON/OFF (chattering) of the heater near the setpoint? 💡 Hint: Think in terms of hysteresis / dead band logic, not a single compare instruction. 🧠 Drop your logic approach or ladder idea in the comments! #PLC #IndustrialAutomation #ControlLogic #TemperatureControl #Hysteresis #PLCProgramming #RealWorldPLC
