I. (20 pts) Design a temperature control system using an A-B PLC. The system must maintain the temperature within low and high limits and raise low and high temperature alarms. The A/C compressor (0:2/0) must turn ON when reaches the hi temp. limit in N7:0 and stay ON until the temperature (N7:2) drop to the Low temp. set point in N7:1. Turn ON the HI temp alarm (0:2/1) when the temperature is over N7:0 and Turn ON the LOW temp Alarm (0:2/2) is below Low temp. set point (N7:1). - N7:2=Actual value of the room temperature, known as process variable - 0:2/0 = A/C Compressor - - Location of temperature set points: HI temp N7:0 LOW temp = N7:1 Alarms: Hi temp = 0:2/1 Low Temp = 0:2/2 Include in your design only the wiring diagram and PLC program. Hi Lima N70 Low Limit N7:1 Temp Value N72 Turn A/C 02/0 Activa
