Using Open Bus Interface.) These Systems are upgraded to add more Intelligence and Capabilities with dedicated PID and Ethernet Modules.Disadvantages of PLC : PLC were Designed for Relay Logic Ladder and have Difficulty with some Smart Devices. To maximize PLC performance and Flexibility, a number of Optional Modules must be added
  5. 5. Programmable Logic ControllersPLC Types Nano (Small) Micro (Medium) LargeBasic criteria for PLC Types Memory Capacity I/O Range Packaging and Cost per Point
  6. 6. Programmable Logic ControllersComponents Central Processing Unit (CPU) Input Output Modules Power Supply Bus system
  7. 7. Programmable Logic ControllersCentral Processing Unit It is a micro-controller based circuitary. The CPU consists of following blocks : Arithmatic Logic Unit (ALU), Program memory Process image memory (Internal memory of CPU) Internal timers and counters Flags CPU performs the task necessary to fulfill the PLC funtions. These tasks include Scanning, I/O bus traffic control, Program execution, Peripheral and External device communication, special functions or data handling execution and self diagnistics.
  8. 8. Programmable Logic ControllersInput module These modules act as interface between real-time status of process variable and the CPU. Analog input module : Typical input to these modules is 4-20 mA, 0-10 V Ex : Pressure, Flow, Level Tx, RTD (Ohm), Thermocouple (mV) Digital input module : Typical input to these modules is 24 V DC, 115 V AC, 230 V AC Ex. : Switches, Pushbuttons, Relays, pump valve on off status
  9. 9. Programmable Logic ControllersOutput module These modules act as link between the CPU and the output devices in the field. Analog output module : Typical output from these modules is 4-20 mA, 0-10 V Ex : Control Valve, Speed, Vibration Digital output module : Typical output from these modules is 24 V DC, 115 V AC, 230 V AC Ex. : Solenoid Valves, lamps, Actuators, dampers, Pump valve on off control
  10. 10. Programmable Logic ControllersPower Supply The power supply gives the voltage required for electronics module (I/O Logic signals, CPU, memory unit and peripheral devices) of the PLC from the line supply. The power supply provides isolation necessary to protect the solid state devices from most high voltage line spikes. As I/O is expanded, some PLC may require additional power supplies in order to maintain proper power levels.
  11. 11. Programmable Logic ControllersBus System It is path for the transmission of the signal . Bus system is responsible for the signal exchange between processor and I/O modules The bus system comprise of several single line ie wires / tracks
  12. 12. PLC Cycle Sense the Input Process the Logic Give Output Programmable controller Inputs Outputs Machine or Process
