What Is a PLC? A solid-state (electronic) device that controls output devices that are based on control program and input signals Inputs Outputs Control Program
4
Two Types of I/O (Inputs and Outputs)
Digital Also called Discrete Has two possible states Represented by “1” or “0” Electrically: “0” is usually 0 Volts (AC or DC) “1” is a fixed voltage value such as 5VDC, 24VDC, 120VAC,. Technology: Relays, Triac, Transistor, MOSFET, TTL Analog Has many possible states between two values. Example: Temperature sensor. Range of values between two limits. For example: 0°F represented by “0” 100°F represented by “4095” (example) Electrically: 4-20mA, 0-5VDC, -10VDC to 10VDC 4095 1

This is a simple rung of logic, from a PLC program:
Ladder Logic Example This is a simple rung of logic, from a PLC program: Start_Button Light The rung is read as: If the Start Button is on, turn ON the Light. If the Start Button is off, turn OFF the Light. 17

Simple PLC Instructions (IEC 1131)
Contacts Direct Reverse Coils Set Reset Instruction Blocks Arithmetic (+ - * / COS SIN TAN) Binary (Mask, Shift) Boolean (AND,OR,NOT,XOR) Comparator (< > = CMP) Counter (CTD, CTU, CTUD) Data Conversion (ANY_TO_**) Process (PID, SCALER, more…) String (FIND, REPLACE, more…) Time (TON,TOF,TONOFF) S R
7
PLC Control Program Program
Instructions that are used to process inputs and set outputs Primarily written as (Relay) Ladder Diagram: Programs can also be written in other languages Function Block or Structured Text Data (Variables) Examples Start_Button is assigned to a digital input Light is assigned to a digital output Start_Button Light
8
I/O Addressing Often, a descriptive name of the device that is connected to the I/O point is used and, or in place of the I/O variable that describes the physical location on the controller. Example of user-defined name Start Button Light _IO_Embedded_Digital_Input_0 _IO_Embedded_Digital_Output_0 Example of system-defined I/O variable

Applications Today Require a High Level of Control Capability and Advanced Features
Arithmetic (Addition, Subtraction, Multiplication, Division, etc...) Data Comparison (Equal, Greater Than or Equal, Less Than or Equal) Word Manipulation (Copy, Move, etc...) Communications or Messaging data between PLCs Sequencing Data Manipulation Motion and Process Control (Used for Temperature, Pressure, Speed, Flow regulation) Stop light is a perfect example of Discrete I/O Control. It requires Inputs such as street sensors, outputs (the lights themselves), Timers, even counters… Example of PID control is a dryer section of a Paper machine or more simple: the temperature control of boiler.

Connected Components Workbench™ Single Software for All Your Component Devices
Notes about free SW from competitors: Major competitors do not provide free software for download and they require a license serial number. Competitors may provide free licenses to customers but you still have to get the SW on DVD and maintain those licenses. If your PC fails, you must find that license serial number to install it on the replacement PC. With CCW SW you can always download the latest version from RA download site and install it. Competitors may allow you to install a single copy of the software on several PCs with a single serial number but with CCW’s license agreement, you can install it legally as many times as you want.
