Introduction Programmable Logic Controllers (PLC) are computers where sequences of

events to be executed are programmed.

Advantages:

Multiple inputs and outputs can be easily wired to the PLCs

Flexibility: the programs could be rewritten to control different systems

Built to work in harsh environments.

Logic Developer Logic Developer PLC: PLC is a next-generation software tool for

programming GE IP Controllers. With Logic Developer - PLC, a controlapplication is developed and then downloaded to a Controller for execution. Fordevelopment of Ladder Diagram (LD), Structured Text (ST), Function BlockDiagram (FBD), Instruction List (IL), and/or Motion programs for PACSystems,Series 90, and/or VersaMax controllers.

Logic Developer state: For development of State Logic applications for Series90-70 and Series 90-30 controllers.

Logic Developer PC: is the PC Control section of Machine Edition, providing alogic component to Windows PC and QuickPanel Control targets. LogicDeveloper - PC is fully integrated with the HMI components created in View. Fordevelopment of Ladder Diagram, Sequential Function Chart, Structured Text,and Function Block Diagram applications for Windows PC workstations.

Motion Developer For development of motion applications for Whedco IMC/IMCjr/SMJ and GE S2K series of

motion devices.

Proficy View Proficy View* is the HMI (human-machine interface) component of Machine Edition*. It can be

used to create and view dynamic graphical representations of your application, and to view datausing logging and alarm capabilities. For development of HMIs (Human-Machine Interfaces) forWindows PC, QuickPanel View/Control, and QuickPanel workstations.

Proficy Change Management The term "Local Change Management" refers to the local systems and project manager

available with all Proficy Machine Edition products. It is the version control, security, and AuditTrail system for your automation and control development process.

Local Change Management features let you: Keep track of changes made to projects and settings, and keep a history of previous versions of

projects (Version Control).

Monitor and record actions performed by users ( Audit Trail).

Control access to projects and settings under Manager's control ( Access Control).

For managing and tracking development of automation projects. This includes Machine Editionand third-party projects.

Example: Lighting Circuit We will try to simulate a lighting circuit, where we have one light and two

switches that are able to independently switch the light on and off. For such asystem we can establish the following rules:

1. If switch A and switch B are both off then the light should be off

2. If switch A is on and switch B is off or if switch A is off and switch B is on thenthe light should be on.

3. If switch A is on and switch B is on then the light should be off.

Lab 1.Problem 1: Lighting system

Design a basic lighting system. The system will have four switches, or inputsand a single output, a light. The switches should control the light based on thefollowing criteria:

1. Any of the three switches if turned on can turn the light on, but all three switches mustbe off before the light will turn off.

2. The fourth switch is a master switch. If this switch is on then the light will be offregardless of the position of the other switches.

Problem 2: Level of water tanks

A ladder logic programme must be designed so that it can monitor the level in 5 watertanks. Each tank provides an input to the programme, which is inactive if the tankcontains water, but active if the tank is empty. The output, a warning light, should beactivated whenever three or more tanks are empty.
