The tutorial package of PLC, PLCTUT, built up is a full tool of multimedia to be utilized as a teaching and learning aid of programmable logic control. This package is planned as a teaching aid and laboratory for a first course in PLC in which interactive notes of hyperlinked, audio, video and animations, are integrated to support the laboratories, lectures and coursework carried out. For instance, with PLCTUT, animations, audio, video and text are accessible which can be utilized to demonstrate how the simulation, theory, and a real laboratory experiment undertaken agree, as projected.
Information sources on PLCs; and Practical programming of PLC. PLCTUT has been generated by the Macromedia Director 6.10 Director multimedia authoring tool is utilized to incorporate media from applications of Macromedia studio such as xRes, Sound ForgeXP, and Extreme 3D to make whole multimedia applications.
The software of multimedia has been developed on computers Pentium/200 MHz PC prepared with 4.2 GB hard disc, 64 MB memory, and displays of color graphics. Delivery platforms have to be able of running Windows NT or 95 and the minimum requirement will be a processor of 486DX4/100 MHz with memory 16 MB and color graphics SVGA. Also necessary are 16-bit audio cards.
Application examples of PLCSIM and PLCTUT
A number of models are currently known to illustrate characteristic student applications of the packages of PLCTUT and PLCSIM. The examples of ladder diagram programming given form a small part of the practical programming set exercises given in PLCTUT.
PLCSIM Contacts and coils example
The PLC simulation has 12 input contacts and 8 output coils. It is also probable to program latched coils and internal coils. Coils and contacts can be engaged to execute combinational logic problems relating logic functions for example OR and AND which can be utilized for complex and simple, control problems.
An example of PLCSIM a latch circuit is on the simulator, switches linked to inputs X0 and X1, are utilized to characterize the push buttons of normally open. The output is observed by the LED simulation linked to output Y0. Pressing the switch linked to X0 on/off creates operation of the initiate push button and turns and holds output Y0 on. The latch is set. The push button of stop is illustrated by the switch linked to X1. Running this switch on/off switches the output off. This case, the latch is reset. Operating of a circuit latching can be obviously illustrated by the simulator.
