I am having major issues with writing a PLC program. I am taking an advanced PLC course at the local community college and this course is much different than when I had an introduction PLC class, in 1998. This class was not supposed to be part of the degree, but they eliminated an existing class in favor of this one.
I initially learned programming on the old Allen-Bradley 2/15 PLC's. Although the concepts and ideas are essentially the same, this is a totally different way of doing things in 2011.
I have attached 4 jpeg files with what the program is supposed to do. I am lost when it comes to starting the program as well as which instructions, etc. to put in the program.
This program involves start and stop buttons in order to energize a motor, toggle switches and math formulas. These instruction sheets are very descriptive so I don't know if there's anything else I should say in this posting. If you have any questions, please contact me.
I don't have any type of program file I can even send. My apologies if there is a lack of information.
The basics of the program is to push a green start button and turn on a motor for a certain time period. The red stop button will obviously shut off the motor. Lights and a motor have to be on and off for certain periods of time and must come on and off at different intervals.
Honestly, I am completely lost with this. Any help is much appreciated. Thank you very much.
