Shift Registers - Part 1

[@PLCMentor]

Thanks for the comment and the suggestion. Since these vids are for beginners, I try to keep the layout as the default layout for anyone using logix. Actually a short vid on window positioning and restoring the default when you mess with it would be useful as well as how to right click to allow more flexibility.

At 2:18 you say something very important which should have been given more subject matter time and clarification... These two functions operate on a 16 bit word.. Another key point is that BSL loads the data from the ""Bit Address" parameter into the LSB of the "File" word and BSR loads the data from the "Bit Address" parameter into the MSB of the "File" word.

Its very helpful for all who are learning PLC thanks for uploading...!! become a trainer i also get much simple way from this video to teach student from Mechanical engineering and other stream student ...

I give your video a high rate, becuase you made a very important point while showing bit shift. "Don't use if you can do it a simpler way". Excellent advice. Also for your next video, you could have the ladder logic window horizontal, and the data file window horizontal, with project tree window not shown. then using right click goto to data file, open needed data file window to view. this way you would not have to figure out window positioning on the fly. Hope this helps.

what is the function of a shift register in a p.l.c ?

[@dobiem1]

think about the knight rider lighting scheme:) In all seriousness, you can use BSR for binary multiplication and BRL for division or as the instructor states, for "tracking" an object

Shift /rotate application use which system

[@gerardolasvegasable]

Something is wrong the files are not registering the toggle signals.

please I want to learn me how to give limits for any sensor? ????

I'm not sure what you mean, but you are welcome to come to our weekly web class where we discuss things like this that are important to our students. www.plcmentor.com/PLC-Training/Web-Classroom-Online-Training.aspx

[@enriqueesp]

can you put SQO and SQI commands? PLease

[@adambodom]

sir,any real life example using shift register?

[@PLCMentor]

+Adam Mukhriz No videos on that, but check out my reply to Kumar about uses for them in PLCs.

[@Unknown_Survivability]

you can track an item in a line

[@Mukesh1993-]

SIR.. may i know what has its application ?

[@PLCMentor]

+Mukesh Kumar Well for a basic operation, it can be used for multiplication/division as when you shift one way you are actually multiplying the word shifted by two or dividing it by two depending on the way you shift it. Generally I have seen shift registers in PLCs used to track items in PLC memory. Items on a conveyor may go by a sensor and the shift register can be loaded with 1's for an item present at the sensor at a specific time. As the item goes down the belt, shifting the register will track where that item should be downstream.

tanx sir

You sir made this video make sense.
