Online PLC Programming Tutorial for Shift Registers - Using The BSR And BSL Bit Shift Instructions

Online PLC Programming Tutorial for Shift Registers - Using The BSR And BSL Bit Shift Instructions.
In this PLC tutorial animation, we look at the BSR (bit shift right) and BSL (bit shift left) instructions used with Programmable Logic Controllers to create shift registers. The input fields for the instructions are discussed inclucing the File, Control, Bit Address, and Length fields. Where and how status bits such as the unload bit, the error bit, the enable and done bits are accessed is also discussed. The demonstration then moves on to a practical example of a bottle line application. Tracking of scrap or damaged product along the line is illustrated step by step using an example shift register. The video is part of the web based supplimental tutorial materials provided in the PLC Technician Certification Program offered by us at George Brown College. Earn your PLC technician certificate with this self paced, home study distance education course which offers continuous enrollment, online exams, supplimental web resources, a PLC software simulation tool, as well as telephone and online tutorial and technical support.

Very True ! For minimum. process cycle time (maximum throughput), the gap would be removed, and the register would only need to track the damaged bottle from the point of detection, up until the scrap gate. After that, it would not be required at any point down the line.
Thanks for the insightful comment !

Excelent video. Animation makes the difference. Thanks a lot for sharing!

Wonderfull Information, Sir !!!!!!!

Sure thing, keep up the great videos.

Also in a real world application of the Registers with a physical gap where the scrap bottle used to be may not be maintained, as it reduces process cycle time. In that case when scrap bottle is dumped, the scrap bit would be reset to a zero (0), else the fill logic would not work correctly.

For this kind of applications I prefer to used ffl and ffu. Saludos

A valid choice. I made this video to illustrate the use of shift regs for my students. They had not covered stack operation as of the time I made this video, so it was a good example of the action of a shift register.
