Tim, hi. Would you PLEASE make a video about how to add and program a Incremental Encoder Module 1734-IK in a 1769-L16ER-BB1B PLC? I want to read the Speed of a Belt conveyor in my HMI. I appreciate your Help. Thank you so MUCH.

[@aaw7410]

Why do you use physical trainers and not Logix emulate?
Do you have any videos on teaching yourself with emulate?
Thanks for all you do

[@andersondachery385]

Hi Anderson, while made for the Micro800, see video below where we talk about taking counts and scaling them.

[@sangn1696]

If my PLC power is OFF, would the counter get reset to 0? Same question for RTO. Thank you.

[@TimWilborne]

No, the tags on the Controllogix and Compactlogix are retentive so they will retain their values during power up.

Dear Sir, How to program Ramp up and ramp down in PLC in order to run drive from setting in m/m. ? (Ramp function gen)

[@TimWilborne]

That would make a good video, I'll put it on the list.

[@alangutierrez1447]

Is it possible to use multiple inputs on the same counter ?

[@TimWilborne]

Yes, You would use branches. If there's a chance of two inputs could be on at the same time and you're going to need to look at the one shot instruction also

Hi ,How to add missing instructions toolbar on studio 5000

[@TimWilborne]

View and then tool bars.

[@Skinwalker91]

If I have a ctu and a ctd with a preset of 25 and want to limit the counting function between 0 and 25 how do I do that? I got the ctu to stop at 25 using the dn function but can not figure out how to stop the ctd from going below 0.

[@TimWilborne]

Don't use the DN bit. Use compare instructions. If the accumulated is greater than or equal to 25, don't count up. If it is less than or equal to 0, don't count down.

[@Skinwalker91]

@@TimWilborne Thank you so much for the advice it was very helpful and worked as needed. You're videos are very helpful I learned a lot from them. Thank you.

[@manuellara7629]

A ctu and a timer would be good, unless there is a video up already.

[@TimWilborne]

Hi Manuel. Here is one on tying counters to timers. See if helps.
