Well done thanks for making this. Only question I have is how to get back to step 0 if you wanted to reset all of the outputs... (I guess you could have an extra step at the end which loaded zeroes for each bit) and also I was wondering if the control input needs to be anything in particular, or just something unique for that particular instruction. Thanks!
Great questions. There is no way to get back to step 0. If you want all of the outputs to go to zero your need to program that or program in a clear that activates at the right time. The control input can be any input that make the rung logically true when you need the program to sequence. Hope this helps!
@@BayMacDre415 you would use the control instruction R6:0/DN to activate a ( "move" instrucion) and put a zero so that it moves it to control instruction R6:0/POS that way it start from zero position.
Simply use RES instruction and address it with R6 control parameter, e,g you used R6:0 in the SQL instruction then use RES addressed with R6:0 and toggle it with input bit
Thanks for the video... 😇 i have a question to ask... Can we use sequencer for counting function.. Like i have to perform counting operation but not using counter.. So should I able to use sequencer for that?
Hello Klette Tech I am making a program on RS Logix Micro to control a traffic light. I got kinda stuck when I tried to control the crosswalk. For example, If I want to turn on Northbound Light with Northbound crosswalk I put a simple push Button which would turn on crosswalk same as Northbound light. Now the problem is if Northbound Light is already on and then somebody comes and presses push Button for crosswalk, Crosswalk then would turn on immediately instead it should turn on next time northbound light come on. I tried so many different ways to make it work but I could not. Could you please give me any suggestions in this regard.
That is a big questions. Have you tried to use a FLL instruction to move it into the storage location. Or Latch the sequences in subroutines and have the crosswalk instructions activate which subroutine is needed. Does this help.
@@KletteTech Hello KletteTech Thanks for replying. Eventually, I was able to accomplish the desired result by calling internal bits and manipulate them into the program. Since I am not familiar with the instructions that you have mentioned above. But I will love to learn them and then approach the same problem with that instruction.
I need some information on RS Logix programming for AB Micrologix 1200. If suppose, we have a sensor in field connected to the Digital Input of the controller. This sensor is connected to a conveyor, this gets signal ON and OFF contentiously every second or less than a second. I need to activate an output relay port only if the input is constantly ON for more than 5 seconds. Please advise how this can be done.
Great Questions. Create a TON with the sensor being the input. no memory. If the sensor is on for preset of the timer lets say 5 seconds the done bit goes true. Have the done bit activate the relay. Does make sense?
@@KletteTech Thank you for your reply. "No Memory" this means the timer will get reset to "0" every time the input changes its state from ON to OFF ? Please explain how to set this timer property "no memory" in RSLogix 500 timer.
@@jeromenote9739 Yes. if you have memory on the timer's input anytime the input goes true the timer will finish timing and the done bit will go true. If you want the output to activate when the input is only on for 5 seconds (lets say the conveyor stopped and it was not suppose to) then no memory in parallel with the input. does that make sense? Did i read you question correctly?

Great video. It was able to fill the gaps in my self taught understanding and give me a finished product. Thank you
Excellent. Congratulations from Brazil.
Thanks.
Very nice Explanation. I would not have guessed that I will understand this instruction that easy.
Thanks.
I am happy to hear that! Thanks for the feedback
Very good teach , help a lot to understand the program for troubleshooting
thanks
Thanks a million times Sir !
Most welcome!
Very useful video! what plc tool are you using? Where can we download that software?
👍👍👍

Sorry, I meant the Control parameter within the instruction block (R6:0 used in this example)
Not the toggle bit, or enable bit

how did you get the " light board " i can not seem to find a software for that i already have rslogix micro
That is actually real I/O in my shop. I use picture and picture to to show it on the screen. Thanks for watching.

You might be able to but it would a lot of work to set it up. A counter would be easier
