That is a great video, as always!! I tried to find out the max PPS that a Micrologix HSC could read and didn't find it in the manual. (maybe I didn't look hard enough) I called our A-B dealer rep and his engineers couldn't answer the question but said my 32 ppr encoder would work at 1800rpm. Thank You again!!

Thanks, the high speed function file is one of the lesser known features of the Micrologix PLC. You can do a lot of high speed applications with it that you would normally think you need a PLC with a lot more horsepower for.

Hello, can you please tell me how i stop minus counting of encoder in AB PLC, as well as if my motor is run and stop after some time i push stop button and application is stop but due to weight it has slippage in application how can i stop pulse counting in that slippage.

@TimWilborne 4 жыл бұрын

You can use the Counting Enabled (CE) to disable the counter when you do not want it to count. To stop reverse counts, you need to change your HSC Mode (MOD). I'm guessing you have it on 6 or 7. For an up only counter it should be 0 or 1. Also note that this will disable input 1 and your counts will be 1/4 of what it was previously.

Very interesting. I have a quick question: I programmed an inspection system inspecting with AB ML1400 (to check the count and see the correct orientation of containers). My counter is working very well but occasionally it will send false alarms when the count is right. Would you have any advice to solve the issue?

When you pressed accept rung edits, I:00 shows Bul.1763 why? Secondly we never had physical input at I 00 then why its flashing (receiving input).

@TimWilborne 4 жыл бұрын

Hi Muhammad. I:0/0 is on the base unit of the Micrologix 1100 (1763-L16BBB) we were using, that is why it said Bul. 1763. Inputs 0 and 1, I:0/0 and I:0/1, were connected to the PLC Tools SIM-EOC Encoder Simulator which was sending pulses to those inputs in a quadrature encoder format.

@FoxyGrandma915 5 жыл бұрын

Hi Tim. How can you trigger an output after a certain amount of pulses. For example if the encoder is running and I push a button at count 500, I want to turn a light on for 50 pulses after 1000 pulses have passed. Also how can I handle pushing the button a second time before the light has turned on from the first push and still light up the light for both button pushes?

@TimWilborne 5 жыл бұрын

I'm not sure I'm fully understanding what you need. But if I'm halfway following you, you would use MOV instruction with an ONS with a Source A of HSC:0.ACC to capture the value when you press the button. Then an ADD instruction to add 1000 to that value to determine when to start you light. Then ADD to determine when to turn the light off. Then you could use a LIM of these two values to turn on the light. Does that sound right?

@FoxyGrandma915 5 жыл бұрын

Tim Wilborne yes. But what I am wondering is how can I keep track of two or more button presses at the same time. This is for an actual application of boxes across a conveyor. The encoder is on the conveyor and when it senses a box it triggers an action downstream on the conveyor. Before it gets there though, more boxes would have passed that original sensor.

You can make Ladder 3 execute when the HSC reaches a preset value. Say that you needed to do something with precise timing the moment that a value is reach, ladder 3 would interrupt the normal execution of the program and immediately run.

It reads 0 unless im spinning it real fast then it just reads either 100 or 200. The channel is enabled and the current count is working fine. Im using a 60ppr single channel encoder. I have check out all the forums and tried things people suggested who had similar issues but still no success. Any help would be appreciated. Thanks
