In this video we are going to go over the CTU Count Up Counter and CTD Count Down Counter instructions that can be used by the Allen Bradley Micro800 PLC line in Rockwell Automation's Connected Components Workbench software. This includes the Micro810, Micro820, Micro830, Micro850, and Micro870 PLCs.

Hi Tim, great videos! Is there a way to not have the text for an input crammed into the symbol? I've tried having the Alias selected only, but this leads to issues with editing/viewing timer PTs etc?

@TimWilborne 2 года назад

Yes, it is a little tricky when it happens. Right click the shortcut to CCW and select properties, then compatibility, then it is one of the DPI settings.

Why numeric data entry with decimals are LREAL? Is possible to introduce a number directly as a real? I mean without using any to. Thank you.

@ethangarrett4193 2 года назад

Sir, do you know if the Micro 800 platform is capable of importing tags from a 750 or 525 series Allen Bradley drive the way a Compact or Control Logix can?

@TimWilborne 2 года назад

Hi Ethan, not sure what you mean by import tags from a Powerflex. Do you mean as in the tags that appear when you add a Powerflex to the I/O configuration? The easiest way is to program a User Defined Function Block such as in this lesson. twcontrols.com/lessons/control-an-ab-powerflex-525-drive-with-a-micro800-micro820-plc-with-a-user-defined-function-block

Great video as always. What can CU bit do? Can not understand 12:42 , "instead there are ten things again " part, Thank you very much

@TimWilborne 3 года назад

The CU bit is a "storage" bit so that the counter knows that it has already counted the current false to true transition.

@memoriosortiz3615 3 года назад

Great video! I have one question sir! What if I want to select (from the screen) a value and this pass to the preset of the counter? Good bye from México

@TimWilborne 3 года назад

Hi Memo. I have a video coming on this in our HMI series but you will need to create two tags. One is a DINT, lets call it DintPre, and another with a type of TIME, lets call it TimePre. Set the time in milliseconds in your HMI to DintPre. Then use the Any_to_Time instruction to convert this to TimePre. The on your timer, put the TimePre in the PT. I hope that helps Meme and good luck!

@sudhandiramanisundaram4909 3 года назад

Hi , Could you please advice counter values (Preset & Accum) can be use DINT - can be use for compare comments, Appreciate your help thanks

@TimWilborne 3 года назад

Great question. then preset and accumulated values are in the TIME format. You can use the ANY_TO_DINT instruction to convert it to a DINT

Hey Tim, I am trying to write a value from a T4T HMI "Numeric Entry" to the "CTUD_1.PV" preset value but it gives me a "Illegal access to function block instance parameter" fault. The data types are the same, DINT, on my MOV instruction. How do I use the HMI to set a counter preset value?

@TimWilborne 2 года назад

You wouldn't use a MOV, you need to assign that tag...such as myHMIPreset...to the counter preset.

@gregmyers8011 2 года назад

I want to enter the PV value from the HMI. Since I can't browse tags, like FTV, what is the shortest easiest way to get a bool or numeric value to and from the HMI.

@TimWilborne 2 года назад

This series touches on that. twcontrols.com/allen-bradley-panelview-lessons

@gregmyers8011 2 года назад

Hey Tim, I tried sending the CTUD_1.CV to the HMI but no luck. I need to know more about the data structures of the micro800. I have a little trouble getting what I need to and from the HMI. I have to admit...I am surprised that A-B made a low cost product that is very useful.

@TimWilborne 2 года назад

Open up the Local Variables for that program and you will see the counter, a CTU would default to CTU_1. Open it up and you will see all of the data structures, the CV is a DINT.

@kadreanhasford5911 3 года назад

How do I make the count go up if I'm using a simulator? I don't have a physical button that corresponds to the counter like that. I tried clicking on the counter and that doesn't do anything.

@TimWilborne 3 года назад

You can toggle the inputs on your simulator. See if this video helps. twcontrols.com/lessons/how-to-use-the-allen-bradley-micro800-simulator-in-connected-components-workbench

so far on these exercises my controller keeps getting program time exceeded the watchdog timeout value fault. code 0x0000.

That is strange John. You are just using the counter instruction?
