  1. CCW/Micro800 series

    Hello all! I have a two part question - both revolve around using Rockwell's CCW software. 1) in rs500 you can mov a value into the an int memory slot and call that int up later on for comp. instructions to see where you're at. Example, if x switch is active, mov value 0 into N7/0. If y switch is active, move value 1 into N7/0. If both x & y are active, move a value of 2 into N7/0. How is this done in CCW??? I've found the mov command but not sure where/how to store this value. 2) How do does one shot [ONS] work in CCW?!? From what I've gathered the r_trig and f_trig is its replacement, and thought it made plenty of sense. But no matter what I do the triggers never work out correctly. Thanks, -g
  2. Another Dumb newb question

    @Joe E. Got it, thanks a bunch!
  3. Another Dumb newb question

    Thanks @Joe E.. Where do you save that download to?
  4. Another Dumb newb question

    @JRoss Would you be able to send me that AOI function as well please.
  5. Codesys

    @acpi Thanks for that clarification. I guess I am just trying to always expand and delve into different PLCs/PLC programming software (outside of Allen-Bradley) and Codesys seems very intriguing. What is causing some confusion for me (and it is probably because I am very new to the PLC/programming world - so this may be a dumb, ah-ha moment) is what PLCs I can actually program with the software? With RSLogix500/5000 and CCW, Automation Suite by Automation Direct, etc. usually when beginning a project you select/build your PLC - with Codesys it is like a blank slate for whichever programming language you're using.   Maybe there is a video out there explaining this better, most of what I found was just going through actually throwing some logic together though in Codesys.

    Thanks @Kirill for the information. Going to dig into this as I have some 'r&d' time coming up. What is your opinion on Codesys? I was thinking of purchasing one of the above listed PLC's to test it out with.
  7. Using RTC To Shut off Motor

    Thanks @gclshortt, that post gave me some good information and was able to finally figure it out! Appreciate it. -g
  8. Hello - I am currently setting up a program to control a downlane conveyor motor and ran into the issue of operators leaving the conveyor on through their breaks/at the end of the shift.... I know, shocking . Anyways, the essentials of the program are the following - ladder logic, start/stop PB station, a sensor that says when I've seen a box for x-amount of time I will turn off, when the eye is clear for x-amount of time I will turn back on. When trying to 'solve the problem' of the operators leaving them on, I figured this would give me a chance to use a RTC (real time counter) and program it so that at various times of the day I will send a single shot to verify the relay is CT is open. I've enabled the RTC on the Micro810, dropped a TOW but do not really understand how to set the TOW block up. Hopefully that all makes sense. Thanks,  grubb
  9. Codesys

    Hello - I stumbled across some mention of Codesys and was curious if anyone here uses it. Pros/cons? prefer it over other programming software. Have it downloading currently (since you can download a free variation of the application) but it looks quite interesting. Also - what PLC hardware is programmed with it? Did not see that mentioned on their website when I was browsing through.
  10. Weight Scale

    Hello - Not sure if this is the right place, I apologize if not. Just let me know if I need to move it and can delete and do so. But I am currently working on a project where I am collecting seeds (flower seeds, etc.) and when a certain weight limit is met I'll be turning off a vibratory bowl and opening a chute, etc. Looking for some ideas on the scale and how to do that process in particular. The smallest collection weight will be around 100mg, largest around 8g.  Mainly looking for ideas on the scale.  Thanks for any help/tips, much appreciate.
  11. Hello all - Wanted to check in and get some ideas on how everyone else out there stays organized with the various connectors, cables, etc. Currently I have been using a decent sized laptop backpack (keeping my laptop in there, spare battery and charger) along with various cables, connectors, external drive, CDs, screwdriver sets, wire crimps/strippers, etc. Seems though as I've been getting into different projects, different PLCs and such that the 'inventory' has been growing. Just wanted to hear others thoughts. Also, if you could maybe throw out your NEED TO CARRY items I'd be interested in what everyone else has to say. Sorry if this has been posted before or somewhere else. Thanks,  Kyle

    Does ‘run as administrator’ get you any different result?
  13. Controlling Cylinder Stroke Length

    I’ve done some minor programming projects (mostly conveyor systems). And wanted to tackle something new, so all the information/help everyone is providing is greatly appreciated!
  14. Controlling Cylinder Stroke Length

    @kaiser_will thanks for the information; I’d prefer to go with pneumatic or electric controlled cylinder. Must press within a equal to or less than 0.5mm threshold, and will have various settings for stroke length (lets just say 3). So a selector switch to determine three various stroke length set points. Time allowance would not be hateful, whenever the operator is clear (at the proper operating station) to hit the cycle button the cylinder extends to x length and retracts to ‘home position’/retracts. The servo cylinders seem ideal to allow better control from the information you provided, thanks.  
  15. Controlling Cylinder Stroke Length

    @pcmccartney1 thanks for the link, very interesting and going to dive deeper into researching on those cylinders.
