  1. Hey all,  So I am looking for some assistance because I am not understanding how the tags on an HMI and within a PLC are linked. There are no 'physical' buttons, just what is on the HMI. It is controlling a chiller. Communicates over Modbus TCP/IP. The PLC is an IDEC. I have some-what worked out how other tags are working when they are words being passed back and forth, but this one has me stumped. I've attached a few screenshots for referral. It looks like the run and unload buttons for the chiller are a single bit/BOOL toggle (but the chiller running latches itself in the PLC when the chiller starts to run). The stop buttons appears to be a parent for the single bit/BOOLs and when it is pressed it resets them all both on the HMI side and within the PLC side.  
  2. Hey all - I am working on a car wash system design that will utilize the Nayax payment system. Has anyone utilized them? How do I incorporate the device with PLC to automate the system. After payment is approved how can I send out that signal from them, all via ethernet on a managed switch w/ wifi for exterior comms for the Nayax.
  3. Thanks @TimWilborne, I'll be giving this a try and get back to you!
  4. Hey all - I am stumped and looking for some assistance. I have a project in studio 5000, v.32 where I have some ABB drives that are not recognized. I've installed the EDS files, exact same one my co-worker besides me did, and mine will not go recognized and it is driving me crazy! I've done it while online with the PLC and offline, still to no avail. I've also installed the EDS files by going through Tools>EDS Hardware Installation and by right-clicking on the ABB drive in the controller organization tree and registering EDS file. Thanks for any assistance, -k
  5. 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
  6. @Joe E. Got it, thanks a bunch!
  7. Thanks @Joe E.. Where do you save that download to?
  8. @JRoss Would you be able to send me that AOI function as well please.
  9. 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.
  11. Thanks @gclshortt, that post gave me some good information and was able to finally figure it out! Appreciate it. -g
  12. 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

    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.
  14. 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.
  15. 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
