  1. Interesting...I'm not sure if I have that problem or not, but my test bench 1769-L33ER (v34.11) is 2.5 hours fast right now. It's been a while since I checked the CPU time, so it may have been drifting for a very long time.
  2. Communication PROFIBUS(master) + MODBUS(slave)

    Well, there I go not spending enough time reading the details...
  3. Communication PROFIBUS(master) + MODBUS(slave)

    Isn't that for a Profibus slave? OP wants to connect a Modbus RTU Slave to a Profibus Master
  4. Communication PROFIBUS(master) + MODBUS(slave)

    No personal endorsement, but I've seen other products from Anybus that seemed solid: https://www.anybus.com/products/gateway-index/anybus-xgateway/detail/anybus-x-gateway-profibus-master-modbus-rtu-slave Do you think that one might work? I checked ProSoft first but they only have Profibus to Modbus TCP, not RTU.
  5. Tia Portal Program Upload Error

    What version of TIA Portal are you using? Do you have WinCC Basic? I don't have that software any more, but I do remember it being version sensitive. But that may have changed with newer versions.

    Here's just lad 2. It printed the whole thing when just doing an individual ladder file. MTVAC35_Lad2.pdf

    That's crazy. The preview shows all rungs, and I could have sworn I double checked the pdf but it's not there.  
  8. I think you're going to have trouble with that distance. Just as a reference, I pulled up the guidelines for Rockwell drives (because they're handy) and the max distance they support with filtering varies by size and series of drive but maxes out at 365m or so. https://literature.rockwellautomation.com/idc/groups/literature/documents/in/drives-in001_-en-p.pdf   Your distance is almost 6 times longer than that. Definitely reach out to your drive manufacturer for guidance. You may end up having to build an enclosure near the pond for the drive.

    Try this. "Microsoft Print to PDF" is pretty awful, it seems. Some pages ended up missing and the file size always seems huge. MTVAC35.pdf

    Hmmmm, that is weird. I told it to print the whole thing but it looks like it didn't work right. LAD 2 has 140 rungs. Let me try again with a different print driver.

    I just took the ".com" off the end and it opened. No symbols or comments, though. MTVAC35.pdf
  12. 1794-AENT Setup Issue

    I generally find myself using IPAssign from Phoenix Contact more than AB's Boot/P. It tends to work well at assigning the address. I then use RSLinx to disable DHCP.  
  13. 1794-AENT Setup Issue

    Thanks for that info. It seems a little crazy that the BootP tool has to be upgraded. Shouldn't it just be supplying IP addresses? Maybe the command to disable DHCP is special...
  14. We ordered 9324-RLDMLPE, the Multi-language pack that licenses use of ST, FBD, and SFC. It's an add-on to the standard edition license that lets us use the other programming languages. There may be something you can order to just get ST, but I'd probably just get the multi-pack. You'd have to reach out to your local distributor to find out. You'll need to talk to them for pricing anyway, and AB's licensing system is messy enough you'll want expert assistance getting the right thing.
  15. A couple of times, I had to wait a bit and try again when attaching multiple files.
  16. The manual itself doesn't provide much info but it links to an Excel spreadsheet with a little more info: https://literature.rockwellautomation.com/idc/groups/literature/documents/rd/2198-rd005_-en-p.xlsx For "NODE FLT 02 – PROC WATCHDOG nn", the spreadsheet says:    
  17. Micrologix 1400 PLC

    Some faults will cause the PLC to erase the program in memory. Without going online with the software while the fault is active, it's hard to be more specific. The 1400 has an LCD screen where you can navigate to "Monitoring" and select file #2, which is processor status.  You can then look at individual words. Word s:6 is your major error code. I've never used the LCD to diagnose an issue since it's easier with the software so I don't know if the LCD still works when the processor is faulted, but that's where I would go if I didn't have a license.
  18. I found a comparison tech note (access level: everyone) that compares them: https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/1032455/loc/en_US#__highlight It doesn't show a difference that should affect trending, but there could be other things different. There's another more detailed comparison document here: https://literature.rockwellautomation.com/idc/groups/literature/documents/sp/2711p-sp011_-en-p.pdf That one also doesn't mention trending or datalogs.
  19. I've worked on machines with the Banner safety controllers and have done upgrades on machines where we used Keyence. In general I prefer Keyence over Banner but I wouldn't be upset to work with either. We have other machines with Schmersal and ABB/Jokab controllers. The Jokab are ok but the Schmersal are kind of a pain, especially if you're not absolutely fanatical about keeping up with your source files. You can upload out of them but only a compiled runtime to transfer back into another controller. To monitor/edit you need the matching source file. In the AB world, they also have the 440C-CR30-... controller that's programmed in CCW (free) or can be embedded in a Logix project. I found them to be useful but their IO is very limited for the price and can't be expanded (with safety IO).
  20. High Pressure PID Control

    I'm not super experienced with valve actuators, but 5% mechanical backlash seems like a lot to me. Can that be tightened up at all?
  21. That's what I suspected would happen but I haven't used ADC before (heard "horror stories" from a colleague about the firmware versions having to be perfectly aligned and we very rarely had to replace one, so didn't seem worth it). I guess I expected that ADC would be contained fully within the Logix controller and wouldn't affect a disconnected drive at all, which seems to be what you found as well with your experiment. So basically, with the network unplugged, the drive parameters set to factory default, the STO satisfied, and all inputs disconnected except input 1....the drive should respond to HIM keypad control. I would think, at least...
  22. Wouldn't a factory reset clear any ADC setup in the drive?
  23. So, F059 is "Safety Open". Terminal 4 is a DC Common. It's probable that the system is using an external 24V supply and the drive's terminal 4 is connected to the system's 0V so S1 and S2 can use the system's 24V source. Lifting the wire on terminal 4 causes S1/S2 to lose their 0V reference and show open. Btw, that confirms that the STO function is not what's keeping your drive from running via the keypad. Have you tried to set P046-P051 back to their default values and t062-t068 to 0 "Not Used"?
  24. May be a long shot, but are any of the digital inputs (other than terminal 1) wired to anything? I've seen weird things happen when an "unused" input was on.
  25. Also, CCW is a free download from Rockwell. It's a very large file, so make sure your connection is good.
