  1. Another Dumb newb question

    You can download the SCP instruction from Rockwell: see KB Tech note 38090 It says it works for RSLogix 5000 version 16 project or greater. I've used it myself in RSLogix5000 v20 and Studio5000 v30 and it works fine. Looks like JRoss uses something like this too.
  2. Preserving FIFO Data

    This is how I do it too
  3. Studio 5000 Task Monitor Comms IO Monitor

    Interesting, last week a Rockwell representative came to my company to do a presentation and said the L8x controllers were "coming soon" but did not give an exact date. (This was in the Northeast US)
  4. Studio 5000 Task Monitor Comms IO Monitor

    I've never used this before, but I found this document online: https://www.rockwellautomation.com/resources/downloads/rockwellautomation/pdf/solutions/integrated-architecture/LogixTaskMonitorInstruction.pdf  
  5. analog flex I/O to VFD

    I would ask this person why they think you need an isolated card. The drawing is a little hard to read. I'm not that familiar with isolated vs. nonisolated, but in my experience: I have mostly used nonisolated cards (CompactLogix) because they are easier to wire. Also I think the nonisolated ones were cheaper (I could be wrong). But a few times we specifically used isolated cards because we knew we were going to have noise issues.
  6. Adding 1756 16 point IO card added as DINT/SINT?

    I just added a 1756-OA16 card to my Studio5000 v30 project, and I got 32 bits too. Local:X:O.Data.0 thru Local:X:O.Data.31. Not sure why either. Maybe call Rockwell?
  7. Question about an AB UPSD

    I have not used this before but based on the user manual here: http://literature.rockwellautomation.com/idc/groups/literature/documents/rm/1606-rm036_-en-p.pdf It says "allowed batteries" are 3.9Ah to 40Ah. I'm assuming the larger the battery, the longer the UPS will last during a power failure. The manual also says that two "accessory" options are available: "two preassembled battery modules are available: a lightweight 7Ah battery that can be mounted on the DIN rail and a 26Ah module that can be panel-mounted for longer buffer times." So the 40Ah may not be a standard option. Hope this helps.
  8. Capturing bits of a dint

    You can use a bunch of counters. Use 1 counter for each fault bit. Each time the fault bit = 1, the counter will count up. After a period of time, the counter with greatest ACC value shows which fault bit triggered the most. The downside is, you have to create 155 counters using this method.
  9. Registering EDS Files

    Not sure, you tried to reinstall RSLogix which is what I would suggest. The only thing I can think of, is sometimes when I try to add a module I can't find it because I type the name wrong. Sounds stupid but it got me confused a couple times. Try to use the scroll bar on the "Select Module Type" window and slowly scroll down the whole list, maybe the modules are there but named differently than you thought.  
  10. CompactLogix Hart

    No, but I have used other Spectrum cards before. I remember I used the 1746sc-NI8u (for SLC PLC's) a couple years ago and it worked fine. Looks like they have tech support info here: http://www.spectrumcontrols.com/support/product-support/
  11. Compactlogix PLC read/write data Excel via Ethernet/IP

    I've never used AdvancedHMI before but their website says their software is free
  12. Compactlogix PLC read/write data Excel via Ethernet/IP

    I watched the video, it looks like this method uses Advanced HMI communication software instead of RSLinx. Sorry, I don't have time to test this method. Have you tried it? If you tried it and can not get it to work, maybe ask at the Advanced HMI support forum here: http://www.advancedhmi.com/forum/
  13. Compactlogix PLC read/write data Excel via Ethernet/IP

    A couple years ago, I read data from a Compactlogix 1769-L32E to Excel, basically using the method in the first link. This method should work Ok with your Compactlogix. I think your issue is, it will not work with RSLinx Lite. Sorry, I can't try your zip file on my work computer.

  15. FactoryTalk SE - VB Script

    Yes it could work. You would need to write a standalone VB application. At one of my old jobs, this was how we did it: CompactLogix PLC, FTView SE HMI, VB .exe application. The PLC communicated with the HMI, and the HMI communicated with the VB application. There was some "heartbeat" logic to make sure that communication was not lost. Not sure of the details because I never worked on the VB application personally.
