  1. It's getting harder for me to keep up to date on new innovations in the industry, but this week I was at a Neff Expo in New Jersey and I saw this Murr Mico Pro. Is anyone else using this product in their panel builds instead of traditional circuit breakers or fuse block holders for 24 VDC protection? Looks like a really neat product to try. https://www.murrelektronik.com/products-p/detail/electronics-in-the-cabinet/mico-proR.html
  2. on the allen Bradley  QandA there is a broken link to the AB KB in one of the answers.

  4. Good evening, do you know how to download RSlinx GATEWAY?
    why I want to do the communication of the labview with RSlogix 500 via OPC, except that RSLLX classic lite does not do this type of communication.

  5. Interacting with QCPU Registers from LabVIEW or Raw TCP

    This is my FAVORITE TOOL in my backpack. http://www.midbittech.com/ Shark-Tap It works with Wire Shark no problems. I have solved alot of problems with this, from Ethernet/IP, to ASCII over Ethernet, to Modbus commands, to just about anything that passes through my Shark-Tap box.
  6. Webpage View and Excel Sheet Updating

    Is there any new software out there that can connect to QTY (16) Compact Logix PLCs via EIP, and setup a nice dashboard from each PLC a few tags that a person can hit an internal ip address to view the dash board, and then can that data be saved to an excel sheet or written to an excel template? Just wondering if anyone has developed some new stuff that can do that.
  7. Hey Chris!

    I'm new to the site and seen that you had posted to help someone with PLC programming estimating. Looks like you had linked a file " plc_estimate.xlt " but I can't seem to click it myself.  Is this something you could share with me? I'm also looking at trying to get some estimating done.  New to it as I've only worked hourly but I was thinking 1.25hr/point in use and 0.25hr/point not in use (I pre-program points not in use as well for future use).

    Anyway anything would be helpful.

    Thanks

  8. Has anyone found an "OK" drawing software that is FREE that works for electrical drawings and can generate DXF or DWGs? I am trying to recommend some software to some kids I know that want to start to learn how to draw. I know AutoDesk offers educational software versions, but we both are looking for something a little bit lighter weight out there. Any recommendations you guys have stumbled upon?
  9. AB PLC Firmware or Hardware Producer/Consumer Limits?

    Ken and Joe. Thanks. Ken, good pointer what to check.
  10. I have old Siemens program. In that DB952 is used for 2D barcode scanner data. Previously Barcode was only 10 letters but as per Customer requirement new Barcode is 12 letters. Now if we scan new Barcode with existing program it gives #####error on HMI. When I checked it I found in PLC program in DB952 STRING for barcode scanner data is defined as [10]. So now I want to increase that STRING Length so that I can scan my new Barcode with 12 letters without any error.
    Please help me.....
    Please see attached picture of my DB952 where STRING is declared.

  11. Does anyone know if there is a firmware or hardware compatibly issues with producer / consumer tags? I've run into an issue where a newer PLC (version 28.0) works fine with Producer / Consumer tags, however and older (version 16.0) PLC doesn't seemed to want to work. I am trying to chase down the firmware trail and see if there is a compatibly matrix or hardware matrix somewhere that lists some limits or "not support" somewhere. Is anyone aware of such a thing?
  12. Allen Bradley SLC 5/04 PLC  When i turn it on the FLT light flashes Red and battery LED also solid on. i need help
