  1. Analog Wiring NO NO

    I prefer forks over bare wire myself. I also prefer spring cage terminals over screw.  The spring cage has been well proven. I have 18 years of hands on maintenance in pretty harsh conditions. I have solid experience as to what works and does not work.
  2. Analog Wiring NO NO

    Whats wrong with this picture?  What could go wrong?  This is how my employer wires analog circuits in the panel! #Frustrated Employee!! #EPIC_ANALOG_FAIL    
  3. Analog Wiring NO NO

    Your picture is the way I do my analog wiring as well.  As far as the Ferrells vs Forks.....I have no clue why the builder did this????  In fact they should not be using ferrels at the cards as they are designed for forks or rings only.  Ferrells should only be used for terminals. The quality of the cabinets defiantly has room for improvement.  I make suggestions but why listen to the new guy with 15+ years experience when you can keep doing what you have been doing for the entire year you have been in the business!

  5. Analog Wiring NO NO

    The analog cards should not be wired with individual TW conductor.  They should be shielded 2 conductor wire, or 8 conductor shielded, regardless it should be shielded. I also prefer Rockwell but the company standard is OMRON since they don't charge for tech support.  Have to agree with the company on that point. The digital cards have Ferrell and should be forks.  The Analog cards have forks however are too large. I see opportunity to start my own company as I have higher quality standards!
  6. Wire labels

    Guess no one has a sense of humor??
  7. Wire labels

    Yes, do not go to work drunk, hung over, or high and then labels should be straight. 
  8. Flashing Bit

    For the life of me I cannot figure out why a particular bit keeps flashing even though the logic ahead of it stays true????  I have tried different registers to rule out crossed memory registers and still get the same effect.  I have also tried going around all my compare logic with no effect. Any ideas?   Flashing Bit.mp4
  9. Flashing Bit

    Thanks for the reply and suggestion.   I will give it a try however I went around the logic driving the bit and it would still flash. Stay tuned for updates.
  10. PLC 5 CAD DWG's

    Hello group, does anyone know where or have PLC5 CAD drawings?  The Rockwell site doesn't seem to have them anymore.  All I need is a processor, an input, output, AI, AO card, and a rack.  I am doing a drawing up and want to reflect the processor as more than a square. Thanks
  11. Description Entry

    With Rockwell you can easily and quickly develop I/O description in excel using a CSV file. Does CX Programmer have a similar feature?
  12. ZCP Instruction

    Hi group! I am struggling to figure out what I am doing with the Limit instruction (ZCP 088).  I want to turn on a permissive if the compared word is between 1 and 12.  Rockwell makes this so much easier!!! It looks like my "=" instruction is not correct but this is how they show it in the manual???????    
  13. ZCP Instruction

    If this is the way to do then why does OMRON have the ZCP instruction?????
  14. ZCP Instruction

    Thanks!  That did it.
  15. FIFO

    Yes, the data is shown on an HMI and an operator will question it if they have no items in that location yet it shows on the HMI.
  16. FIFO

    I am using the 663 FIFO instruction which is functioning properly as it loads, however when the stack is unloaded the FIFO does not set the last number to 0.  Looking at the instruction for the FIFO it seems that this is how it operates. Is there a way to move a 0 into the stack as the values are being unloaded? Example: I have the following values in my stack: 217 223 224 109 When I unload the FIFO my value changes to 223 224 109 109 And if I unload again it changes to: 224 109 109 109 I want a zero till fill in the last spot as the FIFO is unloaded. 224 0 0 0  
  17. New to OMRON

    Hi group. I am trying to improve on an existing program however I am not very familiar with OMRON. I am programming an OMRON CP1H using CX Programmer V.9.6 I would like to display an alphanumeric display on a Proface HMI.  I would like the display to show different text based on a user input.   In the screen shots below a user would load a battery into a specific row/column, I will call it a "slot".  The way the program is now the FIFO would load for example the number value 2009, which illogically represents "Row 2, Column 4, which would be slot 9. How can I program a text display to say "Row **, Column **, Slot ** ?  Seeing 2009 in the FIFO stack makes no sense. The images below: 1 - Current Logic that generates the 2009 based on row and column selected.  In this case Row 2, Column 4 would equate to slot 9. 2 - User input screen 3 - FIFO stack based on how the battery was entered.  In this case 2009 would go into the FIFO.  If the operator then loaded Row 1, Column 1, the next number generated would be 1001 (Row 1, column 1.  
  18. FIFO

    Are you a mind reader????  This is what I was going to try lol!
  19. FIFO

    This worked pretty well. Thanks! Any advise on how to add text to a numeric value? Example......I have the number 224 and I want to add to it text to say 224 Right, or say 224 with a right arrow indicator that would light up if this is the side the 224 was from.  Trick is it needs to remember when it comes time to unload from the FIFO as to whether it was Left or Right.
  20. FIFO

    I think i understand what your saying, I will try that.
  21. New to OMRON

    Thanks, I will have a look at this.
  22. COMPACTLOGIX MOTION WITH POWERFLEX DRIVES CRANE APPLICATION

    We had the same issue with sway.  We ended up hoisting all the way up.  We also had locating/locking guides to help reduce sway.  Either way, sway became an issue when lowering near the stack as the cables became longer and more prone to movement.
  23. COMPACTLOGIX MOTION WITH POWERFLEX DRIVES CRANE APPLICATION

    While at a previous employer we did crane automation and the PowerFlex 755 was what we used for each axis.
  24. Temperatre Sensing

    Does anyone have any suggestions for a simple wall stat do send a discrete input to a PLC based on a desired set point?  I am thinking of a simple line stat and using the contacts to send a discrete input to the plc.
  25. Home Lab

    Just curious if anyone else has built a home lab to experiment and work with?  How did you decide what was going to be included?  Did you just mount your equipment on drywall, plywood, or an actual backplane?  Anyone have pictures.   I want to build one to learn on.  I want it to include the following: actual 30 X 30 backplane PLC with Ethernet coms. HMI Small VFD and or stepper motor Maybe a remote rack as well Remote access cabability And what ever else I can fit on my back plane.  I already have various sensors to use. I also have a ScadaPack32, OMRON CQM1 (no software though), and a Direct Logix PLC. I also have a couple SEIMENS LOGOès but again no software.(I could program them from the onboard screen) I really want Rockwell hardware but the software is just to expensive!
