  1. 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.
  2. 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.
  3. 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
  4. 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.
  5. 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!
  6. Expressions

    Thanks Ross,    I ended up using yours as it is simpler with the same result.
  7. Expressions

    Yes, this was a last resort.  Being new at this I wanted to conquer my first expression.  Going to test it out now.
  8. Expressions

    It is a DINT  
  9. Expressions

    I seem to have gotten it to work using: If {::[Process]Program:Boilers_Main.LV_36101_New} < 3  Then 0  Else  If {::[Process]Program:Boilers_Main.LV_36101_New} >= 3  AND {[Process]LIC_36101A_PIDE.Auto}  Then 1  Else  If {::[Process]Program:Boilers_Main.LV_36101_New} >= 3  AND {[Process]LIC_36101A_PIDE.Manual}  Then 2 Else END
  10. Expressions

    The HMI can read the tags as I am editing a running system.  It was a simple 2 state Green for open and Grey for not open expression.  The trick is adding the 3rd Yellow for indication that the valve is in manual.  
  11. Expressions

    Yes I have tried a different updated expression and this would be why the 2 did not match. Currently have   If {::[Process]Program:Boilers_Main.LV_36101_New} < 3  Then 0  Else  If {::[Process]Program:Boilers_Main.LV_36101_New} >= 3  AND {[Process]LIC_36101A_PIDE.Auto}  Then 1  Else {::[Process]Program:Boilers_Main.LV_36101_New} >= 3  AND {[Process]LIC_36101A_PIDE.Manual}  Then  2
  12. Expressions

    Hi forum members!   I am spinning the wheels on trying to get my expression to validate.  I am new to expressions so after trying for a bit I have thrown in the towel and am looking to the experts here to help me out. As you can see with attachment I am trying to change the color of the valve top hat.  I am needing 3 colors: Gray when closed, Green when open and in Auto, and Yellow when open and in Manual. I was asked to not change the PLC logic as this could be done from the SCADA level.. After looking at my application and attempt do you have any suggestions on what I am doing wrong?    My Expression:  If {::[Process]Program:Boilers_Main.LV_36101_New} < 3  Then 0  Else  If {::[Process]Program:Boilers_Main.LV_36101_New} >= 3  AND {[Process]LIC_36101A_PIDE.Auto}  Then 1  Else  Then  If {[Process]LIC_36101A_PIDE.manual}  Then 2
  13. Hi group,   I am trying to return an activation that I believe was left on my VM when I deleated the RS Logix software. I have reinstalled Activation Manager to see if I can return the activation. (The activation list from the server shows my VM as having an activation and expires next year!  Thats why I need to return it so other workers can use it.) In the attached images is the LIC File the license and if so why would it not be seen in Activation Manager?  How do I go about returning this if it is a borrowed license?    
  14. Upload AddOn Fault

    I noticed that the title says 20.13 but in my previous screen shot it is 20.11.  Does this mean that I have 20.03 and am trying to upload a 20.01 version?    
  15. Upload AddOn Fault

    I use to work for the company that developed the program and also have the program from this past summer.  I also verified with them what version is still on the PLC.  I am thinking it is something on my end.
