  1. Looking for programmer help

    Just sent a PM to you with a suggestion.
  2. Kinetix 6000 AM E75 error

    Steve: Ha ha!  Obviously, I did not notice that.  I saw the recent replies and went along for the ride.  I didn't translate John Carvajal's message until you posted the age issue.  For anyone interested, an online translator offered this translation of his post: "It may be dust or moisture on the bus's chassis, please download the drive and blowing the backplane. Once the drives not passing 2 and became a cleaning and now everything is ok". Well, maybe it can help someone in the future...
  3. Kinetix 6000 AM E75 error

    Intermittent high bus voltage faults when not in motion can also be poor grounding.  I have seen this a lot on variable frequency drives.  On the Kinetix platform, faults are cleared when powered down.
  4. Keyence Lasers

    You sent me info stating that you are using the IL 100 with a 1768-L43 CompactLogix and were asking about an EDS file.  First, the IL 100 is just the sensor from what I see on the Keyence website.  It looks like there is an amplifier that should go with it, an IL1000.  When I looked at the info for that module, it looks like it has standard digital outputs for pass/fail and an analog output for measurement.  I do not see a network option that would require an EDS file.  What is your plan for interfacing the sensor to the PLC?  I am not an expert in this particular sensor, but these are the things I see.  
  5. Keyence Lasers

    It would be helpful to know which Keyence laser (and controller) as well as the PLC manufacturer and type.  Don't forget to tell us how the plc will get the values from the laser (analog signal or communication network).  It might be helpful to explain a little about your application.  There is a lot of experience on this forum, but we need details in order to provide the best help.
  6. allen bradley panel troubleshooting

    I agree with PLCMentor- we need to know exactly what is "tripping".  Is it the whole cabinet or just the plc?  If the problem is intermittent, it may require you to monitor several things with a meter that can record the values against time.  Is your PLC powered by AC or DC power?  I would monitor the incoming power, any DC power supplies and try to relate that to what is happening in the process when the fault occurs.  If your main power is staying up, but your DC supply is dipping, then it could be related to a load that is putting your power supply into a current limiting protection mode.  If your AC power is not consistent, try to relate when the fault occurs to the time of day.  Are other machines having the same problem?  Does the fault occur at the same time(s) daily?  If so, it could have to do with how your neighbors are using the power or it could also be the power company inserting or removing correction capacitors to manage the power factor.
  7. Programation problem

    It depends on the equipment that is doing the control.  You need to look at the individual pieces and determine the manufacturer and model before the software can be determined.  Are these machines already built?  If so, then what is the manufacturer of the controller, drives and human machine interface (if any)?  RSLogix500 is the software used for Allen Bradley's SLC and Micrologix programmable logic controllers.  I also don't understand something:  you mention two motors, but three variable frequency drives.  I have seen multiple motors controlled by a single drive, but not vice versa.
  8. RSView32 not toggling bits in RSLogix500

    You should also put up a screen shot of the button configuration as well.
  9. Master-Slave Equipment Protocol

    Often times, nobody thinks of the handshaking signals between equipment until the programmer(s) get involved.  I learned quite quickly that the mechanical engineers or salespeople or the process engineers involved with the equipment will have SOME idea of what is needed, but it is the programmer who will know exactly what is needed.  After getting put into tight situations in the past, I learned to insert myself the process early and state my requirements for I/O and handshake info.  I would often have to plead my case when I first started out, but after proving myself , it is much easier now.  So, the response you got to "sort it out on your end" is quite normal.  What you would do to "sort it out" would be to develop a list of the signals you need and then determine how you will get them (order from machine vendor, outsource or just do it yourself).  If you are a programmer only, without resources to design and install the additional hardware, then you would need to find another source to add the necessary I/O.  Ultimately, the programmer may have to compensate for shortcomings in mechanical or process design, so it is best to be assertive when telling others what you need to make the project successful.
  10. E300 led marking/titles

    Again, Inntele has the answer.  I have not used the software in over 15 years.  I knew there was something out there, but did not realize (or remember) that it was in the design software.  Thanks for the update, Inntele.
  11. E300 led marking/titles

    Inntele has it.  It doesn't get any simpler than that.  I thought I remember seeing (many years ago) a template for filling out those strips, but I could not find it just now.  I remember using the trial and error approach to creating my first strip.  You will have to create your legend, print it, compare it to the size and available space for each LED, then adjust.  Repeat as necessary.  Good luck.  The Beijer terminals were always easy to use and robust in my past experience.
  12. Project cost tracking

    I have done it both ways.  I have placed orders for the components for one machine and then simply copied the requisitions in our purchasing system.  This was helpful to our accounting department, as well.  I have also placed one large order where you simply divide all of the quantities (and costs) by the number of identical machines being built.  For machines that are not identical, it is easier to track if you issue separate orders for the components for each individual machine.
  13. Project cost tracking

    We use an Excel spreadsheet.  We have several rows that explain the breakdown of the budget (mechanical, purchased equipment, electrical, outside services, etc).  Then in the columns, I put the dollar amounts budgeted and the actual spend.  I calculate a running total to show where we are in the budget.  Another helpful thing is to add a column with the PO number and an explanation of what was purchased, who purchased it and from what company.  That way, if you have overruns, you can quickly look back at the chart to see where your money went.
  14. GX Developer

    To help clarify:  If you need the software to communicate and program your device, you will need to contact your local distributor of Mitsubishi automation equipment.  For Washington state, it is: BUCHANAN AUTOMATION, INC. 1920 Bickford Avenue Snohomish, Washington 98291 800-426-8313 For more info from Mitsubishi, you can check out their website:  https://us.mitsubishielectric.com/fa/en    
  15. 1769-BAT + 1769-L32E

    I will second IndeckTech's statement.  We had problems with the processors losing their programs w/o notice even with good batteries.  It was firmware related.  If I recall correctly, there was even a KB article on A-B's website about it. It was some time ago that I had the problem.  The firmware levels involved were 15 and 16 and the KB article numbers are 45709 & 38430.  There was another issue relating to the type of memory that was used on the device, but I think that problem was with communication cards, and not the processors. Kaiser_will is also correct when he states that a good PM system must be in place to replace old batteries.  In the case of the problems we had, the batteries were only a couple of weeks old when we were losing programs.  This is what led me to find another cause.  Please let us know your resolution.  Cheers.
