  1. Post 2020,  Masks will be mandatory on all communications or 14 day isolation of messages will be required.
  2. Tracking the master clock

    Agreed! Try telling that to these Jokers.  Data collection that no one even uses is more important than keeping your machines shielded from outside influences. They do take security seriously, I am not trying to say any differently.  But the security also becomes the problem in some cases. Also, when I.T. goes to messing around with network settings, and machines start doing funny stuff, it becomes our problem to troubleshoot and fix. I will stop whining now... lol Be Safe out there!
  3. Tracking the master clock

    That did it Joe E.  This is exactly what I am looking for. Unfortunately we do not have a managed switch on this machine.  If we cannot remedy this with a simple change to the device that is taking over as the master, then going to install a managed switch and try to go that route.  For policy reasons, if we were to add a PC the I.T. Dept would have to be involved since it is connected to the Facility network :/.  That usually doesn't end well here. Thank you both very much for all of the help on this!  
  4. Tracking the master clock

    Definitely a better result, but not quite the info I was hoping for.  I am assuming Sint's 0-8 are the Clock Identity. Sint [10] is accuracy, Sint[14] is offset, sint[20] and [22] are the priorities. Just not sure if I will be able to identify the specific piece of hardware with this.
  5. Tracking the master clock

    I tried this exact UDT structure and it gave me an invalid data type error.  I will keep messing around with it to see if I can find something it likes.   thanks again for all the assistance!
  6. Tracking the master clock

    Thank you Joe E.  This looks promising.  I just cant seem to get the data type right.  The GSV returns data when I use a DINT[8], but they are seemingly random numbers.  I have tried to correlate the information, but I do not see any relations to the master clock data.  I have also tried to make a SINT[8](as explained in the instruction help) and store but all I get are 0's in every field.  Other data types are either invalid or again I will get all 0's.  Im not sure what I am missing here.
  7. Tracking the master clock

    We are having issue on a machine running kinnetix 5500 drives where we randomly get clock Sync Faults.  This particular machine is set up as a slave looking to another PLC(L36-ERM) on a different station of the same machine as the time master.  There are about a dozen other PLC's(totally different machines) on the same network and most are set up as masters for their own systems and to my knowledge they have never had this issue. There are also dozens of other devices connected to this network, and then this network is part of the facility wide network.( I apologize if this is a little wordy) We are pretty sure that the slave is finding a more accurate clock on the network somewhere and syncing to it causing the servos to fault. We have tried making both the master, and the local clock of these 2 particular PLC's higher priority than the others to eliminate this with no success. What I am trying to do is track what clock this particular slave is looking at as its master when the clock sync fault has occurred.  is there away to do this through ladder logic?  it seems like we should be able to get this information and save it so we can figure out who the culprit is.
  8. 404 when trying to download updates

    What Browser are you using?  I have had trouble accessing their downloads while using internet explorer V9.   Have you tried firefox or chrome?
  9. SLC 5/04 timer pre

    If the number goes above 32767 a minor fault will occur.  This will throw the processor out of run mode.   To recover from the error, you need to make sure the high value is cleared, and then just reset or clear the fault.  This may only apply to counter and integer registries though. https://literature.rockwellautomation.com/idc/groups/literature/.../1747-rm001_-en-p.pdf Checkout page 43 section 2-7
  10. Help with PLC communication basics

    I have only used Kepware OPC to pull info from PLC's That are not AB for FTView ME to run status displays. I would think a laptop running the kepware OPC server should get the data from the PLC to the Laptop in most cases. What kind of data are you wanting to read? I have ran into a few PLC's(mitsubishi q series) that do not like talking to kepware from their serial ports. Im not sure how this may affect it using ethernet though. Keep in mind that if you are using a Micrologix 1400 you will also need to buy a license for RS500 programing software, download and install to be able to connect to the PLC and program it.(if you know this already I apologize, it was not mentioned in your post)
  11. panel-view plus 600 HMI

    More than likely you will use Ethernet for PC Communication.  you will need to know the IP address of the panelview and set your PC IP address and subnet to match before you will be able to see the PV+ in Rslinx   Cancel
  12. Annoying problem in Logix5000

    In some way, shape, or form the program in the processor does not exactly match the program that is saved on your CPU.  Did you verify your changes while online with the processor and then exit the program without saving? I would save the copy that has the "applied changes" under a different name.  then go online using the "applied changes" program and see if the message appears again.  If not, you can compare the original program with the "applied changes" program and find out where the difference is.
  13. This could be nothing, but I have had occasions, especially using a UIC device. If RSLinxs classic is running, and RSLinxs Classic UIC Driver is running and you can see your PLC's in the RS Who window, Then I was never able to connect to them with RSLinx enterprise in Factory Talk.  I would have to stop the driver, and delete it for good measure(in RSLinx Classic), and then shutdown RSLinx Classic before Factory Talk would see the processor or tags.  Basically, if RSlinx Classic has control over a comport, it will not let any other program access it while it is running.
  14. I had never heard of velocio PLC's before.  Just did some research on them and those things look neat!  Looks like it could be a solid option for a smaller application.  Im sold, I am going to buy one for some home projects just to try it out. But I would be very hesitant about specifying it for a paid project at this time as well.
  15. Studio 5000 and different PLC versions

    The Download files are big.  but once you install support for a version, look it up in your control panel(add/remove programs) and see how big version support file is. Apologies for the poor picture quality. The support files for my studio versions are somewhat highlighted.
