  1. I am working with the V15 RS5000. It keeps crashing on me. Usually when I am either editing in the Tags section or importing tags. I am running win2000. Never had this problem before. The tags will import with 0 errors then is gives me the saving error data message. I look in the file and More...(drag mouse)Bookmark PageForwardNext TabPrevious TabClose TabBackToggle Bookmarks Wed Jan 10 11:07:31 2007 Fatal Error!

  2. What is the settings you have for the connection parameters? What did you select for the ethernet device in RS5000?
  3. I agree. Usually numbers running up and down mean noise(AC) or other. Are you using shielded cable? May require isolators.
  4. Ethernet Networking

    Without digging real deep into how large the plc systems are or the specifics of transactions and drivers I can offer some basics things to look at. RPI's or tag update times. Ensure that all items have update intervals that are not all set at the same times or multiples. Use prime numbers. Set items that don't need frequent updates to longer times. Default on I/o can be 20ms. Just because you can doesn't mean you should. I have had devices set at intervals and every couple of hours I had a comms storm and then everything locks up. Drivers. I have seen some third party drivers cause comms irregularities. In controller properties under the advanced tab. You can adjust the time slice the processor devotes to comms or use a fixed amount for comms. This needs to be adjusted and watched to ensure no adverse effects occur. I have used this in systems with large communications overhead and minor control requirements. Download some freeware like wireshark and monitor the packets and see what is causing you delays. It takes patience and then more patience. If you can break the network and watch the comms packets. Basic troubleshooting can apply by halving the network. You could be surprised that some unknown device is causing you grief. I have had operators plug in computers and ethernet loops into unmanaged switches cause all kinds of grief. Good luck
  5. automation direct

    I have used them for simple applications. The math functions are a little rough but you can do allot with them. I use the drop I/O like their tech support. I love their screens.
  6. Yaskawa

    I have specified and used them many times. They are easy to set up and solid running units. I have some working in really harsh environments and they just keep working. Can't say the same for AB or others.
  7. Strange Ethernet/IP "blips"

    All ethernet switches and hubs are not alike. I have learned, the hard way, that you should test them off line. N-tron is a solid product and reliable and my experience with sixnet from the past was not a good experience so I won't comment as I have not used them for years. The best way to trouble shoot is using a managed switch. Take a diagram of your network and look for bottleneck points. All devices should be configured for a fixed transaction speed and not auto-negotiate. The fixed speed should be the slowest device on the network. Place the managed switch such that you can monitor most of the transactions and look for the device that is generating the most requests. The switch is one place I would look first. Then have you performed any software upgrades? Look at the update rates on the devices. See if something has changed. I redownloaded the program to a L61 and lost the RPI settings so check those to make sure they haven't been changed or lost. This is general testing I have used. Some may or may not apply and without a hardware layout and configuration settings it is dificult to point you in a specific direction. There are some monitoring software you can get online that looks at packets and transactions. Some have costs. Good luck as AB ethernet is not easy to troubleshoot and may take some time and patience.
  8. Without knowing the number of devices and brands, or if you plan to expand the system, I would say no. Allen Bradley Ethernet is marginally deterministic and the more units you place on the network the more difficult it becomes. Mixing this with other devices such as Operator interfaces and such devices, especially if they are not AB devices it becomes worse. A Managed switch can assist with predictability, again is device, and transaction dependent. Depending on the control logix you are using and the Ethernet card there are additional limitations. Your best bet is device net or control net. That is my 2 cents
  9. Cimplicity controlling redundancy between 90-30 PLC's

    It has been a while since I dealt with Max-on so here goes. Switch over time is a function of the amount data that is mapped in the max-on software configuration. Volume Dependent More data = longer time to transfer data. Max-on has no overhead as it is a separate software that creates the files that are part of the code downloaded to the PLC's. Typically the scan time impact is minimal but the network time is again Data dependent and based on the configuration of the amount of data and the rates selected. My recollection is that the code determines the primary. You might be able to set the ladder logic to not switch back to primary. I always treated the GE 9030 series as Primary secondary system. I would test this before trying it tho. I have found the 9030 hot back up system to be finicky to get it set up but works well once completed. Hope this helps you.
  10. Registering an old copy of VersaPro

    I think you will have difficulty here. I would just reinstall the software every four days. The way to transfer a license is to go to new computer and create a license transfer disk. Then go to old computer and transfer license and it will place the license on the disk. Then go back to the new computer and move license. Without the original computer you are stuck. Your remaining option is to convince GE to activate an out of date non-supported software. I had no luck with this in the last two years. I have just imported the programs into Proficy software Cleaned up the documentation and moved on. There were features of Versa pro I missed . Oh well.
  11. L63 Losing its program

    Had a problem once like this. When they installed the cabinet and drilled the holes in the enclosure the electrician did not cover the PLC. The PLC and cards had metal shavings inside the cards. I had to blow all of the cards out and the problem went away. Something was either loading the power supply internally, down in a way that defeated any battery backup or UPS.
  12. VersaMax Expansion IO Not Being Scanned

    Silly question. Which side of the expansion rack did you plug the cable into. It does make a difference.
  13. This may be a long shot. I had an issue using Ge screens(Cimplicity) and found that the touchscreen driver was updating based on what the screen was currently showing and some other random factor GE could not explain. never mind I had remaped all of the data in CLGX to prevent this. The long and the short was that GE was not optimizing the transactions and so every request to the Control logix was different and not optimized. The Control logix Ethernet card could not buffer the data ahead of time based on a repetetive transaction and so there were delays getting the data off the back plane and routing it. Bandwidth had little effect. To discover I started pulling users off the circuit until the comms stabalized and then added them back to narrow the search. GE's driver was part of the issue. This was two years ago and they may have patched it by now. What I found was the control logix ENBT card supports both AB CIP and AB ethernet transactions and the combination of both plus changing requests on the same network slowed everything down, and I am not sure if IFix allows prioritizing transactions or has set updates. Good luck I have felt your pain and it is not fun. Keep fightin
  14. Without knowing which Siemens you have it is difficult to know which protocol. I have had good luck with protocol conversions with these guys http://www.prosoft-technology.com/
  15. I have an application that requires load cells to weigh a liquid. It has been many years since I had to do this. What is the best way to an AB PLC. Millivolt card or load cell with 4-20ma out. Who do you recommend as a supplier of load cell hardware. Thanks
  16. load cell to PLC

    Thanks for the input.
  17. Proficy

    You have to be carefull if the old application is a hotbackup using Maxon. This requires tech support help and some experimentation. Beware! before converting to the new software.
  18. Should not be a problem. First make sure your RsLinx is up to date. Second make sure that the ethernet port on your PC is set to an I/P address not used on the network but similar with the same class of sub net. If you are going direct you will have to use a cross over cable. I have had issues with this way and had to use a powered ethernet switch between the Pc and PLC. If you use the switch it will allow the PV to be active at the same time as you are online. The set up RSlinx with an AB I/P connection. You should be able to see the plc and the PV on the network. If not, try using the dos command window and ping the devices. You may have to reboot your PC to recognize the new network configuration. Usually with the ENBT the issue is RSLinx. I have had to uninstall completely and then reinstall RSlinx to get it to finally work. There was some issues with just upgrading. Just takes time and trying different things to get it to work.
  19. MVI56-MCM

    On the MVI56 you have to place values in certain UDT tags for your configuration as well as the reads and writes. The example does a read, write, coil read, and coil write. The device you are talking to needs to be able to accept these commands or you have to disable them. I have run into Modbus devices that won't accept an analog read but will accept and input register read. That is a different configuration. If you don't set up the Modbus read commands and the appropriate UDT's it won't work and the LED stays red. What do you mean remote. Are we talking Control net remote or RIO?
  20. Actually it is not too bad. Take the example logic and put it in your application following the instructions. Then modify the commands to meet your needs and download the cfg file through the debug port. The documentation is pretty good and they have good technical support. If you have a specific question I can try to help. I made it sound simpler than it is but it is not bad to figure out if you follow the documentation. All of the documents are online. http://www.prolinxgateways.com/content/view/full/6458
  21. Proficy ME Font support

    I have some screens where I am displaying a large amount of data. I have used an Arial Narrow True type font. This font is a selection in the software, yet I get a warning that it is not supported on the target. I can load the font in the screen and when I download the application it displays correctly. Is there any way to turn that warning off. When you get 53 warnings it is difficult to detect real problems.
  22. Versapro/Maxon project to ME

    I have been trying to convert a Hot backup system that was programmed in Versapro and used Maxon software into Proficy ME. I have followed the outlined procedures and even uploaded from the controller. And yet I continue to get Logic not equal. I have even updated the C block as GE instructs. Any thoughts.
  23. In most of the winding applications I have dealt with I used a tension sensor rather than an angle sensor of the tension arm. The reason is the as the roll gets bigger inertia plays a factor on the winding and it is barely linear. As you have found it is difficult to tune and if you have a product change where mass varies you may have to start over. I have used tension sensors or rollers that measure the tension of the product as the PV. This makes tuning and winding easier. If the winding motor is undersized like many you may have switch from speed as the CV to a torque or current mode to maintain the same tension without over winding. There are several things you can do. Set up a set of tuning parameters for different diameters based on the angle. Then you will have to tune each step individually and move the new set of parameters into the PID as the diameter increases. This will take alot of time to get it right but once done should not need to be messed with again. Good Luck
  24. RSView32 and ML1100

    You may have to use Rslinx enterprise with factory talk which was the old linx profesional. I don't think you can use Classic here. There is a difference between the drivers in SLC500 and ML1100. I just went through a ML1100 issue and a third party HMI. I had a Proface talking to a SLC500 and another Proface talking to a ML1100. The ML1100 did not work while the slc500 worked fine on AB ethernet I/P. After calls to tech support and talking with the guy who works on the ML1100 since the begining I got this explaination. The SLC505 communicates using Client Server Protocol (CSP), like the PLC-5E and Ethernet Sidecar. The Micro ML1100 uses CIPS which is a newer ethernet protocol developed for the control logix platform. The current SLC505 has both drivers available where as the ML1100 has only the newer CIPS protocol.
  25. Versapro/Maxon project to ME

    Well the reason I posted here is GE tech support is a hassle. I can give you countless reasons why I avoid them at all costs. I am following the procedure outlined, With correct versions of software and following the processes outlined. My company is a solutions provider. I have found numerous issues with PME and have several outstanding tech issues with PME. The last time I called, tech support had closed the cases. So I was forced to look for work arounds. Did not make me happy. Russ I am looking for someone who has actually done it, not some kid on a phone who is reading the procedure to me. Has anyone done this successfully?
