  1. Wincc flexible 2008 sp4 Asia migration

    Hmmmm.... I tried to open the project in WinCC Flexible 2008 but I can't, probably because I have SP3, not SP4. I then tried a migration to Portal v13 but it won't let me, saying that only projects saved in SP2, SP3, or SP5 can be migrated. Is there any way you can save your WinCC project in version SP3? Go to Project, then select "Save as version".
  2. Communication problem : PLC, HMI and switch

    Is the HP switch managed or unmanaged? If it's managed, I'll defer to others. If it's unmanaged... Can you ping the PV+ and PLC from your laptop?
  3. Wincc flexible 2008 sp4 Asia migration

    Hmmmm..... It may be something specific to the Asia version, but we were able to migrate an SP3 project to Portal with no issues. We also have v13 and v14 both installed, so that may be the difference. Can you share your WinCC project? I'll give it a try here. I don't have the Asia version of the software, so I can't guarantee it won't break something unexpectedly.
  4. Defaulting Memory Card to fix connection issue

    If the RS232/USB adapter is connected to the VM using the "removable devices" menu, go to Device Manager and double-check which COM port number it was assigned. It may not be the same port number it got last time, especially if it's plugged into a different physical USB port. But, from what you said, it's configured for an ASCII protocol that RSLinx can't use (if your research is right, I haven't confirmed that). Are you still using that scale? If so, you're not going to get very far with setting the COMMS to default. Once you download the program back to the PLC to get online, the port will revert and you'll be dumped offline. Since you're using the COM port for a scale, and DH+ to an HMI, you won't be able to use a 5/05 since the 5/05 doesn't have a DH+ port. Your best bet right now is probably to connect to it via DH+, which won't be cheap. Actually, a better bet is to replace the 5/04 with a 5/05 and the HMI with one that supports Ethernet. That may not be in your budget, though. We've had very bad results from the AB U2DHP modules. They are very expensive and just stop working without having been "abused". For systems where we must use DH+, we have a couple of Prosoft Ethernet to DH+ modules (AN-X2-AB-DHRIO). They're pricey, and need an external power supply, but they've been flawless. We used to have a ControlLogix chassis on our computer cart with a 1756-ENBT module in one slot and a 1756-DHRIO in another. That worked well too but was a little cumbersome and would only be cost effective if you had those components lying around unused. Our standby for aftermarket cables has been these guys: https://www.plccable.com/allen-bradley-1784-u2dhp-alternative-usb-to-data-highway-plus-dh-anc-120e/ We haven't tried their DH+/USB system since we already have the Prosoft system working, but it is cheaper than the AB version, at least for us with our AB pricing. The SLC 5/04 has a round mini-DIN port and the 3-pin phoenix connector on the front. Both are the same DH+ port, so you can get your gateway device connected at the same time as the HMI.  
  5. Defaulting Memory Card to fix connection issue

    Also, are you using a virtual machine? If so, try connecting the USB-Serial adapter directly to the VM instead of the host. We've had trouble with the physical COM port of the host not translating predictably to the VM.
  6. Micrologix 1200R Communication port & cable

    You can also get a "standard" programming cable for the MicroLogix with their custom mini-DIN type connector on one end an a 9-pin d-shell connector on the other. I think that's the 1761-CBL-PM02 cable. Then, get a programming port with the 9-pin d-shell connector. You can then use just a standard serial cable to connect to your PC. Edited to add: The AB cable tends to be expensive, but here's an aftermarket one: https://www.plccable.com/allen-bradley-micrologix-cable-serial-1761-cbl-pm02-90-deg-end/ We've used their cables before with great results.
  7. plc5 conversion

    Can you post your RSP file?
  8. I've also seen issues with doors when the enclosure isn't level. make sure all 4 corners are on a level, flat surface. If it's sitting on a pallet, move it to a flat, level floor and try again.
  9. Controllogix 1756-OF8 Wiring help

    Looking at the wiring diagram in the user manual, the 1756-OF8 doesn't require an external power supply connection. The analog signals are generated within the module using power it gets from the backplane. See page 144 of this manual: https://literature.rockwellautomation.com/idc/groups/literature/documents/um/1756-um009_-en-p.pdf  
  10. this is for the HMI

    HMI manual.pdf

  11. Hi, Joe E,

    please find attached  some part of the documents 

    electrical diagrams.pdf

  12. Have you gotten anything back from the machine builder? You really need the *.apa file for the HMI for this project but you should try to get their copy of the *.RSS file too so you get the documentation for future use.
  13. As mentioned above, someone with time on their hands will need to trace out the code and figure it out a line at a time. I can't do it for you on company time or on the company laptop and I don't have the software to do it on my own.
  14. I hate to say it, but without the source files you have your work cut out for you. Do you have pictures of what the screens were and what they displayed?   The best possible outcome is that whoever built the machine is still around and you can get the source files from them.
