  1. Just fixed a vexing problem that caused Windows 10 File Explorer to crash without warning any time I tried to display a folder containing a .vlp file. In fact, any Windows application I used to try accessing a .vlp-containing folder would crash without warning. Various browsers, MS Outlook, and TreeSize Free were several that I tried. In addition, the Windows 10 Settings > "Choose default apps by file type" utility would also crash any time I tried to launch it! And no, I did not try running VisiLogic. Probably should have, but didn't. Interestingly, DOS command prompt and DOS dz.exe utility had no problems whatsoever with viewing, creating, and deleting .vlp files. I've had VisiLogic 9.8.31 installed for quite a while without problems, and this appeared out of nowhere sometime within the last week or two. Maybe some recent update to Win 10 triggered the problem, but I just wanted to document it in case anyone else experienced this issue. The steps I took -- and I'm not sure which solved the problem -- were as follows: 1) Deleted all .vlp file association info from the registry. 2) Set UAC to minimum and uninstalled VisiLogic 9.8.31. Did not delete extra files as some others have done after uninstalling VisiLogic. 3) Installed latest version of VisiLogic: 9.8.65. 4) Set UAC back to safe setting. 5) Rebooted. All better now. Folders containing .vlp files are accessible and the Settings file association tool works fine. I am currently running Windows version 10.0.15063.413, although I'm not sure what it was running when I was having problems because Windows pushed two rounds of updates after I installed the newer version of VisiLogic and rebooted.
  2. I'm trying to get UniOPC to communicate with Inductive Automation's Ignition product, but cannot get Ignition to connect to the UniOPC server. It recognizes the server (both application on same Win 10 PC), but will not connect. Has anyone else done this with good results? If so, any hints about any special configuration settings? Note that UniOPC communicates just fine with OPC Expert, which is an OPC client application used mainly for troubleshooting. Thanks in advance!
  3. Serhat, Since Siemens addressing is a bit different -- pun intended -- than VisiLogic addressing, you need to do things a bit differently to emulate the bit-level access. Here is a first-try draft that should be pretty close to a literal translation of your S7 code. This may need tweaking but should give you a start:
  4. Resetting DCOM Identity

    Let me clarify and apologize for any confusion. The UniOPC DCOM identity setting actually changes when I launch, run, or stop UniOPC, so I really question whether it can be an IT problem. So, is this not normal behavior on a typical UniOPC installation?
  5. Resetting DCOM Identity

    I am experiencing this same behavior with UniOPC 2.0.14 on Windows 10. Does anyone know of a solution? Thanks!
  6. I encountered a very similar problem where a popup window asked me to run the AutoCAD 2016 installer every time I launched VisiLogic. The software worked fine otherwise. Running the VisiLogic installation with Repair option did not fix this popup oddity. Solution: Uninstalled AutoCAD since I did not need it on this PC anyway. May not be an option for everyone, but it worked for me.
  7. Ah, I see. And even if I could have found it, I would not be able to read it since it's in Chinese, so it's just as well. Thanks!
  8. That's great info! Thank you so much.
  9. Where might I find detailed descriptions of each MI in the 32-MI PID Autotune vector for the Vision series, V130 in particular? I'm sure this is documented, but I'm having a bugger of a time finding it. Thanks!
  10. Okay, I think I've found the problem. Opcenum.exe is installed in the "C:\Windows\SysWOW64" directory and the path is not known to Win 7 when I try to run opcenum /regserver, so I have to instead include the path in the run instruction: C:\Windows\SysWOW64\opcenum /regserver. I had also un-installed and re-installed with UAC set to minimum (turned off, basically), but nothing changed. Here is the answer to one of my questions, straight from the UniOPCHelp: UniOPCServer installationAlthough OPC servers can be installed by any user having administrator privileges, we recommend that installation be done under local administrator log-on. In compliance with the OPC DA v2.x specifications, it is recommended to use the OPCEnum application, which enables OPC clients to browse the available OPC servers. This application is installed together with UniOPC Server. So, clearly opcenum.exe is supposed to be installed by UniOPC. It looks like it was just installed in a location unknown to Win 7. Elaborating on my symptoms... From the UniOPC Help, I run into what may or may not be a problem here: "11. Click the Default Protocols tab. The default protocols should appear as shown in the figure below; if they do not, update them." Help shows two entries at this point: "Connection-oriented TCP/IP" and "Connection-oriented SPX". I have the first entry, but not the SPX protocol, so no, my default protocols do not match what the help information says they should match. Is this a concern? I also have problems at this step from Help: Register OpcEnum: "Start> Run>OPCENUM /regserver". My 64-bit Win 7 PC says "Windows cannot find 'opcenum...'. The failure in this step of the procedure caused failure in the next step, too, and OPCenum did not appear in the list of DCOM Component Services. After running opcenum /regserver with full path specified, OPCenum DOES appear in the DCOM list. Not completely up and running yet, but got past the first hurdles...
  11. Just installed UniOPC on my Win 7 PC and got to a point in the setup instructions that did not work as described. Then I discovered that opcenum.exe is not on my Win7 PC where expected (Windows\system32\). It looks like this is an OPC Foundation redistributable file that probably should have been installed with UniOPC. Or am I wrong? Also, I cannot find this file for download, not even at the OPC Foundation website. Incidentally, I did not disable UAC when installing UniOPC, if that makes a difference. Any help is appreciated.
  12. I am looking for manufacturer and part number information for the pluggable, green terminal blocks on the V130 units. Any help out there? Thanks, Joel
