Hey all, Had a little glitch yesterday while trying to program our DL06 through Com1 using a laptop with DirectSoft32. We tested the cable and it was ok. The PLC Com 1 was ok because it was able to communicate with the HMI in run mode. Still the error showed up. We narrowed down the problem to the serial com port on the laptop instead. So what we did was to remove the serial com port hardware profile from System/Device Manager and reinstall it. Now, everything works as before. Strange if you ask me but I hope this trick can help someone out there. Thanks for reading.

There are several applications that "hijack " the com port and refuse to "share ". PDA device software, digital camera software, and a few industrial programming packages are notorius for this. Some of these applications hijack the port at a very low level and the only way to "remove " them is to do what you did, uninstall and reinstall. If you are using a "Pro " version of a Windows OS, you can sometimes find these applications in the "Services " listing (Start -> Programs -> Administrative tools -> Services or Control Panel -> Administrative tools -> Services) and disable them.
