iclim Posted February 14, 2014 Share Posted February 14, 2014 Hello, We are running into an issue with the new IDE, where after a few minutes the connection to the PPMAC is lost. I have attached a picture of the issue that we are facing including the TaskManager. It is important to note that this issue was not present on the previous version of the IDE and the only change that was made was updating to the latest IDE. We also have a development PPMAC which we use where the processor is loaded less and the issue has not been encountered. Link to comment Share on other sites More sharing options...
Omron Forums Support Posted February 14, 2014 Share Posted February 14, 2014 Sometimes, "power-saving" switches periodically turn off when there is no activity for a while. Don't use these kinds of switches. Furthermore, make sure you don't have any C programs that could be locking up the CPU for so long that background doesn't have time to send communications attempts.

iclim Posted February 18, 2014 Author Share Posted February 18, 2014 Charles, Thank you for the response. Could you please elaborate on the "power-saving" switches and how to set them. Link to comment Share on other sites More sharing options...
Omron Forums Support Posted February 19, 2014 Share Posted February 19, 2014 Hi, For example, a customer who was experiencing your issue changed to the following switch product and no longer experienced the issue: ProCurve Switch 1800-8G (J9029A) by HP Some switches periodically shut off to save power, and some others block certain communication. These sometimes cause Power PMAC to lose communication with the host. I recommend a simple, low-feature-set switch like the one listed above.

iclim Posted February 20, 2014 Author Share Posted February 20, 2014 Hello Charles, Thank you for the advice. Can you please explain why this was not an issue with the previous version of the IDE then? Link to comment Share on other sites More sharing options...
Omron Forums Support Posted February 20, 2014 Share Posted February 20, 2014 It could be a factor other than the IDE, like a change in your network configuration of which you're not aware. Extremely inefficient code that starves background (the cycle wherein communication with a host occurs) would cause this also. Look for confounding factors.
