MVP 2023 Ausman Posted February 16, 2018 MVP 2023 Report Share Posted February 16, 2018 Hi Suthan, Are you saying that when you download to the controller, an alarm you have set in the existing controller program is being activated and freezes things? Normally a download puts the controller into Stop mode until finished, so an Alarm process shouldn't happen. cheers, Aus Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted February 17, 2018 MVP 2023 Report Share Posted February 17, 2018 A download will not place the PLC into stop mode unless there is a hardware or data table change (there may be a couple of other conditions that I forget at the moment). However, there is a download option called Stop-Download-Reset which will force the PLC into stop mode during download. Try that and see if it resolves your issue.

MVP 2023 Ausman Posted February 17, 2018 MVP 2023 Report Share Posted February 17, 2018 That's interesting Flex. Every time I do any sort of download, even for the most minor things, it always puts the PLC into stop mode. I always thought Reset was the optional part depending on complexity. However, I always use Download & Burn as my default. Does Download (only) simply do a change to the most minor adjustments without a stop? Always learning something new here. cheers, Aus Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted February 17, 2018 MVP 2023 Report Share Posted February 17, 2018 Burn stops the PLC. A regular download that doesn't affect the HW configuration or Data Tables does not stop the PLC. Link to comment Share on other sites More sharing options...
