segal Posted October 6, 2018 Report Share Posted October 6, 2018 Hi! This weekend something was happening with a well-functioning plc, what do you think was the trigger? These pictures were sent from him, before restarting, and restarting. You may have been disconnected through the modbus connection? Quote Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted October 6, 2018 MVP 2023 Report Share Posted October 6, 2018 The application software was lost. Is the battery good? Check the battery and the power supply, then reload the application from VisiLogic or an SD card. To prevent this, do "Download All & Burn" when downloading the application.

MVP 2023 Ausman Posted November 5, 2018 MVP 2023 Report Share Posted November 5, 2018 Hi Rel, your english is better than my french! Please clarify.....is there a "no application" message like in the above screenshots, or is the application there but it has lost the previous parameters? 7 hours ago, ReIYeL18 said: it don't remember my last paramaters when I restart it These are 2 different problems. cheers, Aus Quote Link to comment Share on other sites More sharing options...
MVP 2023 kratmel Posted November 5, 2018 MVP 2023 Report Share Posted November 5, 2018 Please test "Battery status bit" SB8 in visilogic. If it is 1- battery not OK or it not connected to properly (bended contact). Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted November 6, 2018 MVP 2023 Report Share Posted November 6, 2018 This can be caused by noise gremlins getting into the CPU via the I/O module. Do you have any VFDs in the system? Joe T. Quote Link to comment Share on other sites More sharing options...
segal Posted November 28, 2018 Author Report Share Posted November 28, 2018 Hi! I have another problemHiba 1.pdf. I did not want to open a new topic. I do not know why, but the sum of two positive numbers will be a negative result. Why is this why? Where do I find the fault? Quote Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted November 28, 2018 MVP 2023 Report Share Posted November 28, 2018 How big are the numbers? Are you overflowing the register? If you're using MIs, try using MLs. Quote Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted November 28, 2018 MVP 2023 Report Share Posted November 28, 2018 Oh, I missed your pdf. Yes, you're overflowing the 16-bit register. The largest value an MI can hold is 32,767. Use MLs. Quote Link to comment Share on other sites More sharing options...
