Posted 24 Feb 2017 Hi guys, Yesterday I posted a question about how to create a trigger for a log. Now I have the next problem. I created my log, loaded the Logging firmware on the GOT but the CVS file is not generated. Can someone tell me what i'm doing wrong? I am attaching all the settings and the PLC part of the program. I want the values of ZR1200 ZR1204 and ZR1205 every time they change. They are recipe values. I tried also putting a button to create the log file on the HMI. Did not work.

Posted 24 Feb 2017 I found the problem if you are interested. I used a PLS command for the memory bit trigger. It was too fast. Created a delay of 1 second and it works. 1 person likes this Share this post Link to post Share on other sites
Posted 16 Jun 2017 @Andrei. I see you had rising edge Logging Bit command input executing the PLS instruction for the Log trigger. I always find this combination is tricky on long scan programs. Usually here you need one of the other. Share this post Link to post Share on other sites
Posted 17 Jun 2017 Or even better, handshake with the HMI: 1. SET your logging trigger 2. Map the 'Logging Notification Device' to an M contact 3. When this M contact turns on or any relevant alarms occur, RESET the logging trigger This is much more robust than using a timer delay. Share this post Link to post Share on other sites
