Dovi Posted January 4, 2017 Share Posted January 4, 2017 Hi, I built a project on DF using MBTCP for comm with PLC. In general, I read recipes for 5 different tanks in parallel from an Excel file into channels going to the PLC. When I choose recipe & tank to which the recipe in intended (1.jpg) - a sequence is generated to read other data from the file to selected tank's channels. The script is running fine and the data is being read but there are a lot of times some "holes" and data missing because of Comm.problems (2.jpg) so I need to run the script multiple times. It's not happening always but it's bothering. I entered delays in the sequence but it didn't help (3.jpg & 4.jpg). I'm connected to the PLC directly and not by a switch. What should I check more ?

AzeoTech Posted January 9, 2017 Share Posted January 9, 2017 Any way you could send me a section of the comm monitor at the time of loss? Make sure you have "Display all chars as ASCII Codes" and "Display time of Rx/Tx" checked. Are you on RS485 multidrop? Link to comment Share on other sites More sharing options...
Dovi Posted January 10, 2017 Author Share Posted January 10, 2017 When I just start the comm monitor with my device it starts to get wild & the project is stuck - I get this (11.jpg) alarm every couple of seconds. I'm not on RS485 multidrop. Link to comment Share on other sites More sharing options...
AzeoTech Posted January 11, 2017 Share Posted January 11, 2017 That error just means DAQFactory had enough timeouts that it couldn't keep up with your desired timing interval and had to reset the timing clock. Its a side-effect of your main problem. Simplify your system as much as possible, for example, read just one channel and see what happens. Link to comment Share on other sites More sharing options...
