excel values to plc (MIs)

[ctl_revotech]

Hi, I am trying to take values (more then 10 values)  from excel and write damn in my plc (a v1040) by using unidde. My problem is that, sometimes and happenning randomly, some of the values are not write in my plc. I can confirm they are not write in my plc because i am looking at my hmi with the appropriate MI link. So i was wondering if this ever happened to somenone before me. Also, my goal is to take data from excel (or another software) and download / write them in my plc, could i use another software or way to get that done. 

 

Thanks
