hello experts, I am having similar issue where Hmi tags (I/o fields ) on my screen would show 0 instead of actual values upon start up (warm start with mains power cycled) These hmi tags are linked to entries in a data block of a fb. This function block has all the boxes checked next to its all static variables. So just after start up I monitored the data block and all actual values remained the same as they were before shutdown, it`s only the hmi io fields all showing zero. I tried playing around with the continuous and cyclic acquisition, except the on demand, which I could not figure out how to use. The only thing that actually worked was having the data block entries copied to default tag table tags, and those ones are always updated in my hmi io fields, even after a warm start up. However having to copy and duplicate all these variables are a bit of a pain and would like to find out if there is a better way please. I am using Tia vs 15 professional and s7 1200 cpu 1214 dc/dc/rly and basic hmi panel. Tried looking at help pages in Tia but the explanation of updating tags on demand was a bit above me unfortunately. Thanks ------------------------------------------------------------------------------------------ |
