how to run script continue in wincc flexible run time on PC

MM1234

Hello guys, I am not sure if this has been said here or not, however, if I understand it right, I got myself into situation like this while trying out one fun project too. The issue for me was, that slowest aquisition cycle of a variable in wincc flexible is 1 second and I used PLC, where you can use aquisition cycle 100 miliseconds.

Anyway, the way I do the thing is using a comparison of previous value and current value of a PLC variable and in PLC have simply one network that increases integer in that variable by 1 every cycle and if it's 32000 it resets to 0.

I guess you can make such sort of thing in the wincc flexible alone, just make a variable which will on change value call a script and in that script do what you need to do continuously and then increase value of that variable by 1 (and eventualy reset for the overflow back to 0). The only issue I can think of is starting the cycle at the very first time, you just need to do some sort of an "onload" trigger.

Hello!

it can be a problem if you have 100 tags from the plc, and the acquisition time is 100ms in every tags? The profinet can handle with this amount of data?

Sorry for my english.

Kind regards,

Lehel
