hi all,

i am using a datalogger and one analog value is being logged. my issue is that while the analog value is always the same, i am changing digitally the sampling point of it. so i would like to be able to see it in the logger. for example i am logging a gas value from tanks. i would like to see which tank i am sampling (the digital sampling is changing every some 50 seconds so the tank name is changing too.
is this possible by scripting to change the name of the curve??
i have programmed from my plc a register to change value on each tank and i was planning to use the value to "script" and change the name of the curve(although the analog value is only one tag).
i don't know how is the name of the curve can be found (is it a function???)

any help of yours is highly appreciated.

geomariolis,

Unfortunately this can not be done using the built in legend this text is in a compiled element, however you could easily accomplish this by building your own legend popup. Instead of having the button call the trendviewer legend have it call a popup screen with a string and the value. The string will change with whatever tag you associate to it and the value as well.

Maybe this is a viable option for you.
