Hello everyone,
I have the goal to make a conenxion between my plcnext 2152 and Ignition.
I succesfully creat the connexion and i see data in real time.
![]()

however, when i try to make a graphical it wont change or display old value
Both of my variable are history with an historian i creat
![]()
Is anyone try a equivalent project ? am I making something incorrect ?
Thanks you for the time you accord me
