Hello everyone,

- TIA Version including SP / upd : TIA V14 SP1 Update 1 & WinCC Advanced V14 SP1 Update 1.

- Hardware identification : 315/2 PN/DP & TP1200 Comfort

- Doubt / problem (keyword) : GRAPH (SFC) display

- Application description (scenario) : Can't display it on the HMI.

- What type of information you are looking for : Is it possible with an S7-300 ?

I'm wondering if there is a way to display a GRAPH (Sequential Function Chart) on my Comfort HMI, knowing that my CPU is a 315-2 PN/DP. It's possible with an S7-1500 (we did it on another project), but when I try to link my S7-300 GRAPH variable to the HMI object, it says that my variable "isn't of the S7Graph type", while the exact same variable seems to be OK on the S7-1500 (see attachments 1 and 2).

By the way, the documentation says that we should link "the DB" : on the S7-1500 project, a boolean of that DB (OFF_SQ) was linked without any problem.

I'm wondering if it has something to do  with the fact that I can't access the variable of my S7-300 from the HMI with "symbolic addressing" while it's possible with that of my S7-1500 (see attachments 3 and 4).

Thank you.
