Call FB in S7graph

Hello all experts.

i'm making a software with S7-graph and i have some question that need your help.

1- i called some FB inside s7graph FB, and i need to see the situation of In/OUT of called FB in monitor mode, but i didnt see. i used Vat table to see the In/OUT condition.

2- i need to convert (Not) some In/out  of called fb inside the s7gragh program, if you see the attached photo , how can i convert "Drive_Ready"input?

3-how can i use SFC17 & SFC18??

thank you

Hello Shahab;

My experience with S7-Graph has been with Simatic Manager and S7-300 PLCs, so I can onlly provide what I remember, and point you to the S7-Graph v5.3 manual:

https://support.industry.siemens.com/cs/ww/en/view/1137630

One of the standard actions in S7-Graph is "Call", which will open a specified FC, FB, SFC or SFB. FBs and SFBs must have a generated IDB, which you can open by double-clicking on the FB Call.

To negate a signal in S7-Graph, if i remember well, must e done in a FBD network, not LAD. It is easy enough to enter a FBD network, look it up in the manual.

Hope this helps,

 Hello Daniel,

thank you so much for your response.

it is possible to invert a signal in STL too when i insert an action and write a command like attached picture according to the manual, but please see the second page, i want to invert one of the input of inside FB, i didnt find solution, please check again.

Best regards.
