Hello PeterRad, the SFC has got two modes:
If you change the mode from MANUAL (standard) to AUTO mode you can't control the SFC from WinCC. All buttons will be all buttons are grayed out. You can change the mode of the SFC in the external view with the inputs AUT and ENAUT. I don't know another way to forbid the step control mode. With regards |

Changing your SFC to AUTO will do this, but it is not always optimal to run your SFC in AUTO if t is a user driven sequence. There is another way: You can change the permission levels for these buttons in the OS project. So your normal users can't change the modes, but admins/engineer/supervisor can according to your security model. See the attached screenshot. Note you can change this globally for all SFC or customized for each instance. |
If my post helped you, please rate. Thanks. |
