When adding the AS-i/PROFIBUS-Gateway VBG-PB-K20-DMD 576 A1745 using

Configuring AS-i/PROFIBUS-Gateway in-/output
If the AS-i/PROFIBUS-Gateway is added to the PROFIBUS using drag and drop,
the Step7 hardware configuration shows the following graphic.
At this point the desired PROFIBUS communication module should be parameter-
rised. This is done in the following steps:
1. Select the AS-i/PROFIBUS-Gateway by clicking on the Slave icon. In the lower
edge of the screen a table is shown which contains lines beginning with Slot 0.
2. Select the desired communication module "Flags + Fault Detector" from the
hardware catalog. These flags use the individual bits to signal the operating sta-
tus of the AS-i/PROFIBUS Gateway and should be processed in the application
program.
