Gateway Configuration
You can configure the gateway only via the PROFINET IO engineering station. In order to view
the parameters in read-only status, use the web server or the gateway device type manager.
4.8
Gateway Device Parameters (DAP Submodules)
4.9
PROFIBUS PA Master Parameters (FAP Submodules)
Almost all PROFIBUS PA master parameters are set to default values and cannot be changed.
Only the values
“
maximum retry limit
”
and
“
watchdog time
”
can be changed. We recommend to
configure no less than 4 retries when operating the PROFIBUS PA installation, provided that
any of the following operation conditions apply:
■
High level of environmental impact
■
Vibration or shock
■
Field devices connecting or disconnecting regularly during operational conditions
The PA master address for each segment is fixed to "1".

Start-Up Behavior
After powering the Power Hub, the gateway starts to poll for connected PROFIBUS PA devices
in order to generate a live list. If a connection to a PROFINET IO controller and the
PROFIBUS PA devices are configured in the PROFINET IO system, the gateway starts the
IO cycle on the PROFIBUS PA segments.
