Here too, the project engineer does not stipulate the port assignment for the installation
engineer. The alarm response is adapted automatically. When the device enters DataEX
mode, the network component reads the actual states of the connections and records
them as the desired state for this operating mode.
– Effect of the button during DataEX
Button actuation is ignored. The configured desired response is retained even when
the device exits data transfer mode. An LED flashes briefly to indicate to the user that
button actuation is ignored.
– Effect of other WEB signaling mechanisms
When the device switches to data transfer mode, the Web signaling mechanisms are
adapted to the PNIO setting. The fault mask is disabled in WEB. The message
"Setting not possible because of PNIO" is displayed.
