Generating alarms
The user configures exactly the assignment and required properties of the ports. This makes
it necessary to match the configuration and installation. If the setting in STEP 7 requires that
port 3 is not linked, this must be taken into account during installation. The power fault mask
set by STEP 7 is stored retentively and the port fault mask is reset. If you exit DataEX, the
settings in the fault mask made by STEP 7 are retained and continue to apply even without
PROFINET operation.
● Influence of the SELECT/SET button during DataEX.
Pressing the button, to set the fault mask has no effect. The port LEDs flashing indicates
to the user that there has been no change in the fault mask.
● Effect of other signaling mechanisms during DataEX
The fault mask is displayed as set by STEP 7 both in the Web interface and in CLI.
Changes are not possible. The message "Setting not possible because of PROFINET IO"
is displayed.
