8.8.3.4 CFU PA: Displaying DPV0 alarms on CFU PA LEDs
The CFU PA can signal DPV0 alarms via the following LEDs:
● LED of the fieldbus connections
● "ERR" LED
If the display is required, you must activate the parameter in HW Config.
You can find information on this in section "CFU PA: Assigning parameters to the PROFIBUS
PA Master (parameter overview - FB M) (Page 97)".
You can find information on the LED displays in section "Diagnostics via LED displays
(Page 107)".
8.8.3.5 CFU PA: Comparing TAGs
The CFU PA can automatically compare the name of the field device (TAG) with HW Config.
● If the display of inconsistencies is required, you must activate the parameter in HW Config.
You can find information on this in section "CFU PA: Assigning parameters to the
PROFIBUS PA Master (parameter overview - FB M) (Page 97)".
● You can find information on the LED displays in section "Diagnostics via LED displays
(Page 107)".
8.8.3.6 CFU PA: Service interface
You can configure one fieldbus connection of the CFU PA as a service port for the field devices
of this CFU PA (e.g. for calibrating the field devices in a specified environment).
● Settings on the engineering system or on the field device are not required.
● If the service port is enabled, you can calibrate field devices connected to the service port.
The field device behaves the same when connected to the service port as when connected
to the original fieldbus connection and continues supplying process values to the previous
address.
