PROFIBUS-DPV1 functions The NZM-XDMI-DPV1 provides various DPV1 process data
objects (data records) containing logical data which belongs
together for acyclic communication with a class 1 or a
class 2 DPV1 master. The objects can be read and/or written.
Some of these objects are only accessible for a class 2 DPV1
master as their data is available to class 1 DPV1 masters in
the cyclic input/output data.
The access of all objects occurs via the DPV1 Read and Write
service in your DP master system.
Function overview
The process data objects provided by the NZM-XDMI-DPV1
enable the functionality's listed in the following sections.
Acyclic data with class 1 and class 2 DPV1 masters
The following information can be read out:
• Status of the circuit-breaker (trip cause, load warning,
overload zone reached, phase state, fault indication),
• Parameters used in the circuit-breaker (e.g., limitation
values and delay times for overload, short circuit and fault
current),
• Local parameters of the circuit-breaker (e.g., limitation
values and delay times for overload, short circuit and fault
current),
• Diagnosis sets 1 to 10 of the circuit-breaker ( date, time,
parameters used, status of the circuit-breaker),
• Circuit-breaker identification (e.g. serial number, NZM
type, current transformer type, hardware version, software
version),
