Diagnostics
Diagnostics is the detection, localization, classification, display and further evaluation of errors,
faults and messages.
Diagnostics provides monitoring functions that run automatically while the plant is in operation.
This increases the availability of plants by reducing commissioning times and downtimes.
DP master
A master that behaves in conformity with IEC 61784‑1 CP 3/1 is termed a DP master.
DP slave
A slave that is operated on the PROFIBUS bus with the PROFIBUS DP protocol and that
behaves in conformity with IEC 61784-1 CP 3/1 is termed a DP slave.
DP standard
is the bus protocol of the distributed I/O system in accordance with IEC 61784‑1 CP 3/1.
DPV0
PROFIBUS DP mode between master and slave with the following properties:
● Cyclical data exchange between the central control system and slaves
● Configuration using GSD files
● Diagnostics
DPV1
Extension of DPV0:
● Non-cyclic data exchange between the central control system and slaves
● Integration in the engineering systems via EDD
● Transferable PLC software function blocks (IEC 61131-3)
● Fail-safe communication (PROFIsafe)
● Interrupts
EDD file
Standardized device descriptions (EDD - Electronic Device Description) permit the integration
of intelligent field devices from different manufacturers into different control systems. The IEC
61804-3 standard stipulates the structure of device descriptions. This standard has been
developed in cooperation with the following organizations:
● PROFIBUS International (PI)
● HART Communication Foundation (HCF)
