DP standard
DP standard is the bus protocol of the ET 200 distributed I/O system in accordance with the
standard IEC 61784-1:2002 Ed1 CP 3/1.
DPV0
"DPV0" mode designates a mode for communication between devices on the PROFIBUS.
The mode includes the basic functions of the PROFIBUS DP communication protocol
• Cyclic data exchange between control system and devices
• Configuration via GSD files
• Diagnostics
DPV1
"DPV1" mode is a further development of the original PROFIBUS standard IEC 61784-1:2002 Ed1
CP 3/1.
DPV1 designates a mode for communication between devices on the PROFIBUS.
The mode extends the functions of the PROFIBUS DP communication protocol compared to
"DPV0" mode. The changes are specified in the IEC 61158 standard:
• Acyclic data exchange between control system and devices
• Integration into engineering systems via EDD or FDT / DTM
• Transferable PLC software function blocks (IEC 61131‑3)
• Fail‑safe communication (PROFIsafe)
• Interrupts (hardware interrupt, status interrupt, update interrupt, vendor-specific interrupt,
diagnostic interrupt, plug interrupt, pull interrupt)
Electronic module
Modules of distributed I/O with signal processing:
• For acquiring the signals from sensors
• For outputting signals to actuators
• For special signal processing (e.g. counting, measuring frequency ...)
Equipotential bonding
Electrical connection (equipotential bonding conductor) that keeps electrical equipment and
extraneous conductive objects at the same or roughly identical potential in order to prevent
disturbing or dangerous voltages between these objects.
