PROFIBUS DP
PROFIBUS DP is an open bus system in accordance with the standard
IEC 61784-1:2002 Ed1 CP 3/1 with the transmission protocol "DP" (distributed peripherals or
I/Os). The "DP" is a high-speed protocol for cyclic data exchange between the controller and
the distributed I/O systems.
Physically, PROFIBUS DP is an electrical network based on a shielded twisted-pair cable.
PROFIBUS DP has the following properties:
● Hierarchical master-slave principle
● Transfer rate up to max. 12 MBit/s
Functionality of the 3RW5 communication module
● DPV0 slave
● DPV1 slave
● S7V1 slave
● Operation in redundant controllers behind a Y-Link
● Diagnostic interrupt
● Removal and insertion interrupt (3RW5 HMI High Feature)
