Settings/programming the Profibus DP interface
Automatic baud rate recognition
Baud rate setting
Setting of the Profibus DP address is performed via address switches, alternatively also via parameters
Setting the Profibus DP interface
For an optimum adaptation to the process control system, the process representation can be configured
as desired.
Configurable process representation
via GSD file
General Profibus DP interface data
Profibus DP according to IEC 61158 and IEC 61784-1
Communication protocol
●
Line (fieldbus) structure
●
When using repeaters, tree structures can also be implemented.
●
Coupling and uncoupling of devices during operation without affecting other devices is possible.
Network topology
Twisted, screened copper cable according to IEC 61158
Transmission medium
EIA-485 (RS485)
Fieldbus interface
●
Baud rate and maximum cable length (segment length) without repeater:
-
between 9.6 and 93.75 kbit/s: 1,200 m
-
for 187.5 kbit/s: 1,000 m
-
for 500 kbit/s: 400 m
-
for 1,500 kbit/s: 200 m
●
Baud rate and possible cable length with repeater (total network cable length):
-
between 9.6 and 93.75 kbit/s: approx. 10 km
-
for 187.5 kbit/s: approx. 10 km
-
for 500 kbit/s: approx. 4 km
-
for 1,500 kbit/s: approx. 2 km
Transmission rate/cable length
●
DP master class 1, e.g. central controllers such as PLC, PC, ...
●
DP master class 2, e.g. programming/configuration tools
●
DP slave, e.g. devices with digital and/or analogue inputs/outputs such as actuators, sensors
Device types
32 devices without repeater, with repeater expandable to 126
Number of devices
●
Token-passing between masters and polling for slaves
●
Mono-master or multi-master systems are possible
Fieldbus access
Cyclic data exchange, sync mode, freeze mode, fail safe mode
Supported fieldbus functions
0x0C77: Standard applications with Profibus DP-V0 and DP-V1
Profibus DP ident no.
Commands and signals of the Profibus DP interface
OPEN, STOP, CLOSE, position setpoint, RESET, EMERGENCY operation command
Process representation output
(command signals)
●
End positions OPEN, CLOSED
●
Actual position value
●
Selector switch in position LOCAL/REMOTE
●
Torque switches OPEN, CLOSED
●
Limit switches OPEN, CLOSED
Process representation input
(feedback signals)
●
Motor protection tripped
●
Torque switch tripped in mid-travel
Process representation input
(fault signals)
The behaviour of the actuator is programmable:
●
Stop in current position
●
Travel to end position OPEN or CLOSED
●
Travel to any intermediate position
●
Execute last received operation command
