Setting/programming the Profibus DP interface
Automatic baud rate recognition
Baud rate setting
Profibus DP address is set via parameters (commissioning and diagnostic tools or AUMA Assistant App)
Setting the Profibus DP interface
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. parts programming/configuration tools
●
DP slave, e.g. devices with digital and/or analogue inputs/outputs such as actuators, sensors
Device type
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.
Bus access
Cyclic data exchange, sync mode, freeze mode, fail safe mode
Supported fieldbus functions
0x1146. 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, CLOSE
●
Limit switches OPEN, CLOSE
Process representation input
(feedback signals)
●
Motor protection tripped
●
Torque switch tripped in mid-travel
Process representation input
(fault signal)
The behaviour of the actuator is programmable:
●
Stop in current position
●
Execute operation to end positions OPEN and CLOSED
●
Travel to any intermediate position
●
Execute last received operation command
Behaviour on loss of communication
