Technical data
Communication protocol
PROFIBUS-DP according to EN 50 170, DIN 19 245
Network topology
Linear (BUS) structure. With repeaters tree structures can also be realised. Coupling and
uncoupling of stations during operation without affecting other stations is possible.
Transmission medium
Twisted, screened copper cable according to EN 50 170
Interface
EIA-485 (RS485)

Station types
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 binary and/or analogue in-/outputs such as actuators, sensors
Number of stations
32 stations without repeater, with repeater expandable up to 126.
Bus access
Token-passing between the masters and polling for slaves.
Mono-master or multi-master systems are possible.

-
manual operation by handwheel or local controls
-
communication channel A or B (redundant channel) active
Process representation input
(fault messages)
-
motor protection tripped
-
voltage supply of PROFIBUS-DP board outside of permissible range
-
loss of an analogue input signal
3-position controller (option)
Max. error and max. dead time programmable via BUS.
Electronic timer (option)
Start and end of stepping mode as well as ON / OFF time can be programmed via the BUS.
Behaviour in case of
communication failure or CLEAR
state of the master
The behaviour of the actuator is pro-
grammable: - stop in current position
- move to end position OPEN or CLOSED
- move to any intermediate position
Cable redundancy (option)
As an option, a second transmission cable can be connected
