AUMA Industry & Marine actuators have a modular design. Motor and gearing are mounted in a common housing. The actuators are driven by an electric motor and controlled with the electronic controls PROFIBUS PBD 100. The electronic controls are included in the scope of delivery.
‘active stations’ in the PROFIBUS protocol. Slave devices such as PROFIBUS PBD 100 actuators are peripheral devices. Typical slave devices are input/output devices, valves, actuators and measuring sensors. They do not have bus access, i.e. they may only acknowledge received messages or, at the request of a master, transmit messages to that master.

General: Power supply of PBD 100 must be the same like the actuator power supply. Installation regulations for PROFIBUS-DP must be observed for the wiring.

Redundant bus connection PROFIBUS PBD 100 devices can be connected with a second (redundant) PROFIBUS cable. If the bus on channel 1 fails, e. g. through cable break, the slave automatically switches to channel 2. Connect redundant bus cable to channel 2 (optional 2. plug connector ) according to connection diagram (same as channel 1, figure B).
The parameterization is partly determined in the PROFIBUS standard, e.g. a bit for switching bus monitoring on and off (watchdog). The PROFIBUS PBD 100 control can additionally receive up to 100 bytes of ‘user parameters’, in which specific parameters can be set. The module specific parameters are divided into 50 parameters with 2 bytes each per parameter.
Operation manual Profibus PBD 100 Description of user parameters Parameter 1 “position transmitter” Default value (standard setting): 1 0: The actuator does not have a position transmitter. 1: The actuator is equipped with a potentiometer without RWG. 2: The actuator is equipped with an ESR 0-20 mA. For this position transmitter, the monitoring of signal interruption is not active.
Operation manual Profibus PBD 100 Time of initiation for the safety operation in 0.1 s. Indicates the down time of initiation of the net data transmission after which a safety operation will be started. If transmission is restored during this time no safety operation will be performed.

Operation manual Profibus PBD 100 The actuator will only run if the deviation between the nominal position and the actual position is at least equal to this value. Corresponds to the outer dead zone. This parameter must be higher than the value in parameter 12 (overrun in direction OPEN) and parameter 13 (overrun in direction CLOSE).

Operation manual Profibus PBD 100 highest value: 200 (Value for sensor with 0-20 mA or 4-20 mA output) Current at which the measuring range of input analogue 2 (option) ends. This value must be higher than the value in parameter 20 (start analogue 2 in 0.1 mA).

Operation manual Profibus PBD 100 Start of stepping distance in direction OPEN. Indication of position in per mil This value must be smaller than the value in parameter 30 (stepping end OPEN in per mil). Otherwise the parameter set will be rejected. This parameter is only effective if parameter 26 (stepping direction OPEN active) is not 0.
Important: The Profibus PBD 100 Interface PCB is a development of the Werner Riester GmbH & Co. KG. Not all functions are supported in connection with AUMA Industry & Marine actuators. In the following it is described which data bits will be used.

Operation manual Profibus PBD 100 Byte 5 to 8: reserved for extensions, must be set to 0. Description of actuator functions Operation commands for OPEN / CLOSE operation Operation commands are determined by operation command bits and the nominal value (set point) of the DP process representation input.
Operation manual Profibus PBD 100 10 Safety function The safety function permits the start of emergency operations in case of special events, e.g. when communication between the actuator and the master is interrupted. This function is set with the parameters 6 to 10. The safety function can only be set off when the watchdog function is activated in the master.
