“Warning” marks activities or procedures which, if not carried out correctly, can affect the safety of persons or material. Short description AUMA 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 elec- tronic controls AUMA MATIC Modbus.
Master devices control the data traffic on the Bus. A master is allowed to send messages without an external request. Slave devices such as AUMA Modbus actuators are peripheral devices. Typical slave devices are input/ output devices, valves, actuators, and measuring transmitters.
Bus access Master-slave technique. Mono-master system. Master and slave devices: max. 127 devices at one bus (the AUMA MATIC supports slave addresses from 1 to 127), without repeater max. 32 devices. Communication Master-slave data exchange via query-response cycle (Polling procedure).

In case the wiring diagram is not available, it can be obtained from Figure B-2: Parking frame (accessory) AUMA (state commission no., refer to name plate) or downloaded directly from the Internet (www.auma.com). A special parking frame (figure B-2) for protection against touching the bare contacts and against environmental influences, in case the electrical connection has been removed, is available.
15 or page 17. For version with FO (fibre optics), refer to separate operation instructions “AUMA MATIC AM 01.1/ AM 02.1 FO connection”. Connect bus cable. Refer to figures C-1 and C-4. The termination resistors for channel 1 and channel 2 are switched in via switches (S1) and (S2).
For the connection of remote position transmitters (potentiometer, RWG) screened cables must be used. AUMA MATIC on wall bracket The AUMA MATIC can also be mounted separately from the actuator on a wall bracket. Figure C-5: AM on wall bracket For the connection of actuator and AUMA MATIC on wall bracket, use suit- able flexible and screened connecting cables.

Additionally, the communication cannot be carried out on both channels simultaneously. If the redundancy is activated (see parameter 4 “Redundancy”, page 34), the AUMA MATIC transmits its data using both channels but receives the data only using the active channel. This cable redundancy may only be applied after previous integration test using the desired process control system! For versions with AUMA plug/ socket connector (subclause 7.2):...
