Individual solutions for individual challenges There is no such thing as a standard actuator, even if most processes appear to be standardised. Because all industrial processes have their own specific particularities. Therefore, AUMA always produces individually cus-tomised solutions and only manufactures upon receipt of order. The multitude of existing valve types, Distributed Control Systems, application conditions and standards call for flexible actuator and controls solutions. Always tailor-made to suit the appropriate application whilst respecting customer demands. Modular design...

A fieldbus is an industrial communication system, Connecting a variety of field devices such as trans-ducers (sensors), MOVs and actuators (drives) with a control system. Fieldbus technology was developed in the 1980s to replace the parallel wiring of binary signals, which was common at that time, as well as analogue sigͭnal transmission by digital transmission technology. Today, many different fieldbus systems with different characteris-tics have become established on the market, e.g. Profibus, Interbus, ControlNet, or CAN. Since 1999, fieldbus systems worldwide have been standardised...

The fieldbus replaces the parallel trunk groups by a single bus cable and connects all levels, from the field to the process control level. Whatever the automation device, e.g. programmable logic controls (PLC) from different manufacturers or computer-based controls, the fieldbus transmission medium links all components. The devices can be located anywhere in the field. Fieldbus therefore provides a powerful communication network for state-of-the-art modernisation concepts. Digital transmission Only digital information is transmitted in fieldbus systems. Analogue setpoints or measured...

Fieldbus systems have many advantages compared to parallel wiring Reduced wiring saves time during planning and installation. ■ Cables, marshalling rack and dimensions of the control cabinet will be reduced. ■ Reducing the components reduces the documentation at the same time. ■ More information can be transferred using fewer wires. ■ Self-diagnosis of the devices via fieldbus reduces downtimes and maintenance times (asset manageͭment). ■ Digitalisation of analogue values improves the protection against disturbance of signals. ■ Digitally collected measurement values and digitally generated...

Fieldbus cables/installation Cable types Data transmission via fieldbus cannot be implemented on any cable. Cable types are specified for each fieldbus system. Due to the low data transmission rate, the requirements for Foundation Fieldbus are comparatively low; DeviceNet requires more complex cables as the bus specification requires a separate supply voltage within the same cable. Installation Data transmission on fieldbus systems are performed with low signal levels, e.g. +/- 5 V. The installation has to be performed thoroughly to ensure fault-free data transmission. This applies to...

The further development of fieldbus protocols and the increasingly intelligent field devices provide the framework for a variety of additional bus-supported functionalities. This includes simplified device integration, remote pro-gramming and diagnosis of all connected devices by the bus itself via a central computer. Commissioning Contrary to conventional wiring where different signals do not interfere with each other and do not require a chronological order, fieldbus devices have to adhere to strict organisation principles to ensure fault-free communication via the common data...

During opration In addition to the central dlimitation of communication parameters, field device configuration can be influenced online: the process behaviour, e.g. of an actuator, can be changed from the control room. The operating behaviour of the field devices can be optimised during operation without gaining access to the device. At the same time, diagnostic information is available, helping to optimise the device parameters with regards to an extended lifetime or enabling more efficient maintenance. The remote parameter setting is only possible if the fieldbus supports the...
