| Fieldbus Diagnostics and Asset Management |

The Diagnostic Power Conditioner detects long-term faults in the Foundation Fieldbus segments and thus supports plantwide asset management |
Whilst many plant operators today already record the data from control system components, field devices or motors in an asset management system, physical layer components, i.e. the infrastructure for connecting field devices and control systems, are mostly only documented. Turck offers a solution for this with a growing range of products that can be managed with FDT/DTM in an asset management system. The latest member of this range is the Diagnostic Power Conditioner System which can monitor Foundation Fieldbus networks for long periods, thus creating entirely new possibilities for plantwide asset management.
Nowadays, the typical three layer structure of the automation pyramid is implemented in virtually all process engineering plants. The lower layer or field level contains the physical interfaces to the processes. The process level is the middle layer. This is where the process control system operates for controlling and visualising the processes involved. The top layer or management level is where the ERP systems manage plant data and present it.
Whilst the management level is normally connected to the process level via Ethernet, more and more users are implementing the fieldbus for the connection between the process level and the field level. This enables both installation costs and longterm operating costs to be considerably reduced. A fieldbus architecture supports the decentralised structure of a modern processing plant and expands the structure of a decentralised process control system down to the sensor and the control elements.
In addition to these installation benefits, fieldbus solutions also offer benefits during the ongoing operation of a plant since additional information can be transferred as well as process values and manipulated variables...
