1.5Typical applications in conveyor technology

Plant topology

Typically, the control is located in a central control room. The scanning points are located at a greater distance along the assembly line or conveyor line. The data carriers are often attached to a conveyor such as a skid, a industrial pallet or a work piece carrier in order to allow for a closed cycle of the data carriers. The data carriers pass through all stations of the plant and are of-ten subject to special external environmental influences such as tempera-ture, pressure, dirt, chemically aggressive substances and dampness.

Mounting and commissioning

Suitable mounting points for the data carriers must be determined on the conveyors manufacturer. It must be ensured that the surrounding metal does not have any negative effects. The read/write heads and the control units are mount-ed along the path and electrically connected. Using the IDENT Control sys-tem, the function of the components can already be controlled on site by means of paramterisation and command input, ensuring a correct transfer and acceptance. Often the PLC with the respective software is connected only afterwards and a test operation of the entire plant is carried out.

Integration in the control level

The command and data communication usually takes place via the current Fieldbus interfaces. If, for example, a Profibus connection is realised, it will be possible to use the advantages of the IDENT Control with the Profibus profile DPV1. This allows for acyclic communication, reducing the bus load and making it possible to use the standardised IDENT profile. This consid-erably reduces the software engineering efforts.If the connection is, for example, realised via an EtherNet interface, not only the homepage of the IDENT Control with the device documentation can be made available in the case of problems, but remote diagnosis and error-de-pendant diagnosis messages e.g. to a wireless service telephone are also possible.
