IEC PAS 62453-2:2006 pdf download Field Device Tool (FDT) interface specification – Part 2: INTERBUS communication
Scope
This part of IEC 62435 provides information for integrating the INTERBUS@ protocol into theFDT interface specification (EC 62453-1)

3General
NTERBUS schemas are required to define the structure and semantics of the protocolspecific data transferred via XML documents on the FDT interfaces The schemas are basedon definitions given in the INTERBUS specification. Furthermore, they contain additionainformation about the device that is needed by systems to configure INTERBUS links and toestablish communication between the INTERBUS master and the INTERBUS slave devices
NOTE For details of the INTERBUS specification, see the lEC 61158 fieldbus series and the “Reference ManualPeripherals Communication Protocol” available from INTERBUS Club’ Deutschland e.V.

6 FDT CATID
For DTMs supporting the INTERBUS and INTERBUS PCP communication protocol, the following Component Category is added to the existing FDT CATIDs.
7 DTM information
Within the name space of the INTERBUS specification there are no unique identifiers for device types, subdevice types and manufactures defined. The following mapping of FDT identifiers to INTERBUS related information must be used.
In order to enable an easy assignment of an INTERBUS device DTM to a scanned device it is recommended to use matching device information data. The element in the DtmInformation document must contain the same data as returned in the PCP service “Identify_Confirmation” (see table below).
7.1 FDCML information
The FDCML information is a type-specific information and not instance-specific. It is not stored with single slave instances or in a global accessible file. It is provided by the DTM at IDtmInformation. On method GetInformation(), a DTM of an INTERBUS device provides the FDCML information within its XML document (in the attribute “fdt:DtmDeviceType/@deviceTypeInformation“).
