Redul FDT Gateway

The module is a gateway for the communication of the FDT-based software (the most common is PACTWare) with the field instruments. It complies in full with the FDT 2.0 specification and connects to the Redul controllers using proprietary Redul HART Gateway protocol.

FDT (Field Device Technology) is the interface specification for open data exchange between field devices and automation systems, which is standardized by the international IEC 62453 and ISA 103 standards. In field device technology, the terms DTM (Device Type Manager or device driver) and FDT frame application are especially important.

FDT provides a common platform for data exchange for all device drivers (DTM) available according to this standard. This allows full access to all device functions provided by the DTM via different network hierarchies. This means that each device can be configured, operated, and maintained via a standardized user interface in its main features—regardless of the manufacturer, device type, or communication protocol.

FDT technology does not require any specific alterations to the field devices. The communication protocol supported by the device and the device properties are mapped in full by the FDT technology on the PC using software.



The module provides complete view of the Redul-based system (modules, channels) to the FDT-based software and user can connect to any instrument indicating its location in the system and providing DTM configuration file from the instrument manufacturer.

Each request from the upper-level software is packaged into a container, according to the specification and containing data in the format specific for the field instrument. Format for the instrument is provided by the DTM configuration file.

Having received the container, the module forwards it to the instrument and then delivers communication back from to the configuration and monitoring tool.
