14. Configuration with FDT/DTM
The pulse isolator ACT20X-(2)SDI-(2)HDO-(L) will be configured via PC according to the FDT/DTM
standard.
14.1 Concept
The FDT technology standardizes the configuration and communication interfaces between different devices
and connected systems, IEC 62453. Therefore the FDT provides a common environment for accessing and
connecting the devices features. Any device can be configured, operated and maintained through the
standardized graphical user interfaces. These functions are regardless of supplier and type of communica-
tion protocol. The FDT interface is the specification describing the standard data exchange between field
devices and PC.
A device driver with full fit the FDT mandatory interfaces are called device type manager (DTM). The DTMs
are classified for the ACT20X product family into two categories:
• Device DTMs which represent the ACT20X product family with its configuration components
• Communication DTMs which create the connection to the ACT20X over the CBX 200 hardware
The FDT Frame Application is the software program that implements all DTMs. The FDT Frame Application,
also called FDT container, provides the DTM management, navigation, user management and common
environment. The Weidmüller FDT container is called “WI-Manager”.
14.2 Hardware / Firmware
The hardware of the ACT20X product family has a jack plug for the CBX 200 hardware. The CBX 200
hardware is used for the configuration via serial port and PC. The result is a point to point connection (PC to
hardware).
