7.2 Operating via FDT

SITRANS LR250 (PROFIBUS PA)

90 Operating Instructions, 01/2014, A5E32221386-AB

7.2

Operating via FDT

FDT is a standard used in several software packages designed to commission and maintain field

devices. Two commercially available FDTs are PACTware and Fieldcare.

Functionally FDT is very similar to PDM. See Operating via SIMATIC PDM (Page 59) for more

detail.

● To configure a field device via FDT you need the DTM (Device Type Manager) for the device.

● To configure a field device via SIMATIC PDM, you need the EDD (Electronic Data

Description) for the device.

7.2.1

Device Type Manager (DTM)

A DTM is a type of software that ’plugs into’ FDT. It contains the same information as an EDD

but an EDD is independent of the operating system.

7.2.2

SITRANS DTM

● SITRANS DTM is an EDDL interpreter developed by Siemens to interpret the EDD for that

device.

● To use SITRANS DTM to connect to a device, you must first install SITRANS DTM on your

system and then install the device EDD written for SITRANS DTM.

● You can download SITRANS DTM from the Siemens service and support website. Go to
