Description
Application on which the plant management or ope-
rator system is running. An OPC-DA client can also
be running here.
Host application for the FDT frame.
Device which provides the connection between seri-
al Ethernet and RS 485. Since the FDS works on a
serial COM port, a converter is needed to connect
the FDS with the RS 485 diagnostic bus in the cabi-
net.
Description
Standardized interface allowing access to DCS data
(OPC = OLE for Process Control). Integrated into
the FDS.
Communication protocols used on the Internet and
on most commercial networks.
Description
The FieldConnex
interface and a data access coordinator for the Dia-
gnostic Module HD2-DM-A, it includes the OPC-DA
service.
The FDT specification defines the interaction of
DTMs with host computers or software. An FDT fra-
me application is a PC based software including
many DTMs for configuration monitoring and pro-
gramming of field devices. Both the Diagnostic Ma-
nager DTM and the Gateway DTM run in an FDT
environment.
A DTM is a device configuration and management
software. It contains a graphic user interface and
configures and diagnoses devices. DTMs are em-
bedded in an FDT frame application, such as PAC-
TM
T
or in a DCS with an FDT interface. The DTM
ware
for the Advanced Diagnostic Module is called Dia-
gnostic Manager.
