Off-line Versus On-
line SMV
Configuration
The SCT 3000 allows you to perform both off-line and on-line
configuration of SMV transmitters.
• Off-line configuration does not require connection to the transmitter.
By operating the SCT 3000 in the off-line mode, you can configure
database files of an unlimited number of transmitters prior to receipt,
save them either to hard disk or a floppy diskette, and then download
the database files to the transmitters during commissioning.
• An on-line session requires that the SCT is connected to the transmitter
and allows you to download previously-configured database files at
any time during installation or commissioning of your field
application. Note that you can also upload a transmitter’s existing
configuration and then make changes directly to that database.
Off-line Configuration
Procedures
Refer to the SCT User Manual (on-line) for detailed procedures on how to
off-line configure SMV transmitters using the SCT 3000.
