3.2.3 Smartline Configuration Toolkit (SCT)
The SCT supports several Smartline products which use the DE protocol, including
the
STT350,
STT25M
configuration/data are a subset of the STT350, most functions are supported by the
current version of the SCT software. The only confusion which may occur is if you try
to configure the STT250 for functions which are available only with the STT350
transmitter, as shown below.
•
Sensor types C, D, Ni/NiMo, Radiamatic, Pt500, Ni500, Cu10 and Cu25 are only
available with STT350.
•
External cold junction compensation is only available with STT350.
•
High/Low PV read is only available with STT350.
•
SCT does not support HART protocol and should not be used with Model
STT25H.
•
The STT25M cannot be changed from analog to digital DE mode.
To access to the new functionalities of the STT25M and STT25D, you need a
SCT3000 Version 154 or greater.
The procedure below outlines the steps to set the three new configuration options.
There are two methods to configure the STT25M and STT25D new functionalities,
both using the Generic Property Sheets.
•
Method 1
Open the BLANK Generic Property Sheets called BLANK.GDT by selecting the "File -
New" menu which displays the "Add File Template". Select "Generic Templates" TAB
and BLANK.GDT file.
