the current station and the station you want to synchronize. This link can be a direct link over
RS232, TCP/IP, or over line-of-sight radio. In other words, the following communications device
types that you can set up under the Communications menu are supported: DIRECT, RADIO, SSP,
and TCP/IP.
TagName
Specify the name of the tag to retrieve. When the tag refers to a Tag created in a basic
program, use the same name you used in the Declare Tag statement. When the tag
refers to a measurment output, use the name of the output.
DevicePort
Use DevicePort to select the communications device to use to retrieve the tag. Only
NONE, DIRECT, RADIO, SSP, and TCP/IP device types will be shown as selectable device
types. The system always has a TCP/IP device type (the LAN is always “installed”).
However, the other device types will only show up once you have set them up on the
Communications menu.
Specify a device type of NONE when the tag is local.
PathURL
This property specifies the path to the station containing the tag. The path can be a
simple station name, or a station with full path information included (such as
\patha\pathb\stationx). When the DevicePort selection is TCP/IP, enter the URL to the
target station.
IPPort
If TCP/IP is the current device type, then the IPPort property is displayed. This property
allows you to specify the IP port of the target station. This should typically be left to 23
(telnet).
UserName
If TCP/IP is the current device type, then the UserName property is displayed. This
property allows you to specify the user name to use when logging in to the target
station, before the set-time message is sent.
Password
If TCP/IP is the current device type, then the Password property is displayed. This
property allows you to specify the password to use when logging in to the target station,
before the get tag message is sent.
DiffResistance (Differential Resistance)
This input type is used to measure Differential Resistance sensors, such as those made by
Carlson Concrete Instruments for Dam Safety and concrete structure monitoring applications,
where stresses and strains on the structure are monitored and recorded, and is typically used in
combination with the Differential Resistance measurement type.
This measurement requires a special add-on board to aid in the precision measurement of the
analog inputs by the 8310. Please contact Sutron customer service for more information on
obtaining board.
