12 Measurement
The Measurement table provides a comprehensive overview of all cached parameters and values of
all sub-devices.
• As the the list is stored in a non-volatile memory, the card and channel number assignment
will remain the same after a restart of the gateway or software
• The dynamic values of each sub-device (analogue value, PV, SV, TV, QV) are cached by the
gateway only if the sub-device publishes these values
• After a network restart, the instrument list needs time to rebuild. During this time, some
information is set to 0 or replaced by wildcard characters
• To remove a device from the list, use the Instrument List, see Chapter 10.1
Whenever a new wireless device joins the network, it is automatically inserted into the list. Wired
devices connected to a WirelessHART adapter are also inserted.
1 Click on the Measurement leaf to open the dialogue:
– In FieldCare right click on the Fieldgate SWG70 node and select Observe
– The significance of the parameters is described in the table below
Parameter/Field Meaning
Long Tag Identifies Fieldgate within the plant network
– For devices less than HART 6.0 the Message field is used as the long tag
IO card Identifier of Fieldgate card used by the device
Channel Identifier of card channel used by the device
Device Type Designation of connected device
Status Communication status of the associated device
– Connected
– Flashing: Device connected, being identified
Continuous: Device connected but not identified
– Communication failure
Dev. Status Device status of the associated device
– Good
– Out of specification
– Failure
The device status displayed in the Operating Modes list may differ from the actual device
status because the HART status bits may be interpreted differently.
Loop current Current in mA (for HART Multidrop = 4 mA)
PV Primary value of the device
SV Secondary variable of the device
TV Tertiary variable of the device
QV Quaternary variable of the device
"+", "–" Expands or contracts the tree view
