Measurement WirelessHART Fieldgate SWG70
108 Endress + Hauser
12 Measurement
The Measurement table provides a comprehensive overview of all cached parameters and
values of all sub-devices.
• As the list is stored in a non-volatile memory, the card and channel number assignment
will remain the same after a restart of the Fieldgate or software.
• The dynamic values of each sub-device (analogue value, PV, SV, TV, QV) are cached by the
Fieldgate 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 "Instrument
List" on page 64.
Whenever a new wireless device joins the network, it is automatically inserted into the list.
Wired HART devices connected to a WirelessHART Adapter (SWA70) are also listed.

Parameter Meaning
Long Tag Identifies Fieldgate within the plant network
– For HART 5.0 or lower, the texts in the "Message" parameter
IO card Indicates the virtual I/O card number to which the device is mapped
Channel Indicates the channel of the virtual I/O card to which the device is mapped
Device Type Displays the device type as registered at the HART Communication Foundation
Status Displays the communication status
– Connected
– Flashing: Devices connected, identification in progress
Continuous: Devices connected but not identified
– Communication failure
Dev. Status Displays the device status
– 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
