NOTE
The sub-device scan is only performed after a power-up or reset of
the VECTOR V1100. If wired-HART devices are added to the loop
after the VECTOR V1100 is powered, execute the Scan for
Sub-Devices method or reset the VECTOR V1100 to detect them.
The VECTOR V1100 can support a maximum of eight sub-devices.
If more than eight wired-HART devices are detected, only the first
eight devices are used.
Scan Start Address
This is the first HART polling address that is used when a scan for sub-devices is performed.
Scan Stop Address
This is the last HART polling address that is used when a scan for sub-devices is performed.
Scan for Devices (method)
This method performs a scan for sub-devices connected to the VECTOR V1100, across the
HART polling addresses defined.
This method allows for the existing sub-device list to be either retained or erased prior to the
new scan.
4-20 mA Settings
The VECTOR V1100 has the ability to measure the loop current from field devices when wired
in a loop powered mode. The VECTOR V1100 can be connected to analog only 4-20 mA field
devices (with no HART capability) and report this loop current value to the wireless HART
network.
The VECTOR V1100 can convert the 4-20 mA value read from a field device into engineering
units that are reported to the wireless HART network as the Primary Variable (PV) of the
VECTOR V1100. The VECTOR V1100 can also implement a lookup table to linearize this
conversion.
PV Units
The engineering units that the VECTOR V1100 PV will be reported as.
PV Linearization Mode
This can be set to Linear or Special Curve. If set to Linear, the PV Upper Range Value and Lower
Range Value is the values in engineering units that correspond to the 4 and 20 mA points, and
a basic linear calculation is performed to convert the measured loop current to engineering
units.
