Description
The used HART-enabled device can execute multiple measurements in one
device. (For example, flow rate and concentration can be measured.)
The used HART-enabled device requires EEPROM Control. For details,
refer to the manual of the used HART-enabled device.
The used HART-enabled device can connect one network with another
network.
The used HART-enabled device supports a wireless HART communication.

The used HART-enabled device supports coherent 8-way phase-shift
keying (C8psk) protocol aside from FSK HART protocol. The A/D converter
module does not support C8psk.
The used HART-enabled device supports coherent 8-way phase-shift
keying (C8psk) protocol in the Multi-drop mode only. The A/D converter
module does not support the Multi-drop mode.
