All Hart smart devices have valuable data for improving plant operation every second of every day.
Hart devices are real-time data servers with two simultaneous communication channels on the same wire:
• 4-20mA analog channel for fast
data transfer of primary variable control signal.
• Hart digital channel for real-time device status, diagnostics, multi-variable process information.
Real-time connection to both communication channels unlocks the value of intelligent device information and secures control loop integrity.
