HART-Fast-Mode
AI-DI 16/DQ16x24VDC HART HA supports the processing of HART commands as SHC
sequence ("Successive HART Command").
If a HART command with set SHC bit is detected, this channel is reserved for external HART
commands for approximately 2 seconds. No internal HART commands are output.
Burst mode
The AI-DI 16/DQ16x24VDC HART HA does not support burst mode. HART commands with
set burst bit are ignored and are not forwarded to the connected field device.
