Integrating the transmitter via the HART
®
protocol
For secure HART
®
communication in accordance with functional safety as defined in
IEC 61508 (SIL mode), measured values are sent securely from the transmitter via the
HART
®
protocol to a connected control system where they are processed further in a
secure manner. Secure HART
®
communication works using special HART
®
commands
that are only available in the SIL mode.
The secure HART
®
protocol includes technologies, that are licenced by Rockwell
Automation.
For more information please refer to the Functional Safety Manual SD01172T/09.
