HART function
8.1 Use
• "HART gate" parameter
You can use the "HART gate" parameter to switch on the HART function (HART
communication) for the I/O module. The "HART gate" parameter acts as a fail-safe "main
switch" for the complete module.
• "HART activated" parameter
You can use the "HART activated" parameter to enable or disable the HART communication
from the affected channel of the I/O module to the HART field device.
The parameter is not safety-related, meaning that fail-safe deactivation of the HART
communication is not possible with this parameter.

WARNING
Activation of HART communication
Release the HART communication only if your system is in a state in which a possible
reconfiguration of a HART field device is safe.

WARNING
Impact of a connected HART handheld
Note that the "Off" setting of the "HART gate" parameter is bridged by a connected HART
handheld.
