In addition to the HART activities outlined in the diagram, if there are HART
pass-through messages to send, they are interleaved in the auto scanning. Logix
controllers can send pass-through messages using CIP MSG instructions, and
Asset Management systems can send them. For more information, refer to the
ControlLogix HART Analog I/O Modules User manual, publication
UM333.
If the HART field device configuration is changed—from a handheld, asset
management, or device faceplate—cyclic reading of the Dynamic Variables
pauses briefly while the configuration changes are assimilated. The
HART.ChxDeviceStatus.ConfigurationChanged status is set when the updated
configuration is retrieved from the HART field device and stored in the module
to indicate that new data is available for GetDeviceInfo CIP MSG.
