manual, publication 1756-UM333.

Considerations for Asset Management Systems

The following must be considered before using the I/O modules with asset
management systems, such as FactoryTalk AssetCentre or
Endress+Hauser FieldCare systems.
• HART must be enabled before any asset management system access is
possible, including scanning for multiplexers, if supported by your asset
management software. You do not need to include HART PV or HART
by Channel data in your input tag, but you do need to check the Enable
HART box on the Configuration tab of the Module Properties dialog box.
• The Logix controller must be connected to the I/O module. If the Logix
controller is not connected, the module configuration was not sent to the
HART module, and the channel is not yet configured for HART access.
• If you use a handheld HART communicator and configuration tool, such
as Rosemount 275 or Meriam, configure the tool as the secondary master.
The Meriam handheld has a high-speed mode, which assumes it is the only
master present. In this mode, the handheld may conflict with the I/O
module. Usually, the Meriam handheld automatically detects the proper
setting, but if not, set it manually.
• The ConfigurationChanged indication in the Field Device Status is
automatically reset by the I/O module. Asset management systems might
miss this indication if they are offline at the time of a change.
• A separate configuration-changed indication is in the field device status for
the primary master (1719-IF4HB or 1719-CF4H) and secondary master
(handheld, for example). The I/O modules do not reset the secondary
master configuration changed status.
HART traffic from asset management pass-through messages or from secondary
masters slows the update rate of HART data in the controller or other
pass-through message clients. In the 1719-IF4HB or 1719-CF4H modules, extra
traffic on one channel also affects other channels.
