Trend parameters

You can trend parameters in multiple locations such as in a plant historian or in AMS Machinery Manager. The method for configuring this functionality is contained in the associated software and the details of all the possibilities are beyond the scope of this manual. This manual only indicates some of the general capabilities and version requirements.

You can trend values in essentially any host that accepts Modbus or OPC inputs. Configure OPC tags and Modbus registers for wireless devices in the Smart Wireless Gateway web interface. Refer to the Smart Wireless Gateway User Manual for additional information. The settings in the gateway and the host must be consistent and entered in both locations (for example, Modbus register definitions).

DeltaV integrates native wireless I/O devices on the control network. Refer to the DeltaV documentation for more information on the required version. You can manage wireless devices as native HART devices, and trend variables accordingly. This type of installation also allows richer alerting and diagnostics because the full HART capabilities are available.

Ovation 3.3 or later also integrates the Smart Wireless Gateway with all the associated benefits of HART.

AMS Machinery Manager 5.4 or later supports HART functionality to read configuration and alert information, as well as the dynamic parameters from the CSI 9420. This allows AMS Machinery Manager to auto-discover all of the devices on the wireless mesh as well as the specific sensor configurations, units settings, and variable mappings for CSI 9420 devices.

Also, with AMS Machinery Manager and CSI 9420 devices (that are licensed for the Advanced Diagnostics application), you can trend Energy Band parameters. For more information, see Advanced Diagnostics application.

DeltaV versions prior to 10.3 and Ovation versions prior to 3.3, though not integrated through HART, accept Modbus values from the wireless devices. DeltaV also accepts OPC values.
