Emerson's new Rosemount® transmitter is first with logic capability to integrate discrete devices with process devices over FOUNDATION fieldbus
New FOUNDATION fieldbus device answers user need for fewer buses in plants, reducing installation and maintenance costs. CHANHASSEN, MN (July 20, 2004) - Emerson Process Management introduces the new Rosemount 848L Logic Transmitter for cost-effective integrating of logic and discrete I/O capability on a FOUNDATION fieldbus H1 segment, without the need for a separate discrete I/O bus. The 848L adds to the broad family of intelligent field devices that power delivery of project and operations savings and efficiency by Emerson's PlantWeb® digital plant architecture.
The 848L accepts up to eight direct-wired discrete inputs, plus inputs sent over FOUNDATION fieldbus; these interact within the device's logic processing capability, and drive up to four discrete outputs of the 848L. By executing logic in the 848L field device, the application can be supported in the absence of any central controller, or even fieldbus communications, providing a high level of availability. The 848L can be used in a variety of applications including motor starters, solenoid valves, limit switches, interlocks, proximity switches, push buttons, annunciators, and burner flame management.	Rosemount 848L Logic Transmitter
Twenty logic equations of the 848L transmitter enable interactions to be processed independently of the fieldbus and central controller, providing fast execution for the most demanding applications. The transmitter's discrete input block can communicate the status of any of the inputs, or the results of any of the twenty logic equations, to other devices on the bus or to the host. As a FOUNDATION fieldbus device, the I/O and logic can be configured using the same DDL based software tools utilized by other devices, reducing maintenance and training costs. As one of the components of Emerson's PlantWeb, the 848L further strengthens the digital plant architecture's proven ability to improve plant efficiency by 2% and more through delivering asset optimization, process automation, and management execution. Further cost savings, increased plant availability, and enhanced safety and environmental compliance are achieved when the transmitters are integrated into the PlantWeb architecture.
