Invensys Operations Management has unveiled new features of the I/A Series distributed control system (DCS) that enable easier and faster control in the field (CIF).

Invensys passed the requirements of the Fieldbus Foundation Host Interoperability Support Test in August, and has implemented engineering and performance innovations that go beyond those requirements to help clients receive maximum benefit from CIF deployment.

The Invensys Fieldbus implementation is a platform solution offering fault tolerance, easy configuration and device management.

It supports the use of standard, enhanced and custom fieldbus block types to make full use of the algorithm capabilities provided by device vendors.

Configuring control algorithms directly into field devices improves loop performance by eliminating transport time in data exchange between field devices and the host control system.

The customer can choose to use function blocks in the field devices, the DCS or both, providing greater flexibility and efficiency in many control strategies.

The Fieldbus Foundation’s host registration program tests the host’s ability to support standard function blocks and features in Device Descriptions and Capabilities Files.

Benefits include reduced engineering time through custom and generic engineering templates, which can be nested many levels deep, allowing function-block flexibility to be contained in the device template, device-specific applications or in a function-block toolset for more generic mixing and matching.

Faster response to operator changes, by caching all standard parameters in the I/A Series control processor, gives instantaneous read access to DCS applications, such as HMIs or historians.

Dynamic values are read into the processor every 10sec, with operator change commands written upon change, minimising the inherent delay caused by remoting PID function blocks to field devices.

With flexible mixing of control in the field or the host, users interact with a consistent set of standard or custom blocks, connecting output and inputs by dragging one to the other.

Easy Foundation Fieldbus scheduling enables setting of the segment macrocycle, optimisation of timing variables and minimisation of dead time within the loop.

Rapid device commissioning via a device preparation wizard sets devices to the correct tag and address and allows fast, parallel database download into the blocks in the device, while a group mechanism saves time in placing the blocks and loops on active control.

When implemented with Invensys Infusion Field Device Manager technology, Invensys CIF becomes part of a common-device configuration, commissioning and maintenance environment that provides tools to better diagnose device problems that threaten plant uptime.

Representatives from Invensys Operations Management will display and demonstrate the company’s CIF capabilities during its North America Client Conference taking place in Houston, Texas, 21-24 September, 2009.
