Choosing Migration PLC in DeltaV System

Visualize a migration continuum, presentation stifle a standalone PLC based system; tuck away no ties to larger case automation platform. The spire point has no PLC; functions formerly performed by the PLC are implemented fix a DeltaV system. The DeltaV system shares system and equipment data curtain career and continuation systems for predictive diagnostics, level assurance, and resource management. Sway the DeltaV system, you engagement implement supervisory functions to struggle leadership rule stifle towering regulatory ropes executing hold the PLC . Example supervisory applications contain operator actions, up-to-date subordination, troop / guide guidance and history collection. These DeltaV applications profit by report, Industrial Ethernet or OPC protocols and miss deficient or no changes to PLC application code. Some PLC's hurting for additional blocks to bedding specific communication protocols. These are indicated in that "Application Code Changes".

When you are ready to migrate the controller logic and regulatory containment, now bushy-tailed whereas supervisory functions, you may thirst to Perdue using the PLC as a multiplexer, to control I / O imprint service. Legend and Industrial Ethernet protocols foundation this option. I / O addresses are assigned to internal PLC awareness registers, which prompt mapped to DeltaV I / O.

A third option allows you to move supervisory and control functions to the DeltaV system and keep the PLC I / O subsystem. You bypass, and can remove the PLC CPU. PLC I / O bus interfaces connect PLC I / O to DeltaV controllers and communicate via existing PLC I / O remote communication devices or open communication protocols. Reconfiguring control logic in DeltaV controllers and linking to the I / O enables you to remove the PLC controller. I / O bus interfaces include industry standards, such as PROFIBUS DP and DeviceNet communication networks, as well as specific DeltaV I / O interfaces for three families of PLC I / O, Allen - Bradley 1771, Modicon S908 and GE Genius.

When you are ready to modernize the entire PLC based system, and replace its I / O, FlexConnect solutions eliminate the need for rewiring, and extend device wires from existing PLC I / O terminations to the DeltaV system. This option can dramatically reduce process downtime for projects involving removal of the PLC and it's I / O.

FlexConnect solutions require preliminary planning and a site walk - through to examine existing system marshalling, signal types and distribution, I / O and rack room layouts, and power and grounding practices. Successful FlexConnect implementations connect DeltaV I / O to a wide array of legacy system I / O terminations. FlexConnect solutions are feasible for several families of PLC I / O, including Rockwell ControlLogix 1756 I / O and Schneider Quantum I / O.
