Emerson Ovation OCR3000 DCS Controller

Product Overview

Hardware architecture innovation: merging processors and IOICs (I/O interfaces) into a single module; The backplane integrates high-speed redundant communication channels between the primary and backup controllers, eliminating the need for external Ethernet cables for redundant synchronization.

I/O capability: Supports up to 16 local I/O branches, all 16 branches can be scanned in parallel, greatly improving I/O scanning performance; Compatible with all older Ovation I/O modules.

Compatibility: The application layer program is fully compatible with OCR1100, and the original control pages, logic, and databases can be directly migrated and reused.

Network hardware, choose one backplane version:

Version 1: 4 RJ45 copper ports per controller;

Version 2: Each controller has 2 RJ45 copper ports and 2 SFP optical ports.

Firmware Security: All controller firmware supports cryptographic signature verification to prevent firmware tampering.

Optional standalone controller software toolkit: It can run as a standalone controller without building traditional Ovation networks and databases.

Process control function

Supports all Ovation traditional control algorithms, with added support for advanced algorithms such as Model Predictive Control (MPC), Fuzzy Logic, and Neural Networks; Complete Function List:

PID continuous regulation, sequential function diagram SFC, Boolean logic, special timing logic

Advanced control: MPC model predictive control, fuzzy logic, neural network algorithm

Data collection and SOE event sequence recording

Sensor limit check, process point alarm, engineering unit conversion, process point database storage, tagout

Cold end compensation, local/remote I/O interface

Control task execution

Up to 5 control tasks, all 5 tasks can have custom scanning cycles; Cycle range: 10   ms~300   s, step size 10   ms; each task includes I/O input scan, control scheme operation, and output scan.

The maximum number of process points that can be generated is 64000 (with an OCR1100 upper limit of 32000 points, doubling the number of points).

Software License: Also supports authorization extensions for simulation controllers, advanced controllers, and virtual controllers.

Third party device interconnection (new capability)

The onboard built-in Ethernet protocol driver does not require additional hardware and can directly interface with third-party intelligent electronic devices (IEDs) such as smart inverters, weather stations, relay protection devices, motor control centers (MCC), as well as third-party PLCs, PACs, RTAC, etc. through Ethernet.

Redundancy mechanism

Support controller redundancy and network redundancy; 24VDC redundant power supply is provided to the main and backup controllers respectively.

Backplane integrated high-speed redundant communication channel: The main backup is synchronized with the database, variables, and tuning parameters through the internal high-speed link of the backplane; Cancelled the external Ethernet connection between the primary and backup.

Retain watchdog detection and Bumpless Auto Fail over, and automatically enter standby mode after the fault controller is repaired and powered on.

Compatible with remote node interface RNI; The support for the remote node controller of the RNC requires subsequent firmware versions in conjunction with the new MAU components.
