Eurotherm® T2750 PAC Process Controller from WATLOW®
The extensive range of process controllers offered by WATLOW® includes the industry-leading T2750 PAC Programmable Automation Controller developed by Eurotherm®. This provides highly versatile and modular solutions for creating complete distributed control and recording environments.
The T2750 PAC provides high-performance control with cost-effective redundancy options that make it one of the most cost-effective high-availability PACs on the market. It combines powerful instrumentation, control units, and an I/O system to handle continuous analog, logic, sequential control, batch management, secure data recording at point of measurement, and setpoint programming.
Notable features include Historian “Store & Forward” data recording at I/O level, high Integrity data recording, multi-setpoint programmer, Enterprise Control system, and redundant operation with E-Sync technology. The IEC61131-3 style software tools include a rich function block library.
Data Integrity and Integration
The T2750 PAC provides powerful programmable application capability to support development of systems that can easily integrate with existing platforms and third-party equipment as required.
A particular feature is secure redundant data recording that allows data, alarm information and messages to be recorded at the point of measurement, with all data being time-stamped as it is recorded, satisfying regulations such as the FDA 21CFR Part 11 and the Data Integrity ALCOA+ guidelines that state that data should not just be Attributable, Legible, Contemporaneous, Original, and Accurate but should additionally be Complete, Consistent, Enduring, and Available.
Infinite archiving
The optional redundant processor and power supply capabilities of the T2750 PAC ensure that while the process is running, critical data are constantly being stored, maintained and made available over the communications network. Should comms be lost for any reason, the data are still available for Forwarding when communication is restored, ensuring that any holes in the supervisory visualization software are filled to provide a true picture of the process.
Internal flash memory can store up to several months of data that can be pushed over FTP to either primary, secondary or tertiary servers – effectively providing a potentially infinite archiving capacity.
Data can also be pulled into multiple sources where it is needed for batch, process and analysis reporting, and forms the primary source of Raw Data archive for the FDA or similar organisation.
The T2750 PAC can connect seamlessly to a data historian using store-and-forward technology. This enables automatic fill in any data loss from the secure Attributable files at the instrument when communication to the historian is restored.
Reporting and analysis
Software such as “Eurotherm Reviewer” can acquire the data for legible analysis and inclusion in a database, viewing, printing or for report preparation and publication, with packages such as Eurotherm Dream Report™.
Whether a standalone or a plant-wide solution, the Distributed Control System (DCS) T2750 PAC offers high performance with scalability, distribution and integration to suit the requirement. It provides peer-to-peer communications and units can be distributed throughout the plant with simple configuration from a single database. A wider, integrated solution can be provided using Modbus RTU, TCP or Profibus communication to other products and systems.
