Dual Redundancy in Eurotherm T2550 Control Unit

Eurotherm's T2550 control unit has automatic dual redundancy options, that it claims, improves process efficiencies and protects against controller or communications failures. The unit now also provides secure data recording with dual redundancy at point of measurement.

The redundant logging feature records data to the internal flash memory of the T2550 processor. The data can then be pushed, as secure tamper resistant historical data files, to a remote file server using FTP (File Transfer Protocol) , with support up to three servers.

Alternatively data can be pulled from the product using Eurotherm Review software. Eurotherm Review can be used to create a graphical representation of the process data. Data can be recorded at one-second intervals and pushed to a server as and when required, depending on the archiving strategy adopted. The T2550 also supports online configuration changes to a running database allowing additional parameters to be added to the Data Management strategy as and when required.

'Online reconfiguration provides a useful foundation for enhancement of the deployed control system and enables modification of the systems application database when it is running,' explained product manager, Darren Mardell. 'It enables active strategy components to be modified, wrapped with additional functionality or replaced with a different implementation'.
