Load management controls electrical costs
Power controller has a predictive load management function which is highly effective in managing power demand to control peak electricity usage.
Controller performs PID loops outside the PLC
A controller can perform PID loops outside the PLC without compromising the benefits of an integrated system, allowing temperature and pressure to be maintained in event of PLC failure.
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) - up to three servers are supported for additional security of data.
Alternatively data can be pulled from the product using Eurotherm Review software.

Temperature controllers ensure reliable products
Controlling annealing and end tempering furnace temperatures precisely is a key factor in producing steels for razor blades as well as using sensors in the moulding systems for the razor bodies.
Improve injection moulded plastics consistency
Combine a contol system with the latest melt pressure control and the user will be able to maintain the consistency of an injection molded part, said a control engineering company.
Eurotherm Review is then used to quickly and easily 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".
At the centre of the system is the LINtools configuration and engineering station incorporating graphical configuration of block structured continuous control, sequence control SFC's, ladder and graphics.
VIEW and online reconfiguration modes allow dynamic monitoring and editing of running databases and flow charts.
* Database - the instrument can automatically set up its own database, including all necessary module and I/O function blocks, based on I/O detected in the base unit.
When the detection is complete, an operational database is created and runs automatically.
A set point programmer is also being integrated into the T2550 so that users can vary set points in a pre-determined way for a specific period.
Temperature is a very common application where it is required to 'ramp' and 'dwell' the process value from one level to another over a set period of time, said Eurotherm.
The T2550 can be operated using analogue, logic and sequence control and utilised as a standalone solution or a powerful addition to a larger system.
It communicates over 10/100baseT Ethernet (ELIN) and is suitable for interlocking, signal conditioning, alarm monitoring, remote data acquisition or devolved control.
Eurotherm's proprietary LIN protocol was originally developed 20 years ago for use on COAX cable networks but has now migrated to Ethernet, which means that the T2550 also supports other protocols, including Modbus and Profibus.
Key application areas for the T2550 include: batch reactors, fermenters, Building Management Systems, glass furnaces, specialist heat treat furnaces (vacuum/retort), freeze dryers, boilers, ovens, power stations.
