E+PLC takes advantage of CODESYS, a leading platform which provides a proven, efficient engineering tool. Control and Visualization are built in the single integrated development environment (IDE), reducing the time and cost of implementing a system.

Engineers have the flexibility to develop sophisticated strategies and corresponding HMI functionality, with seamless integration between the two. Advanced Eurotherm algorithms can be readily selected from a library of easily applied function blocks. The resulting solution provides a standard, open platform for application development.

Enhanced Visualization for Custom Views of the Process

For ease of use and faster setup, the fully integrated CODESYS Visualization tool offers a modular facility to create enhanced views of the plant.

  • Visualization editor with built in graphical elements
  • Easy creation of styles for custom look and feel
  • Bespoke visualization libraries for application re-use
  • Modern HMI techniques for enhanced views of simulation, operation and monitoring of the plant

Keeping Up with the Latest Technology

The CODESYS open platform approach facilitates a knowledge bsharing culture with numerous support forums.

  • Continuous maintenance and development of new technologies
  • Developed through years of specialist industry knowledge
  • Involved in committees that contribute to the international IEC 61131-3 standard

Flexible Programming on an Open PLC Platform

IEC 61131-3 Programming Languages Supported:

  • Continuous Function Chart (CFC)
  • Ladder Diagram (LD)
  • Sequential Function Chart (SFC)
  • Function Block Diagram (FBD)
  • Structured Text (ST)
  • Instruction List (IL)

Easy Engineering, Faster Commissioning:

  • Comprehensive built in libraries of function blocks
  • Unique Eurotherm libraries containing function blocks such as precision PID, autotune, setpoint programming, batch recording and archiving
  • Custom and 3rd party library support
  • Users can define bespoke function blocks and visualization elements for simplified duplication throughout the application, or for reuse across multiple applications.
  • Supports a wide range of data types from booleans to 64 bit reals, including the ability for the user to define their own data structures.

Preservation of Intellectual Property

  • Application programs are compiled in a tamper resistant format to mitigate the risk of reverse engineering

The flexibility of programming in CODESYS integrated development environment in combination with the precision control and maths functionality made E+PLC100 the most convenient solution

User Management

Access rights for individual users or user groups can be conveniently managed from within the IDE. For example, a push button visualization element could be configured to change controller settings.

Login functionality, password management and user management are available at runtime via the HMI. Password controlled access helps prevent unauthorized use.

Recipe Manager

Recipes are available for setting and watching control parameters. These can be saved, loaded and executed via visualization elements, and edited at runtime from within the CODESYS IDE. They can also be combined with the Eurotherm Batch Data Management function blocks to enable Batch processes.

Integrated Alarm Management

Alarms can be based on input signals or other PLC variables, and their conditions displayed on the HMI for acknowledgement by the user. Alarms can be grouped if required, and events can be triggered and processed from within any of the programming languages.

Triggered alarms can be recorded within Eurotherm UHH data files for historical purposes. This can be achieved utilizing function blocks in the Eurotherm Data Recording library.

Multiple Controllers within a Single Project

CODESYS single engineering and visualization environment allows simple reuse of base code, enabling multiple E+PLC controllers to be combined into a single CODESYS project, or the screens of one project to be displayed on several different HMI devices.

Program Portability

CODESYS elements can be imported and exported between projects. The capability to import or export XML files in PLCopen format is also supported, allowing transfer of code to and from any PLC that supports this open standard.

Debugging Support

The CODESYS debugging tool provides a number of useful features for validating applications, as well as real time access to running programs from the engineering environment:

  • Display of application data at runtime from within E+PLC
  • Reading, writing, and forced setting of variable values, from within editors or watch lists
  • Setting of conditional and absolute breakpoints, and subsequent code execution in single steps or complete cycles
  • Display of application data from a simulation ‘SoftPLC’ enables debugging without hardware

“I’ve been waiting for this combined functionality for a long time. There are many out of date PLC based systems in the field that require precision PID control. We can now replace these with E+PLC400 combination PLCs.”
