  4. OPC Scope - Trend plots - Watch screen - Datalogging - User screens iTools - Configuration - Cloning SCADA • Wonderware • CiTech Excel - Analysis - Historical trend plots OPC -ModBus server iTools software blocks running on PC DDE OPC OPC OPC Serial Input to PC ModBus iTools Basics.

  5. iTools Advanced Features • OPC client/server architecture • SCADA integration, e.g. Wonderware & CiTech, with no additional drivers • OPC = OLE for Process Control {Faster than DDE} • OLE = Object Linking and Embedding • Support for DDE included • ActiveX components • User can build own views using Visual Basic etc.

  6. Operating Systems • Windows 95 • Windows 98 • Windows Me • Windows NT 4.0 (SP4 or later) • installation requires Administrator privileges • Windows 2000 • installation requires Administrator privileges

  7. System Requirements • minimum 40MB hard disk space

  8. iTools Editions • DEMO - no Product Key required • some functions disabled • communications limited to 30 minutes • STANDARD • all features available except third party access to the OPC ModBus server • OPEN • all features available with third party access to the OPC ModBus server. Use this edition if Wonderware or some other SCADA is a client

  9. iTools applications - advanced • ModBus OPC Server • communications driver • iTools Remote • launches iTools with option to connect to a ModBus OPC Server running on a remote computer • IDM Manager • may be used to install support for additional device types • IDM = Instrument Descriptor Module • provides complete characterisation of a device type/version • iTools Installation Diagnostics • helpdesk aid

  10. iTools communications • iTools communications driver is a ModBus OPC server • Supported communications protocols: • Serial ModBus (RS232 or RS485) • Eurotherm factory communications • based closely on serial ModBus • ModBus TCP • for use over Ethernet TCP/IP • typically requires a ModBus TCP to serial ModBus gateway, e.g. a Lantronix CoBox • No support for communications over ProfiBus

  11. Start the iTools program from the default install location.

  12. SEARCHING FOR MODULES ON NETWORK Ensure the modules are on the network and powered. Click on the SCAN button as shown to search for modules attached to the network.

  13. The Enable Background Scan window appears. This allows for scanning to commence from node address 255 or from an address (usually 1) that you select. The Connect to Configuration station is another device available from Eurotherm for fast large volume configuration projects allowing fast un-powered configuration.

  14. Once the scan is started it will find all modules on the network. This scan found a Eurotherm 2704 on serial com 4. The window shows the Browse parameter window and the Panel View picture of the module detected.

  15. If only one module is on the network or the scan has found all modules on your network, stop the background scan by again clicking on the SCAN button. This makes your system faster as the serial comms does not have to communicate to the module as well as continue searching for new equipment.

  16. VIEWS: PARAMETER VIEW The Parameter window allow access to all module parameters for monitoring or configuration. It is selected from the drop down selection beside the Views Button.

  17. Shown in the right window is the parameter view for the process variable input on the 2704. The parameters monitors the real-time information for the PV input. The OPERATOR level access which is available in this view allows the user to vary any parameter in BLACK. All parameters in BLUE are read only. In this mode variables such as the scaling factors can be altered.

  18. To access the configuration mode to allow full calibration of the PV input, the unit must be put into the configuration mode by clicking on the ACCESS button.

  19. For safety reasons in the configuration mode all the module outputs are turned off. This pop out window advises that you are about to enter the configuration mode and that control will be halted. Click yes to continue.

  20. The device is in the configuration mode. Note the “Spanner” symbol indicating configuration mode. Notice also that a number of extra parameters are now available to the operator such as TYPE and LinTyp. These are only accessible in configuration mode.

  21. In this example the input type parameter has been selected (by double clicking on the variable). The pop out window has a list of variables that can be selected as the input type for this module’s input. Simply select the appropriate input and select OK.

  22. From the previous example mV has been selected. The LINTYP shows the linearisation options. Linear would be typically selected, but custom curves can also be selected.

  23. If a mV, V or mA input is selected, the operator can also choose complete scaling. IOL and IOH are the input electrical hi and lo, which are scaled to equal the values selected for VALL and VALH. The user can also select Units for the parameter, mV has been chosen but this could be any standard or custom unit.

  24. When a parameter is modified by the operator, as soon as the OK button is pressed the information is downloaded to the modules permanent memory.

  25. SOFT WIRING (2604 & 2704) In place of external wiring to configure I/O blocks, Eurotherm modules have the ability to “soft-wire” parameters. This allows the user the simplicity of internally ‘wiring’ any parameter as the input to another parameter.

  26. For example say you want to ‘wire’ the PV input to make it the source for the PID Loop 2. Double click on the parameter.

  27. The pop out window allows the user to choose the appropriate link or ‘wire’ from all available parameters. Here we have scrolled down to find the PV value parameter in the PV_input list found in the Standard IO menu. Select the val tag and then click OK.

  28. The scaled value on the PV input is now linked or ‘soft-wired’ as the input source parameter for the PID Loop 2.

  29. VIEWS: TOOLKIT BLOCKS (2604 & 2704) Toolkit Blocks is the term used to describe the powerful mathematics and Boolean logic capability available in the Eurotherm 2604 & 2704 controllers as well as the 2500 modular system.

  30. User values are useful as constants for alarm inputs, logic comparators or for formula constants.

  31. The ANALOGUE blocks allow for almost any mathematical function. The blocks can be cascaded to provide for the most complex of calculations. Any parameter can be soft wired to the inputs allowing for infinite configuration of the module.

  32. Available functions include: +, -, /, x, log, min, max, exp, sample & hold, hot swap, and logic select. Both inputs allow for scaling inputs as well as high and low output limits.

  33. The logic blocks provide for any digital and Boolean expression. The blocks can be used for simple AND gates or comparisons, but can also be cascaded with the analogue blocks to allow for true hybrid control.

  34. Available functions include AND, OR, XOR, Latch, =, >, <, >=, <=. For Boolean functions, both inputs can be inverted if required.

  35. As with other parameters the inputs of the parameters can be soft wired from any parameter in the same drag and drop method, or double clicking the input to reveal the pop-out parameter selection window.

  36. VIEWS: USER PAGES (2704 only)

  37. The graphical screen for the high specification hybrid controller model 2704, can be configured with 8 custom screens. iTools 4.20 is now provided with a simple method of screen generation, which provides simple configuration with real-time viewing.

  38. In the configuration mode the screen is generated from one of 7 basic formats.

  39. Here the screen position 10 is shown in white (selected). As per other inputs, soft-wiring allows any parameter to be wired to this alarm point. Here the selection of the output from User Alarm 2 is selected for the position 10 on the screen.

  40. The position is now provided with information text providing the operator with simple to read screen information. Here the word “cell” is to be used for the position 10. Thus when the alarm is activated in this position the operator will be able to read that the ‘cell’ has a problem.

  41. Only in the configuration mode can the user screen be set up. When the system is returned to the normal operator mode (by clicking on ACCESS again), then the actual screen can be seen.

  42. Here is the user screen as programmed. Note that only fields that have parameters soft-wired to them will be shown.

  43. VIEWS: WATCH RECIPE Watch Recipes allow the user to monitor parameters from different sections of the parameter list on a single screen. Any parameter can be added to the watch recipe which is in effect a custom menu.

  44. Simply drag any parameter from the left hand ‘explorer’ style menu to the right hand WATCH MENU window.

  45. The parameter then appears in the watch menu, with the data in realtime.

  46. Add as many parameters as required to the Watch window. This allows a custom menu to be developed, with parameters from any sub menu. PARAMETERS MAY ALSO BE FROM DIFFERENT MODULES ON THE NETWORK.

  47. The new watch window can be saved so that it can be simply opened at a later time without the need to recreate the menu.

  48. The watch window also allows for taking ‘SNAPSHOTS’ of the menu data.

  49. Each time the ‘snapshot’ button is pressed a DATA SET is generated. This allows events to be captured.

  50. Thus sequences of data changes can be followed for later analysis if needed.
