  1. iTools Graphical Wiring

  2. iTools Workshop - getting started Start iTools and from the New File menu choose 3504 v1.04 programmer

  3. Firstly click on the By using the mouse of your PC press the button. Change the zoom to 50% Left click your mouse and dragging down to highlight the whole block diagram and wires. Then press delete You should then have the blocks and wiring greyed out. You will need to press which is the send to device command to clear the page iTools Workshop - graphical wiring editor

  4. iTools Workshop - module selection Go into ModIDs in the Browse and configure module 1 to DC Control (242) Then go back to the Blocks view

  5. The PV input channel(double click on function block) type is set to Volts, • linearisation is linear and the units are %. The range is set so that a 0-10Vdc • input represents 0-100% with 1 decimal point. Filter time is set to 10seconds. iTools Workshop - creating a simple control loop • In configuration mode. Drag the PV Input from the IO list, Control Loop and IO Module 1A from • the template menu on the left hand side of your screen and place them on the blank page Control type is set to PID only. Range low and high should be 0-100. Put control loop in auto as default. Note the 3500 for safety reasons is shipped configured in manual as default Output channel should be ranged 0-10Vdc and the OP display 0-100%

  6. Press to take the dotted wire to hard wire iTools Workshop - wiring between blocks Make wires as shown below by left click on point or select from list then drag and click at destination Wire PV to Main.PV Wire OP.Ch1OP to 1A.PV

  7. Configure Module two to be relay OnOff • Drag Alarm Block and Module 2 onto the page. • Configure alarm to be • Absolute High and set the threshold to 80. Wire Loop Main PV to Alarm In • and Alarm Out to Module 2A PV as shown below Press to take the dotted wire to hard wire iTools Workshop - adding a high alarm

  8. Press to take the dotted wire to hard wire iTools Workshop - hot swap module • Configuring a Hot Swap PV function using Maths block • The Hot-Swap function allows a second input to be used as the loop PV if the main input fails. • Configure Module 3A to be the same input range as the main PV input then drag it onto the page. • and • Drag Math2 onto page. Set as ‘Hot Swap’ then wire as shown, to remove the old wire from the IO.PV • click on the wire and delete it. The wire will be greyed out. Then wire the PV to the In1 of the • Maths2 block.

  9. iTools Workshop - programmer enable In the browse menu under Options enable the programmer by putting a 1 instead of 0 against ProgEn

  10. Press to take the dotted wire to hard wire iTools Workshop - adding a programmer Adding a programmer Drag Programmer onto page. Some default wires connecting the programmer block to the loop are automatically created. These links are required so that the programmer can detect holdback and servo start to PV.

  11. In iTools open the setpoint profile editor by clicking the programmer icon on the tool bar. You will now see the program editor screen as shown Add a new program segment using the plus icon on the toolbar iTools Workshop - editing a programmer 1

  12. The segment information will now be displayed iTools Workshop - editing a programmer 2 Create a Rate segment, holdback may also be specifically configured for this segment. Now add a Dwell segment and a Rate segment. NOTE: -All programs contain an implied end segment of dwell. If a reset end segment is required an end segment must be specifically inserted.

  13. To change the program names edit using the program name field Each segment contains 8 event outputs, these may be configured using the event out section of the segment editor. And may be viewed using the digital profile view iTools Workshop - editing a programmer 3 You should now have a simple ramp dwell profile with a reset end segment similar to the one shown below.

  14. The event outputs may also be edited at this point by pressing iTools Workshop - digital output profile view The 3500 programmer model supports segment types of; End – Dwell End segment Time – time to target segment Rate – Ramp rate segment Dwell – Dwell at given setpoint Step – Step to given setpoint Call – Call out to another program. NOTE:-A program may be any combination of time and rate segments.

  15. Press to take the dotted wire to hard wire iTools Workshop - configuring the display Drag the Instrument Block onto the page and wire the loop PV to the display Bar.Val

  16. Press iTools Workshop - adding a comment Drag a comment onto the page and create a meaningful sentence

  17. Press to take the dotted wire to hard wire iTools Workshop - adding a monitoring point Drag a monitor onto the page and link it to a value. Hover the mouse over the right hand side of the monitor box. Left click then connect to a parameter
