Configuring a 3500 Using iTools

3

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

4

iTools Workshop - graphical wiring editor

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.

which is the send to device command to clear the page

You will need to press

5

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

6

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

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.

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%

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

Press to take the dotted wire to hard wire

iTools Workshop - adding a high alarm 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 - hot swap moduleConfiguring 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.PVclick on the wire and delete it. The wire will be greyed out. Then wire the PV to the In1 of the Maths2 block.

Press to take the dotted wire to hard wire

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

11

iTools Workshop - adding a programmer

Adding a programmerDrag 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.

Press to take the dotted wire to hard wire

12

iTools Workshop - editing a programmer 1

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

13

iTools Workshop - editing a programmer 2

Create a Rate segment, holdback may also be specifically configured for this segment.

The segment information will now be displayed

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.

14

iTools Workshop - editing a programmer 3You should now have a simple ramp dwell profile

with a reset end segment similar to the one shown below.

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

15

iTools Workshop - digital output profile view

The event outputs may also be edited at this point by pressing

The 3500 programmer model supports segment types of;End – Dwell End segmentTime – time to target segmentRate – Ramp rate segmentDwell – Dwell at given setpointStep – Step to given setpointCall – Call out to another program.NOTE:-A program may be any combination of time and rate segments.
