Multi-Site (Master/Slave) Recipe

Before following the recipe instructions in this section, first make sure you are familiar with Basic Recipe Techniques.

Many recipes will require a large number of similar measurements to be taken on a single sample. The user may wish to create a recipe with a large number of sites, yet have a single measurement node control the scan parameters for all of the sites.

This example recipe will demonstrate how to create a recipe where the scan parameters from a master site are also used on many other slave sites. Should changes to the recipe be necessary, the user only has to change the scan parameters for a single site and they will affect all of the other sites in the entire recipe as well.

The Master-Slave.rcx (see Figure 1) recipe will:

• Perform a cantilever tune
• Engage, scan, capture, and withdraw on six different sites
• Create a report

Figure 1: Multi-Site Recipe

Name the Capture and Report Directories

Before creating a new recipe, create a new folder in the Capture directory to be the destination folder for the captured images and created reports. Name this directory Master-Slave.

Create a new recipe. In the My Recipe node, change the destination for the Capture and Report directories to the newly created directory, D:\Capture\Master-Slave:

Setup the Real-time Configuration

1. Create a Real-time Configuration node as a child node of the My Recipe node.
2. Create Auto-Tune and Alignment/Origin nodes as children of the Real-time configuration node.
3. Use the Professor to align the cantilever and teach the origin location of your sample.

Create the "Master" Site

1. Create a new site as a child to the Alignment / Origin 1 node.
2. Create new Measurement and Capture Image nodes as child and grandchild nodes to the new site.
3. Rename the site Master Site, and rename the measurement Master Measurement. Rename nodes by selecting the Name property and typing in a new value.
4. Use the measurement professor to teach the parameters for the master measurement.

Create the Slave Site

1. Create a new Site node under the Alignment / Origin 1 node.
2. Create Measurement and Capture Image nodes under the new site.
3. Rename the new site Slave Site and rename its child node Slave Measurement.

Do not program the Slave Measurement node. Leave the parameter Load These Parameters When Run set to No:

Copy and Paste The "Slave" Site

1. Right click on the Slave site and select Copy.
2. Right click on the Alignment / Origin 1 node and select Paste.
3. Repeat the copy and paste process to create a total of five slave sites, such that there are a total of six sites with the master as the first.
4. Create a report as a child to the root node.

After the recipe has been run, there should be six captured images as well as the report created in the Master-Slave directory. Because all of the Capture Image nodes were the same for all six sites, there is no difference between which images came from the master and which came from the slave sites:

Changing the "Master Measurement" Parameters

The user may change the measurement parameters for all of the sites by altering those for the Master Measurement node. This is done by selecting the Master Measurement node and engaging the professor:

Because the parameters have already been programmed, the professor asks if the user would like to load the previously saved values, or to leave the system in the current state.

Regardless of the choice, the scan parameter window will open and the user has the opportunity to view and change the scan parameters. The new parameters will then be saved to the Master Measurement node and these parameters will be loaded when the first site's measurement begins.
