Memory Image Manager

The Memory Image Manager is used to create a file from a snapshot of the contents of the retentive memory in a Do-more controller and include that content as part of the current project. The Memory Image Manager can also download the contents of a memory image file to a Do-more controller.

By default, all of the image register regions that are marked as retentive will be included in the memory image. The retentive memory settings in the controller are modified in the Memory Configuration section of the System Configuration.

Note: the contents of a memory image are not automatically updated, they are only updated when the programmer uses one of the Refresh selections, or when a new image is generated.

Create New Image... will create a new memory image file.

Clicking the Generate New Image button will erase the contents of the current memory image file for the current project (if one already exists) then copy the contents of all image register memory that is marked as retentive to the memory image file.

The Current Image Contents list the regions of the controller's retentive memory that are currently included in the memory image.

Add Region - will open the Add Regions dialog that will list all of the image register regions that are NOT in the Current Image Contents list. Click on a region to add to the Current Image Contents list. (Ctrl-Click on multiple regions in the list to select multiple regions)

Click OK to add the highlighted regions to the Current Image Contents list.

Click Cancel to close the dialog without adding any regions to the Current Image Contents list.

Refresh Contents of Selection - will reread the contents of the currently highlighted regions from the controller and store the newly read values in the memory image (Ctrl-Click on multiple regions in the list to select multiple regions)

Refresh Contents of All Regions - will reread the contents of the all the regions in the Current Image Contents list from the controller and store the newly read values in the memory image

Delete Selection from Image - will remove the currently highlighted regions from the Current Image Contents list (Ctrl-Click on multiple regions in the list to select multiple regions)

Delete All Regions from Image - will remove all of the regions from the Current Image Contents list

Write Image Contents to PLC...

Click the Write Image to PLC to copy the contents of the current memory image to the their respective locations in the controller, overwriting whatever is in the destination locations.

Enable Automatic Download - enabling this option will download the current contents of the memory image each time Do-more Designer downloads the project to the controller if the following conditions are met:

• the controller is in STOP (Program) mode (the memory image contents WILL NOT be downloaded if the controller is in RUN mode)
   

• all of the regions in the memory image file are compatible with the current memory configuration
