The IzoT Commissioning Tool (CT) is a graphical software tool based on Microsoft Visio that you can use to install and commission a community of LON devices by simply drawing your network using the powerful and easy-to-use Visio software. As you draw your network, IzoT CT communicates with your devices to make them match your drawing. To make two devices communicate, you draw a line between them. The result is a network drawing that serves as the as-built documentation for your network.

The “IzoT Commissioning Tool” name is the name of the OpenLNS Commissioning Tool (CT) starting with release 4.1 of OpenLNS CT. The “IzoT Net Server” name is the name of the OpenLNS Server, starting with release 4.02 of the OpenLNS Server. The product names referred to by the IzoT CT and IzoT Net Server software and documentation are not all updated to the new IzoT names, so you may see references to both sets of names in the software and documentation.
This ReadMe document applies to Release 4.4 of the Echelon IzoT Commissioning Tool (CT). Following are the major new features of this release:
· Silent Install – IzoT CT is now capable of silent installation.

This section describes known problems and their workarounds for this release. Numbers in parentheses at the end of the descriptions are Echelon's internal problem tracking IDs.
If you open an IzoT CT drawing originally created with the LonMaker tool, Visio may display message the following error message: “Macros in this document are disabled because the security level is high…” If you click OK, the drawing opens, but most of the IzoT CT functionality is disabled. Workaround: To enable the IzoT CT software to work with a drawing created with the LonMaker tool, use the following steps to decrease Visio's macro security.
1. Open the Tools menu.
2. Click Options, select the Security tab, and then click Macro Security. A dialog appears allowing you to select Low, Medium, High, or Very High security.
3. Select Low or Medium security. If you select Low security, you will be able to open the drawing without a prompt. If you select Medium security, you will be prompted to enable macros for unsigned network drawings or network drawings signed by companies that have not been added to the trusted signatures list.
Visio's security level is persistent. When you change Visio's security level, it will be the security level for Visio every time it is started until you change it again. Alternatively, you can apply your own company's digital signature to any IzoT CT drawings to disable macro warnings for those drawings. For detailed instruction on how to do this, go to support.microsoft.com. (40186)
When you open an IzoT CT document, more than one instance of the document may open in Visio, or additional documents may be opened at the same time. Workaround: To prevent opening extra drawings, follow these steps:
1. On the Visio Add-Ins menu (the LonMaker menu in Visio 2003), click Synchronization/Resynchronize.
2. Select Reset Visio Workspaces.
3. Click Next.
4. Select either Only the Current Drawing to update the workspace for the current drawing only, or All Drawing Files in the Network to update the workspace for all drawing files. (40066)
When you close an IzoT CT document, Windows may infrequently report that Visio has stopped responding after closing the IzoT CT drawing. Workaround: This problem occurs after the IzoT CT add-in has properly closed the IzoT database and the Visio drawings and then terminated. As a result, the IzoT CT drawing and IzoT Net Server database are not corrupted, and you can safely close and ignore the error message. (56976)
If automation events have been disabled in Visio, the IzoT CT menus may not be displayed in Visio. Workaround: To display the IzoT CT menus, follow these steps:
1. In Visio, click the File tab, and then click Options (on left side). The Visio Options dialog opens.
2. In the Visio Options dialog, click Advanced (on left side of dialog)
3. On the right side of the dialog, scroll to the bottom, and verify that Enable Automation Events is selected under the General heading.
4. Click OK. (63602)
If you press the ENTER key on the IzoT CT Default Options tab, the displayed options will disappear. Workaround: Either re-select the category or click a different tab in the OpenLNS Design Manager and then re-click the IzoT CT Default Options tab. (41369)
If you use IzoT CT from a different user account than the one used to install the IzoT CT software, the following error message may appear when you initially open or create a network: “Cannot start IzoT CT. If you have run Visio directly, please instead run IzoT CT Design Manager…”. Workaround: Exit Visio, exit and restart the IzoT CT Design Manager, and then re-open (or re-create) the network. If the problem persists, reset the Visio workspaces as described in Corrupted Visio Macro Security Settings. (23900)
In some cases, the bottom edge of the IzoT CT Design Manager dialog may be clipped. Workaround: Go to the IzoT CT Default Options tab, and select the IzoT CT font category. Change the Dialog height factor (for example, if it is 1, change it to 1.1). Close the IzoT CT Design Manager, then restart and repeat the process, restoring the original Dialog height factor value. (64882)
If you import a network created with the LonMaker tool into IzoT CT, the folders in which the drawings and databases are stored may be different. IzoT CT stores the drawings and databases in the C:\Users\Public\Documents\LonWorks\OpenLnsCt folder by default; the LonMaker tool stored the drawings and databases in the C:\LM folder. Workaround: In the General tab of the IzoT CT Design Manager, change the selected folder in the Drawing base path field to select whether the IzoT CT Design Manager lists the IzoT CT networks or the LonMaker networks. (63419)
If you move a reference connection in one IzoT CT client, other IzoT CT clients will not be updated with the new location of the reference shape. Workaround: Replicate the drawing update in all instances of IzoT CT, or use the auto-alignment feature.
If the IzoT Net Server does not have read/write access to the folder containing an IzoT CT database, you may receive an LCA #22 [DB Access Error #-2032] error message when trying to open that database Workaround: Use the Windows File Manager to browse to the folder containing the network database, which is C:\Users\Public\Documents\LonWorks\OpenLnsCt\Databases\<network name> by default, right-click the folder, and select Properties. Click the Security tab, and then add or edit an entry for “Everyone” with Modify permission. (67626)
If you perform a network merge and the source network contains a subsystem (Visio page) with an ampersand character (&) in its name, IzoT CT may report an unexpected error or Visio may fail. Workaround: Remove ampersands from all subsystem names. (51231)
If you back up a network that uses a remote network interface (RNI) and restore it on a different computer, the name of the default network interface for the restored network will be the RNI even if it has not been defined on the current computer (or if the RNI is defined, but references a different device). Workaround: Use the LonWorks Interfaces application in the Control Panel to create an entry for the correct RNI, and then select that RNI when opening the network. (47073)
You cannot use the Accelerator keys to access the IzoT CT menu items in the Visio 2010 Add-Ins tab. Workaround: Use the mouse to access the IzoT CT menus. (57703)
If you recover a network, some of the devices in the top-level subsystem may be recovered to a subsystem named “Subsystem 5”, which is not the top-level subsystem. Workaround: Move the devices and functional blocks from Subsystem 5 to the top-level subsystem as described in Changing the Subsystem for an IzoT CT Shape in the IzoT CT User’s Guide. (41815)
If you open both the IzoT CT help and the IzoT CT Browser and then close the IzoT CT Browser, the IzoT CT help file also closes. Workaround: Do not close the IzoT CT Browser if you want to continue using the IzoT CT help file, or re-open the IzoT CT help after closing the IzoT CT Browser. (39570)
A security warning dialog may be displayed when opening a drawing that includes the LonPoint stencil. Workaround: You can safely close and ignore the warning.
When IzoT CT attempts to register the LonPoint plug-in and the LonPoint resource files are not properly installed, the LonPoint plug-in may display an error message that is hidden behind the Visio window that makes it appear as if IzoT CT has failed. Workaround: Minimize the Visio window to expose the LonPoint plug-in error message, and then click OK. (59536)
The IzoT CT tool and some plug-ins may fail if devices, functional blocks, or network variables have multi-byte character names. Workaround: Change the name of the object in the IzoT CT drawing and then restart the plug-in. If that does not correct the problem, do not use a multi-byte character name. (41701)
