Issue After doing a "Find new BACnet" devices (or device discovery) none of the BACnet IP X Driver points can be found. Environment BACnet IP X-Driver As used in ACX5740, ACX5720, NC2 (Netcontroller II) to map data between Continuum points and BACnet. Cause The X Driver has 2 modes of operation: Client mode or Server mode, points can only be viewed externally in Server mode. Resolution When using the BACnet IP XDriver you must always first create a Device Self object point as a type 200, this will define the parameters for the BACnet device itself. This allows the device itself to be found in the BACnet view of any BACnet Operator Workstation.   For points with type 0 (BACnet Client), these are not seen in the BACnet view as they are Continuum points that have the BACnet data mapped into them for use within Continuum. For points to be seen in the BACnet view they have to be Type 1 or 2 in a BACnet Server mode.

Environment 1st Generation Controllers CMX 9924 CX 9900, 9901, 9940 Cause Proper controller commissioning procedure was not followed. Resolution When commissioning a first generation network controller, the controller must be rebooted (power shut off and then power restored) once the changes have been made to the controller configuration via a PC using a terminal emulation application.

Issue How many time schedules (time objects, TSCH, TSCHI) can be added to TAC Xenta programmable devices? Environment TAC Xenta 301, 302, 401, 281, 282, 283 TAC Xenta 527, 511, 711, 721, 731, 701 Menta Cause The limits for schedules are not clearly documented for all types of TAC Xenta controllers. Resolution The TAC Xenta 7xx can handle 50 time objects with 50 week and 50 holiday schedules in each. The limit for the TAC Xenta 28x controllers are one TSCH block with max 16 week/holiday charts. There is no fixed limit of TSCH blocks you can add to a TAC Xenta 30x/40x. The limit is the available memory in the controller. The more times you allow for (max. week/holiday charts) in each block, the more memory it uses.

Issue Unable to load the localhost despite having tried all the user names and passwords associated with the PC. Is there way to figure out what user name and password that it is looking for? Or another way to get this to work? Environment I/A Series R2 UNC I/A Series WorkPlace Pro / Admin Tool Cause To log into the LocalHost via the I/A Series R2 Admin Tool, you need to use a username and password that is defined in the local Administrator's group of the computer on which the software is being used. Many times, the user accounts on a computer will be Domain based accounts rather than local accounts.  The I/A Series R2 software cannot authenticate with Domain based accounts. Resolution If you are logged into the computer as a user that is a member of the Administrator's group, you should be able to create a new user account and assign that user to the Administrator's group.  If Windows Domain policy prevents an Administrative user from creating a new local user account and assigning that user to the local Administrator's group, please contact your IT department for assistance. Here is a step by step procedure for creating a new local user and placing that user in the local Administrator's group. Right-click on the "My Computer" icon and select Manage. Click on the [+] box in front of "Local Users and Groups". Click on "Users". Right-Click in the righthand window and select "New User".  A New User window will open. In the New User window, enter IAAdmin in the User name field. In the Full Name field enter "IA Admin" In the Description field enter "Local Administrator for I/A Series R2" In the Password field enter P@ssword In the Confirm Password field enter P@ssword Uncheck the "User must change password at next login" option Check the "User cannot change password" option Check the "Password never expires" option Click the [Create] button then click [Close] to close the "New User" window. In the righthand window, right-click on the user IAAdmin and select Properties. In the IAAdmin Properties window that just opened, click the "Member of" tab. Click the [Add] button In the "Enter the object names to select" box, type in Administrators and press Enter. Click the [OK] button to save the changes. Close the Computer Management window. When you open the Admin Tool and attempt to log into Localhost, enter IAAdmin for the user name and enter P@ssword for the password.
