Issue TAC License server can't be started. TAC license server crashes Environment TAC Vista 5.1.8 Cause The license server can't start if there is a DEMO license in the same folder as the "real" license. Note that in 5.1.8 the default path to the license files have changed to: C:\Program Files\Schneider Electric\License Server\TacLic\Licenses Any license files that are in the old directory will be moved to the new one when upgrading. If you need to use DEMO licenses for a site you can add them to a separate directory and add that directory in the license setup.   Resolution Delete any DEMO licenses in: C:\Program Files\Schneider Electric\License Server\TacLic\Licenses Go to services and start TACLicenseServer

Issue Unable to update an ASC when adding a new MR to an existing system. Product Line TAC INET Environment All versions of I/Net utilizing HVAC applications. Cause On a system that has multiple sublan devices and adding a new or several devices to the controller, when updating the UPD files it appears to get downloaded but when the MCI update is done, only one point is written to the database. If the points are added manually, a Memory Error would come up indicating that there is not enough memory in the controller to do this. However, this is not seen when doing the UPD file update nor MCI Update. Resolution To resolve this issue, the following steps needs to be done: Connect to the controller Go to Edit/Controller/Configuration Verify that the controller does in fact have memory left If not, look at the trends that are on the resident I/O Points If possible, delete unwanted trends that are using up memory to free it up to allow these devices to be added Once done, go back to ASC Parameters and then update the ASC and MCI again.

Issue Filtering The AnalogSamples_xi.rpt SevenReport using the cell definition Environment I/NET Seven Reports Cause In some cases, the cell number can be used on a 7 trend to allow only trends of a certain type to show up in reports.

Resolution To make sure you are using the correct Kvs value, please refer to the latest available documentation that is available on the Extranet.

Issue The BDelay object from the LonWorks jar conversion library intermittently shows very large "remaining time" causing logic issues. Environment R2, UNC's Cause The BDelay object does not initialize the time remaining properly under some conditions. Resolution In the Lib jar - programObjects - hvac folder there is a program called DelayedOutput.sns.  This program can do the delayed on and off function but will need to be enhanced if the time remaining output is required.

Warning Electrostatic Discharge Required: Always discharge static electricity from your person by touching metal prior to handling any hardware. Failure to do so may result in damage to devices. Issue How should the Micro Energy Power Supply voltage reading be checked? Can the Micro Energy Power Supply provide power to IOU only without CIU connected? Environment Infinity SX8000 Cause Got the Micro Energy Power Supply repaired by 3rd party but the voltage reading seems to be incorrect. Resolution The voltage of the Micro Energy Power Supply should be checked with the load connected to the PS.   For the port_A voltage check, have the CIU connected to the port_A of the PS.   For the port_B voltage check, have the IOU connected to the port_B of the PS. Also the Micro Energy Power Supply can have either the port_A connected to CIU only or the port_B connected to IOU only or both ports connected to CIU and IOU respectively. For detail information of the voltage reading of each pin, please refer to page 2-86 ~ 2-88 of the AC256 Service Manual.pdf
