Issue Two different revisions of I/NET 2.31 were created: 2218 and 2227. How do you know which one to use? Environment I/NET 2.31 Cause Inet 2.31 was released with two different builds 2218 and 2227. Resolution The latest build for I/NET 2.31 is the 2227 build. If a site is running the 2218 build, it is recommended to upgrade to the later build since many functions have been greatly improved. Log in to The Exchange Download Center to download I/NET v2.31.

Issue It is not possible to access graphics in a Xenta 5/7xx from a smart phone mobile app. Environment Xenta 511, 527, 711, 731 Smart Phones: Apple iPhone, iPad, Android Cause Graphics in a Xenta 5/7xx webserver render in the web environment using Java.  There is not currently a smart phone in the market that is works with Java applets. Resolution There is currently no supported mobile solution for viewing graphics in a Xenta web server. 

Issue Problem with downloading bin file with more than one door defined causes second set of doors to deny reads. Bin files connected to this issue are 3.24, 3.25, 3.26 Environment TAC I/Net Seven using Access Control. SCU 1284 configured with two doors. (Dip Switch 6 ON gives double address)  Cause Bin file failure to download with double address setting. Resolution On an SCU, an SCU is configured for 4 doors. 2 of those doors are working. 2 of the doors on the SCU are not working. Only thing that has changed is the SCU was downloaded with a new bin file. Nothing in door configuration was changed, no dip switches were altered. Solution: Find out which doors were not working, (probably the second two doors like 0104) Go to Edit/controller/MCU Configuration and Set those doors to Internal, and then download the SCU with the bin file again. Go to Edit/controller/MCU Configuration and Set the doors back to DPU. 

Issue Error message from I/Net Seven controller such as a 7790 in AMT which is "Memory Queue Overflow" or "Memory Overflow." Environment TAC I/NET Seven either direct connect to controller (such as a 7790) or Ethernet connection to a NPR (such as a Xenta 527) Cause Memory overload or bottle neck caused by excessive number of messages through the network. Resolution Memory Queue Overflow or Memory Overflow messages seen in the AMT (Alarms Messages Transactions) window is often caused by an excessive number of messages being requested to transfer through the network device. When you look in AMT you should check to see if the message comes from the Controller (such as a 7790) or from the NPR (such as a Xenta 527).    Throttling back the number of messages by reducing trending data, alarms, transactions, samples, or other information flow will reduce they data and free up some bandwidth.  How many controllers are connected to the NPR? Perhaps you can break this number into smaller allotments and reduce the traffic on the C-LAN which reduces the bandwidth required through the NPR. 

Issue Get message "Could not open or create file.: AC_Xenta_721.cfg" in the Xenta Server error log and in TAC vista event log. The message appears about every 10 seconds. Environment Xenta Server Xenta 511, 527, 701, 711, 721, 731 Cause This is a defect in the software. Resolution This happens if you use the internal online signal e.g. as the input for an alarm. Take out the references to the internal online signal

Issue Why do you need to mask the events in both door editor and the point itself (08, 09)? Environment I/NET Seven Cause Door masking is required in both the door editor and the point itself. Resolution Think about door masking as layers. When you create a door, you need to create a point/relay for the door. This relay changes state (0,1), this is the hardware layer, Layer one. In order for AMT to get a event that the point have changed state it needs to ask the controller of the status. This is done by a quick poll command issued by the SLI. In order to make this point to behave like a door we need to add some feature to it, a second layer. This layer is not hardware dependent but it speaks to the hardware. Here you can add some additional event or in this case alarm as "forced door". This alarm will be distributed to the event handler of the point so next quick pull will catch this information and it will be sent to AMT. So in order to get alarms and transaction from the door specific attributes both the point/relay (So the quick pull can get its information) and the second layer door needs to be masked. So the information will become correct its also important that the points and door masking priority are the same.  

Issue Filemaster is Full SQL 2005 and Equalized Client is SQL Express fails to equalize.  Environment 2.31 version of TAC I/NET Seven 2.4x  version of TAC I/NET Seven Full SQL 2005 for the Filemaster SQL Express for the Equalized Client In the test environment, the Filemaster and Equalized Client has Windows XP, Windows Vista, Windows 7 for operating system. Cause SQL Express  doesn't start equalization services automatically. Resolution The Equalized Client refused to replicate the database with the Filemaster. Equalization is not succeeding even though the little icon may say it is equalized. Filemaster shows pending. Start I/NET and check the host passwords to see if equalization has taken place. The following steps will cause equalization to take place:  Restart the pc to ensure there isn't a program hanging in the memory. Demote Equalized Client to Stand Alone. Exit I/NET and I/O Server Go to Start/Run/CMD Maneuver to the c:\Program Files\Inet Seven folder and type the following:  ineteqzmerge /unregserver     press the Enter key ineteqzmerge /service     press the Enter key Now go to Services by selecting My Computer/Manage/Services and look for the Service running called InetEQZMerge and start the service and select Automatic. Now you should promote the I/NET workstation to Equalized Client ensuring you put the Filemaster Name rather than IP address. The snapshot will be delivered to the Equalized Client. After equalization you may need to shut down I/Net and the I/O Server one last time and then restart I/Net Seven. Now return to Services by selecting My Computer/Manage/Services and look for the Service running called InetEQZMerge where you should STOP then START the service again.  One way to test equalization from Filemaster to Equalized Client: in I/Net Seven under Edit/Host Computer/Passwords add a user/password. Check the other computer to see if the database replicated the new user/password and Vice Versa. If ineteqzmerge is already running as a service.  Try stopping and starting the service. Note: Using SQL 2008 on a Windows Server 2003 OS? Read TCON301 on page 2-4.

Issue Under user admin in a Xenta server you can change the content of the 3 frames that the user sees when logging in. If the user have changed the default frames for the root user in a Xenta server so that the tree navigation is not available you can't navigate back to user admin to reset the frames. Environment TAC Xenta Server Xenta 511, 527, 555, 701, 711, 721, 731, 913 Cause User have changed the frames so that the menu tree is no longer available Resolution Log on to the Xenta server with the root account. Type in https://xx.xx.xx.xx/wm/useradmin/ in the IE address field. This takes you directly to the useradmin page. Click on the root user. Under Frame Settings click on Use Default for the Menu frame.

Issue Is the ICI editor and associated BIN files still available. Environment I/Net Seven all revisions. 7797 ICI all firmware revisions connecting to a third party device.  Cause It is not clearly defined in the documentation the location of the ICI Editor and associate BIN files. Resolution The ICI Editor is part of the I/NET install CD, the application is found under the folder name ICI-CD.  The associated BIN files for these devices are also located on the I/NET CD under the folder name SUPPORT\BINS.

Issue TCP/IP Network Settings required for an I/NET Seven Installation.  If the incorrect network speed is used, communication with the NPR-2000 and the Xenta 527 will fail. Environment TCP/IP Network I/NET Seven NPR-2000, Xenta 527 Cause I/NET works on 10 Mb/Second (also known as 10-half).  The NPR-2000s and the Xenta 527 will only function on 10-half. Resolution I/NET requires Microsoft's TCP/IP protocol. While I/NET Seven can coexist with another vendors networking software, (Novell or Banyan, for example) it will not use any other version of TCP/IP. You can add Microsoft's TCP/IP in the Network options of the Control Panel. Most modern Ethernet Switch gear should be set to "Auto Negotiate" for 10/100mb speed required by a device, but speed is an important factor for proper communication.  I/NET can only run on a 10 Mb/Second network. Old style NetPlus Routers(NPR-2000), Xenta  527 NPR, and Xenta 527 Web require 10 Mb/Second.  See TCON 300 (from the Technical Reference Manual included on the I/NET installation CD) for further details.  TCON 300 has all of this information on pages 1-9; 1-33 & 1-34 Because this is not an individual PC configuration, assistance from the building IT staff will likely be required.  

Issue Change of font color isn't kept when viewing graphics page. Environment TAC I/Net Seven by Schneider Electric Cause Font colors not remembered when selected, for example on an AI point, simple temperature value, the font at the bottom of the screen is changed to any of the colors available. I/NET reverts back to black. Resolution Located on the I/Net Seven 2.31 cd, there is a folder named: Patch-B Graphics Paste Inside this folder is a file named: INET Rev 231Graphic Patch with size.zip  Take this file, unzip, and with INET closed, and the I/O Server shut down, copy into your I/Net Seven folder on the C:\Program Files\INET Seven This overwrites a variety of files, dll etc. 

Issue How to allocate a range for individuals on an I/NET system. Environment I/NET Seven  Cause Individual Needs to be added to I/NET Seven Resolution Select the Individuals tab from Access/Individuals and choose the Tenant that the individuals are being added to. On the bottom of the editor is a button called Allocate Range, select this and when the editor comes up and put the number that you want to start from as well as the number of individuals that is being added and click on the Okay button. The Individuals will be added immediately to the system and they you can make necessary changes to each as deemed fit.

Issue In I/NET version 2.16 and above, after installation, the first thing that needs to be set up is a profile. It can be a new one or use the existing one profile. Environment In I/NET version 2.16 and above, after installation, the firs thing that needs to be set up is a profile. It can be a new one or use the existing one profile. Cause In I/NET version 2.16 and above, after installation, the first thing that needs to be set up is a profile. It can be a new one or use the existing one profile. Resolution Start the I/O Configuration, log in using the default username and password. Select the default settings and once the editor opens up, choose the link set up that will be used for this configuration, like Direct Connect, Com number, Baud Rate.  For Direct Connect the Hardware address must be 0. In the Workstation Options, click on the connect button and verify that the correct Database is being connected to. For a Server/Client Option, verify that the local host is set to Remote Client if using a different database that resides elsewhere (this is only for versions 2.40 and higher). Enable Access Control and CCTV if this is being used or leave unchecked if not. Leave the default save directories, unless you plan on saving elsewhere. Enable TCP/IP if needed and Host number. Put in reference Hosts if applicable, set I/O Server to Shut down if no clients or Maintain, depending on what you want it to do. Click on the okay button, to close the editor and click on Make Active to enable the new editor to be the active profile. Close I/NET and I/O Server and then restart it again. The new profile should be active and running now after the correct user name and password has been entered.

Issue Unable to add points or trends to a 7793 Controller, even after changing the address and redownloading the bin files to it. Applies to 7793, 7716, 7728, 7756 Environment Working on I/Net Seven system. Cause Unable to add points to controller. Resolution Using a HHC (Hand Held Console) plug it into the Com port on the board Select CTRL MEM 0 ENTR, 0 ENTR Hit the Red Reset button and clear the memory of the board. Go to Edit Host Computer, Network Configuration Penetrate the Link Summary, the device will show in the boot state Save it and then close out of this editor. Go to Edit Software Restore Select the device and download the bin file and sav file back to the controller again.

Issue What does it mean when a point goes "OLD" in I/NET? Product Line TAC INET Environment I/NET Cause Points are labeled as old when the value is invalid or the point is no longer communicating. Here are possible reasons a point shows up as "OLD" or "old data" The SubLAN or UC device is offline or not communicating. In this case all points on the device will show as "old data" Indirect points are flagged as "Old" anytime an update request is initiated and no response is received from the global point for 2 scan intervals. If the sensor on an input produces a number either lower than the low sensor limit or higher than the high sensor limit the point will go old. DDC control logic outputs a value out of range of the point SubLan Communication error Improper global level on sending controller Resolution The SubLAN or UC device is offline or not communicating. In this case all points on the device will show as "old data" Check to ensure the device is powered up and check physical communication. Ensure that the device is enabled in MCU Configuration and verify that the correct device type is specified. Indirect points are flagged as "Old" anytime an update request is initiated and no response is received from the global point for 2 scan intervals. Check the scan intervals of the indirect point and increase it to a larger setting. See TCON300 for details about how information requests are send between global and indirect points. A long scan interval will not translate to a delay in information being sent. Also check the communication path between the 2 points and ensure all equipment is working properly. For example if there is a known issue with an NPR that has global points underneath it, then all indirect points referencing those global points will frequently go old. If the sensor on an input produces a number either lower than the low sensor limit or higher than the high sensor limit the point will go old. Check the sensor and determine if it is faulty. If the value that is being sent is acceptable then increase and decrease the High and Low Sensor limits. This can also be caused by a sensor being disconnected. DDC control logic outputs a value out of range of the point Check all points that the DDC references and determine which is going old. Use Failsafe commands whenever available. SubLan Communication error Check the physical condition of the wiring on the SubLan. Determine if any SubLan device is faulty and interrupting communication. Improper global level on sending point Connect to the controller with the sending point and check it's global level. if the receiving point is on the same physical controller LAN wire you can set this to "LAN". If not, set it to "System"

Issue Do you have an issue with an MR-VAV where it is resetting itself every so often and in the Messages Window of AMT, an MCU Lost, and MCU Restore message is displayed for this address? Environment I/NET Seven Cause The main cause for this is power or grounding to the device, indicative of the messages in AMT. Resolution Verify that the power supply (XFMR) is correct and outputting the correct voltage to the device Verify that the device is grounded properly, with no strands of stray wire touching anywhere. Verify that the communication wires are terminated properly and free of interference. Clear all stats on the MCU Configuration/Station and verify that no bad CDRs are coming up again after all the above steps have been completed.

Issue Unable to link External Point to a global point Environment I/NET Cause Global points can only be linked to indirect points Resolution Create an indirect point on the same controller as the external point you wish to reference.  Configure that point as an Indirect point and enter the I/NET address of the Global point.  Add a calculation to the external point that makes it equal to the Indirect point. Ensure that your Global point has the correct global setting.  Refer to TCON 300, I/NET Seven Technical Reference Guide, page 6-10 for more information.

Issue Unable to set up a TTS100 Sensor on an MR88. Environment I/NET Controller with MR88 Sublan devices. Cause Hooking up a sensor on an MR88 and it is not reading the correct temperature on the Summary page. Resolution Verify that there is a 10K Ohm Resistor in the B Slot of the MR for the required point. Using an m=0.018 and b=-148, with counts of 0-255, since it is an 8 bit converter and Lookup Table #2 if it is on one of the Universal Inputs, or Lookup Table #1 if wired to the I/Stat port. It is connected to Red=Signal and Green=Ground.

Issue During the boot sequence of a Xenta Server the message "Unmap block xxx at remount" occurs. Environment Xenta 511 Xenta 527 Xenta 555 Xenta 701 Xenta 711 Xenta 721 Xenta 731 Xenta 913 Cause Sections of the flash drive are being declared bad and are being removed from the accessible drive map. This can be a natural pruning process of bad sections due to drive damage or that section exceeding the maximum number of writes. The amount of lost space is: # of pages * 2 bytes All hardware 2 Xenta Servers have 16mb flash drives, so it takes a large number of pages to be lost before significant space is lost and will impact performance of the unit. Resolution If the number of pages is low and is not increasing then the unit should function normally without any additional action. If the number of pages is exceeding 50000 or increasing rapidly, then have the Xenta Server repaired or replaced depending on its age.
