Issue Not receiving any messages or transactions from a single link even though the other links are working. Environment I/NET Seven (any revision) Xenta Server 2.x Cause Xenta Servers of this revision will sometimes lockup if a high volume of IP traffic is received and not send through any events or alarms through to the designated Hosts, even though everything else appears to be operating correctly.  You can locate this issue by viewing the I/NET Command "inet ip" through the Xenta Server web interface.  What you will see is an usually high number of messages in the Msg column (as shown below): Resolution To re-establish AMT from the link, the quickest fix will be to reset the Xenta Server.  This can either be done by a simple power reset or a Warm Start command through the Web Interface, Tools, Commands option.  This will usually get the device up and running. If you are running an old version of software then it is always recommended to have the latest version firmware in the Xenta Servers.  This can be downloaded from The Exchange

Issue A modem is already connected to a remote site's tap. Settings in the modem need to be changed. Can this be done by dialing into the modem in its present configuration? Product Line TAC INET Environment I/NET remote site communicating via dialup modem Cause The remote site's modem needs to be connected to a PC or Laptop. Resolution No, a modem can not be configured by using its present configurations. Windows HyperTerminal is suggested to edit modem settings.  Refer to TCON 226 (Dial Applications) and TCON 101 (Taps and Repeaters). For emulated tap set up, refer to the appropriate Controller TCON. Issue A new SCU 1284 out of the box that you are setting up and it shows up with an * in Netcon. Product Line TAC INET Environment SCU 1284 Netcon Cause SCU's manufactured before 2009:  There is really nothing wrong with the SCU itself, but there may be an Eprom on the board that is not the correct one. It is the one that is used for the SCU 1280. Newer SCU's: This is generally caused by an incorrect setting in the MCU configuration Resolution Verify that you have the correct MCU configuration settings.  An SCU 1284 should be set to DPU.  An SCU 1280 or 1200 should be set to DIO.  Check Network configuration to see if the issue has cleared up. If it has not cleared up try the following: Delete the item from Network Configuration and allow it to repopulate. Ensure that the DIP switch is set to the correct address. Follow the instructions to reset the SCU located in Reset Instructions for 1200 Series SCU.  Then reload the bin file. If you are still having issues then the best option is to send that unit back and have it replaced with another.

Issue Need to add some RTD sensors to a 7716 PCU. I need a P8RTD expansion card. Environment I/NET site Cause  Can I order a P8RTD expansion card? Resolution This expansion card is obsolete. Please refer to the TCON096 for current information on accessories and expansion for the 7716.

Issue Do NPRs use downloadable firmware? Environment I/NET site Cause Do NPRs use downloadable firmware? Resolution Like many I/NET devices, the NPR has downloadable firmware. Refer to Chapter 5, Controller Functions. (TCON209, 2-26)

Issue Monitor the communication integrity of sub-LAN smoke control points Environment sub-LAN controllers Smoke Control Cause Smoke control systems must maintain communication with the sub-LAN controllers at all time. Interruptions in communication must be immediately known and responded to. Resolution Create a single point that will go OLD if communication is lost to any of the smoke control sub-LAN controllers. Refer to TCON 231, Smoke Control Systems, Manual, sub-LAN monitoring for more information.

Issue What is the replacement or repair options for the Model 7728 Series I/SITE I/O Controllers? Product Line TAC INET Environment I/NET site Model 7728 Series I/SITE I/O Controllers Cause Failure or issue with the 7728 controller. Resolution For repair there is a set price one can acquire from the repair department.  For replacement: Order a 7798B Put a CLX card on it Order a 7718 controller for the triac outputs It is complex, but the 7728 was a blend of all of these components.  For the 7728, here is the TCON114 and the Marketing Brochure.

Issue Minimum CFM not maintained when MR-VAV-AX goes into un-occupied mode. Environment I/NET MR-VAV-AX Cause As shown on Page 51 of TCON 147, this is part of the design of the VAV.  Resolution If you must maintain a minimum CFM. Remove any schedules or calculation point extensions that may cause the box to go to unoccupied state. Set the Loc Occ (Local Occupancy) to Occupied and disconnect local occupancy sensor Set the MCI Occ to on As stated in TCON 147 page 51.  When in any un-occupied Mode, Minimum CFM is not used. The system will toggle between 0 CFM and Cooling High Flow depending on box load.  Also note that if Central Plant Heat is not enabled. Then there will be no call for heating when Un-occupied.

Issue May I use the same Name for each NPR in the network? Environment I/NET site Cause May I use the same Name for each NPR in the network? Resolution No. Each NPR must be given a unique name. Spaces, underscores and other symbols may not be used. (TCON 209, 2-27)

Issue What is the recommended maximum size the SQL database can be using MSDE? Environment I/NET Cause What is the maximum size the SQL database using MSDE? Resolution The MSDE server software distributed with I/NET Seven imposes a 2GB restriction on database size. Larger facilities, particularly those using image verification and/or AMT archiving, could potentially encounter data storage problems due to this restriction, and should consider upgrading to SQL Server 2000. Refer to TCON 300.

Issue In XBuilder there is a setting called "Max number of HTTP sessions" that can also be found using the web interface by navigating to Configuration > Servers > HTTP Server. What does this setting do? Does it limit the number of users who can log in simultaneously? Environment Xenta Server Xenta 511, 527, 555, 701, 711, 721, 731, 913 XBuilder Cause This setting is somewhat vague and is sometimes believed to be a limit on the number of simultaneously logged-in users. Resolution The Max. number of HTTP sessions is set to a default value of 15 and can be set to anywhere from 10-20. This setting does not limit the number of simultaneously logged in users, however. The TAC Xenta Server - TAC Networks Technical Manual explains this setting as follows: HTTP The Xenta Server is an HTTP (Hypertext Transfer Protocol) server. Several users can view the web pages at the same time, but they are limited by the number of HTTP sessions allowed. Max. simultaneous HTTP sessions, choose a number from the list. The default setting is 15. Several users can view files at the same time. What is an HTTP Session? Internet Explorer is an HTTP client, sending requests to the Xenta Server. The HTTP server in the Xenta Server receives the request and, following any necessary processing, the requested file is returned. An HTTP session is the connection that exists during data communication between the web browser and the Xenta Server. The session ends when all the data has been received. Rules of Thumb Each web page (values page, alarm page, and the graphics page), sets up a full HTTP session. When loading a web page, a number of sessions may be used simultaneously, depending on the number of sessions available.

Issue Can I place any of the output relays on a 7716 in manual override? Product Line TAC INET Environment I/NET site Cause Manual override for output relays assists in troubleshooting and servicing. Resolution Yes. There are Hand-Off-Auto (HOA) switches for each of the output relays on the 7716. See TCON 096.

Issue Damper position and Valves do not respond to any commands that are sent to it. Environment MR-VAV-AX Cause The SPL setting on the device was set to 1650, this is a default setting but needs to be set to a correct value otherwise  the damper position would not function properly. Resolution The chart below can be found in TCON147: ASC-VAV-AX Installation Guide, page 69. This shows what values need to be set for this to function. Table 12. Shutdown/Purge/Lockout Values S/P/L Value Mode Cooling Damper Heating Damper Auxiliary Heating Fan Heat 0 to 99 Normal Modulating Modulating Cycling/On Cycling 100 to 199 Lockout - Heat Modulating Closed Off Off 200 to 299 Lockout - Cool Closed Modulating Cycling/Off Cycling 300 to 399 Lockout - Full Closed Closed Off Off 400 to 599 Purge CHF CHF On Off 600 and over Shutdown Closed Closed Off Off

Issue MR 160 resets every minute. It is the only sub-LAN controller resetting. Replacing the hardware has no effect on the resetting issue. Environment MR160 Cause Station conflicts can cause this behavior. The MR 160 is unique in that it uses two consecutive addresses on the subLAN and is designed for inputs only. The MR 160 provides no output points or MR-resident DDC modules. Resolution Make sure there are no station address conflicts. Make sure the database has not violated the specifications for inputs only. Refer to TCON 126 for more information.

Issue Limit access options of the users of the I/NET system. How many passwords are allowed? Environment I/NET User administration Cause There are many reasons to limit the access of different users in I/NET. One, for example, is if the HVAC is part on the Smoke Control Strategy.  Resolution The host password scheme covers over 100 individual host/system functions and capabilities. The number of uniquely defined users, when unique passwords for each, is virtually unlimited at the hosts. Refer to TCON 231, Smoke Control Systems Manual, System Access Control, Passwords for more information.

Issue Can the current revision of I/NET Seven Software CD key be used to install older revisions of I/NET Seven Software.  Site has a revision of I/NET installed older than the current release version and additional Site or Seat License is required for the site. Upgrade or revision changes. Product Line TAC INET Environment TAC I/NET Seven Cause Additional License Seats requested by site\customer. Resolution Only current revisions of I/NET seats are available for purchase. Current revision of I/NET Seven Software CD keys are backward compatible within the same major revision release (i.e. 2.40 CD keys are compatible with any 2.XX revision.) Every computer which has I/NET installed must have a I/NET CD regardless if the site is HVAC, Security or both. At a site which has a StandAlone with I/NET, it must have a Site License. If I make that a FileMaster and add one Equalized Client, a SEAT license must be purchased for that Equalized Client. If I add another Equalized Client(s) or perhaps Remote Client(s) additional SEAT licenses must be purchased for those.  The license key is registered to the site, see I/NET CD Key and software revision for more information. When looked up, it reveals how many licenses (Site or Seat) have been purchased for that site. After the initial purchase, any I/NET PC upgrade uses Part Number INETSEVEN24U If upgrading Site computer use Part Number INETSEVEN24U If upgrading File Master use Part Number INETSEVEN24U If upgrading Equalized Client computer use Part Number INETSEVEN24U If upgrading Remote Client computer use Part Number INETSEVEN24U If there is a separate database for a site, let's say they open a new building with INET install with a different db, then an additional Site license is required which would be a new license key. For the latest version information check Software and Firmware compatibility matrix for older versions of the traditional product lines   Upgrade orders can be placed using the following part number: P/N: INETSEVEN24U TAC I/NET Seven Software CD TAC I/NET Seven Getting Started - TCON298 Software License Agreements TAC I/NET Seven Software Box New software orders can be placed using the following part numbers: SEVENMAXR - HVAC & Security site license, w/ CD SEVENHVACR - HVAC only site license, w/ CD SEVENSECR - Security only site license, w/ CD SEVENADDHVAC - Add HVAC, site license only SEVENADDSEC - Add Security, site license only SEVENSEATR - HVAC & Security license for 1 workstation, w/ CD, site license required SEVENSEAT3 - HVAC & Security license for 3 workstations, w/ 3 CDs, site license required SEVENSEAT5 - HVAC & Security license for 5 workstations, w/ 5 CDs, site license required SEVENMANUAL - Manual set, 3 volumes. No CD   Example: The site is currently at I/NET Seven Software Revision 2.14 and requires the purchase of additional seat licenses. The newly purchased seat licenses are the current I/NET Seven Software Revision 2.47. Two options available: 1) Use the newly purchased I/NET Seven Software revision 2.47 seat licenses to install the I/NET Seven Software revision 2.14. Upgrade the sites original licenses from I/NET Seven Software revision 2.14 to 2.47 Older revision I/NET Seven Software can be obtained from either the original CD Media or can be downloaded from EcoBuilding Download Center. Example 2: A site has an existing Host File Master, and Five(5) SEAT licenses(Equalized Client or Remote Client). To upgrade, they would purchase six(6) INETSEVEN24U part numbers which is for each of those workstations. To add an additional I/NET workstation, they would purchase a SEVENSEAT, which is the additional SEAT license.  

Issue Is there a legend for the icons displayed in I/NET Seven? Environment I/NET Site Cause Where is the legend for the icons displayed in I/NET Seven? Resolution Look in the “Getting Started” I/NET Seven TCON298.

Issue Are there any advantages for assigning large key/card numbers directly to individuals rather than using key/card translations tables? Environment I/NET Site define card translation, card number=individual number Cause Client is using same facility code but card numbers are not continuous ranging from 1000 to 4000 and 54000 above. In case the quantity of cards go beyond 32000 is it possible to add these cards to I/NET since each tenant can only take 32000 cards? Having cards with numbers both below 32000 and above, do I have to define card translations for both?. Resolution Large Card support allows you to: Order cards with numbers greater than 32000 Enable individuals to have multiple simultaneous cards during card replacement projects Allows you to replace an individuals card without creating a new individual in the I/NET system INET does support up to 6 million cards but here is the catch. It is 32,000 individuals per tenant, and up to 64,000 individuals per door if you have an SCU or 7920 (with that 48K memory board attached). What this means is each tenant group can be up to 32,000 individuals. You can put cards in, as long as their in the same facility code to make the 32,000 individuals limit. If you define card translation, then you are able to go over the 32000 as far as the card number. 32,000 is the individual number with a standard 26-bit Wiegand card with the max card number is 65,535. So if you do large number the 32,000 individual number could be a card that actually has 65535 as the card number. For Example you have cards 1 through 32,000 but missing 10,001 through 10,999, then you will have to have to define card translation so you can have card numbers greater than 32,000. 32,000 is the total for individuals. But if you are using Card number equals individuals, it will not accept anything over 32000. it will only work if you are using big card numbers.   Go to TCON 300, page 9-5 (INET Seven Technical Reference Guide) for more information.

Issue LED number five on my 7716 flashes constantly what does this mean? Environment I/NET Site Cause LED number five on my 7716 flashes constantly what does this mean? Resolution This indicates it is transmitting data to the HHC port. The unit is design to do this even if the HHC is not connected. Read more about it in TCON096

Issue What is LANMon and how do I use it? Product Line TAC INET Environment I/NET Controller LAN 78010 Model TAP Cause Further analysis is required to establish physical layer (LAN) issues, which may include some of the following: Abnormally large number of LAN Reconfigure messages Controllers going offline individually or in groups and sometimes all together Large numbers of Station Lost/Restore Messages Frequent problems connecting to controllers and data interruption It is strongly recommended that you look at these issues prior to using LANMon.  Refer to I/NET Physical Layer Issues for rectification and recommendations of these Physical Layer Issues. Another form of analysis is to look at your Processor and LAN loading for each of your controller LAN devices.  Refer to I/NET Configuration Status parameters: Processor Loading and LAN Loading (Percentages (%)) for further information on this. Resolution LANMon 3.0 is a utility program used to perform communications capture and analysis functions on the I/NET controller network. The LANMon utility consists of a firmware program which is executed on a 78010 Tap and a .EXE program which is run on a PC. The Tap running the LANMon firmware connects to the RS485 I/NET controller LAN and listens to the communications traffic on the LAN. The Tap receives and translates the communications to a continuous ASCII stream of data which it sends to the LANMon PC using the RS232 channel. Download TCON301 which describes the installation, configuration and operation of LANMon. Click here to download the LANMon application. EPROM is available through either your logistic channels (Australia Only) or alternatively refer to Using the LANMON 3 tool with a 78010 TAP with a MIP01 board attached on how to use a MIP01 to achieve the same function. After capturing your LANMon files, you can then send your captured files to Product Support for further analysis if required or use Decoding LANMON 3 errors to assist in decoding the capture.
