Issue What are termination (end of line) resistors and why use them? A LAN of any type has a node or two somewhere in the middle having problems but the rest seem stable Product Line TAC INET Environment I/NET Site Controller LAN 7808 Repeater Cause Termination resistors (also called clamping or end-of line resistors) are to be installed between lan+ and lan -, not to ground. Their purpose is to prevent the characteristic impedance of the wire from increasing to infinity at the end of the cable. Resolution Since most wire's characteristic impedance is between 80 and 150 ohms, use 100 to 120 ohms on an unbiased controller or host lan. This will "clamp" reflections from the end of the wire which are seen as noise by the controllers. If a 7808 repeater is used, it requires bias. Using 100 ohm termination resistors would kill that lan's communication; therefore, use 620 ohms instead. As cheap as resistors are and as easy as this installation is, they can only help. Typically they help more on a longer LAN, so anything longer than 1000 feet (about 300 meters) should definitely have terminations.

Issue Error in Xenta 527 HyperTerminal     This happens over and over (with different file sizes each time) and the controller essentially is locked up. Restart is required. Product Line TAC Vista TAC INET Environment TAC Vista  <5.15 Xenta 527 to RS-485 I/NET Cause Vista will poll I/NET for the past 1000 entries at a time. Normal internal events consist of a lot less data than the I/NET events, So 1000 I/NET events in one message makes the message to large. VSD Response too large error indicates Xentas max message size has been reached. Vista ignores the error and continues to try again and again. So the Xenta 527 essentially is stuck in a loop. Resolution Polling I/NET for less events fixes this problem. The max number of events in one message has been adjusted down to 400. This change is included in TAC Vista revisions 5.1.5 HotFix 16 and later.

Issue Triggering a default value to internal AO points when the value is reset to 0 Product Line TAC INET Environment I/NET Seven Event Sequence 0 Cause #A controller will run Event Sequence 0 any time one of these changes occurs: Power up Controller reset Database restore Internal AO point values will default to 0 (zero). If this AO point is used as a setpoint in a DDC loop, this could cause issues. Resolution Option 1 Use Event Sequence 0 to set internal setpoint values to a default value following power loss, reset, or restore. When connected to the controller, navigate to Edit > Controller > Event Sequences Click on Seq 0 and choose "Add." Sequence 0 is reserved to run on reset. Add an action Action: Output (or Output with lock) Delay: Defaults to 0 Point: AO that is used for the setpoint Skip/Value: Desired default setpoint value. Below is an example of what an Event Sequence 0 looks like of an Internal AO used as a setpoint. In this example anytime Event Sequence 0 runs, it will output a value of  75 degrees. Option 2 Open up Event Sequences. Add event 0 to the list. Event sequence number 0 runs at a power up, after a reset of controller power or a database restore of the DCU. Modify event sequence 0. Put every interanal "AO" setpoint in this event with a default value that is safe to operate at.

Issue Software installation problems with Windows 7 OS and above Configuration problems also known as UAC / User Account Control These problems occur when you receive an error message stating that you do not have the correct administrative rights to continue. Product Line Andover Continuum, EcoStruxure Building Expert, EcoStruxure Building Operation, Satchwell MicroNet, Satchwell Sigma, TAC INET, TAC Vista Environment Windows 7 Windows 8 8.1 Windows 10 Server 2012 Cause Windows 7 and above user administrator privilege settings (UAC) Resolution The solution to this issue is to turn off the user admin settings before the software is installed by following these instructions: Go to Start > Control Panel. Set the view to "small icons" to show all Control Panel icons Click on "User Accounts." Make sure that the account used for installing the software is a full admin user. On this page, click on "Change User Account Control settings", a slider bar that starts with "Never notify" up to "Always notify" by default will be set to "Notify me only when programs try to make changes to my computer" Set it to "Never notify." This will disable all the admin blocks that pop up in installing and configuring software Once set, restart the PC and then continue with your software installation and configuration Once all is installed and working, the feature may be turned back on if required. Additional requirements for Windows server 2012 and Windows 10. Please note: this process may open the "Windows 10 Firewall up" For Windows Server 2012 and Windows 10, additional steps are required to disable User Account Control. Although the slider bar can be set to “Never Notify”, the User Account Control does not disable completely. The User Account Control can be disabled for any user by setting the system registry value “EnableLUA” to zero in the system registry under the registry key “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system”. A Windows registration file has been included in the Continuum 2.01 release in order to expedite these additional steps. Or the attached file EnableLUA.zip can be used, unzip and execute.  Supplement: Using the right click "run as administrator" instead of this is not the same. The right click will only run that .exe as an administrator and not the whole install/configuration package, i.e. SQL2005 manager will fail to run if you do not do as instructed above. You will always get an error stating that you do not have permission to run this program.  Alternate Windows 10 Admin. to User privilege for I/Net Seven:   Go to this path: C:\Program Files (x86)\ Inet Seven 1) Rename and move to a new folder these files.       A) INetIoSrv.exe.manifest       B) INetW.exe.manifest       C) If there is a file equalization client, then there is INetEqzMerge.exe.manifest to do this change on as well.  2) Change the DbCreate by doing this:       Another problem for non-admin users will be logging into and using DbCreate. A work-around for that would be to create a new login into the SQL database that could be shared among all DbCreate users and would provide the necessary rights.       Alternate Windows 7 Admin to User privilege for I/Net Seven:  See the attached Document and Manifest Files

Issue When points show Old Data some processes may cause equipment to shut down. Product Line TAC INET Environment I/NET Cause When a value is out of range in I/NET, any control referencing it will also be out of range.  For systems with communications issues this can be a problem for indirect points such as Outside Air Temp. DDC modules contain a Failsafe Output Control Point which can also over come this obstacle. Resolution Refer to What does it mean when a point goes "OLD" in I/NET? with information on how to prevent points from going "Old".  If the point continues to go old you can use this process to account for the old point: For this example assume that you are monitoring OAT with an indirect point Connect to the controller with the indirect point that is going old. (OAT) Create a duplicate of this point that is internal.  Call it "OAT_mirror" ensure that it has a relatively short scan interval Add a Calculation to OAT_mirror Use this expression: AV(P0,P1)   Set P0 as OAT Set P1 as OAT_mirror Click okay Change any control logic referencing OAT so that it references OAT_mirror Results: The AVG calc function will ignore any old value.  This means that while the OAT point is valid the OAT_mirror will quickly change to equal to it. When the OAT point goes old the OAT_mirror point will retain it's current value until the OAT point is no longer old. For information about triggering an alarm when a point goes old, view Triggering an alarm or message if a point goes old in I/NET For further Indirect Point "Old Data" Filtering Techniques read I/NET Indirect Point "Old Data" Filtering Techniques

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 Cannot see an NPR across a wide area network (WAN) Product Line TAC INET Environment NetPlus Router (NPR) Wide Area Network (WAN) Cause There are several reasons why this may occur: The Cisco/3Com/etc. routers are doing network address translation (NAT) The network uses Variable Length Subnet Masking (VLSM) and the routers use Classless Inter-Domain Routing (CIDR). See the other FAQ on this.  The correct reference host is not specified in the configuration profile. The correct reference host is specified, but that profile was not set to active. The wrong subnet mask was used. Resolution For issues with VLSM and CIDR (Cause 2 above), see Can NPR 2000s be installed on a network that implements VLSM and CIDR. In any other case, see Customer Advisory 2003.
