Issue Poor communications, communications failure or packet being corrupted Product Line Andover Continuum,EcoStruxure Building Expert,EcoStruxure Building Operation,Satchwell MicroNet,Satchwell Sigma,TAC INET,TAC Vista Environment Communications networks, BACnet MSTP, LON FT10, Infinet, Modbus RTU, Ethernet EMC (Electromagnetic compatibility) VSD Variable Speed Drive, VFD Variable Frequency Drive, Inverter Drive Cause Electrical Interference from Inverter (variable speed drives or VSD) Radiated or Induced RFI (Radio Frequency Interference) Resolution A VSD has the potential to create a large amount of electrical noise, to avoid causing issues it is vital they are installed as the manufacturer's instructions. (Other devices also have this potential) Our systems are often used to control VSDs on fan motors, so if poor communications is found during the commissioning process, then try stopping all the fans in the area then re-testing the communications. A recent example was seen where LON FT10 communication was working ok until some VSDs were started, at this point LON devices and Object went offline intermittently. When all the VSDs were stopped the communication become completely stable. It was then possible to find which VSD was causing the problem and correct the VSD installation. In this case a LON analyzer would also have helped diagnose the issue.

Issue A controller or controllers don't communicate reliably on an I/NET LAN, often somewhere in the middle of the network. Product Line TAC INET Environment I/NET Site Cause As the signal travels down the cable it is affected the "characteristic impedance" at a relatively constant amount. As the signal approaches the end of the network, that impedance increases to completely "open" at the end. According to Ohms law, the higher the resistance/impedance, the higher the voltage will be as the current is applied. Therefore the signal will gain enough energy to be reflected back up the cable as noise. The controller(s) that is (are) most affected are located at the point where the reflection from the end of the network arrive during the original signal. Resolution Placing a 120 - 180 OHM 1/2 Watt Resistor at both the physical ends of the Controller LAN will clamp those reflections since the resistor is fairly close to the characteristic impedance of most cables. The Sub-LAN works differently than the Controller LAN, so DO NOT use a 120 - 180 OHM resistor on the Sub-LAN. Instead, use a 620 OHM resistor placed at both physical ends of the Sub-LAN. The reason for this is that if you use a 120 - 180 OHM resistor at each end of the Sub-LAN wiring, you remove the bias needed by the "Mark-Space" signal on the Sub-LAN. The 620 OHM resistor is large enough to absorb some of the noise without messing with the Comm. However, you might notice a slight decrease in signal strength. Also, refer to the article I/NET Controller LAN (C-LAN) Requirements for additional details.

Issue What are the cable requirements? What is the maximum wire length? When do I add a repeater? What is the maximum number of repeaters allowed? Product Line TAC INET Environment I/NET Controller LAN, C-LAN Cause Incorrectly run controller LAN wire can cause communication issues between I/NET controllers and hosts. Resolution C-LAN should be run using: Two wire, twisted pair, shielded cable 24 AWG (0.206 mm2) or larger 30 pF/ft. or less between conductors 55 pF/ft. or less conductor to shield 80 - 150 ohm impedance The maximum controller LAN length is 25,000 feet (7,620 meters) assuming 4 repeaters are used. A repeater should be installed: To segment every 32 controllers Or if the LAN length exceeds 5,000 feet (1,524 meters). The maximum number of repeaters allowed is 4.

Issue Direct Connect to Xenta 527-NPR Product Line TAC INET Environment I/NET Xenta 527 Xenta 527-NPR Cause Newer versions of Xenta 527-NPR with 5.1.0 and 5.1.1 revisions are unable to be directly connected to the system. Resolution Using the FTP connection through IE (Internet Explorer) to connect to the device. Log on using the root username and password Now go to sys/system/hwconfig.cfg Copy out the hwconfig.cfg file and open it with Notepad Modify the part that says serial_A_function="7" and change it to "5" Save this and now copy it back in again. Restart the device Start I/NET and the direct connect through the NPR to the system should be working now. Warning: Reloading the system program (such as performing upgrades) will remove this change.

Issue You are transitioning an I/NET security system to Security Expert The I/NET subLAN must be moved from a 779x controller over to an SP-C Product Line Security Expert, TAC INET Environment I/NET Controller (779x) Security Expert Controller (SP-C) Cause As you transition an I/NET system to Security Expert, you will reach a point where you are ready to start moving your I/NET subLANs over to SP-Cs. Resolution Use the following instructions to connect an I/NET subLAN cable to a Security Expert SP-C. At the I/NET 779x controller, disconnect the subLAN cable. At an SP-C, connect the subLAN cable as follows: Attach the positive (+) wire to Reader Port 1 pin "D0". Attach the negative (-) wire to Reader Port 1 pin "D1". If you wish to establish a closed-loop subLAN configuration, connect the other end of the subLAN wires to SP-C Reader Port 2 in exactly that same manner as you did at Reader Port 1.

Issue Can the I/NET SCU controller connect to Security Expert SP-C directly instead of being imported from the I/NET system? Product Line Security Expert,TAC INET Environment I/NET SCU 1284 Security Expert Controller Security Expert Cause Required to use New I/NET SCU1284 controllers on a Security Expert site. Resolution It is not possible to configure and commission SCU1284 door controllers without the use I/NET on Security Expert. Explanation of why this is not possible: In I/NET, door controllers i.e SCU1284 are on a subLAN that connects to a 779x host device. In the 779x host device, controller parameters such as its reader type, PIN functionality, LED operation, etc are configured for each door. The configuration parameters for each door controller gets stored in the 779x host device, then the host device’s data is saved to a SAV file (i.e., a backup file of the 779x device). To integrate I/NET door controllers with Security Expert, The subLAN (779x host device ) is then disconnected from the door controllers and connected to an SP-C (the SP-C replaces the 779x host device). The 7798x host device’s SAV file is then downloaded to the SP-C as a binary blob. The SP-C needs this SAV file to know how to communicate with each door controller and to configure these devices if a cold restart is ever experienced.

Issue A message that can be intercepted by a guard at a monitoring station. When you configure your access control system to accept PINs, I/NET has the ability to detect PIN entries When you configure your access control system to accept PINs, I/NET has the ability to detect PIN entries made under duress conditions. For example, if an employee is being forced to provide an unauthorized individual access into a secure area, the employee can substitute the final digit of their PIN with a digit that indicates a duress condition. In this case, I/NET will allow access but will also silently generate a duress message that can be intercepted by a guard at a monitoring station. Product Line TAC INET Environment TAC I/NET Seven with Access Control using a pin pad. Cause Duress entrance causes a security guard to be notified that there is a situation to be resolved. Resolution Duress detection is active anytime a door is operating in a mode that requires the entry of a PIN. I/NET supports selectable duress schemes that you can assign on a per-tenant basis. The following duress schemes are available: Default — I/NET's default duress scheme detects when an individual substitutes their PIN with a substitute number. The default duress last pin is 9. The duress code is the user's PIN number with the last digit changed. For example, 12345 becomes 12349. Add n (where n is a value from 1 to 9) — I/NET detects when an individual substitutes a digit of their PIN with a predetermined digit. For more information on this sensitive topic, contact Product Support to begin a conversation about Duress Notification in I/NET.

Issue When printing a graphic page using the CTRL P feature, the page prints but then the page links stop working. Product Line TAC INET Environment I/NET site with Graphics Pages Cause Printing out a graphic page causes the page links to no longer work. Resolution Press Ctrl+P and allow the page to print Right click once on the page marker Double left click on the Page Marker again. It should now work.

Issue Can a 7798C be used in an I/NET 2000 System? Product Line TAC INET Environment I/NET 2000 I/NET Seven rev 1.16 and above 7798C SLI Cause AMT is different in I/NET 2000 than it is in I/NET Seven and any message and transaction from this SLI will not report correctly. Resolution This SLI cannot be used in I/NET 2000. Even if 7798C Bin files are loaded into I/NET 2000, the SLI will not work. This SLI is designed to ONLY operate correctly in I/NET Seven Rev 1.16 and above.

Issue Since the NPR supports Telnet and SNMP, can someone dial into the modem and gain access to a user's network? Product Line TAC INET Environment I/NET site Cause Cybersecurity of the network is important, and any vulnerabilities should be identified and mitigated. IT professionals may ask about the Telnet and SNMP capabilities of an NPR and whether that represents a risk. Resolution The NPR cannot initiate a Telnet session, therefore it will only respond to Telnet prompts. It cannot create an outgoing Telnet session into the local LAN. It is also very limited in SNMP. It will respond to a query with a packet of information. That is all it can do. It does not conduct two-way or bi-directional communication. Hackers can not use these modes to "leapfrog" into a local LAN.

Issue The Xenta 913 supports several different BACnet object types but does not support all object types. Product Line TAC INET, TAC Vista Environment Xenta 913 BACnet Vista I/NET Cause The Xenta 913 is only a gateway device and is not native BACnet and thus does not support all BACnet object types. Resolution The BACnet specification outlines 49 different object types. Objects include physical points, processes and even internal operations. Most BACnet devices, including BACnet certified devices, do not support all of the object types since some of the object types are particular to specific industries and several are not commonly used. The Xenta 913 controller supports the following object types: Analog Input Analog Output Analog Value Binary Input Binary Output Binary Value Multi-state Input Multi-state Output Multi-state Value The following BACnet object types are unsupported by the Xenta 913: Access Credential Access Door Access Point Access Rights Access User Access Zone Accumulator Averaging Bit String Value Calendar Character String Value Command Credential Data Input Date Pattern Value Date Value Date Time Pattern Value Date Time Value Device Event Enrollment Event Log File Global Group Group Integer Value Large Analog Value Life Safety Point Life Safety Zone Load Control Loop Network Security Notification Class Octet String Value Positive Integer Value Program Pulse Converter Schedule Structured-View Time Pattern Value Time Value Trend Log Trend Log Multiple Note that there is some confusion among object types. For example, while it is possible to have a Life Safety point that is a binary output, this is not the same thing as the standard Binary Output object type and the two points are not interoperable.

Issue When I/NET interacts with Endura/Digital Sentry, the Video Window can't pop up when swiping a card or an alarm happens. Product Line Pelco, TAC INET Environment I/NET Endura Digital Sentry Cause The Video Window only pops up in Alarm Window, not in Event or Transaction Window. Resolution For card entry, the Video Window needs to be popped up manually by right clicking in the Transaction or Event Window and choose Video. For alarms, the Video Window only pops up in Alarm Window when alarm is active. After the alarm returns to normal or is acknowledged, the video needs to be shown in Event Window.

Issue Running I/NET Seven as a service on Windows Product Line TAC INET Environment I/NET Seven All supported Operating Systems Cause When you log out of Microsoft Windows or restart the computer, all running processes are shut down. These processes are not resumed at log on or at restart. You have to start I/NET manually again. To get I/NET to start up when the computer restarts, you can run it as a service. Running a program as a service means that it runs in the background, but it is not visible on the Windows task bar. Resolution Use the INET Run Mode tool available on the Community. Alternatively, you can perform the following steps to set/unset the InetIoSrv.exe as a service or application. To register I/NET Seven to run as a service Open a Windows command prompt. Go to Start > Run and type "cmd" Use right-click on the command prompt and select "Run as Administrator" Use commands cd.. (to go back one directory) and cd (to go into a folder) to navigate to the following location: C:\Program Files\INET Seven\ If this is being run on a 64 Bit OS, the location then would be: C:\Program Files (x86)\INET Seven\ Type the following command. This will unregister I/NET as an application inetiosrv /unregserver Type the following command. This will register I/NET to run as a Windows service inetiosrv /service To verify the changes have taken effect Right-click on "My Computer" and select "Manage" Select Services and Applications > Services Look for Inet7Iosrv. It should be set to Automatic. You are now running I/NET as a service. IOSrv will now be running in the background when the PC boots up. This does not require a Log On to the PC, however, you will have to Log On to the PC as a user to launch I/NET or AMT from the desktop icon. You will notice that IOSrv has been logging all AMT transactions, messages and alarms. The SQL Server and Agent were also running in the background receiving data to the database. To set I/NET back to running as an application Open a Windows command prompt. Go to Start > Run and type "cmd" Use right-click on the command prompt and select "Run as Administrator" Use commands cd.. (to go back one directory) and cd (to go into a folder) to navigate to the following location: C:\Program Files\INET Seven\ Type the following command. This will unregister I/NET as a service inetiosrv /unregserver Type the following command. This will register I/NET to run as an application inetiosrv /regserver

Issue Unable to connect to a system that is using Server/Client Configuration. After promoting a stand alone PC to a remote client and clicking on the connect button, an error "No Entries in Database" comes up and the user cannot connect to any of the controllers on the system. After a restart of PC and an attempt to connect to the I/NET System, an error "No entries in database" is seen. Product Line TAC INET Environment I/NET Seven Windows 7, Windows XP, Windows Vista, Windows 10 Cause Some of the possible causes : After promoting a stand alone PC to a remote client the Reference Host information of both the server and the client must be updated with the IP addresses of each other. Bad communication or bad controller that is connecting the C-LAN to the Xenta 527 In some instances when running the I/NET IO Server as a service and after a restart of the PC hardware running a Windows 10 Operating System, it is has been seen to produce this "No entries in database" error. At this stage the reason is currently unknown but the connection to the Xenta 527 is not made and the IO Server service needs to be restarted. Resolution Open I/O Server Hit the Modify button In the Reference Host Column, add the IP address of the server Repeat steps 1-3 on the server, adding the IP address of the remote client. Note: Should the Xenta 527 still not communicate to the controller: Verify that the C-LAN wire is connected properly There is communications between the controllers and the Xenta 527 If not, unplug the C-Lan connector, from all the controllers and bring them online one at a time to determine which one could be bad. Replace possible bad controller and the system should come online again. To correct the issue after a PC hardware restart, two options are available Restart the I/O Server service Change the run mode of the I/O Server to an application. See Running I/NET Seven as a service on Windows for further information on options on how to achieve this.

Issue I/NET will run in application mode, but will quickly shut down when in service mode Product Line TAC INET Environment I/NET Configuration Profile I/NET Seven Cause The I/O Server can be configured to auto shutdown whenever the I/NET Workstation application is closed. If this setting is used, the service will stop whenever I/NET Workstation is closed as well. Resolution Open the I/NET Configuration application. [Start>All Programs>I/NET>INET Config] Click on the Radial button so that I/O Server is maintained when no clients are present. Do NOT use the shutdown option when using I/NET as a service

Issue What address to use to email/SMS alarms from a SmartStruxure Server, Xenta controller, or Vista to a cell phone Product Line Andover Continuum, EcoStruxure Building Operation, TAC INET, TAC Vista Environment Xenta Servers Xenta 511, 527, 701, 711, 721, 731, 913 Vista Server Automation Server Enterprise Server Email, SMS, Text Alarms Cause Vista and SmartStruxure are only capable of sending out SMTP email alarms; however, it can accomplish a "paging" or SMS functionality by sending emails to mobile providers' default email addresses. Resolution For the following services use: T-Mobile 0123456789@tmomail.net Virgin Mobile 0123456789@vmobl.com Cingular 0123456789@cingularme.com Sprint 0123456789@messaging.sprintpcs.com Verizon 0123456789@vtext.com Nextel 0123456789@messaging.nextel.com AT&T 0123456789@txt.att.net 0123456789 = the 10 digit cell phone number When setting up the "From" email address in the Server Setup, it needs to have an @xyz.com for example, at the end of the from address to allow the text message to go through. Note that these addresses could change and you should consult your service provider for details.

Issue Difficulty reading the Display Screen on a 7798 SLI back-light is too dark Product Line TAC INET Environment 7798 SLI Cause It is possible to adjust the brightness of the back-lit SLI display screen. The brightness may have been adjusted too low to allow for easy reading of the screen. Resolution Adjust the brightness level using function keys: F7 increases brightness F8 decreases brightness For more information, refer to TCON 138.

Issue DPU Offline shows up when the Door Configuration is selected from the Summary Controller. Product Line TAC INET Environment All versions of I/NET Cause The Resident I/O Points for those doors are either non existent in the save file, offline or have lost communications to the controller. Resolution Verify that the DPUs are Online and communicating to the Controller by clicking connect Controller/MCU Configuration and verify that the addresses are blue and communicating Select Resident I/O Points and verify that the 08 and 09 points does exist for the respective points If not add and then update the database Select Summary/Door Configuration/ and verify that the doors are now in blue rather than red indicating that they are online. Temporary Individuals have the DPU RES check box, which means the information is stored in the DPU (such as a SCU) until the battery runs out.

Issue Can expansion boards P8UI4AOC and P8UI4AOV be used with a 7718? Product Line TAC INET Environment I/NET Seven P8UI4AOC Expansion Modules P8UI4AOV Expansion Modules 7718 Process Control Unit (PCU) Cause In addition to the eight inputs and eight outputs on the base card, the 7716 supports the control of additional relay outputs and the monitoring of additional AI, DI, and PI inputs connected via the expansion port. These inputs and outputs occupy point addresses 0100 through 0107. Due to address limitations of the 7718, these expansion boards are not compatible with the 7718. Resolution Expansion boards P8UI4AOC and P8UI4AOV cannot be used with a 7718. Refer to 7718 Process Control Unit - TAC INET - Installation Guide TCON106 regarding supported Expansion Modules.
