Issue Understanding the EP1501 and LP1501 downstream device limitations Product Line EcoStruxure Access Expert Environment Access Expert Hosted V3 Cause Downstream device limitations determine how many upstream controllers are required when using these controllers Resolution When choosing to use the EP1501 or LP1501, knowing the limitations of the downstream devices plays an important part in determining the number of controllers needed for a job. The limitation is 8 I/O devices, so if the downstream controller is an MR 50 then a total of 9 readers including the onboard reader can be utilized. Keep in mind that no matter what the mixture is, including MR51e's or MR52's, a total amount of 17 readers can be used or licensed on these controllers

Resolution Depending on application, the V311T or V341 are the closest available valves for replacement. The V341 is of Bronze material, while the V311T is Cast Iron. Depending on the valve size in question, the closest fit is the V311T, while the V341 will require pipe work. See each products data sheet for more information and details.

Issue Which valves sizes are available for the V241 valve? Environment V241 Cause Size specifications for V241 valves. Resolution The V241 valve is available in the following sizes: DN15, DN20, DN25, DN32, DN40, DN50. Some of these are available in different Kvs values. For more information and details, please see the V241 data sheet available on the Extranet.

Issue SCU 1284 won’t communicate to the controller when you turn power on to the device Environment SCU 1284 Cause Product Support Services investigation of SCU12xx field failure returns has revealed that the significant majority of the returns are due to a failure of the RS-485 transceiver IC. Most of the failures are also being described as initial installation failures or "out of the box" failures. Close examination of the failed circuits and the conditions that will prompt failure of the RS-485 IC currently in use on the SCU indicates a significant probability that many, if not most, of the failures are the result of momentarily connecting the TB1 terminal block onto the SCU header with it shifted 1 position to the right. Connection of the TB1 block in a shifted manner will typically cause some relay buzzing noise prompting the installer to recognize the error and correct the position. Unfortunately the RS-485 transceiver will be damaged before you ever hear the relays buzz. Other than TB1 misconnection, the predominant other candidate would be induced transients on the LAN. However, the frequent description of the problem occurring during installation or out-of-the-box tends to point toward TB1 misconnection. Resolution Caution your installation personnel to pay extra close attention to the connection of the TB1 terminal block in order to reduce the SCU failures being precipitated by misconnection. TAC will also be investigating RS-485 transceiver selection and the use of more tolerant versions, and possible end caps on TB1 to inhibit misconnection.

Issue The I/A Series R2 Enterprise Server station fails to start and displays the error: fatal boot - file is used by another process station VM Product Line TAC IA Series Environment I/A Series R2 Enterprise Server Cause Multiple stations may be running on the server simultaneously (e.g., autostart enabled). The station may be open offline while attempting to start. Write protection settings on the PC prevent the Enterprise Server from creating or writing necessary files (e.g., config.db.lock , properties files). Resolution Verify Station Instances Ensure only one station is running on the server. Disable autostart for other stations if necessary. Close Offline Station Confirm the station is not open offline when attempting to start. Check File Permissions Navigate to the Niagara directory and verify that all files and subdirectories are not set to read-only or blocked for writing. Remove write protection and ensure the Enterprise Server software has full access.

Issue What user account type does Continuum require to run correctly What could be causing Continuum or parts of Continuum to stop working or crash Environment Continuum, XP keywords: Account, user, Power User, Administrator Poweruser, Pinpoint, Graphic Cause User log in account may be blocking access to programs or files, can stop Pinpoint graphics from being edited. Resolution XP Once Continuum is installed using a Windows "Administrator" account, a Windows "PowerUser" account will give sufficient access to allow Continuum to run. If a Windows "User" account is used, some parts of Continuum will not operate correctly or may crash. We publish no information on what needs to be enabled/allowed/unlocked to allow a windows "User" or other such account to operate correctly. It is possible to set up an account correctly to run, but this would need to be set up by an IT expert on site, and updates/upgrades to Continuum may require the account setting to be changed.

Issue A variable that is a NV-based CP and named nisse123 (for example), won't work in Xbuilder A variable that is a NV-based NV (i.e. not a CP) and named nci123 won't work in Xbuilder   Environment TAC Xbuilder Cause TAC Vista and TAC XBuilder handles SNVTs differently Resolution The general workaround is to ensure nci are named nci, nvi are named nvi, and nvo are named nvo.

Issue An override command was applied to a Network 8000/DMS standard point on a SIGNAL graphic. The graphic shows the point in override, but the actual point in the field panel is not overridden. Product Line TAC IA Series Environment Network 8000 SIGNAL Cause The override command in SIGNAL does not properly update the field panel point due to a corrupted or outdated override data file. Resolution Clear the override data file and reapply the commands: Shutdown SIGNAL. Open Windows Explorer and navigate to: C:\Windows\Override Delete the file: override.dat Restart SIGNAL. Apply the override commands again. (The override.dat file will be recreated automatically.)

Issue Personnel objects named VisitorX. When the card is issued the name is changed from visitorX to the name of the person the card is issued to. Once the card is returned the name is changed back to visitorX until ready to be reissued. When a list of Access Events is shown the events only show the current name associated with the person and all previous names are lost from the system Environment CyberStation Cause Function as designed. Resolution Create a Custom Attribute for personnel objects (i.e. CardHolderName) and use it to store the actual name of the person holding the Visitor card.

Issue There are many situations that a remote computer wants to monitor and control local Vista values. C/S construction (Client/Server) and B/S construction (Browser/Server) are the two solutions for these situations. Environment Multi-PC environment Vista Cause In many cases this application is needed. Resolution The C/S solution for Vista is Remote Workstation and Vista Server. On the client computer, only the Vista Remote Workstation software needs to be installed. Then it can connect to the Vista Server on the server computer. The Remote Workstation software can be downloaded from here. The B/S solution for Vista is Webstation and Vista Server. On the server computer, Vista Webstation software needs to be installed. Then on the client there is no need to install any software. Just open the IE browser, and type the IP address of the server computer, all the content in the Workstation of server computer can be shown in the client computer. The Webstation software can be downloaded from here.

Issue In some projects, there is demand for consuming application with the existing access control system. I/NET can realize simple consuming function through existing controller and specific card reader for consuming application. In this simple consuming system, one card has only one consuming chance in a specific period of time. For example, this application can be used in the canteen of the plant or company for lunch or supper. Environment Consuming system I/NET Cause In some cases this application is needed. Resolution We can use Anti-passback/Anti-tailgate features of I/NET. The following steps should be followed: Select a separate card reader specific for consuming use. Open the Door parameter in I/NET. Check the Anti-passback and Anti-tailgate options in the Door setting. Set one zone number for the "Entry zone" and "Exit zone". Open the ATS window to set the automatic time schedule. Add an APB Reset time schedule for this door. This step is to set the reset time for the consuming accumulation time period. For example, if just for lunch, one APB reset schedule can be added after the lunch time. And if for additional supper, one more APB reset schedule can be added after supper time. Connect a LED indicator to the DO point of the current door. It is used to indicate that whether this card swiping is valid for the current consuming period. Then the simple consuming application is finished. During each consuming accumulation time period, one card can only have one chance for consuming, which is indicated by the LED. More tries will receive deny information and the LED will not light up.

Issue A customer has a system that has been logging data for several years. They now need to change the name of an object that is actively being logged. The question arises: What name will appear in the logs when reviewing historical data using Dataview? Product Line Satchwell BAS & Sigma Environment Satchwell Sigma Cause Changing the name of a logged object can raise concerns about data continuity and traceability, especially when reviewing historical logs. Resolution When an object name is changed in the system: The new name is immediately passed to the logging setup. From that point forward, all log reviews—including archived and new data—will display the updated object name. This ensures consistency in log presentation but may affect traceability if historical context is needed. Important Note: If maintaining historical naming context is critical (e.g., for audits or legacy references), consider documenting the name change separately or exporting logs prior to the change.

This can be seen on the following screens           To change the Users or Workspaces within the Administrator Groups, go to Users or Workspaces modify the Group Membership here  

Issue What are the point address to be used as lighting circuits? Environment I/NET Lighting controller Cause Only certain points can be used to control lighting circuits. These are reserved. Resolution Use points 0-7 with a bit offset of 0-7. You may also use 8-11 for indirect circuits.

Issue PCU Analog Outputs to transducers do not have consistent performance. The first voltage-to-pneumatic transducers installed worked fine. Additional transducers have been added; and now, none of the transducers operate properly. Environment PCU Voltage-to-Pneumatic transducers Cause The amperage or power draw limitations of the PCU have most likely been exceeded. Resolution Sum up the total current and / or power draw of all the transducers and compare this to the maximum current or power output of the PCU. Reduce the number of transducers to stay within the limitations.
