Issue When a Xenta Server alarm object generates and email, the email is accompanied by several emails showing alarms from objects that did not go into alarm. Environment Xenta Server 5.0.2 through 5.1.7 Cause When the system program in the Xenta server polls multiple point simultaneously it may interpret one alarm signal as multiple alarm signals from all polled points. Resolution Option 1 - Edit the Xenta Servers Xbuilder project Change the scan time on all alarm objects so that they are at different scan rates. Generate the project Send the project to target. Option 2 - Connect to the affected I/NET controllers Modify the points in Resident I/O Change the scan rate of each point so that all alarms have different scan rates.

Issue XBuilder crashes when a LNS network is inserted Environment XBuilder LNS Network Cause XBuilder will crash when a LNS network is inserted that contains a XIF file which has multiple signals with the same name. Resolution If Vista 5.0.0 or higher is being used you can create a Vista database solely for the purpose of inserting it into XBuilder to avoid this problem. Otherwise the XIF file will need to be modified to remove the duplicate names and the template replaced with the new XIF file.  

Issue The setpoint values are displayed briefly and then change to 621.X on the Proview display? Environment All LON proview installations. Cause This occurs when the setpoints are being written into network variable inputs (nvi).  The nvi's default to using the receive heartbeat and will fallback to default after the timeout occurs.  Proview does not perform a send heartbeat function as the connection is an nv update and not an actual binding. The receive heartbeat mechanism in the MNL controllers cause the nvi values to fallback to NA upon heartbeat timeout. Resolution The heartbeat can be disabled for the setpoint nvi, however nvi values are stored in RAM (not EEPROM) and will return to default upon a controller power cycle.  The best solution is to use network configuration inputs (nci) for setpoint displays on the Proview.  These do not have the heartbeat issue and the values are maintained in EEPROM so they are not lost following a controller power cycle.

Issue Is it possible to create host bindings to Vista using NL220? Environment Vista 5.1.7 NL220 Cause Yes it is possible but you must use a Loytec network interface Resolution Create binding to the LON interface in NL220 and use the Vista System Plug-in to import the project to Vista

Battery backup had been depleted and was not supplying sufficient voltage to the reader.   Resolution Repair or replace card reader power supply.

Issue The SEQROT object in the Network8000 integration in the AS seems to work with constant input values but not reference pointers. Environment AS version 1.3.0 & 1.3.0 SP1 with Network8000 interface Cause After the object has been defined to use constant inputs those input values must be reset to Null before the reference inputs will be used. Resolution The Analog input constant can be returned to Null by highlighting the value it contains and clicking the delete key.  The field will be empty until a save is done.  With a digital input such as the Rotate stages constant simply highlight the value and click the delete key and it will change to Null.

Issue When trying to edit a OGC graphic from Vista a error message is shown, "Can not find the Symbols file". And the OGC editor is not starting up. Environment Vista 4.2.5 Cause The symbols file used by the OGC graphic editor is not correctly defined. Resolution Open Workstation, click on TAC Vista Right click on $Symbols and select Properties Click on the 'source file name', browse to the $ini folder (in Vista 5.1.7 C:\Program Files\Schneider Electric\TAC Vista 5.1.7), find the symbols.sym file. Click OK

Issue In OPRIF 11.6, the "database save" command does not work.  When pressing "S" for save, the first prompt asks for the drive letter where the files will be saved (i.e. C drive).  After pressing enter, the second prompt requests a filename.  An eight-digit filename can be entered.  A file path is optional.  After pressing enter, a new screen should appear as the database save begins.  However, after pressing enter, the screen returns to the main database menu. There are no errors reported. Environment DMS OPRIF 11.x Cause A graphic screen is missing from the installation of OPRIF.  After entering the driver letter and filename for the database save, a new screen should appear.  The graphic file is requested but doesn't exist.  As a result, the database save command aborts and returns to the main database menu screen. Resolution The simplest solution is to re-install OPRIF 11.6 "overtop" the existing installation.  The missing file(s) will install.

Issue Specifying engineer wants to know the input impedance of the voltage inputs on the MNL-10Rxx / 15Rxx / 20Rxx controllers.  This information is not in the data sheet. Environment MNL-10Rxx controller MNL-15Rxx controller MNL-20Rxx controller Cause Job specification requirement Resolution The minimum input impedance for a MNL-10Rxx /-15Rxx / -20Rxx  UI configured as a voltage type input is 20K ohms.

Please contact your local Product or Account management team, specifying the exact EBO version you require an SBOM for. 

  Issue The IoT alarm is being displayed, and acknowledging the alarm removes it temporarily, but it returns. Product Line EcoStruxure Building Operation Environment Building Operation EnterpriseServer Building Operation Workstation Lead/Shadow enabled System Alarms  Cause In Building Operation version 3.0.1, Cloud Connectivity was enabled at the Automation Server.  The alarm indicates that the Automation Server cannot connect to the Cloud server, whether attached to an Enterprise Server or Standalone, typically because there is no internet access.   By default, the option for Cloud Connectivity is set to Auto. Once the Automation Server is attached to an Enterprise Server, this option is applied in all sub-server settings and controlled from the lead object in the Enterprise Server. Resolution To prevent the alarm from triggering, Navigate to the Enterprise Server Control Panel Under the "Security and Communication" section, select Cloud Connectivity Switch the function from Auto to Disable. This change will be passed down to all sub-servers. Should the alarm not clear, a power cycle may be necessary to clear this alarm. See the following online WebHelp topic, Cloud Connectivity Overview, for further information.

Issue Adjusting the setpoint from the SXWSC3XSELXX device. Product Line EcoStruxure Building Operation Environment Building Operation SmartX Living Space Sensor. Cause SXWSC3XSELXX has plus and minus buttons that could be used for changing setpoint. Resolution Navigate in the System Tree to the Display entry for the SmartX Sensor. Go to the Button and Scene Configuration tab under Properties. Scroll down to Front Menu Button Configuration, change Button 1 function to Change temperature setpoint. Select the tab Advanced, and scroll down to the Feature Control Settings. Set Allow setpoint changes to On. Set max and min limits for the setpoint under Setpoint high limit an Setpoint low limit.   When the plus or minus button is pressed, the Setpoint will change in steps. The size of the steps depends on the difference between the Setpoint high limit and low limit, divided by 10 (when using SI units). In the example above, the difference  between the Setpoint high limit and low limit is 28-18 = 10, so the Setpoint will be changed in step of 1 degree C.  

Warning Hazard of Electric Shock: Remove all power from all devices before removing any covers or doors of the system. Disconnect power at the device and at the power source. Electrostatic Discharge Required: Always discharge static electricity from your person by touching metal prior to handling any hardware. Failure to do so may result in damage to devices. Issue There is an alarm showing after adding a downstream controller Product Line EcoStruxure Access Expert Environment Access Expert Hosted V3 Cause Instructions needed to eliminate the power failure and  tamper alarms showing on newly added downstream devices Resolution When adding downstream devices, for example, An MR50, MR52 or MR16In/Out to an SSC, EP1501 or EP1502 controller, an alarm may show in the hardware tree. To get the controller out of this state, the following steps need to be taken: a. Locate the terminal block(TB) on the panel which contains the connections for CT (Cabinet Tamper) and BA (Power Fault) Note: You may need to consult the specific controller documentation since the TB#  with these connections are different on each board. It will look similar to the following: b. Remove the connector Cut two small pieces of wire, one for each Alarm Use the 2 wires to jumper each connection (CT and BA) to create a closed circuit. This assumes these contacts are not being used for their usual purpose. No resistors are required Place the connector back on the board The downstream devices no longer show alarms for the respective addresses.
