Issue Can existing communication wiring from a NETWORK 8000 (ASD) or DMS (MicroSmart) system be reused for a BACnet MS/TP trunk? Product Line TAC IA Series Environment NETWORK 8000 (ASD) cable DMS (MicroSmart) cable BACnet MS/TP Cause ASD and MicroSmart cables were designed for lower baud rates. BACnet MS/TP networks often require higher speeds, which these cables may not reliably support beyond 9600 or 19200 baud, especially over extended distances. Resolution Reuse Conditions: ASD and MicroSmart wiring can be reused for BACnet MS/TP only at 9600 baud, and possibly 19200 baud under limited conditions. For higher baud rates or longer cable runs, replace with BACnet-compliant cable. Recommended Cable Specifications for BACnet MS/TP: Type: Shielded twisted pair Gauge: 18 AWG or 22 AWG Impedance: 100–120 Ω Capacitance: ≤ 30 pF/ft (98 pF/m) Maximum Length: 9600 baud: up to 1200 m (4000 ft) 38400 baud: up to 1200 m (4000 ft) with proper cable Examples: Belden 3105A, 3106A or equivalent Ensure proper network biasing and termination when reusing existing wiring. If communication issues persist, migrate to recommended cabling standards for BACnet MS/TP. Cable Specification Comparison Parameter ASD / MicroSmart Typical Cable BACnet MS/TP Recommended Cable Type Unshielded or basic twisted pair Shielded twisted pair Gauge 22–24 AWG 18–22 AWG Impedance ~70–90 Ω 100–120 Ω Capacitance ~50 pF/ft (164 pF/m) ≤ 30 pF/ft (98 pF/m) Shielding Often none Foil or braided shield Max Segment Length Designed for ASD baud rates 1200 m (4000 ft) at 9600–38400 baud Examples Legacy ASD/DMS cable Belden 3105A, 3106A or equivalent

Issue How can the factory default settings for the Level 3 password and the two serial ports be restored on a DMS-3500? Product Line TAC IA Series Environment DMS-3500 Cause The Level 3 password and serial port settings were changed and need to be reset to factory defaults for system access. Resolution To restore factory defaults for the Level 3 password and serial ports: Power On the DMS-3500. Remove the cover to expose the circuit board. Locate the CONFIG 2-pin connector near the green LED labeled SYS. Move the jumper from one pin to short both pins. Cycle power to the DMS-3500. This clears NOVRAM and restores default password and port assignments without affecting the rest of the configuration or database. After reboot, return the jumper to its original position (one pin). If not returned, new settings will be lost on the next power cycle. Default Settings After Reset: Level 3 Password: 170 Serial Port 1: 9600 1 7 E P N Serial Port 2: 2400 1 7 E P M ⚠ Caution: Always return the jumper to its original position after the reset.

Issue How to delete all or specific parts of the E: Segment in an UltiVist/DMS database. Product Line TAC IA Series Environment UltiVist/DMS Cause The E: Segment database needs to be removed or cleaned up due to outdated or incorrect configuration data. Resolution Use the KILBRNCH tool to delete the required segment. Backup the database before proceeding. Open an OS/2 window and navigate to the FI directory. Disable communications by typing: SET NOFCS=TRUE (This ensures KILBRNCH only deletes offline elements.) At the x:\\FI prompt, run the KILBRNCH command: KILBRNCH FI Example: KILBRNCH \\FI\\FI E:001.12.01.023 E: = Segment 001 = Network ID 12 = Panel ID 01 = DCM ID 023 = Controller ID After completion, re-enable communications: SET NOFCS=FALSE Refresh the E: Segment in UltiVist.

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 Can the Robertshaw DMS T99 sensor be connected to an MNL controller using the Curve Fit object? Product Line TAC IA Series Environment Robertshaw DMS T99 MNL controller Cause The site requires the use of a Robertshaw DMS T99 sensor with an MNL controller, but the sensor’s characteristics differ from standard Balco sensors. Resolution The T99 sensor is a 2000 Ω silicon-based RTD with linearity similar to Balco. To integrate it with an MNL controller: Wiring: Connect the T99 sensor to the MNL controller’s UI input. Add a parallel 2000 Ω ±1% shunt resistor. AI Object Configuration: Select Balco type in the AI object. Curve Fit Adjustment: Use a Curve Fit object to correct temperature readings. Configure X and Y data points as follows: X (Balco temperatures): 52.5, 61.6, 70.0, 78.4, 86.6, 94.8 Y (Corrected T99 temperatures): 32.0, 50.0, 68.0, 86.0, 104.0, 122.0 Note: The A/D degree per count resolution is approximately 0.15°F per count, which is twice that of Balco.

Issue Connection to a DMS MicroPlex MSC-NC is successful; however, attempts to access a networked MicroSmart controller fail. Product Line TAC IA Series Environment DMS MicroPlex MSC-NC MicroSmart Controller Cause The Flash ROM in the MSC-NC requires reloading. Corrupted or incomplete flash memory can prevent proper communication with networked MicroSmart controllers. Resolution Reload the Flash ROM in the MSC-NC: Power down the MSC-NC. Install jumper J1 (located near the processor). Power up the MSC-NC. Connect using DCT. Remove J1 jumper. Perform Alt-L in DCT to start Flash ROM installation. Additional Benefits: Resets backdoor password issues. Removes “ghost” controllers. Corrects non-standard service alarm codes (e.g., 44+service alarm44144144/144).

Issue Can a Belimo damper actuator (e.g., NF-24SR) be powered from the same transformer as a DMS MSC-MPC Microsmart controller? Product Line TAC IA Series Environment Belimo damper actuator DMS MSC-MPC (Microsmart controller) Cause The MSC-MPC controller uses full-wave rectification, while Belimo actuators use half-wave rectification. Sharing the same transformer introduces electrical incompatibility, which can lead to component-level damage in the MSC-MPC controller. Resolution Do not share the same transformer between MSC-MPC controllers and Belimo actuators. Provide separate power supplies for each device to prevent electrical interference and potential damage.

Issue In a Niagara R2/DMS integration, the re-learn of the DMS database fails after some points were deleted in the DMS system. Product Line TAC IA Series Environment Niagara R2 (all versions) DMS (all versions) Cause The DMS driver uses the LOGPT index (1–250) to scan points during the learn process. When points are missing, the DMS panel returns “NOPOINT.” If multiple consecutive “NOPOINT” responses occur, the learn process terminates early. This happens when points have been deleted or re-created, causing gaps in LOGPT assignments. Resolution Adjust the learnNoPointAbortCount property in the DMS driver: Set learnNoPointAbortCount to 250 to ensure all possible points are scanned, even if gaps exist. Note: This will increase the time required for the learn process but guarantees a complete scan. Additional Notes: If the DMS database was reloaded from a saved backup, points will have consecutive LOGPT numbers, and gaps will not occur. Use this setting only when gaps are expected due to point deletion or creation.

Issue Is the MSC-LIM-1 compatible with any DMS revision 9 Microsmart controllers? Product Line TAC IA Series Environment Microsmart controllers revision 9, 10, and 11 MSC-LIM (Local Interface Module) Cause Need for a local controller connection and clarification on compatibility across different Microsmart controller revisions. Resolution MSC-LIM-1 is not compatible with revision 9 Microsmart controllers. It is only compatible with revision 10 and 11 Microsmart controllers. Earlier MSC-LIM versions (pre-08/96) could only access Level 10 controllers addressed below 99. To access controllers addressed higher than 99, the device required a factory upgrade to 11.0A. The latest MSC-LIM (formally MSC-LIM-1) supports Level 10 and 11 Microsmart controllers addressed up to 124.

Issue Two new batteries were installed in a DMS-350A panel, but neither charged to the point of indicating GOOD. The voltage measured at the battery clips with the battery installed reads approximately 4.5 VDC. Product Line TAC IA Series Environment DMS-350A Cause Poor physical connection between the battery and the battery holder contacts prevents proper charging. Resolution Inspect Battery Holder Contacts Check for dirt, corrosion, or misalignment on the contacts. Clean Contacts Use a suitable contact cleaner or a lint-free cloth to remove debris. Adjust Contact Position Gently bend the battery holder contacts to ensure a firm and secure connection with the battery terminals. Verify Voltage After adjustment, confirm that the battery voltage rises above 4.5 VDC and eventually indicates GOOD status.

Issue DMS OPRIF version 11.6 locks up when attempting to tunnel with Niagara R2 or Niagara G3. Product Line TAC IA Series Environment OPRIF 11.6 with a Windows OS. I/A Series Niagara R2 and G3 Cause The default installation path for OPRIF 11.6 is excessively long for Windows OS, causing the application to freeze during tunneling operations. Resolution During installation, avoid the default directory: x:\Documents and Settings\username\Local Settings\Temp Instead, install OPRIF into the root folder of the desired drive (e.g., x:\ ). The installation path can be specified in the extraction screen during setup.

Issue The desktop shortcut created during the installation of DMS OPRIF 11.6 for DCT does not work as expected. Product Line TAC IA Series Environment DMS OPRIF 11.6 running in a Windows OS. Cause The installed shortcut incorrectly calls c350dct instead of the required batch file dct.bat . This prevents the DCT tool from launching properly. Resolution Run DCT Manually Navigate to the DCT folder and run DCT.BAT directly. Modify Desktop Shortcut Edit the shortcut target line from: call c350dct to: call dct.bat Improve Performance Open DCT.BAT in the DCT folder and change: dctgl.exe %1 %2 to: start /low dctgl.exe %1 %2 This runs the process with lower priority, improving system responsiveness.

Issue Which USB-to-Serial adapter should be used with DMS Operator Interface (OPRIF) version 11.6? Product Line TAC IA Series Environment DMS OPRIF 11.6 DMS-350A DMS-3500 Cause Modern PCs often lack built-in RS-232 serial ports, requiring a reliable USB-to-Serial adapter for communication with DMS panels and related devices. Resolution Recommended Adapter: IOGEAR model GU232A This adapter is also suitable for MSC-LIM, MN-CIM, and CBL-002 (DB-9S > DB-9S). Special Note: When using the adapter with MSC-LIM, launch OPRIF from LINKERGL.EXE located in the DMS folder.

Issue How to share or broadcast analog values between multiple I/A Series UNC-520 controllers using a DMS-3500 panel. Product Line TAC IA Series Environment I/A series UNC-520 DMS-3500 Cause The system requires analog values to be broadcast globally across multiple panels. Direct linking of points does not work because the analog input needs conversion from floatStatus to floatPriority for proper handling. Resolution Create Dummy AP Point On each DMS panel receiving a global analog value, create a dummy AP point (UC AP). Assign a name and set AP type to 07 . Configure UNC Learn the new point at the UNC. Select PVALU:WRITE , then click Add and Create. Two objects will appear: AO and DmsGenericAO. Insert Math Object Add a Math object in the workspace. Link pOut of Math object to pIn of AO. This converts the AI from floatStatus to floatPriority . Broadcast Setup Link sinA of the Math object to the analog point in the DMS panel that will be broadcast globally. Edit the Broadcast Channel and assign the correct GLOBAL number. Address Book Configuration For each UNC station, add all peer IP addresses to the AddressBook under PEER setup. MicroSmart Integration For any MicroSmart controller, create an LP point and link it to the DMS AP point. The DMS AP acts as the input for the MicroSmart LP point.

Issue How to distinguish between the Enhanced and Non-Enhanced versions of the MSC-P1502 MicroSmart controller in a DMS system. Product Line TAC IA Series Environment DMS MicroSmart MSC-P1500 series Cause The MSC-P1502 controller was manufactured in two versions: Non-Enhanced: Standard functionality without configurable AI5 & AI6 inputs. Enhanced: Supports AI5 & AI6 configuration for Voltage/mA or resistance input via jumpers J1 & J2. Resolution Identify the version using these methods: Visual Inspection Non-Enhanced: Circuit board labeled MSCA-6160. Enhanced: Circuit board labeled MSCA-6161. If No Label Present Check above AI5 & AI6 inputs for a white box marked “ENHANCED AI” (Enhanced version only). Using OPRIF Both versions display PCB as Controller Type on the greeting screen, so rely on physical board markings for confirmation.

Issue Global point passing (broadcast) between MicroSmart controllers under a DMS system is not functioning as expected. Product Line TAC IA Series Environment DMS MicroSmart Controllers: MSC-L1000 MSC-MPC-001 MSC-P-751 to MSC-P-754 MSC-P-1501 to MSC-P-1504 MSC-V-510, MSC-V-511 MSC-V-521, MSC-V-522 MSC-V-751 to MSC-V-754 Cause Broadcast channel limits vary by controller type: MSC-L1000 / MSC-MPC: TXD and RXD on channels 1–122 MSC-P-75x / MSC-P-150x / MSC-V-51x / MSC-V-52x / MSC-V-75x: TXD on channels 1–122 RXD limited to channels 1–24 If RXD channels exceed these limits, global point passing will fail. Resolution Verify and adjust TXD/RXD channel assignments to stay within supported ranges: For MSC-L1000 and MSC-MPC: TXD and RXD can use channels 1–122 For MSC-P and MSC-V series: TXD: channels 1–122 RXD: channels 1–24 Ensure configuration aligns with these limits to restore global broadcast functionality.

Issue After updating Java (e.g., to Java 7 Update 65 or later), WebStation graphics may appear blank or white. Note: If the error you see is “Error. Click for details” and not a blank window, please refer to the article: WebStation graphics not working after Java updated to Java 7 Update 51. Customers also need clarity on when Java was removed from WebStation and replaced by HTML5. Product Line EcoStruxure Building Operation, TAC Vista Environment Java Building Operation WebStation Cause Compatibility issues between Java and WebStation in TAC Vista or older Building Operation versions. Java applets were historically used for TGML graphics, causing security warnings and browser compatibility problems. Transition to HTML5 technology eliminated these issues. Resolution For Java-related issues (TAC Vista or SBO 1.5 and earlier) Update Java Install the latest Java version (e.g., 1.7u67). On x64 systems, install both x86 and x64 Java versions. If issue persists, perform clean reinstall: Close all browsers. Uninstall all Java versions. Backup exception.sites file: C:\Users\<username>\AppData\LocalLow\Sun\Java\Deployment\security\exception.sites Delete folder: C:\Users\<username>\AppData\LocalLow\Sun Reinstall latest Java (both x86 and x64 if applicable). Verify Java installation using Java uninstall applet. Restore exception.sites file to its original location. Technology Transition Note Pre-2014 (SBO 1.0–1.5) TGML graphics displayed using Java applets. 2014–2015 (SBO 1.6) HTML5 Viewer introduced as Beta in WebStation. Users could enable HTML5 manually; Java remained default. 2015–2016 (SBO 1.7) HTML5 fully implemented as the default graphics viewer. Java completely removed from WebStation. 2017 onward (EBO 2.x and beyond) Modern HTML5 UI with responsive design. No plugins required; optimized for Chrome, Edge, Firefox.

Issue The instance values the Function Block program had when the backup was taken is lost when the backup is restored in an AS-P running in PCT. Product Line EcoStruxure Building Operation Environment Building Operation Project Configuration Tool (PCT) Cause When the program is first initiated, the values for it is written to the database. If the “Program executions” Is turned off, the instance values the program had when the backup was taken is not read. Hence the values are set to 0. On a real AS-P, a Cold start is performed after the restoring of the backup. When restoring a backup on an AS-P in PCT, one or two cold starts are done, followed by an additional warm start at least for the PCT 2. Resolution To get the instance values from the backup when it is restored, the “Program execution”/”Enable program” In PCT should be turned on before the restore is done. Since a warm start is done for the PCT, the issue regarding Retain level vs. FB Backup property needs to be taken into consideration. Refer to Function Block Program - Retain Versus Backup

Issue There is no complete end-to-end guide on how to test SNMP alarms in EcoStruxure Building Operation (EBO). Existing documentation only covers creating SNMP alarms, not validating their functionality. Product Line EcoStruxure Building Operation Environment SNMP Notifications Cause Documentation provides steps for creating SNMP alarms but lacks instructions for testing and verifying alarm notifications. For general information regarding SNMP traps, refer to the following Web Help links: SNMP Notification Distribution Method Create Notification Wizard - Configure SNMP Page Resolution Follow these steps to test SNMP alarms in EBO: Install MIB Browser Download and install MIB Browser from iReasoning. Load Building Operation MIB File Download the Building Operation MIB file. In MIB Browser, go to File → Load MIBs, and select the Building Operation MIB file. Create and Trigger an Alarm in EBO Configure a simple alarm on a digital point in EBO. Ensure the alarm can be triggered manually for testing. Configure SNMP Notification in EBO Create an SNMP notification with the following settings: Address: SNMP manager IP (use localhost if manager is local). User Name: SNMP manager user credentials. In Filter Settings, select Normal and Alarm states. Add condition: Source server = * . Important: Open the SNMP notification object (double-click or press Enter) to access filter settings. Viewing properties alone will not display filters. Enable Trap Receiver in MIB Browser Navigate to Tools → Trap Receiver in MIB Browser. Trigger the Alarm Activate the alarm in EBO. Verify that the SNMP trap appears in the MIB Browser’s Trap Receiver window.

Issue Users need clarification on what happens when a Software Companion subscription is expired or approaching expiration. Key questions: What messages appear in EcoStruxure Building Operation (EBO)? Are email notifications sent to customers? Can expiration notices be silenced at the EBO front end? Product Line EcoStruxure Building Operation Environment EcoStruxure Building Operation subscription licenses Cause The License Enforcement and Information page in Webhelp provides limited details regarding Software Companion subscription expiration behavior. Resolution 1. What messages appear at the EBO level? 30 days before expiration: A banner appears in EBO stating: “System license renewal date is approaching. Please renew.” After expiration: The banner changes to: “System license renewal date has passed. Renewal required.” 2. Are email notifications sent? EBO does NOT send email notifications. Software Companion notifications: Up to two designated Renewers per system receive email reminders at: 6 months 3 months 1 month prior to renewal date Within Software Companion: System status color changes as renewal date approaches Red indicates the renewal date has passed 3. Can the expiration notice be silenced in EBO? Users can temporarily hide the banner using the Hide button. Permanent removal requires applying a valid license (subscription renewal).
