Issue How to identify controllers in a DMS system that do not support MicroSmart functionality. Product Line TAC IA Series Environment DMS Installations Cause Older DMS controllers manufactured prior to revision 9.X were not designed with MicroSmart capability. These units are not referenced in Niagara DMS/MicroSmart integration documentation. Resolution Controllers without MicroSmart capability are accessed exclusively through DMS programming. MicroSmart functionality cannot be added to these controllers. Common non-MicroSmart controller models include: Slave CO/CI Module: N604-002, N604-012 Slave AI Module: N604-003 Slave Pneumatic Motherboard: N604-004 Slave AO Module: N604-016, N604-017 General Purpose Slave Module: N604-021, N604-025 These controllers can coexist on the same trunk with MicroSmart controllers (revision 9.2, 10.X, or 11.X) if: Slave controllers have revision 9.0 firmware installed. The trunk uses a 2-wire design (not 4-wire). For additional details, refer to Tech Tip #350-95-03 (Attachment: TT350-95-03.pdf).

Issue How to configure an analog input on a DMS MicroSmart controller to function as a voltage input. Environment MSC-MPC (Revision 10) MSC-MPC-001 (Revision 11) Product Line TAC IA Series Cause The controller needs to accept voltage signals from sensors, but analog inputs must be configured correctly to interpret voltage rather than other signal types. Resolution To configure an analog input as a voltage input: Reference: MSC-MPC Install Instructions (F-24804-4)

Issue When integrating Microsmart controllers with Niagara G3 using the DMS driver, Mode Control points learned as Numeric Points cannot be modified directly. How can the stage setpoints (PVALU elements) be changed from the Niagara G3 station? Product Line TAC IA Series Environment Niagara G3 Microsmart driver Microsmart controllers Cause Mode Control points are learned into Niagara G3 as Numeric Points without writable options, preventing direct modification of stage setpoints (PVALU elements) from the station interface. Resolution Add PVALU Element to Database: Locate the Mode Control point and add the PVALU element for the specific stage to the Niagara G3 database. Update Command String and Index: Modify the Command String to include the PVALU element. Set the Index value to match the PVALU element (e.g., Index = 6 corresponds to PVALU,6 ). Enable Writable Action: After configuration, right-click on the Numeric Point in Niagara G3 to access an action item allowing modification of the PVALU element. Result: You can now adjust stage setpoints for Mode Control points directly from the Niagara G3 station interface.

Issue How to configure an analog input on a DMS MicroSmart controller to function as a contact input when no dedicated contact inputs are available. Product Line TAC IA Series Environment MSC-MPC (Revision 10) MSC-MPC-001 (Revision 11) Cause No contact inputs available on the MSC-MPC Resolution Below are illustrations and explanations on how to configure an analog input as a contact input.  

Issue When wiring a TS-58011-774 Platinum RTD sensor to a DMS Microsmart MSC-MPC controller, what are the acceptable offset values for accurate temperature readings? Can the wire length exceed 200 feet? Product Line TAC IA Series Environment DMS Microsmart controllers TS-58011-774 Platinum RTD sensor Cause A significant offset (approximately 6°F) was required to match readings with a handheld calibration device, raising concerns about wiring length and sensor accuracy. Resolution Offset Values: There is no fixed maximum or minimum offset value. Proper wiring minimizes the need for large offsets. Wire Length: Do not exceed 200 feet. Recommended Cable: Belden #9501 (AWG24). Calibration Steps: Review the sensor installation guide (F-24874) for Software Setup (page 3). Use the temperature/resistance table (page 5) to verify sensor accuracy. Apply appropriate offset values to correct wire-induced error. If necessary, use SOCALC (page 4) to create custom SCALE and OFSET values. Reference: TS-58000 Series Platinum RTD Room Sensor Installation Guidelines (F-24874)

If public connectivity is not available: Download the attached TAC_LLC.certificate. Use Workbench to import the downloaded certificate file.

Issue In a DMS installation, a controller listed as SAI in OPRIF does not appear as a Microsmart controller, even though its points update correctly. Users are unsure how to save its database. Product Line TAC IA Series Environment DMS (all revisions) Cause The SAI controller is an early-generation device designed for the DMS product line. It is a Slave AI Module (part number N604-003) with six analog inputs and firmware revision 8.x. Unlike Microsmart controllers, the SAI is not a smart controller and does not store or require a database. Resolution The SAI controller does not support database storage; therefore, there is no need to back up its database. All analog input points for the SAI must be created and managed directly in the DMS system. Identification tips: Look for part number N604-003 on the controller sticker. Check the PCB for an IC labeled with firmware 8.x. Reference diagram: SAI Module Figure. 

Issue Communication failures with Microsmart controllers on the DMS bus network. Product Line TAC IA Series Environment Microsmart controllers (all models installed with revision 9.x, 10.x, or 11.x firmware) Cause Common causes include: Incorrect power supply wiring or insufficient voltage Shared power between controllers and field devices Exceeding maximum controller count per RS-485 segment Improper network topology or cable type Missing or incorrectly installed End-of-Line (EOL) modules Ground loops or shield continuity issues Duplicate or illegal point names in controller database Faulty line drivers or incorrect address switch settings Resolution The following checklist provides several settings/configurations to review when faced with a communication problem at the controller level. The content was compiled from different resources, summarized, and laid out in an easy-to-use manner so as to provide a quick-reference document. Do all controllers have a power supply? Each takes 24 VAC from a Class 2 transformer ACTION: Confirm with a voltmeter. If no voltage present, check on-board fuse and then the local circuit breaker. Note: Do NOT ground the transformer’s secondary when powering a MSC-MPC-001. With other controller types, the secondary is grounded. If voltage is present, must be within tolerances (20.4 to 30 VAC) Confirm power (VA) requirements. Varies per controller (see installation instructions) Do the affected controllers share a common power supply? The MSC-MPC-001 must have its own DEDICATED power supply Other controller types can share the same AC transformer provided the VA rating is adequate ACTION: Review power wiring (see installation instructions) Do the affected controllers share a common power supply with output field devices? Power for the controllers and power for the output devices MUST REMAIN SEPARATE ACTION: Review controller and field device power wiring (see installation instructions) In addition, avoid wiring any half-wave and fullwave powered devices to the same transformer. How many MicroSmart controllers exist? Firmware revision 9, 10, & 11 family controllers can communicate on the same RS-485 wire segment simultaneously Maximum per RS-485 segment = 30 (31 if no repeater is installed) ACTION: Determine controller count If there are more than 31, a repeater/router is required If there are more than 62, only firmware revision 11 family controllers can be physically addressed higher than 62 Connect the first 30 controllers (isolate any additional nodes) and attempt/stabilize communications. Any repeaters installed? Allows the connection of two or more RS-485 wire segments Extends the maximum controller count by 30 (maximum of 124 addressable nodes supported) ACTION: Identify model number Review settings using its installation instructions Replace line drivers with known, good ones (Part# E21-1144) How rapidly is the Watch Dog Timer (WDT) LED blinking? Once / second = proper network communication A controller’s logical address is always one higher than the number calculated by the switch settings. For example, if all switches are OFF (binary equivalent of 0), the controller’s logical address is 1. If switches 1 & 2 are ON (binary equivalent of 3), the controller address is 4. Network wire connections ARE polarity sensitive. ACTION: Review LED activity No blinking but illuminated Verify proper power requirements & wiring (see installation instructions) Perform a hardware clear (place all address switches in the ON position and power cycle the controller) No blinking & not illuminated Check the on-board fuse Blinking faster than once / second Check the address switch for proper position. Verify address is not duplicated on the network Check the network connector and ensure it is properly inserted Ensure the + wire and – wire are properly identified and the shield wire is also connected. What is the length and topology of the controller trunk? Bus Topology Daisy-chain (no tees) 4000ft/1219m maximum wire length Trunk wiring is polarity sensitive Recommended cable: 24 AWG twisted-pair, shielded General Purpose: Under 1000ft, Belden#9501 Over 1000ft, Alpha#9823C Plenum & Riser-Rated: Under 1000ft, Belden#89503 Over 1000ft, Belden#89182 ACTION: Review the following: Ensure two EOL modules are installed. Each module must be installed correctly (black dot on module in the same corner as the white dot on the circuit board) Remove each EOL and check for following resistances: Pins 1-8: 3.3 kohms Pins 3-6: 150 ohms Pins 4-5: 3.3 kohms Ensure there are no ground loops in the + and – wires. To do this, use a multi-meter & measure the + and – wires, separately to earth ground Ensure the shield wire is continuous throughout the entire length of the trunk and connected to a solid earth ground in only one location Replace line drivers on the controllers (Part# E21-661). Check trunk voltages: + to earth ground: 2.2 – 2.6 Vdc – to earth ground: 2.2 – 2.6 Vdc If 0 Vdc or 5 Vdc is detected, check other controllers for bad line drivers. Determine cable used. If it is shielded, connect it to earth ground in ONE location through a 470 kK, ¼ watt resistor. The shield must be continuous throughout the wire segment. What is the condition of the controller database? ACTION: Review the controller database Illegal point names must be corrected. Illegal characters are: / # * : ; $ = | &. Duplicate point names must be corrected Will Operator Interface (Part# PS-OPRIF) communicate to the controller? Direct connection to a controller can only be done with the Firmware Revision 10 & 11 Families Accessing a networked controller through a direct connection using a MSC-LIM is possible but very slow (300 baud maximum). It is only recommended for checking communication status and not for application programming. It will also require a master controller (DMS35/350A/3500) ACTION: Attempt an upload of the controller database Requires a Laptop Interface Module (Part# MSC-LIM) Operator Interface version 11.41 and 11.6 both support direct connection to a controller If communication fails to work, try another controller to eliminate the pc and interface cabling from the troubleshooting process

Issue Customers using Device Administrator for offline license activation in EBO 7.0.3 face challenges due to changes in how entitlements are delivered via Software Companion. Product Line EcoStruxure Building Operation Environment Building Operation Device Administrator (v7) Software Companion Portal FlexNet Licensing Portal Offline systems (no internet access) Cause The current Software Companion tool does not generate an HTML entitlement certificate compatible with Device Administrator. Instead, it provides a PDF summary, which the Device Administrator cannot read or import. Resolution The simplest way is to enable Internet access for Device Administrator and add the entitlement ID. To activate licenses offline in Device Administrator: Do not use the PDF summary generated by Software Companion — it is not compatible with Device Administrator. There are several options available, each differing in complexity and time requirements. Webhelp(Adding an Entitlement without the HTML file when a Field Server is not Connected to License Server (FNO)), users can follow the follwing steps: In Device Administrator, click Entitlements. Click the Add Entitlement down arrow and click Manually Enter the entitlement ID. Click Next. Click Skip. If you know that you do not have any server connected to internet in the list, click Skip. If you do not click Skip, Device Administrator goes through all servers in your list until it finds one that is connected to internet. In the Entitlement Products - Enter Manually list , enter the Activation ID, Description and seat count for the product. Click Add Product , to add more products. Click Add. Note: It is recommended to verify the Activation ID, Description, and seat count in FlexNet Operations End-User Portal before proceeding with the steps. When there is no connection between the EcoStruxure BMS Server and License Activation Server, Device Administrator cannot synchronize the number of licenses in the entitlement that are available for activation. Instead, Device Administrator assumes that all licenses that was purchased can be activated.  Access the FlexNet Licensing Portal: FlexNet Operations End-User Portal Log in using the Entitlement ID. List all Entitlements. Select one Activation ID Use the View Certificate option. Download and save the certificate locally in HTML format. When using Save As - ensure you select the "Webpage, complete (*htm;*html) option  Repeat for each Activation ID listed in the Entitlement Import each HTML certificate into Device Administrator to load the entitlement offline. Create a server list away from the site, using Device Administrator, that has Internet access. Caution: this will wipe the current server list, remove all certificates (if used), and remove all servers added to Device Administrator. If the server list has already been created on site, save and export this list. Off-site or on a PC with Internet access, import (from step 1) or create a new server list in Device Administrator. Add the necessary entitlement IDs. Save and export the server list. Back on the on-site PC, import the exported server list to Device Administrator. If using a new server list (that is, no servers added from Step 1), add the required certificates and servers. Save this new list. It is advisable to export it as a backup in case of any issues. Proceed with the offline activation. EcoStruxure BMS Server Licensing on Servers not Connected to Internet Workflow. Once activated, remember to save and export the list for safekeeping. Comment: Investigation into why Software Companion does not generate HTML certificates is ongoing.  Device Administrator still requires either the HTML certificate or manual entry of activation IDs.

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.
