Warning Issue UNC-520 heartbeat LED had no activity but the UNC appears to be running without issues.  Environment I/A Series Universal Network Controller - UNC-520 Cause The UNC CPU idle is at 0% which resulted in the UNC heartbeat LED not having any activity (always off).  In this case,  this is caused by changing the ControlEngineService executionFrequencies to faster values and objects' executionParameters frequency set to faster or fastest. The station is using large amount of CPU resources.  Resolution To correct this make the following adjustments:  In the ControlEngineService properties, Config tab, change the executionFrequencies back to the default values of fastest at 500ms, faster at 1s, normal at 2s and slower at 5s.    Change the objects' executionParameters frequencies back to the default setting of normal. You can used the AdminTool object to perform a search and replace and changed all the executionParameters frequencies to normal.  There may be a need to change these values from the default values to optimize the UNC performance. Refer to the Niagara Capacities Engineering Notes for details. You should contact Product Support if you are unsure of these settings.

Issue Allowing write access from BACnet Product Line TAC IA Series Environment I/A Series G3 BACnet Integration Cause By default, the BACnet driver provides external BACnet (client) devices "read access" to all exposed (exported to BACnet) objects in the station. Access depends on a station user named "BACnet." If this user does not already exist in the station, the Bacnet driver automatically creates it, upon startup. The BACnet user is initially created without any permissions. Resolution See below which is extracted from the Niagara Ax BACnet Guide: To allow any external writes (from BACnet) to properties of exported components, including invoking commands (actions), you must assign the BACnet user the necessary permissions to those components. For example, to allow an invoked "Active" action from BACnet to an exported BooleanWritable, in addition to making it "BACnet Writable" at priority level 8 when exporting, you must configure the station’s BACnet user to have operator write permissions on that BooleanWritable, at a minimum. Or, if an exported NumericWritable has an alarm extension, and you want to permit external BACnet writes to its "alarm limit" values, configure the BACnet user to have admin write permissions on the exported NumericWritable. In either example, to allow an external BACnet write to a property like "Out Of Service" or "Notify Type," you must give the BACnet user admin write permissions on the BACnet export descriptors. For details about station user security, see "About Security" in the User Guide. Note: BACnet user permissions also apply to writes of any exported files and histories. Also, note that while a password for the BACnet user is technically not needed (for external BACnet access), you should assign one anyway, because of the write permissions typically assigned. Make it a "non-blank" password, and guard this password carefully.

Issue What NEMA or IP rating is a specific product? Environment All devices Cause Is a product protected against water and access by foreign objects? Resolution The Degrees Of Protection document details both the IP rating and NEMA Enclosure charts. The IP rating is made up of 2 digits, the first is the level of protection to foreign objects, the second is the level of protection to water. If a product does not specify any rating for water ingress in it's datasheet then the the second digit will be 0. The first digit relates to the size of a foreign object that can be inserted into the product. Typically many Buildings products will not allow the insertion of a finger (12.5mm approx' 1/2") and offer no water protection, so they would be rated as IP20, however it would be IP10 should they have holes of up to 50mm (approx' 2").

Issue Can the old Robertshaw T99 temperature sensors be integrated to SBO? Product Line EcoStruxure Building Operation, TAC IA Series Environment SBO all versions Cause Retrofit job installation Resolution According to the RTD-DI-16 specification sheet, the T99 sensor can be integrated to SBO as follows with some limitations. Configuration Use an RTD-DI-16 module with a 2 or 3 wire RTD resistive input. Select 1000 ohm for the Sensor class property of the RTD input object. Configure the Conversion Settings properties of the RTD input object near the endpoints of the temperature range to be measured using values from the T99 temperature/resistance table. Configure the remaining properties of the RTD input as needed. Limitations Input Range. An RTD-DI-16 input configured for 1000 ohm operation is limited to an input resistance range of 500 to 2200 ohms. This will limit the temperature range that can be measured with a T99 sensor to ~115 deg. F maximum. Linearity Error. Depending on the range of temperatures to be measured and the needs of the application, linearity error may be significant. This can be corrected by using a script or function block program to linearize the signal based on the T99 temperature/resistance table values.

Issue After upgrading to Niagara G3 3.8 (from 3.7), nested PxIncludes now only partially load and very slowly.  They are not all entirely missing.  After a screen refresh, most will load except for a random few.  Also, they may load all at one moment but not the next.  The same Px file in version 3.7 loads faster with nothing missing. Environment Niagara G3 / AX version 3.8 Cause PxInclude caching is disabled by default in 3.8. Resolution This issue was addressed with the release of an updated bajaui module - version 3.8.38.3.  This version re-enables PxInclude caching.  Download it here.

Issue Trying to use OPRIF to make a few programming changes to a MicroSmart controller. OPRIF is installed on a SIGNAL computer (Windows 98). With SIGNAL disabled, OPRIF is able to start and handshake with the COM port. However the Auto Answer feature is enabled by default and begins an endless loop of trying to synchronize with the modem. The looping effect prevents a proper connection to the DMS to do programming changes. How can the Auto Answer be disabled on startup of OPRIF? Product Line TAC IA Series Environment OPRIF or Operator Interface version 11.4 and higher Cause Initialization file was modified by default Resolution The readme.txt file in the DMS folder explains how to prevent Auto Answer from being enabled on startup of OPRIF. Click here to view the entire readme file. Below is the excerpt on how to disable Auto Answer: Changes to the command strings used for modem-initialization and control The default modem init-string "AT C1 E1 V1 S0=1 S7=51" has been changed. It is now "AT&C1&D2E1V1". If you or your modem don't like this string, you can now override the default. Using NOTEPAD or EDIT, create a file called MODEM.INI in the DMS directory. This file should contain a single line of ASCII, which will be your customized initialization string. The line must begin with the letters "AT", and must not contain the letters "DT". Other than this one restriction, your modem-init string can contain whatever commands your modem requires. Two separate default strings have been defined for turning auto-answer ON and OFF. These may be overridden by creating files with the appropriate names in the DMS directory. To specify a customized string to force your modem to STOP auto-answering, use NOTEPAD or EDIT to create file a called ANSWEROF.INI in the DMS directory. By default, this file would contain the single ASCII line "ATS0=0". If your modem requires a disconnect command, you could instead write a line that reads "ATH ATS0=0". The default autoanswer ON string "ATS0=1", instructs the modem to answer on the first ring. To answer on the third ring, use NOTEPAD or EDIT to create a file called ANSWERON.INI in the DMS directory. It should contain the single ASCII line "ATS0=3". SUMMARY: Description Default String Filename Comment Modem Initialize AT&C1&D2E1V1 \DMS\MODEM.INI Modified in 11.4 Auto-answer On ATS0=1 \DMS\ANSWERON.INI New in 11.4 Auto-answer Off ATS0=0 \DMS\ANSWEROF.INI New in 11.4
