Issue What does the Infinity System Variable named Rdr1Connected through Rdr8Connected detect   Environment CX9702   - Rdr1Connected through Rdr2Connected ACX5720 - Rdr1Connected through Rdr4Connected ACX5740 - Rdr1Connected through Rdr8Connected ACX57x0   Cause Information on Infinity System Variable named Rdr1Connected through Rdr8Connected Resolution The  Infinity System Variables named Rdr1Connected, Rdr2Connected, Rdr3Connected, Rdr4Connected, Rdr5Connected, Rdr6Connected, Rdr7Connected and Rdr8Connected are only found on controllers CX9702 and ACX57xx. The value (true or false) can be used to indicate which card reader channels have card readers connected to them. 1. The Controller checks the connection of card readers by physically checking the voltage applied to the reader. This can make the LED appear to flickering with high frequency, although this is normally not visible. 2. LED1 is monitored, if the LED1 connected correctly then RdrXConnected value is true, otherwise it is false.

Issue Added BACnet MS/TP devices to UNC-510, configuring the port to a baud rate of 38.4kbaud and cannot keep the MS/TP port enabled. Environment UNC-510 with BACnet 527i jar file Cause Maximum baud rate for the RS-485 port(s) on a UNC-510 is 19.2kbaud. Resolution Must set the baud rate for the MS/TP driver to 9600 or 19,200 baud.   Faster baud rates are not supported by the UNC-510 hardware. If adding the BACnet jar file to a previously loaded UNC, you must also add the following line driver.mstp=tridium.nre.vxworks.mstp.VxWorksMstpDriver to the drivers.properties file in the UNC.  Please note that the information in this line is case sensitive and must be entered as shown.

Environment WorkPlace Tech Cause Enable "Center Selection on Zoom" in WorkPlace Tech. Resolution In WorkPlace Tech, choose Tools - Visio Options. Select the "General" tab. Check the box for "Center Selection on Zoom" and click OK. Now, after choosing "Find Object" or "Find Reference" the selected object will appear in the center of the window.

Issue All the correct $LAN objects are setup in the Vista Master and Slave but neither will communicate with each other. If you check the nodes, the connection status shows connected but the Servers will not be online. Environment Vista 5 Cause The server has had the DMZ zone settings Unchecked. This will prevent Server to Server communications. Resolution Recheck the Server DMZ setting back to the standard install defaults.

Issue Getting LON messages TException E_QUEUE_FULL {LonAsyncRequest} in the standard output window. Environment R2, Niagara, Lon Service Cause If also in the message there is a line that includes: "lonextras.control.PollSnvtTempSetptCmd.execute" these messages are being caused by the use of the special object from the LonExtras jar called PollSnvtTempSetptCmd.  Resolution When the station is booting up the PollSnvtTempSetptCmd object  will begin its polling function before the station has finished rebooting causing the queue to fill up before the station starts.  There is an object in the LonWorks jar - Conversion container called SnvtTempSetptCmd that will perform the same function as the PollSnvtTempSetptCmd except it does not poll which is not necessary in most cases.  Replace all PollSnvtTempSetptCmd objects in the station with the SnvtTempSetptCmd object.

Issue Does the Enterprise Server license have a 'node count' like the server license in Niagara R2? Environment SmartStruxure Niagara R2 Cause Comparing the order processes between I/A Niagara R2 and SmartStruxure Resolution The Enterprise Server has an open license.  There is no 'node count' built into it as is the case with Niagara R2. Keep in mind that version 1.3 of SmartStruxure supports a maximum of 32 AS controllers (for optimum system performance).

Issue For a high temperature application, how can a TS-8204 be programmed to read accurately when connected to a MNL controller? Environment TS-8204 Cause Require instruction on configuring the TS-8204 temperature sensor for accurate reading. Resolution Connect the TS-8204 sensor and install a 2.49 kohm resistor in parallel (1% resistor or better). Set the Analog Input object to Balco and link the output to a Curve Fit object. Curve Fit objects are supported only on controllers with Rev.3. They are not supported on VAV controllers. Configure the Curve Fit X and Y data points as follows: Data Point X1 10.8 Data Point X2 34.5 Data Point X3 57.0 Data Point X4 78.0 Data Point X5 97.8 Data Point X6 116.4 Data Point Y1 200 Data Point Y2 240 Data Point Y3 280 Data Point Y4 320 Data Point Y5 360 Data Point Y6 400

Issue Setting up a single user (SQLExpress 2005) v1.93 CyberStation and the SQL Service Manager is not popping up like it should (on the Windows taskbar). Environment Standalone CyberStation SQLExpress 2005 Cause Previous versions of CyberStation had a SQL Service Manager application in the Windows taskbar. When installing a standalone v1.93 CyberStation this application is not there. Resolution SQLExpress 2005 does not install that application. This application is not required to run CyberStation.  If for some reason there is a need to stop SQL Server there is a workaround. Go to Control Panel>>Administrative Tools>>Services. Then scroll down to SQL Server (SQLExpress). You can stop SQLExpress by right-clicking it.    

Issue The AI Objects were all operating correctly and then failed. Instead of showing 20.0 (default range) they all show their last recorded value. On testing the inputs, the devices return to a different value and then the Temperature detectors all read 150°C with the Heat Flow Rates at 0m 3 /hr. Environment AI Analogue Input Defaults Out of range incorrect values Cause The controller slot allocation is incorrectly configured to show the slot as being empty. Resolution Correctly allocate the slot as being an AI Download the controller configuration

Product Line EcoStruxure Access Expert Environment Access Expert Hosted Software Access Expert Premise Software Cause The tags are meant to be on separate permissions and shouldn't be used on the same individual permission Resolution Tags and permissions should be set up as illustrated:

Issue What is a quick way to read a dynamic value from LNSDDE server? Environment InVue Cause Trying to confirm if the value of a snvt is updating and reading accurately - without using InVue. Resolution LNSDDE server and Microsoft Excel are both DDE compatible. Open a new sheet or book in Excel. Find the snvt in LNSDDE and copy / paste the link into one of the cells in Excel.  After hitting enter, the cell will display the dynamic value of the selected snvt. This is a good way to troubleshoot the LON programming and controller communication from the field all the way back to the server - without adding InVue programming to the troubleshooting process.
