Issue Default system message No. 19997 Contact Sigma Support is shown in the Sigma Alarm Manager Environment Sigma 4.00 IC-Modbus Cause Sigma System messages are held in a master file, in early versions of Sigma this file could be edited to include messages for new integrations or new error messages. From Sigma 4.0 and later system messages are now hard coded into the system and can no longer be edited. If an undefined system message is received it is likely that a later version of controller firmware is installed in the field and the Sigma software does not contain the newer system message. Resolution If an unknown error message is received, the Sigma software should firstly be upgraded to the latest version. To assist in tracing the source of errors related to IC-Modbus (system messages 19992 - 20002) the exception code from the modbus device describes the failure mode, in Sigma the reason is calculated as follows: System Message Number = 19992 + exception code seen in Modbus message -1 Thus 19992 = Illegal function code 19993 = Illegal data address 19994 = Illegal data value 19995 = Slave device failure 19996 = Acknowledge delayed 19997 = Slave device busy 19998 = ??? (undefined error code ) 19999 = Memory parity error 20000 = ??? (undefined error code) 20001 = Gateway path unavailable 20002 = Gateway target device failed to respond.

Issue Questions on Sigma backup NiMH batteries. Environment X32 X96 NiMH batteries Cause Questions on the battery packs supplied with Sigma X96 controllers, 1. What is the shelf life of these batteries? (average) 2. Can the voltage of these batteries be checked without disconnecting them from the controller, via measurement points on the PSU board? 3. What is the recommended preventative maintenance interval to check the batteries, if at all?   Resolution 1.       Long-term storage for more than a couple of years can damage the cells. They tend to go short-circuit in long-term storage. This is a trait of all NiMH cells. 2.       The battery pack needs to be disconnected from the controller to measure its voltage, else you will be measuring the voltage from the charge circuit. It is feasible to switch off the controller completely (both the mains switch and the battery switch) and measure the voltage by inserting meter probes into the battery connector, past the wires into the back of the connector. Battery voltage is not necessarily a good indicator of battery health. The only way to test battery health is to measure the run-time while operating on battery power, or otherwise to take out the battery pack and use a commercial battery analyser. 3.       As far as I am aware there is no preventative maintenance interval specified, as battery life is dependent on many things, such as temperature, for instance.  

Issue Webstation closes by itself Environment Webstation  Internet Explorer 9 32bit Cause Vista webstation and TGML do have some compatibility issues with Internet Explorer 32 bit that can cause the webstation to log out itself or even close down when login in. Also a Internet Explorer 32 bit needs to have Java 32 bit installed. On a 64 bit machine if you want to run 32 bit make sure the Java 32 bit client is installed. A normal error to see when those happen is:  --- A fatal error has been detected by the Java Runtime Environment: EXCEPTION_ACCESS_VIOLATION (0xc0000005) --- Resolution Following workarounds have been confirmed to help.  Enable the compatibility view in Internet Explorer 9 Upgrade to Internet Explorer 10  Make sure you have Java 32 bit installed.  Use Internet Explorer 64 bit

Issue Trouble with I/NET to Building Operation bindings. Site can bind an internal I/Net AO to a analogue value in Building Operation but the value won't update. Value appears with a blue triangle that says "unresolved".  Environment I/NET Seven together with StruxureWare Building Operation Cause I/NET points are integrated into Building Operation as points. When you upload the device configuration to the Enterprise Server, the configuration and point information are created in the System Tree pane. You edit and command the points as needed, using WorkStation and I/NET Seven editors. There are ten possible point types available in I/NET: Analog input (AI) Analog output (AO) Discrete input (DI) Discrete output (DO) Discrete alarm (DA) Discrete monitor (DM) Discrete control (DC) Digital input (GI) Digital output (GO) Pulsed input (PI) Resolution For any I/NET inputs (AI, DI, DM, GI and PI) it is only possible for operator changes to be made via the Building Operation Properties. It is not possible to programmatically control I/NET inputs and therefore not to be able to bind an output to an I/NET input point. It is also not possible to programmatically change any points Test state, any outputs (AO, DC, DO and GO) Manual state. And finally it is not possible to programmatically acknowledge an alarm. Therefore it is not possible to bind any script, schedule, FB, etc to any I/NET Points Test, Manual, Alarm Acknowledge or input point.

Issue Is it possible to acknowledge an alarm from a TGML graphic? Environment TGML graphics in StruxureWare Building Operation workstation and webstation. Cause Customers may wish to simplify the user interface and have a TGML graphic as the interface for all user operations. Resolution It is not possible to bind to an "acknowledge" attribute of an alarm from TGML, as this is not exposed. Our recommendation would be to use a panel and have an alarm pane in the panel as well as the graphic.

Issue The TAC200 heat controller is obsolete, but data sheet and handbook may still be useful. Environment TAC200 Cause An obsolete product is still in use on sites. Resolution Documentation is available on The Exchange Download Center by searching for "TAC 200."

Issue Can you disable the wireless in StruxureWare Lite Environment StruxureWare Lite site with wireless devices Cause Does the MPM emit radio waves if the Enocean & Zigbee is not configured (enabled) in the controller set up pages Resolution ZigBee is a wireless communication protocol that uses a mesh network between devices. It operates on the 2.4GHz band and is divided in 16 channels. The Zigbee Pro protocol has error-correction and can dynamically add or remove nodes to the mesh without interrupting the communication. A MPM set as a ZigBee Coordinator creates a network (more or less like a wi-fi router) and a MPM set as a ZigBee router will join an existing network. As a rule of thumb the practical distances are around 150ft in building and 300ft open air but heavily depends on the obstacles around. Disabling ZigBee through the Communication Configuration (C2G1) object will prevent data exchange between this MPM and the rest of the network. It will not disable the radio module, which could still be connected to a network. EnOcean is a 'broadcast' type of protocol that operates on 3 frequency bands. North America is currently using 315MHz and will soon be replaced by 902MHz. Europe operates on 868MHz. As a rule of thumb, the practical distances are about 50ft in building but heavily depends on the obstacles around. There is no way to disable the EnOcean module, however if no device is added or no reference to EnOcean commands are used in the scripts, the module will not transmit or receive packets.

Issue How many points per driver can an Enterprise Network Server (ENS) be licensed for? Environment I/A Series G3 ENS Drivers ENS-BAC-NET ENS-BAC-CL ENS-MOD ENS-MOD-SL ENS-OPC ENS-SNMP Cause Each of the ENS base drivers includes support for 500 points. Additional blocks of 500 points each can be added to the license.  Resolution In terms of licensing, there isn't a limit to the number of points each driver can be licensed for. However, the actual number of points used will be dependent on the computer's resources (CPU, memory etc.). 

Issue In some applications, a compression/conex type connection is requested or required. Environment VZ22 VZ32 VZ42 Cause Application requirement. Resolution Unfortunately, no such connection is available through Schneider Electric, and must be provided from external source if required.

Issue FieldServer makes a proprietary version of their gateway for PolarSoft which uses the BACnet protocol but cannot be discovered via the Who-Is service (and therefore does not show up in the ContinuumExplorer). Is there a way to get/set points in the device from Continuum?   Environment CyberStation Cause Continuum cannot communicate with this version of the FieldServer controller. Resolution Continuum cannot 'hardcode' any points in a device that it cannot discover through the BACnet Who-Is service. It must respond to this in order to create any references to it in the SQL database. The customer will need to get a non-proprietary version of the device, i.e., one that supports BACnet Who-Is/I-Am.  

Issue Sometimes when you add some LonWorks nodes in Vista Workstation under one Xenta Server, and click Edit on the Xenta Server to open Xbuilder, the content of Xbuilder doesn't update, and the ones in XBuilder and Workstation doesn't match. Environment Vista Workstation Xbuilder Cause The Xbuilder failed to update according to Workstation Resolution Right click on the "LON" under the Xenta Server in Xbuilder and click "Refresh network from TAC Vista". It will manually update the content in Xbuilder with Vista Workstation. Then Workstation and Xbuilder will match each other.

Issue How to monitor the State of a BACnet object to trigger an alarm when the object is manually disabled. Environment Continuum BACnet Controllers Cause User wants to have an alarm annunciated when someone disables a BACnet object such as an Input or Output. This is fairly simple to configure in the Infinity controllers but there does not seem to be the same functionality in the BACnet EventEnrollment configuration. Resolution The State attribute cannot be monitored directly from the EventEnrollment. You will need to create; (1) a Numeric and (2) a Plain English program that monitors the original object and sets the Numeric to the value of it's State attribute. numIn1State =  In1 state Then setup an EventEnrollment that monitors the Value of the numIn1State numeric and goes into alarm when it is off.

Issue When logging in, user sees error: "BC client Path from registry" If the error is acknowledged, everything works except for the Alarmview. Product Line TAC Vista Environment Vista Cause If a created user does not have access to the Alarmview when logging in, the error appears. Resolution Give the user access to view the Alarmview: Go to $Alarmview Right click on $Alarmview and choose "Authority" Give the user/group that has the problem at least read rights

Issue Satchwell IAC 600 controllers remain Offline when connected to the Xenta. Environment IAC 600 Xenta 555 Cause A Satchwell IAC 600 controller fitted with DDC253 firmware remain Offline when connected to the Xenta 555.  Resolution This firmware is not compatible with the Xenta 555 and must be replaced. As this DDC253 firmware was fitted into an IAC 600 with specific hardware, the firmware cannot be changed, therefore the controller must be replaced.

Issue DMO and SMO from SQL Environment DMO and SMO from SQL Cause A site which was running I/NET and StruxureWare Building Operation, and as required, I/NET is running as a service. The SQL DMO caused an issue with I/NET running as a service and interrupted the INET service. What is SMO and DMO DMO is part of SQL 2005 backwards compatibility. Which has to be installed when going to SQL 2008 to allow the old I/NET database to be imported. With SQL 2008 they now use SMO instead of DMO. You cannot remove DMO without creating a new data base.  Resolution I/NET SQL interface is based on DMO (Distributed Management Objects) so it will not work with SMO (Server Management Objects). That is the reason the backward compatibility must be installed.  Sites that are using a 64 Bit Workstation and 64 bit SQL then there is a 64 bit backward compatibility that should be installed. The 64 bit BCM is in the Support folder on the original install CD called SQLBCM_64Bit.

Issue Unable to find Modbus device on RS-485 line under an Automation Server. Environment Automation Server (AS) Modbus over serial line Cause Common wire is missing. Resolution Connect a common wire to the Shield connection on the COM port terminal

Issue Existing site with a MSC-NC and several MicroSmart controllers no longer communicates.   The user cannot view real-time data.  The MSC-NC is proven defective.  Can a UNC-520 be used in place of the MSC-NC?  There are two, separate MicroSmart trunks connected to the MSC-NC. Environment DMS Niagara R2 Cause Product failure and obsolescence Resolution Remove the MSC-NC and replace it with the UNC-520 running a station with two MicroSmart Services - one per physical controller trunk.

Issue Does Schneider Electric support the Niagara Andover Infinity Driver? Environment Niagara Infinity Driver Infinet Drivers Cause Unable to get Andover Infinity Driver working. Resolution The Andover Infinity Driver was created by and for Tridium.  Schneider Electric do not sell nor support this driver and all enquiries should be referred to Tridium.

Issue How many events can be saved in the Enterprise server version 1.4.1? Environment StruxureWare 1.4.1. Cause The number of events which could be saved in 1.4.0 was 200 000 which some customers have thought is too few. Resolution The number of events which can be saved in the ES version 1.4.1 is increased to 1,5 million.

Issue Restore of SQL Database fails with error message - "The media set has 2 media families but only 1 are provided. All members must be provided.". Environment Continuum Microsoft SQL Cause When the Database was backed up it was setup as a "striped" backup across a number of files. See MSDN article below that explains this in detail. http://social.msdn.microsoft.com/Forums/sqlserver/en-US/abf50e00-c9b0-4809-9e61-43ed8a53e968/the-media-set-has-2-media-families-but-only-1-are-provided?forum=sqltools Resolution Either provide all of the files in the backup set or perform another backup of the database making sure to remove all existing files and selecting a new one.
