Issue A voltage between 50mV and 500mV at 50Hz is measured at the Digital Input and has raised concern as to it's affect on the Input. Environment b4, i2, b3, xP Modules, IOU modules. (anything with a Digital Input) Cause Concern over effect of induced voltage on the Digital Inputs. Resolution There is an RC filter on those inputs that should protect it at 50Hz for that voltage. The filter will protect down to 15Hz and the Digital Input will not turn on before 1.6V. Although this should not be a problem, and the RC filter should effectively cut this off before it hits the input circuitry, 500mV is still a substantial noise signal on an input and may be indicative of a grounding problem. It would be wise to try to eliminate this induced voltage.

Issue One folder, on a jobsite computer, contains all the DMS backups done over the past several years.  Since each backup contains multiple files, how can the files be identified and then grouped together for easy retrieval in the future? Environment DMS35, DMS350A, and DMS3500 (revisions 9, 10, and 11) Cause Multiple DMS backups were performed from the same jobsite computer. They were not grouped by name or date. All the backup files exist in one folder in a disorganized state. Resolution The files created from a database 'save' for a DMS35 or DMS3500 are: filename.IOC (stores DMS point IDs, records, alarm parameters) filename.UC (stores DMS point configuration elements) filename.PG (stores DMS tables and schedules) filename.UDP (stores UDPs in the DMS panel) The files created from a database 'save' for a DMS350A include the four listed above as well as: filename.Dxx (stores DCM tables, schedules, and other elements) filename.Uxx (stores DCM UDPs) where xx = DCM address 01-32

Issue Selection and installation of a pulsed output module. Product Line Andover Continuum, EcoStruxure Building Operation, Field Devices, Satchwell Sigma, TAC Vista Environment Heat Meter Multical 602 Pulsed output module No pulses Cause Installed card does not give output pulses. Resolution Selection of the output card. The Schneider Electric part number is MAPULSETOPC and this is the equivalent to Kamstrup part number 602-0C This card will provide 2 pulse outputs for energy and volume, CE and CV respectively. Normally, energy (CE) is connected to 16-17 and volume (CV) to 18-19, but other combinations can be selected via the PC program METERTOOL, also used to select pulse duration 32 or 100 ms. The MAPULSETOPC is actually a top module, which means that it is fitted into the top piece of the MC602 calculator, basically the inside LCD cover. This is released by pressing downwards in the middle of the plastic piece on the left, and at the same time pushing the top module towards the left.

Issue A building has come under new ownership and wants to have the license ownership changed Environment I/NET 2.4x Cause I/NET CD Keys are referenced by site and Company name. When a specific building comes under new ownership, they new owner may wish to change the software license to their name. Resolution For Sites using I/NET 2.31 or older: These sites must purchase an upgrade to the I/NET system and ask for a name change as part of the upgrade.   For Sites using a current License Key: Open I/NET and select Help>About Take a screen capture of this screen Email this screen capture as an attachment to expert.services@schneider-electric.com Please include any information you have about the owner name or address the site may be registered as. Note: Please note that you will be billed for this transaction.

Issue A Schedule in a b3 under an Automation Server does not seem to have the same option to clear events that the Automation Server has or that was present when the same b3 is under a bCX in Continuum. Environment Automation Server b3 controllers Cause There is no option to delete multiple exception events from b3 Schedules similar to what can be done in the Automation Server. Resolution  They will need to be removed individually or wait until the exception event expires which should them remove them from the Schedule.

Issue Does Continuum 2.0 SMTP alarm email support encryption? Product Line Andover Continuum Environment SMTP Cyberstation Cause There is a need for encryption on SMTP alarm delivery in Continuum. Resolution Continuum does NOT support encryption for alarm emails sent over SMTP from Cyberstation.

Issue PE Programs cause Locks to go into "Inoperable Mode" Environment Continumm version 1.94 and above Cause Personlized PE Program causes the locks to go into an inoperable mode due to the constant polling of the PIM for lock status based on the program characteristics. Resolution To resolve this issue, please follow these steps: Do not use PE Programs to poll lock status it would minimize battery life Disable all PE Programs that are lock specific. Do not use PE Programs for Schlage Integration.

Issue Using PIN only for the Integration and it is not working. Environment Continuum Version 1.94 and above. Cause The X Driver has a limitation on how it functions with PIN only. Resolution To resolve this issue, DO NOT use PIN only as it is not supported by the X-Driver. If the PIN needs to be used then it must be Card and PIN.

Issue Is there any way to mass change any of the bCX / ACX / NC2 settings as configured from the controllers configuration webpage?  Environment ACX57x0 CX9680 bCX9640 bCX4040 CX9702 Cause Settings need to be changed en-mass for a large number of Controllers. In one particular case there were a large number of ACX57xx’s that needed to have the first and second SNMP alarm target PC's IP addresses changed for all controllers. Resolution There is no way to set all of these at once. As with all of the settings on the controller configuration webpage, they will need to be manually changed one at a time by connecting to each individual controllers configuration webpage.

Issue When an SLR320 light level sensor has power applied a transient voltage (approx. 17VDC) is seen on the output. Environment SLR320 Cause In order to provide dual output capability (voltage and current) with both AC and DC supply, it is necessary to use a capacitor to filter the AC supply. This capacitor is also active in current mode because it is placed behind the rectifier at the G clamp. An additional resistance is added inside to minimize this load current. This load current of the capacitor (which is the cause of transient voltage) cannot be reduced to zero, otherwise the voltage output cannot be used at AC supply within its specification (max. output voltage @ min. load resistance @ min. supply voltage, Y clamp). Resolution This behavior is expected and by design. The transient voltage generated by the load current is settled within approximately 40ms and occurs only at power up. The transmitter is continuously powered so this would not normally be an issue and would have stabilized before a controller that was powered up at the same time would be booted and scanning it's inputs.

Issue Unable to communicate with Assa Abloy  Hubs Environment Continuum Version 1.94 and above Cause The HUB being used is the wrong version and cannot communicate with the XDriver Resolution To resolve this issue, the following steps need to be observed: Verify that the correct XDriver is on the Continuum Panel Verify that the settings on the Comm Port is correct per the installation manual pg 7 Verify that the Global Config Numeric is set to 1001 Verify that the HUB does not have an M on it (this is for a Mercury Integration) Replace the HUB with a standard one and verify  that communication has been restored

Issue In the TAC Xenta 151-D, the nvoAlarmStatus handles the test of the dampers, but the translation of the status is not documented Environment TAC Xenta 151-D Cause nvoAlarmStatusis used to report the actual status of the fire damper tests. Resolution nvoAlarmStatus is a SNVT_state with the use of the following bits: nvoAlarmStatus.bit0 = 1   OBJECT1_CLOSE_TIME_TOO_LONG    nvoAlarmStatus.bit1 = 1   OBJECT1_CLOSE_TIME_TOO_SHORT   nvoAlarmStatus.bit2 = 1   OBJECT1_OPEN_TIME_TOO_LONG     nvoAlarmStatus.bit3 = 1   OBJECT1_OPEN_TIME_TOO_SHORT    nvoAlarmStatus.bit4 = 1   OBJECT2_CLOSE_TIME_TOO_LONG    nvoAlarmStatus.bit5 = 1   OBJECT2_CLOSE_TIME_TOO_SHORT   nvoAlarmStatus.bit6 = 1   OBJECT2_OPEN_TIME_TOO_LONG     nvoAlarmStatus.bit7 = 1   OBJECT2_OPEN_TIME_TOO_SHORT    nvoAlarmStatus.bit8 = 1   OBJECT1_SET_CLOSE_TIME_FAILED nvoAlarmStatus.bit9 = 1   OBJECT1_SET_SELFTEST_OK        nvoAlarmStatus.bit10 = 1  OBJECT1_SET_SELFTEST_FAILED    nvoAlarmStatus.bit11 = 1  OBJECT2_SET_CLOSE_TIME_FAILED nvoAlarmStatus.bit12 = 1  OBJECT2_SET_SELFTEST_OK        nvoAlarmStatus.bit13 = 1  OBJECT2_SET_SELFTEST_FAILED     

Issue It is desired to configure a minimum off time, so when the compressor stops in e.g. heating mode, it will not start again before a minimum time has elapsed in the same mode. This setting is not available in the device. Environment TAC Xenta 121-HP Cause There is no setting for minimum stop time when in the same mode, there is only a minimum stop time between modes. Resolution As a workaround, set the "Activate at" value to something other than zero (say 10%), so that you can use the "Hysteresis" at 10%, and this way get a delay. This way you will get a delay in the most cases, a little time before the controller reacts.

Issue Email alarming is configured correctly but Continuum keeps crashing when alarms are sent as emails. ACCDataServices is the crashing module.   Windows Application log shows two email errors that point to an issue with Outlook. Email, Failed to send email - SendNote in Send function failed. Result is 80070057. Email, Failed to send email -  SubmitMessage failed in CSession::SendNote, Result is 80070057 Environment Continuum Alarming Outlook Cause Outlook account folder is too large and does not have available space for new entries. In this case the folder was 7GB in size with emails going back eight years. Resolution Archive Outlook account folder and truncate to free up space for new emails.  

Issue With the Personnel Import Utility, is it possible to query multiple OU containers? Product Line Andover Continuum Environment Personnel Import Utility (PIU) Cause Need to be able to query multiple OU containers. Similar to below query. Server Name: LDAP://test/DC=test, DC=com (test and com are separate domains) Resolution Unfortunately the query cannot be changed to accommodate this. Different Domains can be specified but it is not possible to go down to the OU level.

Issue Can the Personnel Import Utility update existing Personnel only and not create new Personnel objects if they do not already exist? Environment Personnel Import Utility PIU Cause Need to be able to only modify existing Personnel and not create new ones when performing Personnel import with the PIU. Resolution The way the PIU handles this, to modify existing Personnel or if none exists to create a new one, is "functions as designed". There is no way to stop a new Personnel object from being created when it is unique.

Issue Is a certain version of Technician Tool Mobile Application compatible with all versions of StruxureWare Building Operation? Product Line EcoStruxure Building Operation Environment Building Operation Technician Tool Automation Server Enterprise Server Cause The Technician Tool will always be backwards compatible, meaning that the latest version of the tool will work with any version of SBO. Older versions of the Technician Tool may not work with a newer version of SBO. Resolution Please note: Mobile experience to be replaced with EcoStruxure™ Building Operation v2.0 WebStation. For further information, please refer to Notice of Withdrawal of the Building Operation Technician Tool Always use the latest version of Technician Tool Mobile Application when possible, as that will work with all SBO versions.

Issue When attempting to rename an Automation Server, the following error is shown: Validation Error Validation failed for property 'PrimaryPassword'. Path: '[server path]'. Type 'Password' Cannot set property value to null because the property is not nullable. Environment Automation Server Cause The Automation Server has been cloned using a backup of another Automation Server, and in that process the SMTP server passwords have been set to null. Resolution Configure a password for the primary and secondary SMTP server. It does not matter what the password is set to.

Issue When Forcing a value from SBO, it is just overwritten by the Lua script all the time. Product Line EcoStruxure Building Expert Environment MPM SE8000 Cause By default, the MPM executes the program once every second, so if written simply like: Output_1 = Off the output will be turned Off every second. Resolution Declare a few variables in the Lua script that will help you implement the logic you need, here is an example: var("Override_Status","ME.BV1") var("Override_Value","ME.BV2") if changed.Override_Status and Override_Status == 1 then ME.BO1 = Override_Value elseif changed.Override_Status and Override_Status == 0 then ME.BO1 = ME.BI1 end Basically, an override status points will act as a "Override button", and when it is active, The output will be equal to override value specified in SBO. Else, if it is disabled, the output will be set to what ever you currently have in your script. In the example above, the output will be equal to the input.
