Issue Graphics do not display correctly in Sigma 4.06 or above How to upgrade Sigma graphics to Sigma 4.06 or above Environment Sigma 4.06 or above Sigma Graphics Cause Sigma 4.06 or above has been installed and after the graphics have been converted from the SGI or the DRW format to SWC format, the graphics do not display and are blank. Resolution Upgrading from earlier releases of Sigma or BAS. BAS (drw format) Place drw files into C:\bas\data\graphics\slides, the images need to be placed in the appropriate directories as if they are in BAS i.e. animations or pictures. In Sigma 4.06, go to  C:\sigma\binutils and run DrwSWCConvrt.exe. Copy the original drw files into a safe place for archiving/backup. In Sigma 4.06 go to C:\sigma\binutils and run SigUpgrade.exe. Before 4.05 (sgi format) Place sgi files into C:\sigma\data\sgi\slides, the images need to be placed in the directory where they are mapped to in the sgi graphic. In Sigma 4.06 go to C:\sigma\binutils and run SgiConvert.exe. Copy the original sgi files into a safe place for archiving/backup. In Sigma 4.06 go to C:\sigma\binutils and run SigUpgrade.exe. At 4.05 (swc format) In Sigma 4.06 or above go to C:\sigma\binutils and run SigUpgrade.exe. For further detail regarding the upgrade process download Sigma 4.06 Release Note

Issue Compatible GSM Modem for use with the I/A Series G3 SMS Driver Environment I/A Series G3 Cause An externally purchased GSM modem is required to be used for sending out alarms in an I/A Series G3 system via the G3 SMS driver. Resolution The SMS driver has been tested with Siemens MC35 GSM modem. Technically the driver should work with any GSM modem providing the GSM standard has been implemented properly by the manufacturer. Product Support have tested the Siemens MC35 equivalent modems from Cinterion with the G3 SMS driver (https://www.gemalto.com/m2m). The Cinterion devices, MC35i and MC55i have been used on several sites with no issues reported.

Issue Should the Modbus master (eg Xenta 913) also be terminated if it is in the middle of the Modbus bus? Environment Xenta Server with Modbus capabilities Xenta 511, 527, 701, 711, 721, 731, 913 Cause There are a number of installation possibilities/restrictions that may mean that the Modbus master does not always end up at one of the ends of the communication field bus. Resolution Only the ends of the bus should be terminated (see below).   More information is available for Modbus.org at the following link: Modbus over serial line specification and implementation guide V1.02.

Issue DC2100 series Optimiser / Compensator Controller requires resetting to default values due to exposure to electrical corruption. Environment DC2100 series Optimiser / Compensator Controller installed to control Variable Temperature Mixing Valve, Boiler/s, Pumps etc. 2100H DC 2100 Cause DC2100 series Optimiser / Compensator Controller has been exposed to electrical corruption. Resolution DC2100 series Optimiser / Compensator Controller may be reset to default values as follows :-  Isolate power to Controller. Open Door of Controller. Locate PCB on rear of Controller Door. Locate pair of Steel Pins (marked PL1) on PCB. Link out pair of Steel Pins for 10 seconds approx. Remove Link. Close Door of Controller. Reinstate power to Controller. Re-programme Controller. Re-programming procedure for the DC2100 series Optimiser / Compensator Controller may be viewed here. Should the above reset to default values procedure fail to enable the DC2100 series Optimiser / Compensator Controller to be re-programmed then replacement of the Controller may need to be considered. POSSIBLE REPLACEMENT  The most common control application to which theDC2100 series Optimiser / Compensator Controller may be applied comprises the following combination of inputs and outputs.  Outside Air Temperature Sensor Inside Air Temperature Sensor Compensated Heating Temperature Sensor Variable Temperature Heating Circuit Valve Actuator Boiler/s (2 maximum) H W S On/Off output (independent) Should such inputs and outputs be confirmed then the DC1100 Optimiser / Compensator may be installed in place of the DC2100 series Optimiser / Compensator Controller. Details of the DC1100 Optimiser / Compensator Controller may be viewed here. Drayton A7xx series Sensors connected to the DC2100 Optimiser / Compensator Controller are compatible with the DC1100 Optimiser / Compensator Controller and may therefore be retained. N.B. It should be noted that where a DC2100 series Optimiser / Compensator Controller is included in an installation of a more complex nature then an alternative solution utilizing different products may need to be considered In such installations not only will the DC2100 series Optimiser / Compensator Controller need to be replaced but its associated Sensors will also need to be replaced. Resolutions to such installations may best be determined following a review of the control system installed by a member of the local Schneider Electric office.

Issue How to determine who is logged into the Continuum system and onto which workstation? Product Line Andover Continuum Environment CyberStation Cause Is it possible to see via a Listview or Pinpoint who is logged into Continuum and onto which workstation?   Resolution There is no "live" means to see who is logged into what workstation. However, a listview of ActivityEvent filtered by today and action code 15 and 16 and auto-refreshing every 30 seconds is pretty close. This listview will show what user logged in and when to which workstation. It will show the same information for users logging off. So one can deduce who is currently on which workstation. Simply download and unzip this dump file and import it into the root of Continuum Explorer and run it.
