Issue Poor or unreliable ground connection of IO modules can cause controller failure, inputs to stop updating and communications to be poor. Environment Netcontroller IO modules Cause Strings of IO modules were installed on each DIN rail in a panel. One IO module per row had directly landed ground wires, but each of the other modules on the row relied on contact between a metal clip on the back of the module and the DIN rail.  Observed an average of two I/O modules per panel with inadequate earth ground (where this clip was not making an electrically sound connection). In some cases, resting a hand on one of the modules caused a wide variance in the grounding quality. Resolution After installing a panel (not just in the panel fabrication shop), measure each IO module's ground terminal to ground. Do not just assume that each IO module is properly grounded  to the DIN rail via the clip on the back. And do not just assume that the DIN rail is properly grounded - some DIN rail is plated to reduce corrosion and this can increase resistance. If there is (or will be) any vibration or moisture, or there are any other concerns that site conditions may negatively effect grounding of the IO modules in the future, consider grounding each IO module's ground terminal via a conductor to ground.   There is a Technical Product Advisory here that will provide further detail on this.

Issue "An unexpected error occurred" shown while downloading a LonWorks device through a Xenta Server Product Line TAC Vista Environment TAC Xenta Server (511, 527, 555, 701, 711, 721, 731, 913) TAC XBuilder TAC Vista Server Cause There are a couple of reasons that you can get this error message. One is that SSL 3.0 is not enabled in Internet Options for the Windows user running TAC Vista Server. This will keep Vista Server from being able to download a Xenta controller using a Xenta Server.  It will also not let you download and XBuilder project to the Xenta Server, and you can not connect to the browser of the Xenta Server using Internet Explorer. The other reason could be, that while running Vista Server as a service, the Windows account running the service is Local System and that this account does not have SSL 3.0 enabled. This could also occur if you have enabled "System cryptology: Use FIPS compliant algorithms for encrypting, hashing and signing" in the local policy setting. Resolution Enabling SSL 3.0 Go to Control Panel and open Internet Options. Choose the Advanced tab and scroll to the bottom of the Settings list. Near the bottom you will see Use SSL 3.0.  Make sure the Use SSL 3.0 box is checked. Configuring the Windows account running TAC Vista Server Download the TAC Vista Run Mode tool and run it. Under the Service Logon section choose Local User for the Logon Type, select or write the Windows user name and password.

Issue What are the general recommendations for LonWorks system architecture? Product Line TAC Vista, TAC IA Series Environment LNS database LonWorks network Vista Server I/A Series MNL Cause Understanding the different communication speeds and optimal site design can lead to improved performance of LON traffic on a network. Resolution There are three levels supported by LonWorks. TCP/IP 1.25mbs high speed backbone 78Kbs FTT-10 level Our recommendation is to maximize the use of TCP/IP, minimize the use of the 1.25mbs high-speed backbone and use a tiered structure of 78Kbs LON segments. The IP provides high-speed data transfer, which is good. The 1.25mbs high-speed bus works fine, but it has a number of special requirements that must be adhered to for proper operation. The flexibility of this 1.25mbs network is limited for the expansion of new Lonworks segments, whereas the TCP/IP is more in line with current building infrastructure making it easier to expand the LonWorks system. In the TCP/IP there are two options that allow for better communications. Standard TCP/IP configuration that will work well for most middle-sized networks. This is standard with NL220 or Lonmaker installations Orion Stack is an improvement on the standard TCP/IP and can poll multiple values at one time helping improve the TCP/IP response on large networks. More information in setting up an Orion stack improved TCP/IP LonWorks network.

Issue Are any of the Schneider Electric access software products FIPS compliant? Environment FIPS compliant access control Cause New U.S. Government access control regulations. Resolution FIPS Compliance information The Federal Information Processing Standard 140-1 (FIPS 140-1) and its successor FIPS 140-2 are United States Government standards that provide a benchmark for implementing cryptographic software. They specify best practices for implementing crypto algorithms, handling key material and data buffers, and working with the operating system. Both IPSec and the Encrypting Files System (EFS) in Windows 2000, Windows Server 2003 and Windows XP use the FIPS-140-1 evaluated Kernel Mode Cryptographic Module to encrypt the traffic packet data and file contents respectively if configured appropriately with the selections of FIPS compliant algorithms. The FIPS-compliant, kernel-mode, crypto module lets organizations deploy FIPS 140-1-compliant, Internet Protocol Security (IPSec) implementations using: L2TP (Layer Two Tunneling Protocol)/IPSec VPN client and server. L2TP/IPSec tunnels for gateway-to-gateway VPN connections. IPSec tunnels for gateway-to-gateway VPN connections. IPSec-encrypted, end-to-end, network traffic between client and server, and server to server. Currently, I/NET Seven is not FIPS Compliant. There are not any plans to make I/NET Seven FIPS Compliant.

Issue What sensors can be used in Clean Rooms  What sensors can be used outdoors for temperature measurement What sensor can be used in a swimming pool What sensor would be explosive proof What color is the wall sensor and are custom colors available Environment Building Automation System such as I/NET, Vista, or Continuum at a site containing a clean room, swimming pool, or outdoors Cause Questions concerning the uses of Schneider Electric sensors in Clean Room applications Questions concerning temperature sensors for Outdoor installations Questions concerning temperature sensors for swimming pools Questions concerning explosion proof sensors* Questions concerning color and custom colors for sensors Resolution All the Schneider Electric temperature sensors found in the HVAC Sensor Catalogue as well as on iPortal provide high accuracy and can be mounted on the wall, in ducts, or in a J-Box. Appendix A provides the accuracy for each of the temperature sensors. Color: STR series wall sensors are: Front Cover: White NCS S-0500 N Core Plate: White NCS S-0500 N and Gray NCS S-2500 N Base Plate: Gray NCS S 1502-R Manufacturing in custom colors in not available. One option could possibly to have the sensors locally custom finished to meet customer's requirements. While there is not a direct cross reference to RAL colors, our engineering team has found the closest alternates. Please see the attached pdf. Clean Room: Depending on the specified limits of the clean room, the variety of sensors offered by Schneider Electric are possible solutions. Thing you may want to research are the standards required for the site. Clean rooms are a controlled environment where products are manufactured. It is a room in which the concentration of airborne particles is controlled to specified limits. Eliminating sub-micron airborne contamination is really a process of control. These contaminants are generated by people, process, facilities and equipment and must be continually removed from the air. The level to which these particles need to be removed depends upon the standards required. The most frequently used standard is the ISO 14644 Standards, which were first formed from the US Federal Standard 209E Airborne Particulate Cleanliness Classes in Cleanrooms and Clean Zones.  ISO 14644 is a document that establishes standard classes of air cleanliness for airborne particulate levels in cleanrooms and clean zones. Strict rules and procedures are followed to prevent contamination of the manufactured product. The only way to control contamination is to control the total environment. Air flow rates and direction, pressurization, temperature, humidity and specialized filtration all need to be tightly controlled. Outdoor:  Schneider Electrics selection of Outdoor Temperature Sensors are the STO100, 200, 500, & 600. These outdoor sensors are intended for outdoor wall mounting. Variants are available for Vista, I/NET, Continuum and Satchwell systems. The body has a 20mm conduit entry and the product is supplied with a conduit gland. Range -40 to +90 °C Accuracy See Appendix A: Table A, C, F in the attached HVAC Sensor Catalog.pdf Outdoor Temperature Sensor STO100 Order Code 5141100010 Part Number STO100 System Vista, Xenta Outdoor Temperature Sensor STO200 Order Code 5123246000 Part Number STO200 System I/NET Outdoor Temperature Sensor STO500 Order Code 5141104010 Part Number STO500 System Continuum Outdoor Temperature Sensor STO600 Order Code 5126060000 Part Number STO600 System Satchwell Outdoor Temperature Sensor STO600D Order Code 5126000000 Part Number STO600D System Drayton Outdoor Temperature Transmitters STO300 The STO300 transmitter is supplied as a complete unit, comprising a sensing element and an amplifier mounted in a housing which is resistant to ultraviolet light. The transmitter is intended for mounting on an outside wall, on the north side where possible. The transmitter is connected over a 2-wire cable, which serves both as power supply and signal transmission. The reading of the measured signal is made over an external load resistance. Outdoor Temperature Sensor STO300 -50/50 Order Code 006920501 Part Number STO300 -50/50 System All Note for each of these outdoor sensors, find the Description, the Order Code, Part Number, and the System it works with for the iBAS (intelligent Building Automation System) Please note the difference in Weatherproof and Outdoor. I put a lot of these outdoor sensors in at a university in Texas, and always installed in places that were a little protected. I found that under porches, up under the eves and out of the sun, or along a loading dock out of the rain and ice gave me accurate readings. Swimming Pool: In the piping system of a swimming pool is a corrosive environment with steadily harmful and gradually destructive minerals and chlorine in the water which present a challenge finding sensors able to withstand for extended periods of time. Schneider Electric makes several immersion temperature sensors. Beginning on page 12 of the above HVAC Catalogue, there is a variety of immersion sensors for the different iBMS lines.  One example is the STP660 is a Temperature Sensor for the European market, and intended for immersion mounting in pipe or the circulating systems. The stainless steel probe is a good solution but remember,  if the sensor is to be installed in pool water that contains chlorine, the best bet is to use a stainless steel pocket. I suppose it all depends on if sensor is in pipe associated with the secondary pool side of the system or the heating side of the system. If the sensor head is in an area exposed to Chlorine, then there may be an issue.  Chlorine may attack the solder connections of the wired joints inside the sensor. In the old days products from Satchwell used to produce special sensors for such applications where the wire connections were varnished in order to prevent corrosion. I think at the end of the day, our sensor would have a similar life expectancy to other devices in the plant that were no designed for use in such corrosive atmospheres. Explosion proof sensors: Schneider Electric does not manufacture explosion proof sensors. We do not partner with another manufacturer who provides such sensors. The closest is an 3rd party explosion proof enclosure with one of our available sensors. Our sensors are designed for building installations and if in extreme environments, we suggest enclosures.  

Issue Upon rebooting an MP-V, that has not yet gone through a Flow Balance, the Box Flow data goes to zero. Product Line EcoStruxure Building Operation Environment Building Operation Multi-purpose VAV Cause When a box is not yet balanced, the Balanced K-Factor is zero. Part of the calculation of Box Flow is based on the Balanced K-Factor. Resolution There are two workarounds for this issue: Workaround 1: Balance the box Workaround 2: Enter in a number for the Box measured maximum flow and the Hood measured maximum flow. Either option will update the Balanced K-Factor to being a non-zero value.   This has since been fixed and first consolidated in IPC Hotfix 3.01.02.02000 (CP1), and fixed in release firmware release v3.02.01. See details in Box Flow goes to zero on restart, warm start, or cold start in the Known Issues and Solutions community page.
