Issue Need to prevent passback in a Continuum access control system. Product Line Andover Continuum Environment Continuum Access Control Cause Access control users may try to "passback" their card in order to have another user enter an area. Resolution The way that anti-passback works in Continuum is that all the Door's entering into an Area that require the feature need to be setup for anti-passback. This then means that any one granted access at any of the Door's is then denied access at the other Door's into that same Area until they have badged out. There are two variations on the anti-passback implementation: Strict anti-passback. This restricts the same card from being used to enter the same Area until that Personnel badges out into an exit Area. It also ensures that the person's current area is adjacent to the area he/she is trying to access so if the system has the person's current area as OUTSIDE and the person tailgates into the premises and then badges at an internal door she will be denied access due to anti-passback violation. Relaxed anti-passback. This also restricts the same card from being used to enter the same Area but will allow access if the Personnel is in any different Area. As long as the Personnel is not currently in the Area they want to enter then they will be allowed in. (See Anti-passback enforcement on area re-entry only)   How to setup To setup anti-passback you will need to have at least two Areas created. One you want to restrict access to and another where they will be coming from. Next, you will need to configure the Door objects entering these Areas for both Entry and Exit. Make sure to define both of these Areas otherwise the anti-passback options will not be selectable. (See Anti-Passback Protection option is not available) Then go to the Entry Options and/or Exit Options tabs and tick "Anti-Passback Protection". This will provide strict anti-passback unless relaxed is enable by the next step. You can enable relaxed anti-passback by ticking the "Allow Entry on an Anti-Passback Violation" option. There is also an option for timed anti-passback, which if ticked, allows access on anti-passback after the "Timed Anti-Passback" time has lapsed.   Possible Solutions When Exit Readers Not Available You do need to have exit readers as well as entry readers to be able to configure and use anti-passback. To restrict access to an Area we need to know the current Area that each Personnel is in, we can only do this with Exit readers. This may not mean having to install exit readers at every entry reader though, there a couple of possibilities. First though, you will need to setup dummy exit readers in the Door objects you want to have anti-passback enabled. This will allow you to access the anti-passback function. The main problem will be that after entering the Area successfully, that same user will not be able to enter again unless they are shown to have exited that Area. There a number of possibilities on how to provide this: Install a single "badge out" reader at the exits for Personnel to badge out before exiting through free egress doors. This reader will be tied to a Door object with an exit area attached. Timed anti-passback could be used with a large enough window to deter tail-gating but still allow the cardholder to exit then enter again normally throughout the day. Could use the "allow access on anti-passback violation" option to monitor (and potentially trigger an alarm at the entry point) to note the violation for latter analysis but still allow the Personnel through.

Issue What Techniques can be used to troubleshoot Modbus TCP/IP X Driver? Product Line Andover Continuum Environment Continuum Modbus TCP/IP X Driver Cause Advice/ tips required to help isolate & determine Modbus IP communications problems. Resolution The first thing to check is that you are using the latest release of the driver and manual, also that it is the correct one for the controller model you are using, currently V2.00002 for the 1st Generation controllers (e.g. Netcontroller CX9900 etc) and V2.00018 for the 2nd Generation controllers (e.g. Netcontroller II and bCX1). Download Modbus TCP/IP xDriver. Ensure you are using only 1 XDriver for all your Modbus IP comms, if say you are using Comm1 as your X Driver enabled port then all of the Modbus IP points must be under Comm1, you cannot have 2 X Driver ports loaded with this X Driver (See Can multiple Modbus TCP/IP XDrivers be installed on a single 2nd Generation NetController?). The following points should be checked with reference to the Modbus TCP/IP X Driver Manual downloaded with the software: Set the X Driver accordingly for Client or Server mode (Client mode and will be polling the 3rd party devices, server mode responds to requests for data). Check that your Configuration point has been setup correctly as a Infinity String and the parameters are correct for the mode you are using. For Client mode check that Param 1 is set to a polling rate that the 3rd party devices can cope with also that Param 3 is long enough for the devices to respond between 20 and 60 seconds. Use Parameter 4 to enable the error logging in an appropriate date format, this will then put the errors into the String array behind this point, ensure you have set the log size to say 50, automatic log and the interval to be 0 (a semi automatic log See How to log data only when a point changes). This will then log the error in the string each time they occur, you can view these errors with a function that loops for the log size printing out each line to the Message Window, or put a number of lines of the error log array lines on a graphic as lines of text. Create a Remote Device Status point to monitor the state of the remotely connected Modbus IP servers, again this can be put on a graphic to show which devices are on/offline. By selectively disabling or removing some of the X Driver points you can limit the polling to certain devices, that way each device can be tested in turn. Another tool that can help debugging Modbus IP comms is Wireshark as it allows you to monitor the IP comms between the Client and the Servers. Check the correct addressing and function codes are used in the polls and that the servers are responding correctly. As per the Compatibility Matrix check that your NCII has a compatible firmware loaded for the Cyberstation software used (2.0x or 2.1x) In Client Mode, ensure the 3rd party system does not poll the driver too fast, see Typical data throughput rates for Modbus XDrivers. Ensure the Xdriver Objects (usually Numerics) have correct details within the Parameter Fields. An incorrectly formatted IP address can cause the Controller to Cold Start following a download. The quickest way to check the Parameters is to load the Controllers with all the objects apart from the Xdriver Configuration String, then create a listview with parameters 1 to 6.  

Issue Setting up the override value to show the damper feedback on an i2/B3 866-v Product Line Andover Continuum, EcoStruxure Building Operation Environment i2/B3 866-V Plain English Script Cause Activate the damper position feature in the 866-V. Resolution SBO: See this video on creating a program that calculates damper feedback position.  Also reference the article How to show damper feedback for an i2/b3 866-V which describes what needs to be done to show damper position and calibrate the damper. Sample objects, code and images showing configuration are supplied.   Continuum: There is a description in the 866-V installation manual on how to activate the damper position feature, but there are some additional pieces of information that this article has been created to address. This was initially to just get the feature working as mentioned in the next section below. Getting the damper feedback operational: Once the end stops are determined initially during the Learn process, the controller can then determine the position of the damper. Create a PE program to set the DamperOutput LCDState = Disabled and back to Enabled in the next line. This will run through its stroke to determine the end stops. ‘Example program named "damperstate" Fall thru, auto start ‘a 2 line program to initialize the stops Line 1 Set damper LCDstate to disabled goto 2 Line 2 Set damper LCDstate to enabled stop To run from the command line Run damperstate Note that the Feedback will not start working until the Damper has gone full stroke in both directions. This will take several minutes. Set the damper point to on or –on depending on the position so it will move Print Damper OverrideValue from a command line or display it on a listview of the damper output after adding the overridevalue column Self Calibration - The LCDState toggle actually activates the "self calibrate" process. It doesn't just enable the feature. It is necessary to know this because you will need to activate the self calibration again whenever the damper is manually moved using the red actuator clutch release button. Using the clutch can cause the damper position to be reported incorrectly. Periodic re-calibration should be as a part of normal procedure for the controller. Once the clutch is used, the damper position will still report, but the value may be incorrect. Re-calibrate recommendation- Use a PE program that recalibrates the damper (i.e. LCDState as mentioned in Section A) on manual command by the service technician on a power cycle or at the end of an occupancy period. Note: For controlling the Damper motor output create an Infinity Output point of type Triac on Channel 1. It can then be opened / Closed like any other Triac output with the use of On, -On or Off commands

Issue General questions and best practices for RS-485 protocol including cable length and terminating resistors Product Line Andover Continuum, EcoStruxure Building Operation Environment MSTP Cause Understanding best practices for installing, cabling, and terminating RS-485 networks can avoid a lot of problems with communication and hours of troubleshooting communication problems. Resolution MS/TP MS/TP stands for Master Slave Token Passing. Each device on the link is considered the master when it has the token. If it does not have immediate need to use the token, it is required to pass the token along to the next device. This is the token passing part. All devices on the link which do not currently have the token are regarded as slaves, and are expected to listen to any messages the current master may have for it. Because all devices take turns being master, the link is effectively peer to peer. Electrically, MS/TP adheres to standard RS-485, physically wired using two-conductor shielded twisted pair cable. RS-485 Cable Specifications Cables used to form the RS-485 network should conform to the following specifications: Wire Size: 22-24 AWG Cable Type: Twisted-pair, copper wire, tinned Shield: Braid Nominal Impedance: 100-120 Velocity of propagation: 78% Capacitance: <12.5 pF/ft between conductors and <22 pF/ft between the conductor connected to ground and the next conductor. Topology Daisy chain bus topology. Star topology can be achieved using Infilink/B-Link repeaters. Maximum Cable Length Cable lengths of up to 4000 ft (1220m) daisy chained from controller to controller on one arm of a star are supported. After 4000 ft (1220m), a signal repeater (b-Link) is required to add more nodes to the network or further extend the cabling. Using a b-Link fiber repeater allows you to extend the length of RS-485 with fiber optic cable, recommended for running cable between buildings and through noisy environments. Maximum Number of Devices TAC's MS/TP RS-485 supports a maximum of 127 nodes overall. Each controller represents a single node on the network. RS-485 Termination The MS/TP field bus requires a 120 ohm terminator resistor at both ends of a daisy chain segment. The following diagram illustrates the connection of the terminator: Also check out the SmartStruxure-RS485-Network Installation Quick-Help video on the Exchange.

Could not learn in a new 3rd Party BACnet device Bacnet 3rd party controller will not respond to Find New Bacnet Devices (Who-Is/I-Am) Resolution Stop the BACnet service in Administrative Tools\ Services. One example would be Cimetrics service Bacstac Protocol Once the BACnet devices have been found the BACnet service can be restarted, although it may be best to uninstall any non-Continuum bacnet software from a CyberStation

Issue OPC Server with third party and alternatives Product Line Andover Continuum, TAC INET Environment System requiring third party connectivity Cause OPC Server to communicate between hardware and the iBMS (intelligent Building Management System). Resolution The OPC server is a software program that converts hardware communication protocol into the OPC protocol. The OPC client software is any program that needs to connect to the hardware. The OPC client uses the OPC server to get data from or send commands to the hardware. OPC Client Servers are used to communicate between BACnet IP interfaces and iBMS (intelligent Building Management System) programs such as TAC I/NET or Andover Continuum. There is also no Continuum OPC Client software to use for a direct OPC link. The best way to integrate from 3rd party EIB or OPC protocols is using BACnet IP on Continuum; there are third party interfaces and gateways that will convert to BACnet/IP and others that go from OPC Client/ Server to BACnet/IP. I/NET OPC For I/NET a great solution is to install a Xenta 913 controller which gives the capability to go with Modbus or BACnet/IP to third party solutions. The I/NET to Xenta 913 allows communication with Continuum BCX, StruxureWare AS-B, and other 3rd Party solutions. Continuum OPC Standard 3rd party gateways are established to communicate between the protocols such as BACnet and Modbus. Andover Continuum has an OPC Server available here. The hardware requirements are Windows NT 4.0 or Win2K. If wanting to run on XP or newer operating systems, please be aware that no testing has not been done with these OS. For more info on the OPC and XDriver, please see OPC Server Integration. Only one instance of the OPC server on a computer. Each system would need a separate PC with license key to connect to the individual systems and host controllers. The Andover Controls OPC server must be running a separate 3rd Party OPC client computer and cannot be on the same computer as CyberStation. From there it is configured to retrieve point values from a the suggested dedicated Infinity (CX) Controller. It is suggested to install a OPC gateway Infinity Controller since this controller will constantly be busy with OPC traffic. Therefore it is the separate third party vendor computer which requires the ACC OPC Server security key, not Cyberstation security key. Both USB and parallel port keys are available. If no choice is available for OS, one alternative is to check on 3rd party OPC servers like Kepware and Matrikon. Note: For Continuum, determine which one of your controllers will become the “Primary Controller” The Server requires that you designate one external Andover Controls Infinity or Continuum controller located on the same network as its “Primary Controller.” This controller must have had the network taught to it prior to selection. (This is done through the “Teach” function in the workstation.) The Server gets its information about the network through this controller. This suggested single controller is designated as the interface through which all point access is obtained. Controller Type Select the type of network where the controller is located. For a NetController, b4920, CX9702 or upgraded Infinity controllers that can be connected to a Continuum network you would select “Continuum”. For older Infinity controllers, select Infinity. Works with any IP level controller. There is no limit on the quantity, but rather it depends on how you tune.

Issue What is the process to replace a CX9400 with a CX9680 NC2? Product Line Andover Continuum Environment Upgrading a CX9200, CX9400 Eclipse, CX9900, CX9940 to a NCII Netcontroller. CMX9924. Model Number, Type change. Cause Where can I get the process to upgrade my obsolete CX controller. Resolution Cyberstation V1.74 SP2 or above is required to support the upgrading process of a CX9200, CX9900 and CX9940 up to a Netcontroller 2. The upgrade process for this is detailed in Appendix B or the NetController II Operating and Technical Reference Guide. For the CX9400 Eclipse controller they require a minimum of V1.91 to support the upgrade. For the older versions of Cyberstation that do not support direct upgrading of a model number, you will need to bring the Netcontroller II on line as a new controller, then in offline editing copy /paste (or Drag /Drop) all objects over to the Netcontroller II. Then go online and fully reload the Netcontroller II and any connected Infinet controllers. The old controller can then be deleted from the system. The objects could also be copied over using edited ASCII dump files if you prefer that method, but either way you may still have to re-animate your Pinpoint graphics unless you upgrade to a version that supports the Netcontroller II replacement. NOTE ACC-LON RS-485 and ACC-LON FTT-10A protocol options A CX9900 may be labeled CPU-8M and a CX9940 labeled CPU-4M. Later CX99 models may have FT added, eg. CPU-8M-FT When replacing a CX9900 or CX9940 it is vital to know if it requires an RS485 or FTT10 IOU module port (if this port is being used) as this CANNOT be modified on site. See article titled No response from I/O module when learning in an IOU This process cannot be used to upgrade the CMX9924 controllers.  The available range of Netcontroller II controllers available has recently been reduced, see PA-00535 "Andover Continuum Offer Optimization"

Issue Site experiencing comm issues on the Infinet or MSTP bus. Controller error logs show many 1465 (Cyclical Redundancy Check) errors. Product Line Andover Continuum Environment Infinet MSTP b3 i2 Controller error log Cause CRC errors are check sum errors. Before a packet is sent, the sending controller calculates a checksum based on the packets contents. This checksum is then appended to the packet. When the packet is delivered, the receiving controller calculates it's own checksum based on the packets contents. If the check sums do not equal, this indicates that somewhere in the delivery process the packet has been altered, usually due to bad cable or connections, controller grounding, or a bad controller transceiver. For additional information on troubleshooting the infinet or mstp bus, see Infinet and MSTP bus troubleshooting. Resolution CRC errors usually indicate poor signal integrity on the physical bus. Infiltration of "noise" on the comm cable due to the presence of high voltage conductors, radio transmissions, etc. In some cases a failed transceiver may be involved but this is generally not the case. Poor controller grounding can also contribute to this issue. Generally CRC errors call for using a scope to assess the signal integrity on a bus.

Issue Interfacing M-Bus meters to Modbus. Product Line Andover Continuum, EcoStruxure Building Operation, Field Devices, Satchwell Sigma Environment Sigma IC3-Modbus Mbus Modbus Kampstrup Heat Meter Multical 601 Cause Multical 601 M-Bus meters are required to be interfaced with the BMS. Resolution A M-Bus/Modbus converter (RS-485, RS-232 or TCP) and configuration software are required. The converter  and software are available from SyxthSense or similar suppliers. Using the converter and software setup the M-Bus/Modbus system without the BMS system connected. The M-Bus/Modbus converter will automatically assign the M-Bus registers as Modbus registers. From the software note the tables and registers used. Create the Modbus registers as required for the BMS system used. For Sigma - Create the gateway.txt, connect and configure the IC3-Modbus.

Issue When using the Modbus RTU X Driver on RS-485 what cable type should be used and what maximum distance would it give? Product Line Andover Continuum, EcoStruxure Building Operation Environment Modbus RS-485 XDriver. bCX1, NC2 AS Cause Recommended cable type required. Resolution The Modbus RTU is a standard RS-485 network and you can use the same networking rules as per the Infinet network. As long as the baud rates are set the same you can even use an Infilink 200 or a B Link to act as a repeater. Unless the Third Party device manufacturer specifies different requirements the Belden 9182 or a similar cable that matches the Infinet specification would be suitable, again as per Infinet rules this would typically allow a maximum end to end distance of 1200 Meters.

Issue What is the latest specification For a Continuum PC Product Line Andover Continuum Environment Cyberstation SQL Server Cause Computer specification required. Resolution The PC specifications for a version does not change from the time of release, so there is no "Latest Specification" as such. For all versions the hardware requirements are defined in the installation guide (Installation.PDF) on the software CD, or in the downloaded zip file from The Exchange Download Center for the version to be used. This document will contain the minimum and recommended specification required for that Cyberstation version on a typical site, if any other software is to be installed on the computer or the computer is to be heavily loaded; the requirements should be increased accordingly. The same RAM and Processor requirements will also apply to the SQL Server on a typical LAN system. You also need to check the Software and Firmware compatibility matrix for older versions of the traditional product lines for details on the compatible operating system requirements for the version to be used. For a V2.01 system the recommended hardware for servers and workstations are: Intel 8 Cores, 2 GHz or better 8Gb RAM 30Gb Available HDD space (NTFS Partition) CD ROM Drive Video resolution: 1024 x 768 pixels Parallel or USB port For larger systems and where there will be a lot of Extended logging or Alarming, the Hard drive, RAM size and processor speed should be increased.  

Issue How do I change the Baud Rate of a field bus (either Infinet or Bacnet MSTP) if there is either an Infilink or B-link on the network? Product Line Andover Continuum, EcoStruxure Building Operation Environment Infinet BACnet Cause The Infilink and B-link must have their baud rate set manually. Resolution All Infinet or Bacnet B3 controllers autobaud on initial startup or when the fieldbus commport is changed from the parent controller's commport editor. The Infilink and B-link must have their baud rate set manually. The proper procedure to change the fieldbus baud rate is to first go to the commport editor and change the fieldbus baud rate. At this point a message is sent to all field bus controllers to change their baud rate. They will all change immediately, however the Infilink and B-link have not yet changed, so the bus will now be in a confused state and there will be offline issues. The next step is to go to the Infilink or B-link repeater and manually change the baud rate to the new setting. At this point the network should work normally, however if the procedure is not followed there may be network issues where you have some controllers that are running at different baud rates causing the network to be totally shut down. If this is the case the way to resolve the issue is to make sure the Infilink or B-link repeater is set to the desired baud rate and power down or reset those controllers on the network so that they will all synch up to the correct Baud Rate upon power up. ** Changing many controllers A method that may help when needing to change the baud rate of many controllers is to bypass the b-link Connect segment 1 of the b-link directly to the BCX comm port and change the baud rate Reconnect the B-link and verify the controllers are now online, repeat the baud change if necessary. Repeat this process for each segment You may still have some isolated controllers that need to be powered off/on.
