Issue For Modbus RTU Xdriver, if poll too much points or polling is too fast with one xdriver will cause reading 0 issue. Environment Continuum 1.9X BCX1-CR, Modbus RTU xdriver Cause Poll too much points with one xdriver or polling is too fast ,more than 2 polls per second More than one programs polling at the same time Resolution  Make sure there is only 1 PE program running to Poll the xdriver points Slow down the polls rate ,make sure it is under 2 polls per second,  If the issue still exist, please do the following steps Create a mirror point for each xdriver point,and fill the mirror point in AnnexPoint of Xdriver Point configuration tag Create an infinityfunction called PollFunction( as a example) in the BCX1 as below:           Arg 1 XdriverPoint Numeric count ,i,temp For count=1 to i Next count temp=xdriverPoint Return(temp)      4. Creat the poll program in BCX1 like below Numeric count,i,temp, Caller Line initial if caller is 0 then goto 1 line 1 i=200 temp=PollFunction(XdriverPoint1) DisplayPoint1=AnnexPoint1/rate1 goto 2 line 2 temp=PollFunction(XdriverPoint2) DisplayPoint2=AnnexPoint2/rate2 ... goto waitting line waitting Caller=1 goto Initial 5, Follow step4 , create another poll program to poll more xdriver points, change the sytax to caller=1,2....n in the Initial line, and change the sytax to caller=2,3,.....0 in the waitting line to assure there is only one program does poll xdriver point at the same time. After configure annexpoint, annexpoint will keep the good value and ingore the bad value.

Issue How many controllers and Workstations can Continuum systems support? Environment All Ethernet level controllers and Workstations. bCX, CX, NCII, ACX Cause Valid address ranges required Resolution Each "Network" (often called Continuum Network or Infinity Network) supports controllers with ACCNetID values of 1 to 190. No duplicate numbers are allowed on the same network Potentially the database supports up to 4 Million networks. Cyberstation workstations have ACCNetID's in the range 191 through 254 (maximum 64)

Issue If a Modbus IP server goes offline it will slow the polling of other operating servers, how can this be prevented? Environment Modbus TCP/IP X-Driver Cause When the Client Modbus IP XDriver polls points from a Server that is offline or not communicating it will time out slowing the polling of other online devices. Resolution Create a "Remote Device Status Point" (Function code 102) for each of the Servers on the system. This point will return a  value of 1 when the server is communicating, 0 when it is not connected. If a server is known to be offline or switched off this point can be set to a value of 2 to stop it polling that server for data. This allows the other servers to continue to be polled without any time out delays from every point on the offline server.

Issue Making changes in a personnel object from WebClient logs the user out with the error: Web.Client is currently unavailable, if the problem continues, contact your system administrator. Environment WebClient Cause The name of one or more areas attached to the personnel object contain non alpha numeric characters such as commas. Resolution Remove offending character from area's name.

Issue When PIV card is presented at the card reader a Bad Card Parity event is generated. Non PIV cards present no problem. Environment Card Access AC1 module PIV Format cards PIVReaderFormat Cause The controller was improperly configured for PIV cards. Resolution In this case the PIVReaderFormat system variable was not set. When the PIVReaderFormat is left blank the system defaults to FIPS_PIV_75 Bit for FIPS cards, if the FIPS reader is configured to send a diferent FIPS output such as FIPS_PIV_Full_FASC-N (200 bits) then the system will generate a bit count not supported error. Once the PIVReaderFormat system variable was set to the proper value the cards generated valid access events.

Issue How to reset a person's anti-passback violation. Environment CyberStation NetController ACX Cause Person tail gated in or out of an area in a site that uses anti-passback and the person is now unable to gain access. Resolution Set the person's current area to 'UnKnown' In the older personnel editor go to the Current Status tab and enter 'UnKnown' in the Current Area field. The Personnel Manager does not allow the reset but the current area of the person can be reset from the command line as follows... Root\CredentialFolder\AbeMeran = UnKnown or Root\CredentialFolder\AbeMeran = 0    (zero)

Issue When using a Modbus RTU block reads with a special function code incorrect data can be seen. Environment Modbus RTU X Driver All controller types that support X Drivers Cause The Modbus RTU X Driver does not support the use of block reads (annex points) for the special function codes. Resolution The Modbus RTU XDriver supports special function codes to convert various (Non Modbus standard) data formats for use in Continuum points. As detailed in the Modbus RTU X Driver manual (Param6) function codes, Parameter 6 should not be entered for Function codes 241 to 254. A separate X Driver point is required for each value to be read when using a special function code.

Issue The schedule works well for a long time, when save the schedule after edited, the error pops up ,"An attempt to write property has failed because not enough dynamic memory  space exists in the addressed BACnet Device" Environment Continuum BCX1 b3 devices Cause "Clear past events" is not checked in the schedule objects, the past events are kept in the controller and occupy a lot of dynamic space. Resolution Delete the schedule and  create an new one with the same configuration as  the original one Check "Clear past event " in the schedule objects to avoid the same issue happening again

Issue What are the cable specifications for wiring controller inputs to field devices. Environment Inputs Cable Sensors End devices Cause There is no specification for IO field wiring.   Resolution The line drop produced by cable resistance should be taken into account when choosing the wire gage for Input devices. It is good practice to run a shielded cable for analog inputs simply because it give you a way to drain off any externally induced voltage.

Issue Need to reference the outside temperature and humidity under another BCX1, but the value does not change as the referenced point changes. The program is running. The program code is as below: Line 1 Temp_Outside= NetworkA\BCX1_2\Temp_outside line E state=enabled goto 1 The result is : The value of Temp_outside does not change to equal the value of NetworkA\BCX1_2\Temp_outside Environment Continuum BCX1 B3 Cause A difference between the two BCX1s. The object type of the two points is not compatible. Resolution Correct the submask setting to make sure they have the same submask exactly Correct the object type to make sure they are compatible with each other

Issue Configured a digital input on SXW-UI16, with nothing connected to the input used a volts meter to measure the voltage between RET and the input, the volts meter reads 20.3. Why? Environment SXW-UI16 Other modules Cause This is normal, what is being measured is the voltage across the pull up resistor on the input circuitry. Resolution Any sensor attached to the input must be able to handle the voltage.

Issue Positioner output's override on 865-V always reads TRUE Environment 865-V Cause Documentation Resolution Unlike the 866-V, the 865-V DOES NOT support feedback on the position of its actuator output, the LCDState attribute of the output CAN NOT be used to learn the end positions of the actuator. As a result, the actuator output's override attribute on the 865-V always prints as TRUE since the firmware has no way of knowing the position of the actuator output.

Issue ERROR: Template or User record is either corrupt or not supported when sending templates to biometric readers Environment Bioscript V-Station integration Cause Enrollment reader's template type different from readers template types. Resolution Make sure the template type at the enrollment reader is the same as the template types in the other readers
