1. Because LabVIEW RT uses driver software on the host PC and in the RT Engine only certain driver software versions are compatible with LabVIEW RT The following table summarizes LabVIEW RT and driver software version compatibility LabVIEW Compatible RT NI DAQ Version Versions NI CAN FlexMotion NI Serial NI VISA NI 488 2 Se 6 5 2 6 6 5 1 2 6 7 or later 1 0 1 0 6 0 3 6 9 1 1 5 5 1 2 0 2 52 1 0 6 1 6 9 1 1 5 5 1 2 0 2 52 1 0 The following table summarizes the drivers that LabVIEW RT supports on the FieldPoint platform National Instruments Corporation LabVIEW RT IA Control FieldPoint VI Version Environment NI Serial Manager 5 1 5 1 2 6 0 3 4 0 2 0 1 0 6 1 4 0 2 0 1 0 3 LabVIEW Real Time Release Notes Examples Refer to the VIs in examples rt for examples of real time programming and control applications The LabVIEW RT examples are grouped into the following VI libraries RT Communication 11b e RT Control 7030 llb RT Control 1llb RT Tutorial llb e RT Watchdog PXI 8156B llb RT Communication RT Communication examples demonstrate how to communicate data between RT Engine VIs and host PC VIs You can use the VI Server and TCP IP examples with the RT Engine on RT Series DAQ devices or networked RT Series devices You can use the shared memory examples only with the RT Engi2. Development System on the host computer However if you disconnect the RT Development System from the RT Engine and subsequently reconnect it you must reset the properties for them to take effect on the reopened front panel The same applies to embedded remote panels 5 LabVIEW Real Time Release Notes e TheRT Series PXI Controller cannot use the internal SCXI control bus ina PXI MXI III system without modification to the PXISYS INI file on the RT Series PXI Controller This issue only affects users who connect the PXI chassis to the downstream side of the MXI III bridge and want to use the internal SCXI bus to control the SCXI modules Refer to ni com support for more information about the RT Series PXI Controller e Time critical LabVIEW RT applications take priority over real time operating system tasks Because the real time operating system maintains the date and time information the Get Date Time in Seconds function might return inaccurate values Timing functions such as Tick Count ms are not affected by this problem e PXI floppy disk utilities created using LabVIEW RT 5 1 2 are not compatible with LabVIEW RT 6 1 You must use MAX to create new PXI utility disks compatible with LabVIEW RT 6 1 PXI floppy disks created in LabVIEW RT 6 0 3 are supported in LabVIEW RT 6 1 e LabVIEW RT supports only ISA based GPIB controllers LabVIEW RT does not support PXI controllers with on board PCI based GPIB interfaces However certain
3. PXI controllers with ISA based on board GPIB interfaces such as the PXI 8156B are supported in LabVIEW RT e The General Error Handler VI changed in LabVIEW 6 1 The correct files are copied automatically to an RT engine at bootup If you are using custom errors place the files in C NI RT SYSTEM ERRORS on the RT engine This directory also contains specific language folders you can use if you want to localize your custom errors To conform to the 8 3 filename structure name the error with a err extension rather than errors txt Two configuration tokens are available for error files Set RTDownloadErrors TRUE in the embedded system s NI RT INI file to cause the RT engine to request a list of available errors the first time it is targeted This request only occurs if the RT engine cannot find any error files locally such as an RT engine that does not have disk I O The host machine searches for all available error files and transfers the parsed error data back to the RT target If you want to specify the actual filenames that the host system should parse you can create a list using the RTDownloadErrorList token in the RT Engine s NI RT INI file Refer to LabVIEW Help for more information about the changes to the General Error Handler VI and using error code files LabVIEW Real Time Release Notes 6 ni com
