Using Powerful GUI ProgramsDirectly Beside the command VIs, high-level VIs can be included direct- ly. A comprehensive selection of GUI programs is provided, such as a terminal application, interface selection routine, wave generator samples, 1D and 2D scan and align func-tions, joystick control, etc.

Quick Integration in LabVIEW

TM technology is avail-able under LabVIEW for these systems. HyperBit
TM allowsattaining position resolution many times better than the res- olution of the DAQ board used. Quick and Easy System Setup For commissioning a position-ing system, the special Con- figuration Setup VI is executed once. This VI gathers all neces- sary system information for LabVIEW, including:
Quick access to the full functionality Full Functionality of All PI GCS Controllers Available underLabVIEW High-Level & Low-Level VIs, Including GUI Programs Special VIs for Quick System Configuration Communication parameters Identical Control for Analog & Digital Controllers Connected controller(s) Open-Source Code of VIs Enables Customization Types & configurations of the connected stages/axes Preprogrammed Routines Accelerate Frequently Used Tasks Integrate & CustomizeConfiguration Setup VIs Comprehensive Help: Manual, Online Help, Sample Programs With its connectors, the Con-figuration Setup VI can be cus- tomized completely to meet the application requirements; it isincluded as initialization VI di-rectly in the LabVIEW applica- tion. After it has been run, all command VIs and high-level routines of the system can be used. One LabView Driver forDifferent Controllers The integration and control ofPI positioning systems under LabVIEW is greatly simplifiedby the provision of comprehen-sive LabVIEW libraries. The LabVIEW drivers support all GCS-capable controllers from PI, independent of the type of connected stage. Thus it is pos- sible to operate piezo, DC-motor, piezomotor, hybrid andhexapod controllers with one driver together in one applica- tion. controllers are absolutely uni-form in the VIs.This strongly reduces the effortrequired in case of controller upgrade or replacement. In addition, existing programs for different PI GCS controllers can be reused with greater ease.Very often adaptation consistssimply of replacing the con- troller-specific Configuration Setup VI.Any controller-specific func-tionality is, however, also fullyavailable under LabVIEW. One big advantage of the com-bination of the GCS command set and the VIs from PI is the identity in functionality of dif-ferent positioning systems.Identical functions in different Full Support for NI DAQBoards The same LabVIEW VIs that areavailable for PI digital con-trollers (e.g. set and read volt- ages and positions, velocity,etc.) can be used in conjunction with a National Instruments DAQ (data acquisition) board to operate positioning systemsbased on analog PI controllers.Furthermore, the patentedHyperbit
