1. EPICS-LabVIEW Interfaces PANDA Collaboration Meeting December 2009 Holger Brand GSI – EE/KS

2. Dec 7th, 2009EPICS-LabVIEW Interfaces; H.Brand@gsi.de Outline Overview LabVIEW™ Datalogging and Supervisory Control Module –CA Client –CA Server LabVIEW-DIM-Interface EPICS-DIM-Interface (→Vortrag P.Zumbruch)

3. Dec 7th, 2009EPICS-LabVIEW Interfaces; H.Brand@gsi.de Overview Up-to-know we know about those existing solutions LabVIEW® DIM Interface ⇔ EPICS - DIM Interface by GSI LabVIEW® Shared Memory Interface to EPICS IOC by SNS –Working beta release since years –LabVIEW 7.1 with hard coded absolute pathes LabVIEW® ActiveX CA by Kay Uwe Kasimir, ORNL –Deprecated and no longer supported LabVIEW® Data Logging and Supervisory Control Module, NI –CA Client is working –CA Server is, at least for me, not yet working.

6. Dec 7th, 2009EPICS-LabVIEW Interfaces; H.Brand@gsi.de EPICS Client I/O Servers (DSC Module) LabVIEW DSC Module acts as a Channel Access (CA) client. Use the EPICS Client I/O servers to monitor and update process variables (PVs) that an input/output controller (IOC) or Channel Access server (CAS) publishes using the CA network protocol. You can create an EPICS Client I/O server to monitor and update the value of a PV that exists on an IOC or CAS.create

8. Dec 7th, 2009EPICS-LabVIEW Interfaces; H.Brand@gsi.de EPICS Server I/O Servers (DSC Module or RT Module) With EPICS Server I/O servers, LabVIEW acts as a server that uses the Channel Access (CA) network protocol. Use EPICS Server I/O servers to publish shared variables by using the CA network protocol. An EPICS Server I/O server is a Channel Access server (CAS). You can create an EPICS Server I/O server to publish local and remote shared variables and CompactRIO I/O variables (IOVs).create When you publish a shared variable, the EPICS Server I/O server creates a process variable (PV) for this shared variable and binds this shared variable to this PV. The type of this PV corresponds to the data type of this shared variable. After you deploy the processes that contain this shared variable and this EPICS Server I/O server, the EPICS Server I/O server publishes this PV to the EPICS network by using the CA network protocol.deploy
