OverviewOverview
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.

• EPICS Client
• EPICS Server
• Used to bind CA-PVs to LV Shared Variables
• LabVIEW is also OPC-Server

EPICS Client I/O Servers (DSC Module)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.

EPICS Server I/O Servers EPICS Server I/O Servers (DSC Module or RT Module)(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).• 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.
