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).
Note You need to install the LabVIEW Real-Time Module to publish CompactRIO I/O Variables (IOVs).
