LabVIEW EPICS I/O Servers National Centre for Nuclear Research, Poland LabVIEW EPICS I/O Servers LabVIEW Datalogging and Supervisory Control (DSC) Module and the LabVIEW Real-Time Module act as Channel Access (CA) clients through I/O servers. 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. 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).
