pvAccessCPP: ca provider

2018.10.05

Editors:

  • Marty Kraimer

ca is a channel provider ca that is implemented as part of pvAccessCPP.

It uses the channel access network protocol to communicate with a server, i. e. the network protocol that has been used to communicate with EPICS IOCs since 1990.

A description of ca is provided in caProvider

Provider pva is another way to connect to a DBRecord, But this only works if the IOC has qsrv installed. qsrv, which is provided with pva2pva, has full support for communicating with a DBRecord. The only advantage of ca is that it does require any changes to an existing IOC.
