I am currently looking at EPICSv4. I am interested in better understanding pvAccess which can transfer structured data (pvData). I understand the pvAccess can use EPICSv3 CA to access database entries in the IOC. But how to I implement and enforce the use of the pvAccess Client Layer? How do I integrate a pvAccess Server in the IOC?
It is my understanding that IOC programming will not chance with EPICSv4, is this correct?
