Description
The p4p library is a Python wrapper for the C++ pvxs library allowing Python developers to access client functionality to put, get, and monitor pvAccess PVs. Server functionality allows the creation of PVs and implements the structure of the most commonly used Normative Types (e.g. NTScalar) and their fields (e.g. alarm, control, etc.). To facilitate the transition to EPICS underway at the ISIS Neutron and Muon Source accelerators, an implementation of the logic of the Normative Type fields and a subset of other IOC functionality such as CALC records has been developed. We present our uses of this work and highlight parts which may be applicable to other facilities interested in using Python.
