Since we started developing a number of "pure" pvAccess servers,
users/developers have been asking how to do state machines that connect to
them.
Is there any experience or plan to add support for pvAccess to the
SNL/Sequencer?
I have no concrete plans. There are basically two reasons:
(1) I can't see how to reconcile the SNL data model with PVA. In CA you
have the basic primitive types which are mapped to the basic SNL types;
or arrays of those which are similarly mapped to SNL arrays; and then a
fixed set of meta data on top of that. PVA provides a richer set of data
types that does not map easily to a language that is, give or take, a
variant of C. Also, meta data is not as uniform in PVA as in CA. Even if
support is restricted to Normative Types, I am not sure we can map all
of them to SNL types in a reasonably useful way.
