Abstract A previous paper described an upgrade to EPICS enabling client side tools at LANSCE to receive subscription updates filtered selectively to match a logical configuration of LANSCE beam gates, as specified dynamically by control room application programs. This update paper will examine evolving enhancements enabling Lua-language based data acquisition processing subscription update filters, specified by snippets of Lua-language source-code embedded within the EPICS channel-name’s postfix. We will discuss the generalized utility of this approach across a wide range of data acquisition applications, projects, and platforms; the performance and robustness of our production implementation; and our operational experience with the software at LANSCE.
