What is a Lua Script Used For In A Power PDU?

Lua is a basic programming language designed for use in embedded applications. It is a cross-platform language as the interpreter is compiled bytecode written in ANSI C and has a relatively simple C API. Lua is used for user scripts and supports a limited set of variables including Boolean values (true/false), numbers, strings and tables. In a compatible smart power device, a Lua script can be used to control power outlets and IP/LAN connectivity. A Lua script can run continuously or when trigged by an event to power sockets ON/OFF, send emails, receive and send ‘ping’ messages, download and parse XML/JSON files over http.
