The invention relates to a WIA-PA (Wireless Networks for Industrial Automation-Process Automation)/full-interconnection manufacturing network information service adaptor and a realization method thereof. The adaptor can access WIA-PA and devices thereof to a full-interconnection manufacturing network which takes an IPv6 protocol as an addressing method and an XMPP protocol as a transmitting method. According to the realization method thereof, in the adaptor, user application objects of the WIA-PA are converted into an XML description format following the definition of the full-interconnection network; in an application sub-layer, C/S, P/S and R/S communication modes of the WIA-PA are converted into a transmitting mode corresponding to the XMPP; and in a network layer, the internal network addresses of the WIA-PA are mapped into standard IPv6 addresses, each device of the WIA-PA has a virtual IPv6 address, and an external network can address the devices of the WIA-PA through the IPv6 addresses. The adaptor realized by the invention is easy to integrate with the existing network, and the open interconnection between the WIA-PA and the internet is effectively realized.
