Communications interface option for CNC systems
NUM Corporation’s NUMConnect is a communication interface option that complies with the open MT Connect interoperability standard. MTConnect is an open, royalty-free communications standard designed to improve the use of real-data in manufacturing industries. NUMConnect is designed to be fitted to new or existing systems and simplify the integration of CNC machine tools with third-party manufacturing management software. The NUMConnect software interface is comprised of two main components: an MTConnect adapter and an MTConnect compliant information provider or lightweight webserver known as an "Agent." The Adapter collects data from the CNC system, associates it with defined MTConnect data items, filters out any duplicates and then pushes the data to the Agent, where it is held in a buffer store until overwritten by fresh information. To help minimize response times, MTConnect does not require the establishment of a formal data transfer session, and under normal use there are no log-on or log-off sequences. When the Agent receives a request for information from any client application software, it transfers the appropriate data over the network, using HTTP. The system is inherently secure; MTConnect is a read-only standard designed to facilitate the retrieval of data from manufacturing equipment; it does not control or instruct a CNC machine tool to take action.
