14.39 MES Interface Library
MES interface library function enables to link the CNC internal data with the database of information system (manufacturing
execution system).
For example, it becomes possible to carry out the production management, traceability, etc. from the registered information by
registering the information at the time of machining completion, alarm occurrence or user's option to the database as shown
by the figure below. Also it is possible to operate the registered data in the database from the CNC.
Conventionally, data were acquired from an external computer (information system) to CNC by monitoring constantly.
However, using MES interface library function, it is possible to connect the database directly without a communication
gateway and to communicate the data between the CNC and database at a necessary timing.
This function is supported on CNC, and the function range is from obtaining the information at the time of machining
completion, alarm occurrence or user's option to sending it to database. Screen application of database and external
computer must be prepared by user side.
