In order to facilitate reuse of an NC program for operation that has been executed in the past, this control device for a machine tool that drives the machine tool by executing an NC program is provided with: a first program storage unit that identifies an NC program for machining using a program name or program number and stores said program; a second program storage unit that stores an NC program for operation each time an operator executes an NC program for operation that is input manually; and a display unit that lists a plurality of NC programs for operation stored in the second program storage unit and displays said programs.

An update apparatus is provided. The update apparatus may comprise: a grouping unit configured to group a plurality of robots using a network; and an update unit configured to update the plurality of grouped robots through the network.

Unique systems, methods, techniques and apparatuses of industrial control system file synchronization are disclosed herein. One exemplary embodiment is an industrial control system comprising an industrial controller and a first and second computing device. The second computing device includes a second non-transitory memory device structured to store both a file set and synchronization instructions, and includes a processing device configured to execute the synchronization instructions so as to classify a subset of files from the second file set by identifying files transferred to the second computing device from the industrial controller, classify a sub-subset of files from the subset of file using a set of synchronization rules, classify a set of synchronization files from the sub-subset of files, and transfer the set of synchronization files from the second computing device to the first computing device.

A control system is mounted with a function of transmitting/receiving a plurality of types of data together. If a plurality of data acquisition requests are made, the system creates a single grouping request by grouping the individual data acquisition requests. The grouping request is transmitted by a single communication session, and a device having received the grouping request acquires a plurality of pieces of data in response to the plurality of data acquisition requests included in the received request, creates the result of grouping of the acquired data, and transmits the result as a response to the grouping request.

Computer numerical control (CNC) machines execute a process automatically unless a condition occurs that triggers one or more alarms that terminate the process. Accordingly, CNC laser cutting post-process inspection is usually non-existent or minimal. However, with CNC laser welding it is more common for a visual inspection or automated inspection to be performed to verify that the process was completed. Similar issues occur when single piece parts are required in addition to which executing an offline inspection requires additional complexity in re-working any piece part. Accordingly, embodiments of the invention provide enterprises and facilities employing CNC laser cutting/welding systems with a means to overcome these limitations. Further, providing intuitive user interfaces allows the user to perform tasks directly through a touch screen interface they are viewing the work piece/piece-parts upon.

In a numerical controller including a DNC operation unit, an automatic operation execution unit includes a buffering completion checking result holding unit for checking whether a portion of a machining program to be buffered includes a buffering point, an execution checking result holding unit for checking whether a portion of the machining program to be executed includes a buffering point, a comparison unit for comparing the buffering completion checking result holding unit with the execution checking result holding unit, and an execution unit for performing any one of continuation, suspension, and resumption of the automatic operation based on a result of the comparison.
