A device may receive a hash table that includes lists of protocol detectors, wherein the hash table is generated based on historical process data identifying potential process variables associated with an industrial control system. The device may receive a packet identifying potential process variables associated with the industrial control system, and may extract, from the packet, packet data identifying a source address, a destination address, a port, and a transport protocol. The device may compare the packet data with data in the hash table to identify a set of lists of protocol detectors, and may process the packet data, with the set of lists of protocol detectors, to determine a matching protocol, no matching protocol, or a potential matching protocol for the packet. The device may perform one or more actions based on determining the matching protocol, no matching protocol, or the potential matching protocol for the packet.

A method in which a monitoring unit allocated to a communication device checks, based on a name resolution protocol, whether a second communication network address allocated to the first communication device becomes valid in order to set up an uninterrupted communication connection to the communication device that is allocated to an industrial automation system, where in cases of an allocation of a new valid communication network address and an existing communication connection, the monitoring unit initiates a set-up of an additional communication connection using the new communication network address.

A field device includes components to communicate with a control and/or asset management system of a process control system or with other field devices using any of several different communication protocols such as several different internet protocol (IP) protocols. This architecture allows for a single version of a field device to be provided in automation or plant control systems that use any of these communication protocols, thus saving on inventory and product development costs. Moreover, the multi-protocol field device or a system using the multi-protocol field device can manage the asset (read and write parameterized data from and to the asset) using one protocol while at the same time communicating real-time process/factory automation information using a second and different protocol. Moreover, the field device may be able to communicate to other devices including other field devices and host devices using both of these protocols or other protocols for different purposes.

Techniques for generating user interfaces (UIs) for field devices on a host device are described. A field device driver installed on the host device transmits a request for UI configuration to a field device. The field device includes a plurality of sets of UI parameters associated with configuration of the UI. The field device is configured to select a set of UI parameters from the plurality of sets of UI parameters based on application information provided to the field device. The field device driver receives the set of UI parameters from the field device in response to the request. Based on the set of UI parameters, the host device configures and generates the UI.

An execution plan segment of an execution plan can be received at a control unit of a computer numerically controlled machine from a general purpose computer. The execution plan segment can define operations for causing movement of a moveable head of the computer numerically controlled machine to deliver electromagnetic energy to effect a change in a material within an interior space of the computer numerically controlled machine. The execution plan segment can include a predefined safe pausing point from which the execution plan can be restarted while minimizing a difference in appearance of a finished work-product relative to if a pause and restart are not necessary. Operations of the computer numerically controlled machine can be commenced only after determining that the execution plan segment has been received up to and including the predefined safe pausing point by the computer numerically controlled machine.

A moveable head of a computer numerically controlled machine may deliver electromagnetic energy sufficient to cause a first change in a material at least partially contained within an interior space of the CNC machine. A feature of the material may be imaged using at least one camera present inside the interior space to update a position of the material, and the moveable head may be aligned to deliver electromagnetic energy sufficient to cause a second change in the material such that the second change is positioned on the material consistent with the first change and with an intended final appearance of the material. Methods, systems, and article of manufacture are described.

A computer numerically controlled machine may include a movable head configured to deliver electromagnetic energy to a part of a working area in which the movable head may be commanded to cause delivery of the electromagnetic energy. The interior space may be defined by a housing and may include an openable barrier that attenuates transmission of light between the interior space and an exterior of the computer numerically controlled machine when the openable barrier is in a closed position. The computer numerically controlled machine may include an interlock that prevents emission of the electromagnetic energy when detecting that the openable barrier is not in the closed position. The commanding may result in the computer numerically controlled machine executing operations of a motion plan for causing movement of the movable head to deliver the electromagnetic energy to effect a change in a material at least partially contained within the interior space.
