Methods, apparatus, systems, and articles of manufacture are disclosed to augment process control with a virtual assistant. An example apparatus includes at least one processor and memory storing instructions that, when executed, cause the at least one processor to determine a process control context based on a request for information associated with a field device of a process control system, the process control context based on a configuration of the process control system, identify a topic included in the request, the topic corresponding to the field device based on the process control context, map the topic to an action to be executed by the field device, generate a command to direct the field device to execute the action based on the mapping, and transmit the command to the field device to execute the action.

Systems and methods for providing external bus protection for programmable logic devices (PLDs) are disclosed. An example system includes a programmable I/O bus configured to interface with a user device over an external bus interface coupled to a PLD; a bus protection circuit arrangement integrated with the programmable I/O interface and configured to provide I/O bus supply voltage protection for the programmable I/O interface; and a bus protection control signal generator. The bus protection control signal generator generates a default bus protection control signal for the bus protection circuit arrangement of the PLD prior to completion of a power ramp performed by the user device; an intermediate bus protection control signal for the PLD prior to completion of loading a PLD configuration into a PLD fabric of the PLD; and an operational bus protection control signal for the PLD.

A control system includes one or a plurality of functional units, and a control device for exchanging communication data transmitted circularly among the functional units. The control device selects, in accordance with an instruction from a user or in accordance with a predetermined condition, one transfer system of a first transfer system in which a computation processing unit transfers the communication data and a second transfer system in which a DMA controller transfers the communication data.

An edge controller may be used for obtaining device data from one or more local devices at a local facility and to provide a representation of at least some of the device data to a remote server. The edge controller may include a network communication port, a cellular communication port and a device communication port. A controller is operatively coupled to the network communication port, the cellular communication port and the device communication port and is configured to receive configuration information and to install the received configuration information on the edge controller. The installed configuration information configures the controller to obtain the device data from the one or more local devices and to send a representation of at least some of the device data to the remote server.
