Abstract: Implementations relate to storing, in alarms database for a process automation system, an association of an alarm configuration file to a function block identifier of a function block that corresponds to the alarm configuration file. Some implementations relate to a node transmitting, via a process automation network, an alarm configuration request that includes the function block identifier and receiving, in response to the request and via the network, the alarm configuration file. The node can include the function block identifier in the alarm configuration request based on the corresponding function block being executed by the node and/or being utilized in alarm monitoring by the node. Some implementations additionally or alternatively relate to receiving the alarm configuration request, and identifying the alarm configuration file based on it being stored, in the alarms database, in association with the function block identifier of the alarm configuration request.

Abstract: Implementations are described herein for provisioning a device such as a DCN with configuration data for operation on a process automation network using an “out-of-band” communication channel. In various implementations, a temporary out-of-band communication channel may be established between a first and second DCNs. The out-of-band communication channel may be distinct from a process automation network through which the first DCN is to be communicatively coupled with other process automation nodes of a process automation system. Provisioning data may be transmitted from the second DCN to the first DCN over the temporary out-of-band communication channel. The provisioning data may include: information technology (IT) configuration data and operational technology (OT) configuration data. Subsequent to the transmitting, the temporary out-of-band communication channel may be closed.

Abstract: Implementations are described herein for commissioning a distributed control node (DCN) to a process automation network. In various implementations, one or more messages transmitted on the process automation network by the DCN announcing that the DCN has joined the process automation network may be detected. Based on the one or more messages, one or more operational technology (OT) capabilities of the DCN may be determined. Based on the one or more OT capabilities, the DCN may be commissioned to the process automation network, e.g., by configuring the DCN to cooperate with one or more other process automation nodes on the process automation network to implement an at least partially automated process.

Abstract: Implementations are described herein for determining whether to allow a cross-platform process automation client to write to an I/O channel controlled by a cross-platform process automation server. In various implementations, the cross-platform process automation client transmits a request to access a writer account of the cross-platform process automation server to the cross-platform process automation server, to write to the I/O channel. In response to receiving the request to access the writer account, the cross-platform process automation server determines whether the writer account is available. If the writer account is determined as being unavailable (e.g., currently being used by another cross-platform process automation client), the cross-platform process automation server can deny the request from the cross-platform process automation client to access the writer account, and/or provide the cross-platform process automation client access to a reader account.

Abstract: Implementations are described herein for commissioning a device such as a distributed control node (DCN) for operation with a process automation system (PAS) using a portable setup device (PSD) and an “out-of-band” communication channel. In various implementations, static information conveyed by a passive data store of the DCN may be used to establish an out-of-band communication channel between the DCN and PSD. The out-of-band communication channel may be distinct from a process automation network through which the DCN is to be communicatively coupled with other process automation nodes of the PAS. The DCN may be commissioned to the process automation system by exchanging operational technology (OT) data between the DCN and the PSD via the out-of-band communication channel to enable the DCN to cooperate with one or more of the other process automation nodes on the process automation network to implement an at least partially automated process.

Abstract: Implementations are described herein for leveraging an “out-of-band” communication channel between nodes of a process automation system. In various implementations, an out-of-band communication channel may be established between two or more process automation nodes of a process automation system. The out-of-band communication channel may be outside of a process automation network through which the two or more process automation nodes are communicatively coupled with other process automation nodes of the process automation system. The two or more process automation nodes may cooperate with one or more of the other process automation nodes to implement an at least partially automated process. One or more characteristics of the process automation system may be monitored, and based on the monitoring, traffic may be selectively diverted from the process automation network to the out-of-band communication channel.

Abstract: An Open Platform Communications (OPC) Unified Architecture (UA) server includes: a storage that stores a configuration file written in a compiled programming language and in which an interpreter is embedded; a transceiver that receives, from an OPC UA client, an execution request to execute a calculation defined in the configuration file; and a processor that executes the calculation using the interpreter.

Abstract: A system that operates using Open Platform Communications (OPC) Unified Architecture (UA) includes: a redundant server set including a first OPC UA server and a second OPC UA server; an OPC UA client that designates an endpoint Uniform Resource Locator (URL) to communicate with the redundant server set; and a load balancer (LB) connected between the redundant server set and the OPC UA client. The OPC UA client sends a request for connection to the endpoint URL. The first OPC UA server is an active server. The second OPC UA server is a standby server. The LB proxies the connection to the first OPC UA server. The end point ULR is different from a URL of each of the first OPC UA server and the second OPC UA server.
