A apparatus having a control network and a first controller comprising a microprocessor configured to support communication functions, control execution functions, I/O functions, and control network interface functions, a second controller configured as a redundant partner to the first controller, and an I/O link and I/O modules.

Process control device having modern architecture and legacy compatibility

A method includes receiving information associated with one or more first alarms in a first control system and generating a graphical user interface containing information associated with a second control system. The method also includes presenting, in the graphical user interface, at least a portion of the information associated with the one or more first alarms. The method further includes receiving, from a user via the graphical user interface, an invocation of an alarm management function. In addition, the method includes performing the invoked alarm management function using at least one of the one or more first alarms. The alarm management function could include acknowledging, shelving, and/or filtering the at least one of the one or more first alarms. The first control system may not support acknowledging, shelving, and filtering of alarms, while the second control system may support acknowledging, shelving, and filtering of alarms.

Unified status and alarm management for operations, monitoring, and maintenance of legacy and modern control systems from common user interface

An apparatus, method, and non-transitory machine-readable medium provide for accurate automatic determination of alarm-operator action linkage for operator assessment and alarm guidance using custom graphics and control charts. The apparatus includes a memory and a processor operably connected to the memory. The processor receives process control system data regarding a field device in an industrial process control and automation system; extracts information from the process control system data; generates a tuple based on the extracted information; and performs a rectifying operation in the industrial process control and automation system based on the generated tuple of the field device.

System and method for accurate automatic determination of 'alarm-operator action' linkage for operator assessment and alarm guidance using custom graphics and control charts

An apparatus includes a computing architecture having multiple memories including a first memory and a second memory. The multiple memories are configured to store multiple copies of a memory image including a first copy and a second copy, where the memory image contains instructions to be executed by the computing architecture and data to be used by the computing architecture. The computing architecture can be configured to perform multiple functions including a first function and a second function. The first memory can be positioned in the computing architecture so that the first copy of the memory image is located in a first position that is more efficient for the first function. The second memory can be positioned in the computing architecture so that the second copy of the memory image is located in a second position that is more efficient for the second function.

Replication of memory image for efficient simultaneous uses

A method includes translating at least one application source code file associated with a legacy controller in a distributed control system to instructions executable by a controller simulation computing device, wherein the legacy controller is associated with a legacy operating system and the controller simulation computing device is associated with a second operating system different from the legacy operating system. The method also includes simulating operation of the legacy controller using the instructions and an emulation of the legacy operating system in the controller simulation computing device. The method further includes determining configuration data for the legacy controller during the simulated operation of the legacy controller. In addition, the method includes saving the configuration data to a configuration data file.

System and method for legacy level 1 controller virtualization

A method includes receiving at least one source code file associated with a legacy hardware platform, the at least one source code file being part of a software migration from the legacy hardware platform to a target hardware platform. The method also includes identifying one or more absolute memory addresses of the legacy hardware platform included in the at least one source code file. The method further includes for each of the one or more absolute memory addresses, including an address remapping function in an assembly language instruction block associated with the target hardware platform.

System and method for facilitating dynamic remapping of absolute addresses during software migration

A method includes transmitting, by a first processing device, a signal to a second relay processing device. The signal includes a message for the second relay processing device to transmit a read command and/or a write command to an I/O device that is not accessible by the first processing device. The method also includes receiving, by the first processing device, an indication that the second relay processing device has transmitted the read command and/or the write command to the I/O device.

Relay mechanism to facilitate processor communication with inaccessible input/output (I/O) device

An apparatus includes a first interface configured to communicate over a first industrial process control network using a first protocol. The apparatus also includes a second interface configured to communicate over a second industrial process control network using a second protocol. The apparatus further includes a third interface configured to communicate with at least one supervisory device over a third network. In addition, the apparatus includes at least one processing device configured to provide concurrent access for the at least one supervisory device to process control devices coupled to the first and second industrial process control networks during a migration of process control devices that use the first protocol to process control devices that use the second protocol.
