摘要： Methods and apparatus to upgrade and provide control redundancy in process plants are disclosed. An example disclosed method to upgrade software for a control device of a process control system comprises instantiating a replacement component of the software, copying state data from an existing component to the replacement component, and changing the replacement component to an active mode when a first state of the replacement component matches a second state of the existing component.

摘要： Process control systems for operating process plants are disclosed herein. The process control systems include control modules that are decoupled from the I/O architecture of the process plants using signal objects or generic shadow blocks. This decoupling is effected by using the signal objects or generic shadow blocks to manage at least part of the communication between the control modules and the field devices. Signal objects may convert between protocols used by control modules and field devices, thus decoupling the control modules from the I/O architecture. Generic shadow blocks may be automatically configured to mimic the operation of field devices within a controller executing the control modules, thus partially decoupling the control modules from the I/O architecture by using the shadow blocks to manage communication between the control modules and the field devices.

摘要： Example methods and apparatus to manage module run sequences in a process control environment are disclosed. A disclosed example method includes receiving a module including a plurality of function blocks, receiving an indication of a subset of the plurality of function blocks, and receiving an indication of a first sequence of execution for the subset, wherein the first sequence of execution is different than a second sequence of execution associated with the module. The example method also includes associating the subset with a run sequence identifier, and associating the run sequence identifier with a trigger condition.

摘要： Example methods and systems to verify a communication path between a field device and a process controller in a process control system are disclosed. A disclosed example method includes transmitting via a first wireless communication path to a first portion of a process control system associated with one of the field device or the process controller, a command signal from a verification controller. In response to receiving the command signal in the first portion of the process control system, transmitting a verification signal via a first wired communication path from the first portion of the process control system to a second portion of the process control system associated with the other one of the field device or the process controller. Then, in response to receiving the verification signal in the second portion of the process control system, transmitting a reception signal via a second wireless communication path from the second portion of the process control system to the verification controller and in response to receiving the verification signal in the verification controller, verifying the communication path between the field device and the process controller.
