摘要： Example removable security modules for use with process control devices and related methods are disclosed. An example removable security module includes a body configured to be removably coupled to the process control device and a memory disposed in the body with a shared secret stored in the memory. The example removable security module also includes a processing unit disposed in the body, coupled to the memory and configured to read information from the process control device, compare the information to the shared secret and authenticate the process control device based on the comparison.

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： A distributed process control equipment ownership arbitration system and method for arbitrating equipment ownership conflicts are disclosed. Individual control modules representing various process control entities within a process control system define a plurality of lists or queues for storing equipment arbitration information. Requests by one process control entity to acquire ownership over another process control entity are represented by an arbitration token that represents the ownership relationship sought by the acquiring process control entity. Copies of the arbitration token are communicated between the respective control modules and stored in the various arbitration queues defined by the control modules, depending on the status of the acquisition request. Upon receiving an acquisition request from another process control entity, the control module associated with the targeted process control entity decides whether the targeted process control entity is available to be acquired by the requesting control entity based on arbitration rules that are embedded within the control module itself. Once the targeted process control entity has been acquired by another process control entity it may not be acquired by any other process control entity until it has been released by the acquiring process control entity.

摘要： Apparatus and methods for intrusion protection in safety instrumented process control systems are disclosed. An example method of protecting a safety instrumented system includes receiving legitimate information from a component of a process control system wherein the legitimate information is intended for delivery to a safety instrumented system, determining if a signature at least substantially matches the legitimate information, and preventing the legitimate information from reaching the safety instrumented system when it is determined that the signature at least substantially matches the legitimate information.

摘要： Methods and apparatus to apply multiple trip limits to a device in a process control system are disclosed. An example method involves monitoring a value of a parameter associated with the operation of the device and receiving an input indicative of an operational state of the device, where a first input indicates a first operational state and a second input indicates a second operational state. If the first input is received, comparing via a function block the value of the parameter to a first trip limit, and if the second input is received, comparing via the function block the value of the parameter to a second trip limit, and implementing a response based on the comparison.

摘要： A control system, a safety system, etc., within a process plant may each use one or more state machine function blocks that can be easily integrated into a function block diagram programming environment. Such a state machine function block may include one or more inputs, which may cause a state machine implemented by the state machine function block to change states. The state machine function block may determine a next state to which it is to transition based, at least in part, on data indicative of the next state to which to transition, if any. The configuration data may be retrieved from a database based on the current state of the state machine and at least one of the inputs. The state machine function block may also include one or more outputs that are generated based on the state of the state machine.
