The terminal block defines a first receptacle to receive a first circuit and a second receptacle to receive a second circuit. The terminal block includes an integral relay. The integral relay includes a first contact and a second contact. The first and second contacts are externally accessible relative to the terminal block. The integral relay further includes a first switch and a second switch. The first and second switches are electrically coupled between the first and second contacts. The first and second switches are respectively movable between corresponding open and closed positions. The first and second switches are independently testable to verify the respective operability of the first switch and the second switch.

摘要： Methods and apparatus to detect root causes of alarm patterns in process control systems are disclosed. An example method includes retrieving process control data generated in a process control system during a historical period of time. The process control data includes alarm data associated with alarms activated during the historical period of time. The example method also includes generating an alarm activation timeline for the historical period of time. The alarm activation timeline includes icons representative of the alarms to visually represent a temporal relationship of activation of the alarms, where one of the icons is representative of an alarm that is no longer active. The example method further includes storing the alarm activation timeline in a database.
