| 20140077623 | SPIKE TRAP LOGIC TO PREVENT UNNEEDED INTERRUPTION OF INDUSTRIAL PROCESSES - Techniques are disclosed for preventing unneeded interruption of industrial processes. Spike trap logic used to delay the occurrence of a trip or interlock when a registered signal exceeds a threshold for a minimum period of time. Doing so prevents trips or interlocks from occurring for transient or intermittent signals, which may be the result of poor sensor readings, poor configuration, or actual, but brief, spikes that should not result in a tripped process or machine. That is, rather than simply tripping—or interlocking—when a trip signal is initially observed, the spike trap logic introduces a delay between when a trip signal is received and when an interlock or trip event actually happens. If the signal remains high for delay period, a trip occurs. Otherwise, the trip signal is considered an intermittent or transient spike and does not result in a trip. | 03-20-2014 |
