1. A method of controlling a field device in a control system, the method comprising:
- providing a memory device including at least one proscribed period;
monitoring, via a processor, the field device;
detecting, via a processor, an occurrence of a diagnostic event associated with the field device;
formulating, via a processor, a diagnostic check of the field device in response to the occurrence of the diagnostic event;
determining, via a processor, whether execution of the diagnostic check will occur during the at least one proscribed period;
executing, via a processor, the diagnostic check if the diagnostic check will not occur during the at least one proscribed period; and
rescheduling, via a processor, execution of the diagnostic check if the diagnostic check will occur during the at least one proscribed period.

Abstract
A diagnostic system and method for a field device in a process plant is provided. The diagnostic apparatus includes a processor operatively connected to the field device and a calendar having a proscribed period stored in memory. A diagnostic check is executed on the field device if an occurrence of a diagnostic event is detected and execution of the diagnostic check does not coincide with the proscribed period.

1. A method of controlling a field device in a control system, the method comprising:
-
providing a memory device including at least one proscribed period; monitoring, via a processor, the field device; detecting, via a processor, an occurrence of a diagnostic event associated with the field device; formulating, via a processor, a diagnostic check of the field device in response to the occurrence of the diagnostic event; determining, via a processor, whether execution of the diagnostic check will occur during the at least one proscribed period; executing, via a processor, the diagnostic check if the diagnostic check will not occur during the at least one proscribed period; and rescheduling, via a processor, execution of the diagnostic check if the diagnostic check will occur during the at least one proscribed period. - View Dependent Claims (2, 3, 4, 5, 6)

7. A diagnostic apparatus for a control system having a controller operatively connected to a field device, the diagnostic apparatus comprising:
-
a processor operatively connected to the field device to detect an occurrence of a diagnostic event; a memory operatively connected to the processor; a calendar stored in the memory, the calendar including a proscribed period when execution of a diagnostic check is prohibited; and
,a diagnostic module stored in the memory, wherein the processor executes the diagnostic module if the occurrence of the diagnostic event is detected and execution of the diagnostic module does not coincide with the proscribed period, and the processor reschedules execution of the diagnostic module if the occurrence of the diagnostic event is detected and execution of the diagnostic module does coincide with the proscribed period. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. A tangible non-transitory computer-readable medium having instructions stored there on that, when executed by one or more processors, cause the one or more processors to:
-
monitor an occurrence of a diagnostic event associated with a field device; detect the occurrence of the diagnostic event; formulate an action responsive to the occurrence of the diagnostic event; determine whether execution of the action will occur during a proscribed period; execute the action if the execution of the action will not occur during the proscribed period; and
,reschedule the action if the execution of the action will occur during the proscribed period. - View Dependent Claims (17)
