Off-line diagnosis system
First Claim
1. A process-control diagnosis system, the system comprising:
- a field instrument for use in a process-control system, the field instrument comprising memory of a predetermined capacity and a data transmitter, the field instrument operable to;
perform a diagnosis function for at least two zones of a signal input range that is divided into a plurality of zones,store diagnosis results for a first zone in a memory location,transmit the diagnosis results for the first zone, andstore diagnosis results for a second zone in the memory location, wherein the combined size of the diagnosis results for the first zone and of the diagnosis results for the second zone is larger than the diagnosis-results capacity of the memory location.

Abstract
Process control systems may include one or more diagnostic systems and/or processes. In particular implementations, a diagnostic system and process for a field instrument may include the ability to divide a signal input range into a plurality of zones with respect to an input axis or a time axis, measure input response characteristics for a zone with the field instrument, and store measurement data points for the zone in memory of the field instrument. The diagnostic system and process may also include the ability to transmit the measurement data points for the zone to a host application and, while transmitting the measurement data points for the zone, measure input response characteristics for a second zone with the field instrument.
