EQU-1: Equipment Instance Identifier (EI) 01479

Definition: This field identifies the equipment. This is the identifier from an institution's master list of equipment. The <namespace ID> identifies the institution.

The Equipment Instance Identifier shall be unique, meaning that the “Entity Identifier” component shall be unique within the Namespace ID that should accommodate hierarchical representation of equipment (recursive hierarchy like in "Russian dolls", e.g., a sub-module embedded in a module assembled in a system being a member of a cluster).

If this attribute repeats, all instances must represent the same device.

EQU-2: Event Date/Time (DTM) 01322

Definition: This field is the date/time that the event (e.g., state transition, issuing of command, finishing of command execution) occurred.

EQU-3: Equipment State (CWE) 01323

Definition: This field identifies the status that the equipment was in at the time that the transaction was initiated. Refer to HL7 Table 0365 – Equipment State in Chapter 2C, Code Tables, for valid values. The Equipment State is required in the ESU message and is optional otherwise.

EQU-4: Local/Remote Control State (CWE) 01324

Definition: This field identifies the current state of control associated with the equipment. An equipment can either work autonomously ('Local' control state) or it can be controlled by another system, e.g., LAS computer ('Remote' control state). Refer to HL7 Table 0366 – Local/Remote Control State in Chapter 2C, Code Tables, for valid values.

EQU-5: Alert Level (CWE) 01325

Definition: This field identifies the highest level of the alert state (e.g., highest alert severity) that is associated with the indicated equipment (e.g., processing event, inventory event, QC event). Refer to HL7 Table 0367 – Alert Level in Chapter 2C, Code Tables, for valid values.

EQU-6: Expected date/time of the next status change (DTM) 03487

Definition: This field is the predicted date/time of the next equipment status change (e.g. from “maintenance” back to “normal operation”).
