EACmessage code: what kind of message this is - MSH-9.2
U07trigger event: what happened in the real world: automated equipment command - MSH-9.3
EAC_U07message structure: which segments to expect, and in what order
How to use these specifications explains MSH-9 in full, with a worked example.
Message structures
EAC takes 1 structure.
EAC_U07: Automated Equipment Command
Sent when one thing happens: U07: Automated Equipment Command.
You must always send: MSH, EQU, ECD. Everything else is optional, or required only inside a group you chose to send.
| Segment | Name | OPT | Cardinality |
|---|---|---|---|
| MSH | Message Header | R | 1..1 |
| SFT | Software Segment | O | 0..* |
| EQU | Equipment Detail | R | 1..1 |
| COMMAND | a group of 4 segments, repeated together | R | 1..* |
| ECD | Equipment Command Detail | R | 1..1 |
| TQ1 | Timing/quantity ? | O | 0..1 |
| SPECIMEN_CONTAINER | a group of 2 segments, repeated together | O | 0..1 |
| SACin SPECIMEN_CONTAINER | Specimen Container Detail | R | 1..1 |
| SPMin SPECIMEN_CONTAINER | Specimen | O | 0..* |
| CNS | Clear Notification | O | 0..1 |
| ROL | Role Detail | O | 0..1 |
R inside a group means required of that group. Send the group and you must include that segment; leave the group out and it never appears. This structure has 2 such groups: COMMAND, SPECIMEN_CONTAINER.
