Where path scheduling occurs in the instrument
Bind valve positions, reagent sources and target plate positions in the control system, including shared-resource interlocks. After an anomaly, retain sample identity and completed steps to prevent misdelivery or duplicate dispensing.
Confirm valve position together with reagent source and target well. Restart programs should preserve sample identity and completed-step records to prevent duplicate additions.
Product responsibilities in this operation
Valves control the current source or destination; the associated drive performs metering or transfer. Port connections, actual positioning and shared-segment renewal must match the operation.
For this Biofoundry construction and screening task, confirm task state, sample/vessel identity, concurrent resources, interlocks and recovery.
Organize the sequence by actual architecture
- In fixed-path configurations, map reagent sources, valve ports, target plate positions and construction tasks to each other. Identify shared resources and permitted occupancy.
- Confirm resources and valve position before drive operation. On source changes, refresh shared sections and record actual receipt.
- After an anomaly, retain reagent, well and completed-step records. Handle undelivered, partially delivered and completed states separately to prevent misdelivery and duplicate dispensing.
Define operating conditions for this task
| To define | Details |
|---|---|
| Actual operating conditions | Task state, sample or vessel identity, concurrent resources, interlocks and restart |
| Acceptance target | Test concurrent operation, limiting states and complete fault recovery; verify that identities, cumulative quantities and records match actual actions |
| Fault localization | Resource conflicts, communication loss or mismatched identities can cause delivery to the wrong destination or repeated dosing. |

Validate operation results at the receiver
Cover concurrency, boundary states and complete recovery after faults. Check that identity, cumulative volume and records match actual operations.
Assess per-well delivery, identity traceability and construct-development or screening results together.
Locate abnormalities and restore the next operation
Resource conflicts, communication interruptions or identity mismatches can cause misdelivery or duplicate dispensing.
Stop the affected branches and recover using execution records.
High throughput and multiple channels do not establish valid experimental results. See laboratory automation for shared workstation architecture.
