Cannot collect data from one detector when other Ethernet detectors in the system are powered-off using Empower - WKB4846

SYMPTOMS

• Only need to collect data from ECD detector (2424), 2489 is powered-off. Creating new Instrument methods and new system did not work. System configuration has 2489, e-2695, and 2424 (all Ethernet.)

ENVIRONMENT

• Empower 3 Feature Release 2.
• Enterprise, client server.
• Ethernet-controlled Waters instruments (2489, e-2695 and 2424).

CAUSE

This is a defect reported under PCS #45505 titled: Do not turn off Ethernet instruments within an Empower instrument method.

• Do not turn off Ethernet device from within the Empower instrument method, as this can cause several issues during the run. If a device is not needed in the chromatographic system, this device should not be included when the system is created.

FIX or WORKAROUND

1. Recreate a chromatographic system in Empower using only the required instruments needed to collect data.
2. Create a separate instrument method in Empower with only the required instruments.
