4 IQ-SENSE
Note
Unused channels of the module must be deactivated otherwise the wire break
diagnosis will be reported.
Measurement type parameter: Deactivated
All the diagnoses are suppressed.

14.1.1 Group diagnosis parameter
If you enable group diagnosis, a queued diagnostic message is entered. See
Section 6.6.8 Channel-specific diagnosis.
14.1.2 Synchronization group parameter
Features
• Sensors of different modules of the 4 IQ-SENSE can affect one another with
scattered light, for example.
• To prevent this interference between adjacent sensors on different modules,
you can assign each module a separate synchronization group with this
parameter. Modules with different synchronization groups do not affect each
other.
• It is not possible for sensors on the same module to affect one another.
