6.1 CA80xx: How to start Measurement, Calibration and Cleaning
This chapter applies only to the Liquiline CA80xx analyzer.
The actions “Measurement”, “Calibration” and “Cleaning” can be controlled by Modbus while the analyzer is
in the operation mode “Fieldbus”.
The operation mode “Fieldbus” can be activated either by Modbus or the device menu.
Important:
A change of the operation mode does not interrupt a pending action. A new action can only be started
after the pending action has finished or is aborted.
The following state diagram describes the operation mode and state transitions.
