Data logger commands from the system

When a data logger stop command is given, the recording is stopped from the system. The subsequent recording is enabled by a Restart trigger
command. The same applies to the operator panel, as illustrated in par. 16.4.2.6.

Example of data logger operation

The following figure shows an example of how a trigger works, the data logger's function, the effect of the stopping delay and of the
restart and subsequent stop commands on the data saving procedure.
