Use in PLC

The datalog is managed by means of the control variable (GS_DATALOG_PAR type) declared by the user in the PLC program.The single data items in the structure are available as Datalog control interface.The sampling variable is independent of the control structure and can be any variable controlled by the system (for example: a PLC variable or an I/O or FIELD).Sampling is done only at minimum instants of 1 second. To check actual sampling, you can check when the COUNTER field changes value.
