A method of logging process data in a PLC controlled equipment is disclosed. Sections of a PLC application code comprise tasks configured to execute program functions at specific execution rates. Each of the tasks comprise program functions having dedicated memory areas assigned as tags, and each data entry of the process data comprises a tag value and an associated process value. The method comprises receiving process data from the PLC application code, assigning process values to threads of a thread pool, and receiving, for each of the threads, in a respective data table associated with each of the threads, the tag- and process values of the received process data, and determining a hash code for each of the tags according to a hash function of the respective data table for arranging the tag values and the associated process values in the respective data table according to said hash code.

The invention relates to a method of operating an apparatus for applying drinking straws to packaging containers. The method comprises the steps of performing a first portion of a motion cycle by moving at least one applicator arm from an application position to a leaving position, said first portion being equal for successive packaging containers. The method also comprises performing a second portion of the motion cycle by moving the at least one applicator arm from the leaving position back to the application position, said second portion being adjusted to fit the pitch between successive packaging containers. The invention also relates to an apparatus operated by the method.

The invention relates to a method of operating an apparatus for applying drinking straws to packaging containers. The method comprises the step of moving a drinking straw carrier from an application position to the leaving position, in a packaging container moving direction, maintaining a velocity in that direction being equal to a constant velocity of a first conveyor. The invention also relates to an apparatus being operated according to the method.

The invention relates to a method of operating an apparatus for applying drinking straws to packaging containers. The method comprises the steps of performing a motion cycle of a drive means for bringing at least one drinking straw into a picking position, and adapting said motion cycle such that, at the point when an application device picks the drinking straw at the picking position, the acceleration of the drive means is substantially zero and the velocity of the drive means is kept at a set point velocity. The invention also relates to an apparatus being operated according to the method.
