4.1 Activating the data transfer between the PLC and NCK
Function
Data transfer from/to NCK with the following properties can be started via the PLC:
● Data transfer from the hard disk to or from the NCK (workpiece directory, part program,
etc.) using job lists.
● The "Job list" function is used in HMI-Advanced to process part programs - e.g. loading,
unloading, selecting or executing from the hard disk.
By means of the interface between the PLC and HMI in DB19, the PLC issues jobs to the
HMI that initiate a data transfer between the HMI (PCU hard disk) and NCK.
