2.1 Programming PLC Functions

2.1.1 Activating Data Transfer from PLC

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 lists" function in HMI Advanced enables the full range of part program
handling operations, such as loading, unloading, selecting or executing, from
the hard disk.
References relating to job lists:
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 (hard disk) and NCK.
