10.10.2 Manual production sequence
Introduction
You request the production data of different workpieces from the PLC and display this data
on the screen of the HMI device for inspection. You want to correct the transferred
production data in the recipe view or the recipe screen if necessary.
Procedure
A scanner connected to the PLC reads the barcode of a workpiece. The barcode names
correspond to the names in the recipe data record. Based on the barcode name, the PLC
can read the required recipe data record. The recipe data record is displayed for inspection
on the HMI device. You can now edit and save the recipe data record. Then transfer the
edited recipe data record to the PLC again.
The following figure shows the data flow schematically.
