Preassignments When Saving Plc Data - Siemens SINUMERIK 840D sl Commissioning Manual

Time of data backup
Experience has shown that the following times can be recommended for carrying out data
backups:
● Following commissioning
● After changing machine-specific settings
● After service, e.g., after replacement of a hardware component, software upgrade, etc.
● Before activation of memory-configuring machine data. A warning prompting you to back

Preassignments when saving PLC data

Introduction
When creating a series-commissioning file that contains PLC data, the PLC image that is
saved during this process is dependent on the status of the PLC at the time of creation.
Depending on the status of the PLC, the following PLC images result:
● Original image
● Instantaneous image
● Inconsistent image
Operating sequence for original image
The original image of the PLC is represented by the PLC-data state immediately after
loading the S7 project into the PLC.
1. Set the PLC to the operating status STOP.
2. Load the appropriate S7 project into the PLC using SIMATIC Manager STEP 7.
3. Create a series-commissioning file with PLC data.
4. Set the PLC to the RUN operating status.
Operating sequences for instantaneous image
If you cannot create an original image, you can save an instantaneous image as an
alternative.
1. Set the PLC to the operating status STOP.
2. Archive PLC data.
