Effect of ONLINE changes
• Modified system variables come into effect instantaneously.
• Changes in configuration data come into effect according to the setting in the
"Effectiveness" column.
- "instantaneous"
Values are confirmed and are applied by pressing RETURN or clicking
"enable.".
- "restart"
Values do not come into effect until the next restart of the technological
object with the technology function"MC_Reset.".
- "download"
Values can not be changed in online mode. Change to OFFLINE mode,
make your changes and then download the technology delta to the PLC.
• Changes to system variables and configuration data are retained when the
Technology CPU changes from STOP to RUN.
• Changes to system variables and configuration data are non-retentive, i.e. they
are lost after power has been cycled.
In the Navigator, select the technology, then select Target device > Copy
current data to ROM to save your changes in configuration data to retentive
memory.
To store the values permanently in your project data, you need to apply your
changes in OFFLINE mode, save and compile the technology data and
download these to the destination device. You can also upload the deltas to
the project data of the technology by executing the PLC > Upload >
Configuration data to PG. Next, select Technology > Save and compile all
to save and compile the technology.
Effect of OFFLINE changes
• OFFLINE changes affect only the technology project data. To apply these
changes to the Technology CPU, select Technology > Save and compile all
to save and compile the data, then select PLC > Download > Technology to
PLC to download these data to the PLC.
