Step 1 - Set the "Archive measured variable" option
Activate the "Archive measured variable" option for each instance parameter to be recorded
as a measured value. You have the following options:
● Using BATCH interface blocks:
– at the IEPAR blocks for the parameter QACT_VAL or
– in the BATCH configuration dialog at the "Batch types" object.
● When using SFC types: The "Archive" column (S7_archive attribute) of the characteristics
for the setpoint is activated for the SFC type.
Note
For SFC types, this setting can only be made directly at the SFC type. All batch types of
the SFC type are read-only in the BATCH configuration dialog.
Convenient setting in the process object view
The setting for "Archive measured variable" can also be made in the process object view. To
do this open the "Parameters" tab. The settings for several parameters can be conveniently
made in the "Archive" column.
Possible settings
● No archiving
● Archiving (= short-term)
● Long-term archiving (= long-term)
Inheritance with SFC Types -> SFC Instances
Note
If an instance from the SFC type is created in the CFC chart, the setting of the S7_archive
attribute at SFC type is passed to the instance. This means that if the setpoint for the archiving
is labeled (Para(i)_AO) at the SFC type, this setting is automatically active in all SFC instances.
You should avoid changing this setting at the SFC instances (in contrast to the SFC type)
because synchronization is only made in the BATCH configuration dialog with the SFC types
for operation, function and process tag types (not with SFC instances). This may lead to
validation errors and therefore errors in the compilation.

Note
These two settings have the same effect. Using the Generate function in the BATCH
configuration dialog, the changes at the instances are entered in the batch types or by
entering changes in the BATCH configuration dialog the changes are transferred to all
instances in the CFC.
