FAQ

Q: Do I always have to define one sorting column per table?

A: Yes, you must always define exactly one sorting column, otherwise no data will be read from this table and no data can be entered.

Q: Is it possible to display the connection ids or datapoint ids in the Common Configurator?

A: No, at the moment it is not possible to display data in the Common Configurator during runtime.

Q: Is it possible to sort by multiple columns?

A: No, currently it is only possible to sort by exactly one column.

Q: Must a complete table always be configured for reading?

A: No, not all columns of a table have to be configured if they are not to be read out. As a minimum requirement only the sorting column must be defined to be able to start a read operation.

Q: Is it possible to read from columns that are not defined as "not null"?

A: Yes, it is possible to read from columns which are not defined as "not null", but it is not possible to guarantee a correct function if there is no value in the column.
