6.3 Register for the Mapping
In the following Memory registers you have the option to define the
data mapping of the Data Broker for the input and output areas of the
interfaces.
For each consumer (target register) there is a register area, in which
all sources ("producers") are listed from which it obtains data. The
data of the source areas is stored in the target area continuously in
succession ("consumer") as well as the entries for this consumer. A
maximum of 8 entries per consumer are possible. Each entry
occupies 2 Memory Register. In the first Memory Register you can
specify the base number of the Memory Register from which the data
is copied. In the second Memory Register you determine the number
of values you want to copy. Here, you can also exchange the High
Byte and Low Byte (swap).
In the event of an invalid mapping, an error message flag is set in the
status register 0x0002.
In section " Data Broker [
}
20]" we will explain how a mapping works.
You will also find an example of a mapping.
