If data from a single monitoring task totally occupies the Display

Memory, then this data can be stored in Background Memory

provided that no data is already stored there. The data will occupy

only one location of Background Memory and fill all available storage

space. Therefore, it will not be possible to store any data from any

new monitoring task in Background Memory unless the data already

stored there is first deleted (see

section 9.3.3

).

To illustrate the variable size of each location let us suppose that the

following monitoring tasks are performed:

Task No. 1:

The data collected in Display Memory occupies 20%

of the total capacity of the Display Memory. The data

can be stored in Background Memory provided that

the data already stored there occupies less than

80% of the total capacity of the Background

Memory. However, let us suppose that the

Background Memory is empty and that we STORE

the data from this monitoring task in location 1 of

Background Memory. This means that Background

Memory is now 20% full (see

Fig.9.5

).

Task No. 2:

The collected data occupies 30% of the total capacity

of the Display Memory. Let us suppose that we

STORE the data in location 2 of Background

Memory. This means that Background Memory is

now 50% full (see

Fig.9.5

).

Task No. 3:

The data occupies 40% of the total capacity of the

Display Memory. Let us suppose that we STORE the

data from this task in location 3 of Background

Memory. Background Memory is now 90% full (see

Fig.9.5

).

Task No. 4:

The data occupies 10% of the total capacity of the

Display Memory. Let us suppose that we STORE the

data from this task in the Background Memory – let

us say it is stored in location 4. Background Memory

is now 100% full (see

Fig.9.5

).

The Background Memory has now been filled-up by the data from the

four monitoring tasks described above, even though location nos. 5 –

10 (inclusive) have not been used. The user will not be able to

STORE any more data in Background Memory because there is no

space available for it. Data in Background Memory can, however, be

deleted to make space for the storage of new measurement results

(see

section 9.3.3

).
