Fig. 3−246 Writing data to a memory location
1. Apply a value to STORE3−IN−POS. STORE3−SEL−IN shows the memory location which is to be
written to (in Fig. 3−246 memory location 11).
2. Via a LOW−HIGH edge at STORE3−LOAD−IN−POS, the value is written to the memory location.
3. Afterwards the pointer STORE3−SEL−IN automatically is increased by one (in Fig. 3−246 from
memory location 11 to 12).
Reading data from the memory location
l STORE3−MODE = LOW
– The functions "Write data to the memory location" and "Read data from the memory
location" are carried out independently of each other.
– In this mode, a flying splice of the cutting lengths can be achieved.

Fig. 3−247 Reading data independently of writing data
1. STORE3−SEL−OUT indicates the memory location, the value of which is to be transmitted to
STORE3−PHOUT.
2. Via a LOW−HIGH edge at STORE3−STORE−PHOUT, the value is read from the memory
location.
3. Afterwards the pointer STORE3−SEL−OUT automatically is increased by one (in Fig. 3−247
from memory location 7 to 8).
l STORE3−MODE = HIGH
– The functions "Write data to the memory location" and "Read data from the memory" are
combined.
