Note!
Information about the valid range can be found at the technical data of your
CPU.
ORG identifier 05h-07h
CPU area PB ZB TB
ORG identifier 05h 06h 07h
Description Source/destination data
from/into peripheral
modules. Input module for
source data, output module
for destination data.
Source/destination data
from/into counter cells.
Source/destination data
from/into timer cells.
ERW identifier
(DBNO)
irrelevant irrelevant irrelevant
Start address
Significance
PB-No., from where the data
can be retrieved or where it
is saved.
ZB-No., from where the data
can be retrieved or where it
is saved.
TB-No., from where the data
can be retrieved or where it
is saved.
Length
Significance
Length of the
source/destination data
block in bytes.
Length of the
source/destination data
block in words
(counter cell = 1 word).
Length of the
source/destination data
block in words
(counter cell = 1 word).
ORG identifier 81h-FFh
To transfer data blocks of the number range 256 ... 32768 you may use the
ORG identifier 81h-FFh.
For the setting of a DB No. >255 needs a length of one word, the DBNO
new
is assembled from the content of the ORG identifier and the DBNO.
DBNO
new
is created as word as follows:
DBNO
new
High-Byte Low-Byte
1 X X X X X X X X X X X X X X X
ORG identifier (0XXXXXXX)
DBNO (XXXXXXXX)
If the highest bit of the ORG identifier
is set, the Low-Byte of DBNO
new
is
defined via DBNO and the High-Byte of DBNO
new
via ORG identifier, where
the highest bit of the ORG identifier is eliminated.
The following formula illustrates this:
DBNO
new
=256 x (ORG-identifier AND 7Fh) + DBNO
