With IND = 0 you fix that the pointer QANF / ZANF shows directly to the source res. desti-
nation data. The following table shows the possible QANF / ZANF parameters at the
direct parameterization:
QTYP/ZTYP Data in DB Data in MB Data in OB Process
image of the outputs
Data in IB Process
image of the inputs
Pointer:
Example:
P#DBa.DBX b.0 BYTE
CP#DB10.DBX 0.0 BYTE 8
P#M b.0 BYTE cP#M
5.0 BYTE 10
P#A b.0 BYTE cP#A
0.0 BYTE 2
P#E b.0 BYTE cP#E
20.0 BYTE 1

P#DBa
"a" means the DB-No., from
where the source data is fetched
or where to the destination data is
transferred.
P#M
The data is stored in a
MB.
P#A
The data is stored in the
output byte.
P#E
The data is stored in the
input byte.
Valid range for
"a"

Indirect addressing means that QANF / ZANF points to a memory area where the
addresses of the source res. destination areas and the indicator word are stored. In this
context you may either define one area for data source, destination and indicator word
(IND = 1) or each, data source, data destination and the indicator word, get an area of
their own (IND = 2). The following table shows the possible QANF / ZANF parameters for
indirect parameterization:
QTYP/ZTYP
IND = 1 IND = 2
Definition Indirect addressing for source or destination
parameters. The source or destination parameters
are stored in a DB.
QANF/ZANF:
Indirect addressing for source and destination parameters.
The source and destination parameters are stored in a DB in
a sequential order.
QANF/ZANF:
DW +0 Data type source DW +0 Data type source Description data source

vant
