Indicator word (double word)
n Address of the indicator double word in the user memory where the processing of the
order specified under ANR is shown.
– Parameter type: Double word
– Convenient range: DW or MW; use either DW and DW+1 or MW and MW+2
The value DW refers to the data block opened before the incoming call or to the
directly specified DB.
Kind of parameterization (direct, indirect)
n This parameter defines the kind of data on which the pointer QANF points.
– 0: QANF points directly to the initial data of the source res. destination data.
– 1: the pointer QANF/ZANF points to a memory cell, from where on the source res.
destination data are defined (indirect).
– 2: the pointer QANF/ZANF points to a memory area where the source res. desti-
nation information lies (indirect).
– 5: the pointer QANF/ZANF points to a memory cell, from where on the source res.
destination data and parameters of the indicator word are defined (indirect).
– 6: the pointer QANF/ZANF points to a memory area where the source res. desti-
nation data and parameters of the indicator word are laying (indirect).
– Parameter type: Integer
– Convenient entries: 0, 1, 2, 5, 6
Please regard, that at IND = 5 res. IND = 6, the parameter ANZW is
ignored!
Relative start address of the data source res. destination and at IND = 5 res. IND = 6 of
the indicator word.
n This parameter of the type "pointer" (Any-Pointer) allows you fix the relative starting
address and the type of the data source (at SEND) res. the data destination (at
RECEIVE).
n At IND = 5 res. IND = 6 the parameters of the indicator word are also in the data
source.

P#E 0.0 BYTE 8
P#A 0.0 BYTE 10
Block size
n During the boot process the stations agree about the block size (size of the data
blocks) by means of SYNCHRON.
n A high block size = high data throughput but longer run-times and higher cycle load.
n A small block size = lower data throughput but shorter run-times of the blocks.
These block sizes are available:
ANZW
IND
QANF/ZANF
