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).
At IND=5 res. IND=6 the parameters of the indicator word are also
in the data source.
Parameter type : Pointer
Convenient range : DB, M, A, E

Block size
During the boot process the stations agree about the block size
(size of the data blocks) by means of SYNCHRON.
A high block size = high data throughput but longer run-times and
higher cycle load.
A small block size = lower data throughput but shorter run-times of
the blocks.
These block sizes are available:
Value Block size Value Block size
0 Default (64Byte) 4 128Byte
1 16Byte 5 256Byte
2 32Byte 6 512Byte
3 64Byte 255 512Byte
Parameter type : Integer
Convenient range : 0 ... 255
Error indication at parameterization defects
This "BYTE" (output, marker) is set if the block detects a parame-
terization error, e.g. interface (plug-in) not detected or a non valid
parameterization of QUANF/ZANF.
Parameter type : Byte
Convenient range : AB 0 ... AB127, MB 0...MB 255
QANF/ZANF
