Relative start address of the data source res. destination and at IND=5 res.
IND=6 of the indicator word.
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
Example:
P#DB10.DBX0.0 BYTE 16
P#M0.0 BYTE 10
P#E 0.0 BYTE 8
P#A 0.0 BYTE 10
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:

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.
