General Information Regarding BUEP-E and BUEP19E
The protocol-specific parameters parameterize the data traffic through
BUEP-E for AST and PST. Below, the parameters are going to be explained
separately.
Parameter
Word
PW4 Type of command
Example
This parameter determines the command type of the job. Two types can be
distinguished:
D E (45 ) Input in the AST
H
D A (41 ) Output from the AST
H
The direction of the jobs always refers to the AST, so that an output job
(41  A) transmits data from the AST to the PST and an input job (45
H
transmits data from the PST to the AST.
A job which is started with a differing command type results in the abortion of
the job with a corresponding error message.
The low byte of the parameter describes the type of operand of the job. Ac-
cording to which AST command code is applicable, eight different operand
types can be used:
Code [hex] Data Type
00 Byte
01 Word
02 Double word
03 Quad word
04 Byte mask
05 Word mask
06 Double word mask
07 Quad word mask
When selecting the operands, please check if they are supported by the
PST.
