7.1.2 Protocol-Specific Parameters
The protocol-specific parameters parameterize the data traffic through
BUEP-E for AST and PST. Below, the parameters are going to be explained
separately.

Type of Command
This parameter determines the command type of the job. Two types can be
distinguished:
D E(45
H
) Input in the AST
D A(41
H
) Output from the AST
The direction of the jobs always refers to the AST, so that an output job
(41
H
 A) transmits data from the AST to the PST and an input job (45
H
 E)
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.
Type of Operand
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 Number in Bytes
00 Byte 1
01 Word 2
02 Double word 4
03 Quad word 8
04 Byte mask 2
05 Word mask 4
06 Double word mask 8
07 Quad word mask 16
When selecting the operands, please check if they are supported by the
PST.
