BUEP19E Protocol 7-3
7.3.1.1 Command Type Parameter
This parameter indicates the types of commands for the job. There are
two types of commands:
‘E’(45H) Input into the RST
‘A’ (41H) Output from the RST
The direction of the jobs always refers to the RST, i.e., an output job (41H
--> ‘A’) transfers data from the RST to the PST and an input job (45H -->
‘E’) transfers data from the PST to the RST.
If a job is started with a deviating type of command, the job is terminated
and a corresponding fault message is returned.
7.3.1.2 Operand Type Parameter
The LOW byte of the parameter specifies the types of operands for the
job. Depending on the RST command code, eight different types of ope-
rands can be used:
Code Data type Number in bytes
00H Byte 1
01H Word 2
02H Double word 4
03H Quad word 8
04H Byte mask 2
05H Word mask 4
06H Double word mask 8
07H Quad word mask 16

When selecting the operands, check whether they are also supported by
the PST.
