"1": Standard PROFIBUS setting
The data are transferred in the ”Motorola format” (most significant
byte before the least significant byte).
”0”: Exception setting
The data are transferred in the ”Intel format” (least significant byte
before the most significant byte). This setting can be used for
communication partners whose internal data administration uses
the Intel format (e. g. SIMADYN D).
− 2nd character: Optional, only receiver
"R":
The access is realized as second master which reads data. ”R” can
only be entered for receive channels. (”Shared input”)
If a 2nd character is not specified, then the slave can be accessed
as parameterizing master.
• AT- 'Setpoint.25.1'
− the channel with the name setpoint transmits data to a slave with
the PROFIBUS address 25.
• AR- 'RECEIVE.117.0'
− the channel with the RECEIVE name receives data from a slave
with PROFIBUS address 117. As an exception, data are
transferred in the Intel format.
• AR- 'Input.33.1R'
− the channel with the name input receives data from a slave with
PROFIBUS address 33 as (second) master which reads data.
• AT- 'Slavelst.0.1'

DP master.
