A5E01078222-02 Edition 03.2009
Special features when making data entries at address connection AT, AR
when using PROFIBUS DP:
Input sequence:
"Channelname.Adressstage1.Addressstage 2"
Channel name
max. 8 characters
ASCII characters except "Point" and @
channel names of all transmit- and receive blocks, which access
the FM 458-1 DP at the interface X3 must be different (exception
for the "Multiple" data transfer mode).
the channel name has no special significance for PROFIBUS DP.
Input "." after the channel name
Address stage 1:
the slave PROFIBUS address is specified as address stage 1.
the slave PROFIBUS address may only assigned once for each
transmit- and receive channel.
value range: 0, 3 - 123
3...123: addressing external slaves.
Enter "." after address stage 1
Address stage 2:
consists of a maximum of 2 characters.
1st character: Byte order
"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. SIMATIC TDC).
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.
