Siemens D7-SYS - Using Transmit- and Receive Blocks

Communications configuring
System- and communication configuring D7-SYS - SIMADYN D 3-69
Edition 12.2003
CTS The configured name of the CS7 module (identical with the entry in the master program, actual:
D04) and the designation of the CS7 slot where the SS52 is located (X01, X02 or X03, actual:
X02) is specified at this initialization input.
MAA Just like all of the other bus nodes, the SS52 module has a station address. This must be
specified at this connector (a number between 1 and 123, actual: 4).
BDR The baud rate, which the SS52 uses on the bus, is set using this connector. This value must be
specified in a code:
0=9,6 kbaud ; 1=19,2 kbaud ; 2=93,75 kbaud ; 3=187,5 kbaud ; 4=500 kbaud ;
5=1,5 Mbaud ; 6=3 Mbaud ; 7=6 Mbaud ; 8=12 Mbaud ; (actual: 5).
SLA Initialization input, only for slave functionality:
0: SS52 operates as PROFIBUS master and/or slave. A COM PROFIBUS database must be
loaded.
1 or 2: SS52 operates as pure PROFIBUS slave without COM PROFIBUS database
1: Slave with either inputs or outputs,
2: Slave with inputs and outputs
(actual: 0)
LCC Initialization input for the time in which the SS52 module monitors the SIMADYN D host CPU:
<0: No monitoring
0...10: Monitoring time=1s (default)
>10: Monitoring time in 1/10 s
(actual: 0)
Table 3-31 I/O of the central PROFIBUS DP coupling block
3.5.3.7 Using transmit- and receive blocks
The function blocks of the communications utility, process data must be
configured for PROFIBUS DP.
The address connections AT and AR of those blocks, which access the
SS52 data interface, must have the following syntax (rules):
AT/AR- 'Channelname.Addressstage1.Adressstage2'
Channel name
• Must be unique, corresponding to the general communication rules
(the channel names of all transmit- and receive blocks, which access
the same SS52 communications module, must be different)
• It may consist of a maximum of 8 characters
• It has no special significance for PROFIBUS DP
Address stage 1
• The PROFIBUS address of the communication partner is specified in
this address stage.
• Using address 0, this channel goes to the slave and is called-up by
other bus masters.
• External slaves can be addressed using addresses 3..123.
