Output assignments for a command from the PDP master to the SLK:
Table 11: Output assignments for command-oriented data exchange
Output Bit Name
address
0 7 Tbit
6 - 0 CMD
1 Data0
2 Data1
3 Data2
4 Data3
5 Data4
6 Data5
7 Data6
8 Data7
The data area is organized such that the high byte is in the low address (Motorola
format), e.g., the "no. data bytes" is divided as follows:
Data4 (low output address)
"No. data bytes" high byte
Input assignments for SLK reply to PDP master

Unassigned bytes in event-oriented data exchange transmit 0.
Description
Toggle bit, has to be inverted for each command
Command, see Chapter 7.2.1 "Profibus commands" for cod-
ing
SLK address SLK address
No. data bytes No. data bytes
Data byte 1
Data byte 2, etc.
Data5 (higher output address)
"No. data bytes" low byte
Description
Toggle bit, has to have the same value as the corresponding
command
"Mirrored" command code
Information on whether the command was correct
(value = 0) or not (value > 0)
