Setting Parameters In Db1, For Cpu 103 And Higher - Siemens S5-100U User Manual

S5-100U

13.2.2 Setting Parameters in DB1, for CPU 103 and Higher

Set the parameters in DB1 as follows:
1. Display the default DB1 on the programmer (Transfer function, source: PC, target: FD (PG)
- A default DB1 is integrated into the programmable controller's operating system; it contains
default parameters for the data exchange via SINEC L1.
2. Look for the SINEC L1 parameter block with the block ID "SL1:" for the PG/OP/SINEC L1 port.
3. Overwrite the comment character (#) with a space.
SL1:
SLN 1
...
...
PGN 1
4. Edit the default parameters according to your requirements. Do not change the syntax.
Example:
The S5-100U participates in the SINEC L1 network as a slave with the slave number 2.
- Send Mailbox (SF) in DB2 beginning with data word 0
- Receive Mailbox (EF) in DB2 beginning with data word 10
- Coordination Byte Send (KBS) is flag byte 0 (MB0)
- Coordination Byte Receive (KBE) is flag byte 2 (MB2)
- Programmer bus number (PGN) is 1.
Table 13-3 shows how to change default parameters for the example given above and which
parameter settings are permitted.
5. Transfer the changed DB1 to the programmable controller. The default DB1 is overwritten.
If you now go from STOP to RUN or from Power OFF to Power ON (with a battery inserted), the
programmable controller accepts the changed parameters and stores them in the system data area.
