S5-95U, SINEC L2 System Description
Procedure for Assigning Parameters in DB1 and the S5-95U
A default DB1 is integrated in the operating system of the S5-95U programmable controller.
DB1 contains default values for parameters, including those for data exchange by means of
SINEC L2.
Load the default DB1 in your programmer (function: transfer; source: PC; destination:
FD (PG)).
Look for the SINEC L2 parameter block. The block ID is "SL2:".
The SINEC L2 parameter block is enclosed in comment characters (#). The programmable
controller cannot interpret the SL2: parameter block in this form ( Figure 1.6). Overwrite the
comment characters that appear before the block ID (SL2:) and after the last SINEC L2
parameter with a blank.
Enter the parameters according to your specifications (for basic parameters and parameters for
the desired communications services, see chapters 3, 4, 6, 7 and 8) in one coherent block
after the block ID.
Make sure you follow the general rules for assigning parameters. Refer to the S5-90U/S5-95U
Programmable Controller System Manual, section 9.1.4.
Transfer the changed DB1 to the S5-95U. The default DB1 is overwritten with the changed
DB1.
If you now switch from STOP to RUN mode, the S5-95U accepts the new parameters. If the BF
LED lights up ( Table 3-1), you must switch from POWER OFF to POWER ON (mode selector at
RUN and backup battery inserted) on the S5-95U to transfer DB 1.
Refer to Appendix A for the following information:
• The procedure for reading the DB1 parameter assignment error code and its interpretation
• The explanations to the SET, ST, SDT 1, and SDT 2 parameters. (It is not absolutely
necessary to know the meaning of these parameters.)
• The procedure for setting (calculating) the target rotation time (TRT) depending on the baud
rate (BDR)
