S5-100U Integrated Blocks and Their Functions
9 Integrated Blocks and Their Functions
9.1 Assigning Internal Functions to DB1, for CPU 103 Version 8MA03 and
Higher
You can program the following CPU functions:
• Using the integral real-time clock (see chapter 12)
• Exchanging data via SINEC L1 (see chapter 13)
• Changing polling interval for time-controlled program processing (OB 13) (see chapter 7)
• Assigning system parameters (see section 9.1.3)
• Setting the address for the parameter error code (see section 9.1.2)
To assign parameters to these functions, you must configure data block 1 (DB1).
9.1.1 Configuration and Default Settings for DB1
To make it easier for you to assign parameters, data block 1 is already integrated in the CPU with
default parameters
. After performing an overall reset, you can load the default DB1 from the
programmable controller into your programmer and display it on the screen (see Figure 9-1). The
character string “DB1” must remain before the parameter blocks and be followed by at least one
filler (such as a blank space or a comma).

This preset DB1 has one parameter block for each function. Each parameter block begins with a
block ID (shown in Figure 9-1 in the shaded background). The block ID is followed by a colon. The
individual parameters for each function are contained in these parameter blocks.
Each parameter block begins with a block ID followed by a colon. This colon must be followed by
at least one filler (such as a blank space or a comma). A semicolon must be at the end of each
parameter block with at least one filler between the semicolon and the next block ID.
