Installing 575 System Hardware SIMATIC 545/555/575 System Manual
4.10 Configuring the CPU
Before installing the 575–2105 or 575–2106 CPU board, you must configure
the dipswitch on the 575 CPU board. The configuration options override any
dipswitch settings that you may have made on an HSIO annex card or a
PROFIBUS-DP annex card.
Figure 4-15 shows the position of the configuration dipswitch on the
575–2105 and 575–2106 CPU boards. Table 4-3 lists the dipswitch
configuration options.

CPUs
If you are using a 575–2104 CPU, you must configure the dipswitch located
on the HSIO or PROFIBUS-DP annex card. Refer to Section 4.11.
Figure 4-16 shows the location of the dipswitch on the 575–2126 annex card.
Figure 4-17 shows the location of the dipswitch on the 505–CP5434–DP
annex card. Table 4-3 lists the dipswitch configuration options.
NOTE: All switches have the same meaning for both annex cards, except for
switches 1–2. For the 575–2126 annex card, these switches must be in the
correct position (On) or the 575 CPU will not be able to communicate with
the remote bases. Table 4-3 identifies the correct switch settings for each
annex card.
