Installing 575 System Hardware SIMATIC 545/555/575 System Manual

4.11 Installing a Remote I/O Annex Card (Optional)

There are two ways to connect your 575 CPU to remote I/O:

• Use a PPX:575–2126 remote I/O annex card to connect the 575 CPU to

Series 505 remote I/O by means of the Series 505 remote I/O channel.

• Alternatively, you can use a PPX:505–CP5434–DP PROFIBUS-DP

annex card to connect the 575 CPU to DP and Series 505 I/O by means

of the PROFIBUS-DP I/O channel.

You can only use one remote I/O annex card per 575 CPU.

The Series 505 remote I/O and PROFIBUS-DP annex cards use a dipswitch

for configuration when used with the 575–2104 CPU only. When used with

the 575–2105/–2106 CPUs, configuration is done with the dipswitch located

on the CPU. Refer to Section 4.10 for details on configuration.

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.

The installation of a remote I/O annex card has an effect on the power

consumption of the CPU. See Table B-2 to calculate power requirements for

Series 505 remote I/O and PROFIBUS-DP I/O annex cards.

If you have made allowances for the effects of annex card power

consumption on your system, you are ready to install your Series 505

remote I/O or PROFIBUS-DP annex card.
