Installing 505 System Hardware SIMATIC 545/555/575 System Manual

3.7 Installing the PROFIBUS-DP Annex Card (Optional)

To install the PROFIBUS-DP annex card, PPX:505–CP5434–DP, on a

545–1103 or 545–1105 CPU, follow the procedure described below and

consult Figure 3-6.

1. Carefully set your CPU board on a static-dissipative surface.

CAUTION

Electronic equipment is sensitive to, and can be damaged by, electrostatic

discharge.

Ensure that personnel make contact with a static-dissipative pad and/or wear a

grounded wrist strap when handling the CPU cards or modules.

2. Remove the PROFIBUS-DP port cover from the bezel. The port cover is

not reusable.

The port cover is secured by plastic pins that project through the bezel

and are secured on the back side by clamps. First clip the pins off as

close to the clamps as practicable; then pry the clamps loose and

remove the port cover.

3. To attach the annex card to the CPU board, insert the 9-pin

D-connector of the annex card into the CPU bezel opening and align the

annex connector with the connector on the CPU. Apply pressure until

the connectors are mated.

4. Insert metal screws (supplied) into the screw-holes of the

PROFIBUS-DP communication port and tighten to a maximum of

5.2 in–lb (0.6 N–m) torque.

5. Insert plastic screws (supplied) through the CPU into the annex card

standoffs and tighten.
