only when the power is off.
Turn off your PG/PC and pull the power cable connector before you start the hardware
installation.
Components can be damaged or destroyed by electrostatic discharge. When installing,
keep to the rules for electrostatically sensitive devices (ESD).
• Pick up components and modules only by their edges. Do not touch the pins or
conductors.
• Before opening the PG/PC, make sure that you discharge any electrostatic charge from
your body. You can do this by touching metal parts on the back panel of the PG/PC
pulling the power plug.
• Make sure that you also discharge any electrostatic charge from tools you intend to use
for the work on the PG/PC.
• Do not operate the PG/PC with the housing open.
The communications processor must sit firmly and uniformly in the slot. Check that the
module sits firmly in the slot as described in the manual accompanying your PG/PC.

PCI Express
Please note: The communications processors of the 5613 / 5614 series are PCI cards. The
CP 5623 and CP 5624 communications processors are PCI Express cards. This means that
you can only replace previous versions with a CP 5623 / CP 5624 if ther

To be able to configure the communications processor, the following engineering or
configuration tools are available:
● STEP 7 V5.5
● STEP 7 Professional (TIA Portal)
● Communication Settings (COML S7)
The steps involved are described in the "Commissioning PC Stations" manual or in the
relevant online helps.
Compatibility during configuration
If there is not a CP 5623 / CP 5624 available in the hardware catalog of your STEP 7
version, you can also select a previous version for configuration.
● For the CP 5623, select a configuration of:
– CP 5613 A2 or
– CP 5613
● For the CP 5624, select a configuration of:
– CP 5614 A2 or
– CP 5614
The CP 5623 / CP 5624 is downwards compatible with the configurations of the previous
versions.
Configurations not compatible
The DP slave configuration of a CP of the 56x3 series is not compatible with the DP slave
configuration of a CP from the 56x4 series. This means, for example, that the DP slave
configuration of a CP 5623 cannot be loaded on a CP 5624 - and vice versa - because the
slave will not work with this configuration.
