Configuration in STEP 7
Configuration in STEP 7
You configure the CP alternatively with the following configuration tools:
● STEP 7 V5
For configuring the security functions, you also require the Security Configuration Tool
(SCT).
● STEP 7 Professional
You will find the required versions in the section Project engineering (Page 30).
The following information on configuration applies to both configuration tools.
Interface configuration
6.6.1
The configuration of the network settings "Transmission medium / Duplex" is made in the
Properties dialog in the "Options" tab for both ports.
Automatic setting or individual network settings
As default, the CP is configured for automatic detection (autosensing).
Note
In normal situations, the basic setting ensures trouble
free communication. You should only
change this in exceptional situations.
If you create a manual configuration for the CP and disable the autonegotiation option, the
automatic negotiation of the network settings (autonegotiation) is no longer effective.
If, on the other hand, the communications partner works with autonegotiation, it is not certain
that communication will be established.
Only use manual configuration when the communication partner works with the same
manually set configuration.
