For information on replacing previous modules, refer to the information in section
Diagnostics and upkeep (Page 95).
Note
Module replacement in PROFINET CBA
With PROFINET CBA, interconnection information is stored only on the CP. As a result the
benefits of "Module replacement without PG" function (storage of configuration data on the
CPU) cannot be made full use of after loading PROFINET CBA interconnections.
You have the two following options:
• Using the CPLUG in the new module
You insert the previously used CPLUG in the replacement module; interconnection
information is then available again.
• Using a new module with a new CPLUG
After replacing a module, you need to download the interconnection information to the
new CP using SIMATIC iMap.
Module replacement: Special feature of IP address assignment from a DHCP server
When configuring in the Properties dialog, you can specify the IP configuration of the CP.
One option here is that the CP obtains the IP address from a DHCP server.
Note
Recommendation: Configuring a client ID
When replacing modules, remember that the factoryset MAC address of the new module is
different from the previous module. When the factoryset MAC address of the new module is
sent to the DHCP server, this will return either a different or no IP address.
If, after replacing a module, you want to make sure that the CP always receives the same IP
address from the DHCP server, follow the steps below when creating the IP configuration:
•
Always configure a client ID for the CP in the DHCP configuration and configure your
DHCP server accordingly.
If, in exceptional situations, you have configured a new MAC address instead of the MAC
address set in the factory, the configured MAC address will always be transferred to the
DHCP server. In this case, the new CP also has the same IP address as the previous CP.
