Reloaded IP access control list
Entries entered later in the IP access control list by HTTP / HTTPS are no
t saved on the CPU.
After a module has been replaced, previous entries that had been entered later must be
reloaded in the IP access control list.
For information on replacing previous modules, refer to the information in section
Diagnostics and upkeep (Page 81).
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.
ommendation: Configuring a client ID
When replacing modules, remember that the factory
set MAC address of the new module is
different from the previous module. When the factory
set 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 C
P 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.
7.3.4 Loading new firmware
Options for a firmware update
You can use the following alternative methods to download a new firmware file to the CP:
• The firmware loader supplied with STEP 7 V5
Requirement for downloading:
– To download firmware, you require an Industrial Ethernet CP module in the PG/PC (for
example, CP 1613) or a normal Ethernet module with the "Softnet" software package.
– The S7ONLINE interface must be set to the "ISO - Industrial Ethernet" protocol. It is not
possible to download using TCP/IP (and therefore not to other networks).
Always run the download using the active MAC address of the CP!
