5.5 Replacing a module
IE/PB LINK PN IO
74 Operating Instructions, 11/2017, C79000-G8976-C393-02
When replacing a predecessor module (6GK1 411-5AB00) with the LINK (6GK1 411-5AB10)
. The following variants can be distinguished:
●
Replacement with unchanged configuration (module replacement)
An existing module is replaced by a new module without changing the configuration.
To load the unchanged configuration on the new module, two methods are possible:
– Load the existing configuration data on the new module.
– Insert the C-PLUG of the predecessor module in the new module.
Note
Older C-PLUG cannot be overridden with data of the new LINK
A C
-
PLUG of the predecessor module cannot be overridden with data of the new LINK.
If you want to load the configuration data of the link 6GK1
411-5AB00 on the C-PLUG of
the predecessor module, you must first reformat the C
-PLUG. See section C-PLUG
38) for information on this.
●
Replacement with new configuration
An existing module is replaced by a new module with a new configuration.
If adaptations are made to the configuration, the IE/PB LINK PN IO can be used instead
of a module with firmware version V2.x or V1.0. The LINK used previously is replaced by
the new LINK in the configuration:
Load the new configuration on the new module.
Unless otherwise specified, in both cases, the range of functions of the previous module
continues to be supported.
Replacing a module without PG/PC
An existing module can be replaced by a new module without changing the configuration.
To load the unchanged configuration on the new module, insert the C-PLUG of the removed
module in the new module.
For information on replacing with previous modules, refer to the information in section
Replacing older modules (Page 73).
Obtain IP address from a DHCP server
When configuring in STEP 7, you can specify the IP configuration for the LINK. One option
here is that the LINK obtains the IP address from a DHCP server.
The DHCP server can assign the IP address based on the client ID, the MAC address or the
host name.
If after a replacement, the LINK should always receive the same IP address from the DHCP
server, always configure a client ID or a host name.
