Setting a Temporary IP Address
If supported by the host CPU
70
, use the Set Temporary IP Address utility to specify an IP address in place
of one that has been lost or forgotten.
The following restrictions apply when using the Set Temporary IP Address utility:
▪
To use the Set Temporary IP Address utility, the PLC CPU must not be in RUN Mode. IP address
assignment over the network will not be processed until the CPU is stopped and is not scanning
outputs.
▪
The Set Temporary IP Address utility does not function if communications with the networked
PACSystems target travel through a router. The Set Temporary IP Address utility can be used if
communications with the networked PACSystems target travel across network switches and hubs.
▪
The current user logged on the computer running the Set Temporary IP Address utility must have full
administrator privileges.
▪
The target PACSystems must be located on the same local sub-network as the computer running
the Set Temporary IP Address utility. The sub-network is specified by the computer's subnet mask
and the IP addresses of the computer and the PACSystems Ethernet Interface.
Note:
To set the IP address, you will need the MAC address
of the Ethernet Interface to which PME will be
connected.
1.
Connect the PACSystems CPU LAN to the Ethernet
network on which PME is communicating.
2.
In the Project tab of the Navigator, right click the
PACSystems target, choose Offline Commands, and then
choose Set Temporary IP Address. The Set Temporary IP
Address dialog box (Figure 39) appears.
3.
In the Set Temporary IP Address dialog box, do the
following:
▪
Key in the 12-digit hexadecimal MAC address (two
digits per field).
▪
In the
IP Address to Set
box, specify the temporary IP
address you want to set for the PACSystems LAN.
▪
If necessary, select the Enable Network Interface
Selections check box and specify the IP address of
the network interface on which the PACSystems is
located.
4.
When the fields are properly configured, click the Set IP
button.
5.
The IP Address of the specified PACSystems LAN will be
set to the specified temporary address. This may take up
to a minute.
After the programmer connects over Ethernet, the permanent IP address for the Ethernet interface,
which is set in the hardware configuration, will have been downloaded to the CPU.
The temporary IP address remains in effect until the Ethernet interface is restarted, power-cycled or until
the hardware configuration is downloaded or cleared.

Not supported by RX3i CPE400 and RSTi-EP CPE100/CPE115.
