Detailed Descriptions of the Fieldbus Network Adapters

Changing the mode of IP mapping via the network adapter
Providing that the adapter has already received an address, the mode of IP assignment ca
be changed via the following data object: TCP/IP object 0xF5 (245), instance 0x01 (1),
attribute 0x03 (3). The options are Static [0], BootP [1] or DHCP [2].
When switching to mode Static, the adapter will keep the address that has been assigned
automatically before; this address will be saved permanently. When switching to an
automatic mode the adapter will start a request on the respective server immediately.
Allocating a new IP address
A new IP address can be allocated via the following data object: TCP/IP object 0xF5 (245),
instance 0x01 (1), attribute 0x05 (5). The new address will be saved permanently, if the
mode Static is set. Using the automatic assignment, the address will be used temporarily
only.
Address Conflict Detection
After an address has been allocated to the adapter, it will be checked whether this address
is already used within the network (ACD, Address Conflict Detection). In case an address
conflict is detected, and the address is rejected, the adapter requests another address from
the DHCP server, as long as DHCP mode is active. When using mode BootP or Static, the
adapter must be disconnected from the Ethernet and connected again.
The address check is executed every two minutes during operating. It can be turned off via
the following data object: TCP/IP object 0xF5 (245), instance 0x01 (1), attribute 0x0A (10).

HTTPS setting
Note:
It is strongly recommended to use HTTPS protocol for connecting to the Network
adapter webserver by setting the ‘’
only HTTPS; n
o HTTP’’ in ‘’HTTPS setting’’
parameter.
To change the HTTPS setting in EPXEIP001, follow the below steps-
1.
Power up the Network adapter and connect the adapter to PC via micro USB
connection.
2.
Open internet browser and enter the IP address of the network adapter (default:
192.168.5.202). Web page of Network adapter opens.
3.
Click Login and enter User Name and Password and login to the Network Adapter
4.
Click on Component List and select Network Adapter
