The Flex devices in the ibaFOB-D network are identified via IP addresses. The ibaFOB-D network adapter has the following IP address by default: 172.29.0.100 and the subnet mask 255.255.0.0.

If this IP address is already in use in an existing network, it can be changed if the following rules are observed:

• The new IP address must also be a class B address.

• The subnet mask must not be changed.

• The last two digits 0.100 must not be changed.

In 32Mbit Flex mode, each device in the Flex ring is automatically assigned a fixed IP address that cannot be changed. The IP addresses of the connected Flex devices are made up of 4 digits (W.V.X.Y) and are assigned according to the following rules:

• W.V correspond to the first two digits of the IP address of the ibaFOB-D network adapter (172.29 by default)

• X corresponds to the card number (display of the ibaFOB-D board in the computer) *10 + link number, the device is connected to

• Y is the device address set with address rotary switch + 100

Examples

The IP address of the Flex devices is shown in the I/O Manager in the General tab and cannot be changed.

Changing the IP address of the ibaFOB-D network adapter

If the first two digits of the IP address of the ibaFOB-D network adapter are changed in an existing configuration, the ibaPDA configuration of all connected Flex devices must be applied again (click on <OK> or <Apply>) so that the first two digits of the IP address of the device are adjusted. Otherwise communication will be interrupted.
