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

If this IP address is already used in a network, it may be changed in accordance with the following rules:

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

  • The subnet mask must not be changed

  • The last two octets 0.100 must not be changed.

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

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

  • X is assigned automatically, starting from 100

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

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

When the IP address of the ibaFOB-D network adapter has been changed (only the first two octets are allowed), all connected Flex devices must apply the ibaPDA configuration again (clicking on <OK> or <Apply>) in order to amend the first two octets of the new IP address. Otherwise the connection will be interrupted.
