32Mbit P2P mode

You should use 32Mbit P2P mode, if

 there is only a single fiber optic cable available or

 you want to connect two ibaLink-io-embedded modules or

 you want to connect an ibaLink-io-embedded module to ibaLogic.

In this mode, the module has to be configured as described in chapter 7 “Software” and

the user has to ensure that the complete signal configuration of the application is also

set up correctly in the 2nd device (ibaLink-io-embedded, ibaPDA or ibaLogic).

32Mbit mode

In 32Mbit mode, up to 16 ibaLink-io-embedded modules can be connected in a ring with

ibaLogic. ibaLogic can read and write process data to all devices in the ring. The devices

can read all data which is currently on the fiber optic link, but can only write data on their

parts of the fiber optic link.

The application has to ensure, that only the allowed signals at the correct location in the

fiber optic buffer are used. The configuration of the ibaLink-io-embedded module will

check this. If the configuration is wrong, it will not be applied and the red LED is blinking.

The rotary switch of the ibaLink-io-embedded is used to select the device number (0 to

F). It is not allowed to have two devices in the ring with the same number.
