Fieldbus Cabling

During cabling, channel 0 of the IO controller is connected to a port of the first IO device (slave device). The second port of the first
slave device is connected to the input port of the next slave device, etc. One port of the last slave device and channel 1 of the master
device remain unused.

Optional: You achieve greater failsafe network performance if you implement an additional redundant connection (MRP = Media
Redundancy Protocol) between the output port of the last slave device and channel 1 of the IO controller. IF2035 can participate in
an MRP ring as a client; however, it cannot manage the ring. To achieve ring functionality, all participants must be configured as ring
participants.
