Extremely fast re-configuration

Did you know that the ring re-configuration time of the ODW series is extremely fast?

At the birth of industrial data communications, serial protocols were very limited in how many devices and the network complexity they could support. These limitations allowed for very small delays in the communication as they were designed for few devices and simple network configurations.

However, with a growing need for data communications with capacity for greater distances and above all, ring redundancy, new technology had to be able to co-exist with the old technology. Because of the narrow delays of the old serial protocols it is essential that the ring re-configuration timing is really fast or the communication will run into problems.

The Westermo ODW-series of serial to fibre converters are capable to delivering solutions with an extremly fast fail-over time even in very large ring topologies. A theoretical calculation with 100 ODW devices in a ring network with a total distance of 40 km would only take 2.8 ms to recover. This is so fast that the protocols would not even be aware of the network recovery, which means that any standstill because of network downtime could be avoided.
