Weed ControlNet fibre-optic repeaters

The Weed ControlNet EOTec 2C31 single self-healing ring (SHR) and 2C32 dual self-healing ring (DSHR) repeaters provide multiple communication paths between the various elements of the control system using ‘downstream multicasting’ technology.

In the event of a failure on one communication path, communications are still maintained along a secondary path or, in the case of a dual ring, tertiary paths.

Downstream multicasting transmits an incoming message in multiple directions and ensures that while directing the message towards all nodes in the ring, it is never retransmitted back to the point of origin. Process downtime due to an accidental break of one of the fibre cables is therefore eliminated.

Local and remote diagnostic tools are incorporated into the repeaters to enhance reliability and support preventive maintenance. These address power input quality, optical fibre fault, location of optical fibre break and link status. Data on the optical fibre lines is constantly monitored. If a fibre fails to transfer light or is broken, an alarm is instantly activated.
