Valve Device Router
Brand: Rotork PLC
The VDR (Valve Device Router) collects reported data from up to 32 associated VDs and wirelessly transfers the information to the next VDR.
The TVDR (Tunneling VDR) is the last-hop that passes on all the collected data from the string of VDRs to the site network for processing and analysis.
The VDR network acts as a relay that transmits messages, received from remote VDRs, through a ZigBee wireless network, until they reach a TVDR.
One or more TVDRs are connected to the RI Wireless Gateway using TCP/IP communication between all VDRs and the site network.
ZigBee mesh technology is implemented ensuring the required routing redundancy for very high communication reliability.
The TVDR generates a wireless heartbeat message over fixed periods, and broadcasts it between the VDRs for mapping routes and diagnosing communications performance.
