Advanced Connectivity


GRIDlink AutoDR® is truly plug and play out of the box

  1. Wire the DC digital outputs to the relays controlling the plant equipment.
  2. Connect the Ethernet port to the local LAN with connection to the Internet.
  3. Power the unit with 10-30 VDC.
  4. Enter the URL Web address supplied by the Utility.

GridLink ® will begin to immediately participate in your Utility’s Auto Demand Response Program.

Flexible Ethernet Connection

Plugging the GridLink ® into the plant Ethernet Network to connect to the Utility’s DRAS server is often the easiest solution. As in so many companies however, network security is very important and it may be difficult to add a device which connects to an external server without significant IT intervention.

With the addition of a cellular router, GridLink® can connect to the DRAS Server via the Internet and completely bypass the Local Area Network.

Modbus/DNP3 Communication

Since the GridLink ® is an advanced RTU, it can be configured as a Modbus Master or Modbus/DNP3 Slave and communicate through it’s Ethernet port or RS232/RS485 serial ports. This give the user unlimited flexibility to connect to plant Digital Control Systems, SCADA software (Wonderware, Citect, Intellution etc.) and Building Management Systems.

Cellular VPN

Using the cellular connection, a Virtual Private Network could be set up to one or more other cellular routers. This would give aggregators the ability to connect directly to the GridLink® from anywhere for monitoring and troubleshooting.

Cellular Network

PROBLEM: Say there is a need to connect a number of participants using GridLink® to a central control room all located over a wide area. The status of each register must be in real time polled every few seconds.

SOLUTION: Provide a GridLink® cellular router at each participant’s location with a VPN connection to one GridLink® cellular router with embedded Modbus located at the central control room. This router will poll all the GridLinks at predetermine intervals and store the results in registers in the router. The central control system would be able to read and write to the Modbus registers located in the Modbus cell router which in turn read and write to the individual GridLinks.
