Thus, in , GE-Harris Canada formerly known as Westronic used the partially completed IEC protocol specifications as the basis for an open and immediately implementable protocol that specifically catered to North American requirements. The protocol is designed to allow reliable communications in the adverse environments that electric utility automation systems are subjected to, being specifically designed to overcome distortion induced by electromagnetic interference EMI , aging components their expected lifetimes may stretch into decades , and poor transmission media. Security[ edit ] Because smart grid applications generally assume access by third parties to the same physical networks and underlying IP infrastructure of the grid, much work has been done to add Secure Authentication features to the DNP3 protocol. Some vendors support encryption via bump-in-the-wire for serial communications or virtual private networks for Internet Protocol-based communications.

DNP 3. System integrators worldwide have benefitted from the value of the powerful line of interoperability gateways offered by FieldServer. Now, QuickServer adds to that value by running the same robust FieldServer protocol conversion software on a highly cost-effective platform backed by the experience, engineering expertise and proven technical support that integrators have come to expect from FieldServer.
There is a basic QuickServer that can handle up to points and an enhanced QuickServer that can handle points. Each QuickServer can handle up to points. Each QuickServer includes browser-based tools to make it easy to set-up QuickServer and perform diagnostics including determination of status, network settings, node information, map descriptors and more.
Quickserver Gateway Serial-Ethernet The QuickServer is a high performance, fully configurable, cost effective Building and Industrial Automation gateway for integrators to easily interface devices to networks in commercial buildings and industrial plants.

The FS-QS can support up to points. The FS-QS can support up to 3, points. The FS-QS can support up to 5, points.
Every QuickServer includes browser-based tools to make it easy to set-up QuickServer and perform diagnostics including determination of status, network settings, node information, map descriptors and more. The Modbus TCP driver uses port This port is not configurable. The specification can be found at www. The FieldServer can emulate both a Client and a Server simultaneously on the same ethernet port. The information that follows describes how to expand upon the factory defaults provided in the configuration files included with the FieldServer.
There are various register mapping models being followed by various vendors. A maximum of registers can be mapped of each type. Use this format where addresses of each type are defined in the range Note 1: If vendor document shows addresses in extended Modicon i. The FieldServer can emulate either a Server or Client. When the FieldServer is a Server slave , only one Client master can communicate to it. As ambitious an undertaking as this was, we reached this objective. DNP3 has been designed to be as close to compliant as possible to the standards as they existed at time of development with the addition of functionality not identified in Europe but needed for current and future North American applications e.
DNP3 is an open and public protocol. In order to ensure interoperability, longevity and upgradeability of, protocol the DNP3 Users Group has taken ownership of the protocol and assumes responsibility for its evolution. The DNP3 Users Group Technical Committee evaluates suggested modifications or additions to the protocol and then amends the protocol description as directed by the Users Group members. Among its robust and flexible features DNP3 includes: Output options Addressing for over 65, devices on a single link Time synchronization and time-stamped events Broadcast messages Data link and application layer confirmation DNP3 was originally designed based on three layers of the OSI seven-layer model: application layer, data link layer and physical layer.
The application layer is object-based with objects provided for most generic data formats. The data link layer provides for several methods of retrieving data such as polling for classes and object variations. The physical layer defines most commonly a simple RS or RS interface. DNP3 is very efficient for a layered protocol while ensuring high data integrity.
This includes RTU to IED communications, master to remote communications, and even peer-to-peer instances and network applications.
It permits multiple masters and encourages distributed intelligence. Users can expect many benefits from using DNP3. In the short term: Interoperability between multi-vendor devices Fewer protocols to support in the field Reduced software costs.
