DNPQ3.0 Master/Slave

PTQ-DNPQ

Applications

The PTQ-DNPQ module is the ideal solution for many applications where DNP 3.0 Master/Slave protocol connectivity must be added to a Quantum or Unity system.

The DNP solution is designed to address the expanding interest in the DNP 3.0 protocol. The protocol was developed for the Power Utility industry and is recommended by the IEEE for RTU-IED communication applications. Additional industrial applications are quickly arising in the Water/Wastewater and Oil and Gas industries.

Functional Specifications

The module has two DNP protocol ports that can be configured to operate in a Master/Slave or Slave/Slave redundant port configuration. User defined internal register space is accessible to the protocol driver and to the Quantum processor memory.

Redundant Slave Port Operation

When configured in the Slave/Slave port configuration, the module's slave ports operate in a primary and secondary fashion. In this mode, a single host polls the module via redundant physical layer connections.

DNP 3.0 Slave Protocol Specifications

The DNP Slave port accepts DNP commands to control and monitor data stored in the module's DNP Slave databases. If a DNP Master port is configured, a portion of the slave databases can be derived from or can control IED devices connected to the DNP master port.

• Report-by-Exception data is logged to the module's database
• Supports unsolicited messaging
• Each DNP point type is user configurable by point
• Class assignments are completely user-definable on a Type and point basis (BI, AI, FI, DI point types)
• Supports clock synchronization from a master or from the processor
• Support for four octet-strings are supported (object type 110) in the slave driver to return version and other module information
• Up to 400 events are stored for Floats, Binary In, Analog In and Double Inputs
• Configurable event buffer transmission threshold based on count and/or time since last event transmission
• Collision avoidance for redundant port switching
• Special modem AT command string and timing support for dialing out on redundant port.

DNP 3.0 Master Protocol Specifications

• The DNP 3.0 Master port can be configured as a virtual DNP Master device that actively issues user-defined DNP commands to nodes on the network.
• Supports 300 user defined commands
• Master port logically supports up to 40 slave devices
• Individual command configuration includes conditional or continuous polling, Poll Delay Time
• Slave status and Command status available for transfer to the processor
• Event data received from the slave devices updates the module database (Date and Time stamping is not stored or used by module)
• Special command handling for Digital Output CROB under processor control for pulse output control
• Supports Report-by-Exception and Unsolicited Responses on a Time Interval basis or on a user determined Event Count basis. Analog and Binary input points are supported.

DNP 3.0 ports (PRT1 & PRT2)

• Memory usage is user definable
• Full radio, modem and multidrop support
• Support for the storage and transfer of all DNP data types across the backplane.
