Distributed Network Protocol Interface Slave Module

PTQ-DNPS

The ProTalkQ DNPS 3.0 Slave Communication Module (PTQ-DNPS) is a Quantum backplane compatible module that allows Quantum processors to easily interface with DNP 3.0 compatible devices and hosts. Devices commonly supporting the protocol include relays, breakers, sub-station communication modules and other serial devices most commonly associated with power monitoring.

The module supports DNP Subset Level 2 features and some of the Level 3 features allowing the many SCADA and field devices supporting the DNP protocol to be integrated into the Quantum platform. The module acts as a gateway between the DNP network and the Modicon backplane. The data transfer from the Quantum processor is asynchronous from the actions on the DNP network. Databases are user defined and stored in the module to hold the data required by the protocol.

The PTQ-DNPS module is a powerful communication interface for Quantum platform processors. Developed under license from Schneider Electric, the module incorporates proprietary backplane technology that enables powerful data access to the Quantum processor.

The PTQ-DNPS module is the ideal solution for many applications where DNP 3.0 Slave protocol connectivity needs to be added to a Quantum system.
The DNPS solution has been 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.

DNP 3.0 Slave Protocol Specifications

The DNP Slave port(s) accepts DNP commands to control and monitor data stored in the module?s DNP Slave databases.

• Report-by-Exception data is logged to the module?s database
• Supports unsolicited messaging
• Each DNP point type is user configurable by point
• Total point counts must be configured so that Class 0 responses do not exceed 2048 bytes in size
• Class assignments are completely user-definable on a Type and point basis (BI, AI, FI, DI point types)
• The analog inputs are class and deadband configurable on a point basis for all formats (integer, float, double float)
• Supports clock synchronization from a master or from the Quantum
• 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
• In addition to the module generated events, AI and BI events can be generated in the Quantum and transferred to the module (useful with external timestamping hardware)
• Configurable event buffer transmission threshold based on count and/or time since last event transmission
• Collision avoidance algorithm per DNP organization for redundant port switching (redundant slave mode)
• Special modem AT command string and timing support for dialing out on redundant port (redundant slave mode)

This module is designed by ProLinx Communication Gateways and incorporates licensed technology from Modicon (Quantum backplane technology).
