DNP 3.0 over Ethernet Communications Module
MVI71-DNPSNET
The MVI71 DNP 3.0 Server Ethernet Communications Module supports the implementation of the DNP 3.0 (Distributed Network Protocol) over Ethernet, allowing PLC processors to easily communicate with host systems supporting the protocol. The module supports DNP Subset Level 2 features and some Level 3 features.
Features and Benefits
The MVI71-DNPSNET (Distributed Network Protocol Module over Ethernet) allows Rockwell Automation PLC processors to easily communicate with other DNP protocol-compatible devices.
The module supports DNP subset level 2 features and some Level 3 features. The MVI71-DNPSNET module acts as an input/output module between the DNP Ethernet network and the Rockwell Automation backplane. The data transfer from the PLC processor is asynchronous from the actions on the DNP network. Databases are defined in the module to house the data required by the protocol.
General Specifications
- Single Slot - 1771 backplane compatible
- The module is recognized as an Input/Output module and has access to processor memory for data transfer between processor and module
- Ladder Logic is used for data transfer between module and processor. Sample ladder file included.
- Configuration data obtained from configuration text file downloaded to module. Sample configuration file included.
Applications
With the growing usage of the DNP protocol over Ethernet technology in the industrial marketplace, this product has a wide variety of application uses. Industries that use this technology include:
- Power and distribution applications
- Petrochemical
- Water and Gas Applications
- SCADA and DCS applications
Functional Specifications
The MVI71-DNPSNET module accepts DNP commands to control and monitor the data stored in the DNP databases. This data is passed between the module and the PLC processor over the backplane for use in user applications.
- DNP databases to house data for the slave port supporting the following maximum input counts
- Binary input: 8000 points (500 words)
- Binary output: 8000 points (500 words)
- Counter: 250 (500 words)
- Analog input: 500
- Analog output: 500
- Module memory usage that is completely definable
- Data movement between module using block-transfer or side-connect interface
- Ethernet port supporting both TCP and UDP over Ethernet
- Supports DNP 3.0 in a level 2 implementation
- Supports sending of input event data from the ladder to the module
- Supports time synchronization from/to processor
- Network configurable via text fileStatus and error information
