5.1.1 Features and Benefits
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 PLC platform. The module acts as an
input/output module between the DNP network and the PLC backplane. The data
transfer from the PLC 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.
5.1.2 General Specifications
ƒ Single Slot – 1771 backplane compatible
ƒ The module is recognized as an Input/Output module and has access to
processor memory for data transfer between processor and module
ƒ Ladder Logic is used for data transfer between module and processor.
Sample ladder file included.
ƒ Configuration data obtained from configuration text file downloaded to
module. Sample configuration file included.
