Minimal CIP, Ethernet/IP library in java used by ProtocolWhisperer. GetAttribute and SetAttribute for PowerFlex VFDs and other CIP devices supported.

Overview

This library allows GetAttribute and SetAttribute requests to network capable CIP devices such as PowerFlex drives. The library is implemented in ProtocolWhisperer to allow logging of parameters.

Supported objects

Presently the only supported object is class 0x93 DPI Parameter object. Supported attributes are 7 - DPIOnlineReadFull and 9 - Parameter Value.

Example

Reading the first 400 drive parameters

CIPClient client = new CIPClient("192.168.1.10");
try
{
    client.connect();
    for (int i = 1; i < 400; i++)
    {
        DPIOnlineReadFullResponse response = (DPIOnlineReadFullResponse)client.getAttribute(0x93, i, 0x07);
        String readWrite = "RO";
        if (!response.getReadOnly())
        {
            readWrite = "RW";
        }
        System.out.println(readWrite + " " + response.getParamName() + ": " + response.getParamValue() + response.getUnits());
    }
}
catch(Exception e)
{
    e.printStackTrace();
}

Writing parameters

CIPClient client = new CIPClient("192.168.1.10");
try
{
    client.connect();
    DPIOnlineReadFullResponse response = (DPIOnlineReadFullResponse)client.getAttribute(0x93, 52, 0x07);
    //get the data formatter to correctly format the bytes
    CIPDataFormatter formatter = response.getCIPDataFormatter();
    //set the average kWh Cost to $0.13/hr
    CIPResponse setResponse = client.setAttribute(0x93, 52, 0x09, formatter.displayValueToBytes(0.13));
}
catch(Exception e)
{
    e.printStackTrace();
}
