Hello,

the best way to obtain values from ethernet P8541 sensor using VB.NET is to write Web Service which should capture SOAP messages sent from sensor.

Use program TSensor (Transimtters setup utility) to setup where and how often should sensor sends SOAP messages.

Furhter is C# code example of Web Service for obtaining SOAP messages from P85xx sensors, which stores obtained values into D:\temp\soap.log. I hope it won't be a big problem to convert C#.NET to VB.NET.

Best regards

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Xml.Linq;
using System.IO;
using System.Text;
using System.Web.Services.Description;

namespace TransmittersWebService
{
    /// <summary>
    /// Example of web service for obtaining values from P85xx transmitters
    /// </summary>

    [SoapDocumentService(RoutingStyle = SoapServiceRoutingStyle.RequestElement)]

    [WebService(Namespace = "http://cometsystem.cz/schemas/soapP85xx_v2.xsd")]

    public class TransmittersSoap : System.Web.Services.WebService
    {

        [WebMethod(Description = "Example of processing sample from P85xx sensor.")]
        public bool InsertP85xxSample(string passKey, string device, string temp1, string temp2, string temp3, string temp4, string alarms, string tempU, string timer)
        {
            string data =   "Time: " +  DateTime.Now.ToString()
                          + ", serial number: " + passKey
                          + ", Temp(1): " + temp1
                          + ", Unit: " + tempU
                          + ", alarms: " + alarms;

            FileStream fs = new FileStream("d:\\temp\\soap.log", FileMode.Append);
            StreamWriter w = new StreamWriter(fs, Encoding.ASCII);
            w.WriteLine(data);
            w.Flush();
            w.Close();
            fs.Close();

            return true;
        }

    }
}
