MTConnect.NET-SHDR 4.4.0

SHDR Adapters

Adapter classes to handle the SHDR Agent Adapter Protocol associated with the MTConnect Standard.

Overview

The ShdrAdapter class handles the TCP connection to the Agent. SHDR conversion is handled in each individual class:

• ShdrDataItem : Handles converting Events and/or Samples with a Representation of VALUE to the appropriate SHDR format.
• ShdrCondition : Handles converting Conditions to the appropriate SHDR format
• ShdrTimeSeries : Handles converting Samples with a Representation of TIME_SERIES to the appropriate SHDR format
• ShdrDataSet : Handles converting Events and/or Samples with a Representation of DATA_SET to the appropriate SHDR format
• ShdrTable : Handles converting Events and/or Samples with a Representation of TABLE to the appropriate SHDR format

The ShdrAdapterClient class handles the TCP connection to read from the Adapter and add data to an IMTConnectAgent class.

Usage

There are several different ways to setup and add data to the ShdrAdapter

Initialization

using MTConnect.Adapters.Shdr;

string deviceName = "OKUMA.Lathe";
ShdrAdpater adapter = new ShdrAdapter(deviceName);
adapter.Start();

Add DataItems Individually

// DataItemId and CDATA
adapter.AddDataItem(new ShdrDataItem("L2estop", "ARMED"));

// DataItemId, CDATA, and Timestamp
adapter.AddDataItem(new ShdrDataItem("L2estop", "ARMED", DateTime.UtcNow));

If no timestamp is given then the timestamp will be set when the DataItem is sent to the Agent. To insure that all dataitems have the same timestamp, it can be set explicitly.

Add List of DataItems

var dataItems = new List<ShdrDataItem>();

dataItems.Add(new ShdrDataItem("L2p1execution", "READY"));
dataItems.Add(new ShdrDataItem("L2p1Fovr", 100));
dataItems.Add(new ShdrDataItem("L2p1partcount", 15));
dataItems.Add(new ShdrDataItem("L2p1Fact", 250));

adapter.AddDataItems(dataItems);

Store DataItems in Variables

ShdrDataItem executionDataItem = new ShdrDataItem("L2p1execution");
ShdrDataItem feedrateOverrideDataItem = new ShdrDataItem("L2p1Fovr");
ShdrDataItem partCountDataItem = new ShdrDataItem("L2p1partcount");
ShdrDataItem feedrateActualDataItem = new ShdrDataItem("L2p1Fact");

executionDataItem.Value = "READY";
feedrateOverrideDataItem.Value = 100;
partCountDataItem.Value = 15;
feedrateActualDataItem.Value = 250;

adapter.AddDataItem(executionDataItem);
adapter.AddDataItem(feedrateOverrideDataItem);
adapter.AddDataItem(partCountDataItem);
adapter.AddDataItem(feedrateActualDataItem);

Use Models

The DeviceModel class can be used to add data to an ShdrAdapter by setting the properties of the DeviceModel and adding those Observations to the Adapter as shown below:

using MTConnect.Models;
using MTConnect.Observations.Events.Values;

DeviceModel deviceModel = new DeviceModel("OKUMA.Lathe");
deviceModel.Controller.EmergencyStop = EmergencyStop.ARMED;

adapter.AddDataItems(deviceModel.GetObservations());

Conditions

ShdrCondition condition = new ShdrCondition("L2p1system", ConditionLevel.FAULT);
condition.NativeCode = "404";
condition.NativeSeverity = "100";
condition.Qualifier = "LOW";
condition.Message = "Testing from new adapter";

adapter.AddCondition(condition);

TimeSeries

List<double> samples = new List<double>();
samples.Add(12);
samples.Add(15);
samples.Add(14);
samples.Add(18);
samples.Add(25);
samples.Add(30);

ShdrTimeSeries timeSeries = new ShdrTimeSeries("L2p1Sensor", samples, 100);

adapter.AddTimeSeries(timeSeries);

DataSets

List<DataSetEntry> dataSetEntries = new List<DataSetEntry>();
dataSetEntries.Add(new DataSetEntry("V1", 5));
dataSetEntries.Add(new DataSetEntry("V2", 205));

ShdrDataSet dataSet = new ShdrDataSet("L2p1Variables", dataSetEntries);

adapter.AddDataSet(dataSet);

Tables

List<TableEntry> tableEntries = new List<TableEntry>();

// Tool 1
List<TableCell> t1Cells = new List<TableCell>();
t1Cells.Add(new TableCell("LENGTH", 7.123));
t1Cells.Add(new TableCell("DIAMETER", 0.494));
t1Cells.Add(new TableCell("TOOL_LIFE", 0.35));
tableEntries.Add(new TableEntry("T1", t1Cells));

// Tool 2
List<TableCell> t2Cells = new List<TableCell>();
t2Cells.Add(new TableCell("LENGTH", 10.456));
t2Cells.Add(new TableCell("DIAMETER", 0.125));
t2Cells.Add(new TableCell("TOOL_LIFE", 1));
tableEntries.Add(new TableEntry("T2", t2Cells));

// Tool 3
List<TableCell> t3Cells = new List<TableCell>();
t3Cells.Add(new TableCell("LENGTH", 6.251));
t3Cells.Add(new TableCell("DIAMETER", 1.249));
t3Cells.Add(new TableCell("TOOL_LIFE", 0.93));
tableEntries.Add(new TableEntry("T3", t3Cells));

ShdrTable table = new ShdrTable("L2p1ToolTable", tableEntries);

adapter.AddTable(table);

SHDR Conversion

Conversion to and from an SHDR message is done through methods in the ShdrDataItem, ShdrCondition, ShdrTimeSeries, ShdrDataSet, and ShdrTable classes. Each class overrides the base "ToString()" method and also contains a "FromString()" method. The "ToString()" method creates an SHDR compatible string from the object and the "FromString()" creates an object from an SHDR string.

ShdrDataItem.ToString()

ShdrDataItem availableDataItem = new ShdrDataItem("L2avail", Availability.AVAILABLE, DateTime.UtcNow);
Console.WriteLine(availableDataItem);

ShdrCondition.ToString()

ShdrCondition condition = new ShdrCondition("L2p1system", ConditionLevel.FAULT, DateTime.UtcNow);
condition.NativeCode = "404";
condition.NativeSeverity = "100";
condition.Qualifier = "LOW";
condition.Message = "Testing from new adapter";
Console.WriteLine(condition);

2022-02-01T13:55:11.8460000Z|L2p1system|FAULT|404|100|LOW|Testing from new adapter

ShdrTimeSeries.ToString()

List<double> samples = new List<double>();
samples.Add(12);
samples.Add(15);
samples.Add(14);
samples.Add(18);
samples.Add(25);
samples.Add(30);

ShdrTimeSeries timeSeries = new ShdrTimeSeries("L2p1Sensor", samples, 100, DateTime.UtcNow);
Console.WriteLine(timeSeries);

List<DataSetEntry> dataSetEntries = new List<DataSetEntry>();
dataSetEntries.Add(new DataSetEntry("V1", 5));
dataSetEntries.Add(new DataSetEntry("V2", 205));

ShdrDataSet dataSet = new ShdrDataSet("L2p1Variables", dataSetEntries, DateTime.UtcNow);
Console.WriteLine(dataSet);

ShdrTable.ToString()

List<TableEntry> tableEntries = new List<TableEntry>();

// Tool 1
List<TableCell> t1Cells = new List<TableCell>();
t1Cells.Add(new TableCell("LENGTH", 7.123));
t1Cells.Add(new TableCell("DIAMETER", 0.494));
