Description
password
EncryptedString
In This method opens a legitimized connec-
tion to the device. Therefore, a password
may be required.
aDiagnosticsItems
List<DiagnosticsItem>
Out A collection of Diagnostics Items: Each
item in the collection represents an entry
in the diagnostics butter.
This method reads the current diagnostics entries from the CPU. Each entry is represented
as a
DiagnosticsItem.
The following example searches the
IProfinetDeviceCollection for a CPU at a specific IP
address. When found, the diagnostics information is read from the CPU.
uint targetIPAddress = 0xC0A80001; // 192.168.0.1
List<DiagnosticsItem> aLogs = new List<DiagnosticsItem>();
IProfinetDeviceCollection devices = new IProfinetDeviceCollection();
Result retVal = myNetwork.ScanNetworkDevices(out devices);
if (retVal.Succeeded)
{
foreach (IProfinetDevice dev in devices)
{
ICPU devAsCpu = dev as ICPU;
if ((devAsCpu != null) && (devAsCpu.IP == targetIPAddress))
{
retVal = devAsCpu.GetDiagnosticsBuffer(new EncryptedString(""),
out aLogs);
if (retVal.Succeeded)
{
for (int idxLog = 0; idxLog < aLogs.Count; idxLog++)
{
string descr = aLogs[idxLog].Description1;
}
}
}
}
