retVal = myNetwork.ScanNetworkDevices(out devices);
if (!retVal.Succeeded)
return;
foreach (IProfinetDevice dev in devices)
{
ICPU devAsCpu = dev as ICPU;
if ((devAsCpu != null) && (devAsCpu.IP == targetIPAddress))
{
DateTime curTime = new DateTime();
retVal = devAsCpu.GetCurrentDateTime(new EncryptedString(""),
out curTime);
}
