New value for the CPU current time.
This method sets the current time for the CPU. The configured time transformation rules are
not affected by this action. Therefore, the specified DateTime value is based on UTC time,
not the local time.
The following example traverses the entire industrial network and sets the current time for
each CPU device to the current time of the PG/PC.
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)
{
retVal = devAsCpu.SetCurrentDateTime(new EncryptedString(""),
DateTime.UtcNow);
}
}
}
