password
EncryptedString
In This method opens a legitimized connec-
tion to the device. Therefore, a password
may be required
This method resets a CPU to its factory defaults.
The following example searches the
IProfinetDeviceCollection for a CPU at a specific IP
address, and calls the
ResetToFactory method.
uint targetIPAddress = 0xC0A80001; // 192.168.0.1
IProfinetDeviceCollection devices = new IProfinetDeviceCollection();
Result retVal = myNetwork.ScanNetworkDevices(out devices);
if (retVal.Succeeded)
{
IProfinetDevice dev = devices.FindDeviceByIP(targetIPAddress);
if (dev != null)
{
ICPU devAsCpu = dev as ICPU;
if (devAsCpu != null)
{
retVal = devAsCpu.ResetToFactory(new EncryptedString(""));
}
}
}
Note
The
ResetToFactory method is not allowed for an S7 fail-safe CPU. The SIMATIC
Automation Tool API will block this operation for a fail
-safe When the software determines
that this metho
d was called for a fail-safe CPU, a specific error
(ErrorCode.FailsafeAccessNotAllowed
) is returned.
