Description
Password
EncryptedString
In This method opens a legitimized connec-
tion to the device. Therefore, a password
may be required.
strFile
string
In A fully-qualified path and filename where
the backup should be stored.
This method is used to back up the data in a CPU. Not all CPUs support the back up/restore
feature. The property
BackupAllowed can be checked to ensure that the current CPU supports
this feature
The following example searches the
IProfinetDeviceCollection for a CPU at a specific IP
address. When found it checks that the CPU supports the back up feature, and calls the
Backup method.
uint targetIPAddress = 0xC0A80001; // 192.168.0.1
string bkFile = @"C:\MyCPUBackupFile.s7pbkp";
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) &&
(devAsCpu.BackupAllowed == FeatureSupport.BackupAllowed)
)
{
retVal = devAsCpu.Backup(new EncryptedString(""), bkFile);
}
}
}
