Siemens S7 Controller (STEP7) operation properties for disaster recovery

Specify default disaster recovery schedule settings for Siemens S7 Controllers (STEP7) in

Tools

>

Options

.

Specify the settings of a particular Siemens S7 Controller (STEP7) asset in an existing schedule on the

Schedules

tab. Changes to the settings within a schedule override the default settings for that instance.

(Only available when editing an existing schedule, not when setting defaults.) Specify the version of the backup data binder to compare to the controller files.

(Only available when editing an existing schedule, not when setting defaults.) For Siemens S7 Controller (STEP7) devices, the configuration data is not compared during a backup and compare operation unless specified. Set the software to compare to configuration data and specify the version of the configuration data binder to compare to the device files.

Set to

Always

to create a backup version even if it is exactly the same as the last compared backup version. This is the default setting.

Set to

On Differences Found

to create a backup version only if differences are found. If the existing backup is the same as the information in the controller aside from excluded data blocks, then no backup is saved.

When you set up the binder for the Siemens S7 Controller (STEP7), you had the opportunity to exclude files that you did not want included in the binder. Here you can exclude blocks of the Siemens S7 Controller (STEP7) program that you do not want included in a backup or a backup and compare operation.

Click in the

Block Options

field and then click . Fill in the

Block Options

dialog box.

Set to

True

to compare the length and structure (data type) of the data blocks. This comparison ensures that important changes to the length and structure of blocks, such as changing the structure of a value, or deleting a value, are detected even if the data block is excluded from the compare. It also detects if a whole data block is added or removed. This setting detects content changes, changes to the length and structure.

Set to

False

to compare only the content (values) of the data blocks, but not the length and structure.

Unexpected comparison results

: If you manually change an initial value for a parameter in a data block using your editing software for the Siemens S7 Controller (STEP7), it will register as a change in length and structure. Even if you use

Block Options

to exclude the data block, a change in length and structure is detected during a comparison if

Compare Data Blocks by Length and Structure

is set to

True

.

Also, if you manually change an initial value for a parameter in a data block, the connection between the address and the symbolic name is lost. Only the address can be shown and a backup and compare operation will report differences. The symbolic names are still available in the project in the Configuration Data binder.

The email addresses separated by semicolons (;) to which notification will be sent if the compare finds differences between the specified backup data or configuration data version and the data on the physical device.

The email addresses separated by semicolons (;) to which notification will be sent when the operation completes for the asset. If a backup and compare schedule completes without differences, an email is sent to this list. If it completes with differences, an email is sent to the

Event Compare Differences Detected

list, not this list.

The email addresses separated by semicolons (;) to which notification will be sent when the operation fails.

This defaults to

True

to attach a report of differences to the email if the backup and compare schedule finds differences between the specified backup data or configuration data version and the data on the physical device. Select

False

to send an email without an attached report.
