Reset CPUs and modules to factory default values
Reset selected devices to factory default values
You can reset selected devices to factory default values, except for the IP address. The IP
address that exists before the operation is retained, so your network IP assignments are
preserved.
Note
For safety reasons, the Reset to factory defaults operation is not allowed on fail
-safe
devices.
By default, the reset factory defaults operation allows only a single processing thread that
must complete execution, before the next device operation is executed. To change this
behavior, see the Tool menu (Page 62) topic. Be aware of the risk of doing multi-thread
firmware updates that is described in that topic.
Use the following steps to reset selected devices to factory default values.
