The CPU Lock feature of Logix 5000 controllers causes this service request
to return a General Status 0x10, Device State Conflict when the controller is
password locked. In this state, controller memory can not be altered.
Rockwell Automation suggests after receipt of the Device State Conflict for
the first time, the client application should refresh the tag information one
time. The client application should refresh again if the connection lost. The
client application should reconnect after receipt of General Status 0x05, or a
successful response to the service that indicates the CPU is unlocked.
