Description of operating modes
General | Parameter «RemoteStatus» is used to switch between the operating modes «LOCAL», | ||
| «REMOTE SETPOINT» and «FULLY REMOTE». The change is always accomplished | ||
| via the MOD bus. |
| |
| In the event the master fails or communication is lost, the RWF40... will switch to oper- | ||
| ating mode «LOCAL». The time for detecting a failure is set via the interface. | ||

³) | When the operating mode changes (e.g. LOCAL FULLY REMOTE), the relay |

| operating state of the plant. |
Dtt
Bus detection timer (value will also be maintained after a power failure)
The remote parameters are stored in RAM and will no longer be available after a power failure.
