Application and functions
1.3 Modes and operating modes
TeleControl
In the "TeleControl" mode, the RTU can send process data via the mobile wireless network
or via the LAN interface and an external router to a master station (see also "Communication
mode" below).
This mode is adopted when a communications partner (master station) is configured.
As an option, process data can be stored on an SD card. To do this logging must be enabled
in the WBM in "Operating mode".
Logging
In the "Logging" mode the RTU has no communications partner in the master station.
Instead, the RTU stores the process data.
This operating mode is adopted when logging must be enabled in the WBM in "Operating
mode".
In the "Logging" mode, the RTU requires an SD card where it can store the process data.
The stored process data can be read out from the SD card or sent via the mobile wireless
network or the LAN interface and an external router. Cyclic sending is possible by e-mail or
FTP. You can load the data on a PC via the WBM.
Operating modes
The RTU can adopt the following operating modes:
● Sleep mode
● Update mode
● Communication mode
● Service mode
Sleep mode
In the energy-saving standard operating mode the updating of the inputs and outputs, the
communications functions, the LEDs and the self check function (see section Other services
and properties (Page 30)) of the RTU are turned off.
The RTU interrupts the sleep mode in the following situations:
● Pressing the button "WKUP" and changing to the service mode
● Configured change to the update mode (WBM > Operating mode)"
With the inputs, other specific update cycles can be configured (WBM > "Tags").
● Configured change to the communication mode (WBM > Operating mode)"
● Pending diagnostics message with configured change to the communication mode (WBM
> "Diagnostics" > "Notifications")
