Functions	Description
Analog Measurement	oThe measurement data are sent to the RMS WEB software at the fixed interval. oThe device sends to the measured data via Modbus TCP to the RMS WEB Service every fixed interval.
Logging function	oEvery measurement value and the time stamp is stored in the device memory. oIn case of data interruption, the data can be read out via the RMS-WEB software automatically afterward. NOTE: The device is not battery buffered. In case of power interruption, the device does not continue logging further data. Please use an external USP.
Audit Trail	oThe device stores changes of the device settings. oThese information are supplied to the RMS WEB Service.
Firmware Update	The firmware update can be done by the RMS WEB Service.
Discovery	The Discovery function can be used to find and configure devices within the subnet regardless of their IP configuration.
Use of a static IP Configuration	oIP Address oSubnet Address oGateway Server
Use of dynamic IP Address (DHCP)	DHCP Client can be turned on / off.
URL of the RMS WEB Service	Configuration of the URL for using the RMS WEB Service.
DNS Server	For the DNS, a primary and secondary DNS address can be set.

Power Variants

Power Supply: 24 VDC ±10 %, 4 W minimal, > 5 W Limited Power Source

PoE: 802.3af-2003, Class 1

Logging function

For each measurement, the measured values are stored in the memory with the associated time stamp. At a measuring interval of one minute, data can be stored for one month, which corresponds to approx. 44,000 measurements. If the memory is full, the oldest values are overwritten.

Indicator and Push-button

The device has a button, a green LED (PWR) and a multicolored LED (STS) for operation and display of the operating status. The button is used when the device is put into operation. The STS LED indicates the device status and whether a valid measurement was performed in the current measurement interval and the data could be sent to the monitoring system.

Indicator LED

When powered, the power LED is always on.

When paired, the status LED flashes every five seconds to indicate the status of the unit. The displayed device status is updated with each measurement and therefore always refers to the last measurement.

Blinking	Details
1 x green	Measurement successful, data transmission successful
1 x orange	Measurement successful, data transmission failed

Push-button

The device is controlled and configured via a server application. When a device is integrated into a system, the user must confirm he is the owner of the respective device by pressing on a key.

Whether a device is integrated in the system is primarily stored on the server. However, the device retains this information each time it communicates with the server and maintains the state in the event of a reboot or loss of connection. To remove the device from the system, it must be deleted from the server.

With a long keystroke, the local copy of the state can be discarded. Please note that the next time you communicate with the server, the state stored on the server will be adopted (if the device is integrated into the system). The function can be used as follows:

•The device is connected to a system which is not accessible and should now contact another server. In the integrated state, write-protection via Modbus TCP is active, which prevents settings from being overwritten. By a long keystroke this is deactivated and the new configuration can be written.

Operation external powered

Operation status	Push-button pressed
Pairing	Short time	Confirm pairing when connecting the device to the Rotronic Monitoring System. The LED flashes orange before the pairing can be confirmed. If the pairing is not confirmed, the device returns to offline mode after a certain time (determined by the RMS-WEB software).
Online	Long time (app. 4 to 5 sec.)	Discard the local pairing information. Note that pairing is always set by the server. If there is a connection to the server, the pairing is immediately taken over again.
