Scope:
This manual is valid for the RMS digital input module from firmware version V1.x. The low-order digit of the
manual is updated with each new release.
1 Overview
1.1 RMS System Overview
The Rotronic Monitoring System (RMS) is a network comprising various devices and the RMS server software.
The software is the heart of the system. It collects all measured data of the devices and saves it in the database.
The individual devices work as input modules (data loggers) and as output modules (displays, analog outputs,
switched outputs). The user can view the system data at any time on a PC, laptop or smart phone.

1.2 Device Overview
All devices can be configured as wanted as modules of the system. The following table shows all basic types of
the RMS devices. Almost all modules
1
have the following options:
Interface: Ethernet / Wireless
Housing: Wall housing / DIN top hat rail housing
Display Module
The display module can show any values from the
RMS network. Humidity, temperature and switch
states can be configured per software.
Standard Logger
Records the measured data of the digital HygroClip
HCD or other RMS probes. Stored in the ring
memory, the data are then sent to the server
software.
Output Module
Provides two analog voltage or current outputs or is
also available as variant with two solid-state relays in
order, for example, to switch alarm lamps.
Input Module
Records voltage or current signals from analog
devices such as particle counters, flow transmitters
or CO2 probes. For example:
HF5 transmitter (humidity & temperature)
AF1 transmitter (air flow)
CO2 transmitter (CO2)
PF4 transmitter (differential pressure)
Temperature Logger
The loggers can be equipped with various
temperature sensors (NTC, Pt100, Pt1000 or K-
element). This offers highest flexibility in use.
Mini Logger
A temperature logger with integrated or remote NTC
sensor. Instead of a temperature sensor, it is also
available with a switch input in order, for example, to
monitor door contacts.
Gateway
The gateway is the connecting element between
Ethernet and wireless network and forwards the data
flow from the loggers to the data centre.

1.3 RMS Digital Input Module
The digital input module saves all measured data based on event and sends it to the database via Ethernet.
The minimum signal pulse length is 100ms. Should the connection be lost, the module stores the data on the
internal memory to protect data integrity and fills up the data gaps when the connection has been restored. The
device has a battery so that logging of measured data is also ensured in the event of a failure in the external
power supply.
The device provides the following basic functions:
oTwo input channels (logic level 5 ... 24V or reed contacts)
oData logging of up to 75,000 measured values
oTransfer of the recorded data to the RMS software
oFirmware update
1.4 Power Supply
The digital input module has the following three power supply variants:
Two 3.6 V lithium thionyl chloride AA batteries
The power supply of the batteries suffices to carry out measurement and data storage and to operate
the wireless interface. Devices with an Ethernet interface must also have one of the following power
supplies.
24 VDC ±10 % / <100 mA
2
via terminals (V+ / V-)
Power over Ethernet (PoE), per standard IEEE 802.3af, Class 1
Note on the batteries:
The AA batteries are lithium thionyl chloride batteries available in the industrial trade. All RMS input modules
are designed for this type of battery. Only batteries of the same type or with identical characteristic values may
be used as replacement batteries.

1.5 Inputs / Outputs
Two channels are available for measuring a digital Boolean value each. The two inputs are switched either via
a logic level of 5 ... 24V or a reed contact. When the input status is changed, the device is activated, and
measured values are transferred to the database. This means the measurement of the digital inputs is event
triggered. The following table lists the main types of RMS devices:

1.6 RTCC (Real Time Clock Calendar)
The device has a real time clock calendar. The time is synchronized continuously when connected to the server.
1.7 Data Logging
The values of every measurement are saved in the memory with the time stamp. At a measurement interval of
one minute, it is possible to save data of more than one month, which corresponds to 70,000 measured values.
When the ring memory is full, the oldest values are overwritten. In case of server or network failures, lost of
measured data can only happen after one month.
The recording of measured data is always active when the device is integrated in a RMS-WEB system and
thus continuous measurements are carried out.
Following measured values are saved:
- time stamp
- actual status of the digital inputs

4.4 Behavior of the inputs
The measurement of the digital inputs are event-based, which means that the device transmits data to the
server only when a voltage level change is detected or the web service requests it at the set interval.
If the inputs are frequently changing, the maximum allowed switching frequency is 0.833 Hz, or a change can
be detected every 1.2s.
The inputs are independent, always active and register changes via the trigger. The device is not suitable for
pulses shorter than 1.2 seconds.
For the detection of the single pulses, the pulse must be at least 100ms long. The transfer to the web service
takes place with 2 different time stamps (1s offset).
Since, especially when using low voltages such as Reed, the input cable length shall be taken into account
(refer to the technical data).
4.5 Behavior in battery operation
The batteries serve to supply the device with power in the event of a failure in the external power supply. The
functionality of the device is restricted in battery mode. The device continues to measure and records all data
in the internal memory. The device cannot communicate via the Ethernet interface.
Lithium batteries of the type AA with 3.6 V are used, per section 1.4.1. Make sure they are inserted correctly.
The poles are marked on the battery and in the battery compartment.

5.4 Function Overview
Overview of the main software functions of the device
► Digital inputs
The device detects status changes at the input and sends these
to the RMS-WEB software.
The states can also be queried via Modbus TCP.
► Discovery
With Discovery it is possible to find devices in the subnet with
the RMS configuration software irrespective of their IP
configuration and to change their settings.
► IP configuration
The devices can have static or dynamic IP configurations. It is
recommended that you use a dynamic IP configuration
whenever possible.
If fixed IPs are used, the network topology must be considered
exactly.
► RMS Web Server settings
Every device has the server address and software path of the
RMS server software stored in it in order to build up
communication with the RMS server software.
The two parameters can be set with the RMS configuration
software:
Host: Address of the server with the RMS software
Server path: Server path where the server software is
installed.
► Audit Trail
The device stores events when changes are made to the
configuration.
► Save measured data
The measured values of every measurement are saved in the
internal ring memory (75,000 measured values). If the data
cannot be sent to the server software directly, they are kept in
the device and then sent later as soon as the connection to the
server software has been restored. Measurements are still
carried out in case of PoE power failure.
► Battery mode
If the external power supply (24 VDC / PoE) fails, the device
runs in battery mode. Measurements are still carried out at the
set interval and the data saved in the ring memory (75,000
measured values).
►Firmware update
The firmware of the device can be updated directly via the RMS
server software.
