Warning concept
This manual contains information that you must observe for your personal safety and to
prevent damage to property. Warnings are presented in decreasing order of hazard level as
follows:
DANGER
Indicates a direct hazard for humans. Irreversible injuries or death will result if not
observed.
WARNING
Indicates a recognizable hazard for humans. Irreversible injuries or death may result if
not observed.
CAUTION
Indicates a recognizable hazard for humans or possible damage to property. May lead to
reversible injuries or damage to property if not observed.
ATTENTION
Information on potential damage to property. May cause damage to property if not
observed.
NOTE: Under “Note”, you will find tips, recommendations, and useful information on
specific actions and facts.
If several hazard levels occur, the warning for the highest level is always used. If the
triangle warning against personal injury is used in a warning, then a warning against
property damage can also be added to the same warning notice.

3Product information
HUB-MRT100 is a USB stick that stores and plays back the system clock time on the one
hand and process data on the other. HUB-RT100 stores only the system clock time.
Both add-on modules have been specially developed for use in industrial environments and
ensure the correct system time especially at locations with frequent disturbances of the
electricity supply. HUB-MRT100 additionally has an F-RAM, so that the last written process
data can be saved and replayed.
3.1 Principle of operation
The HUB-RT100 or HUB-MRT100 is plugged into the USB interface of an in.hub gateway, e.g.
the HUB-GM200.
If SIINEOS is installed on the gateway, then you can synchronize the system time via the
software interface. See Setting the time in SIINEOS, page 8.
However, it is also possible to operate the stick with a different system software and a
third-party hardware. For more information, see chapter OPTIONAL: Integrating HUB-
(M)RT100 into Linux, page 11.

Assembly and commissioning
8
4Assembly and commissioning
Observe the applicable safety and accident prevention regulations for specific areas of
application, e.g. the Machinery Directive.
4.1 Plugging in the HUB-(M)RT100 and putting it into operation
1. Plug the HUB-MRT100 or the HUB-RT100 into the USB1 or USB2 port of your
in.hub gateway.
If there is not enough space in the control cabinet, you can also use a USB extension
cable or a USB hub.
As soon as the stick is plugged in, the LED in the stick lights up to indicate that the
external real-time clock is operational.
2. Leave the stick plugged in permanently.
Changing the battery becomes necessary when the system time no longer matches the
local time with the HUB-(M)RT100 connected.
See chapter Changing the battery, page 9.
4.2 Setting the time in SIINEOS
HINT: The SIINEOS user documentation can be found in the in.hub download portal at
https://download.inhub.de/siineos/. Check there regularly to always have the latest
documentation at hand.
1. Log in to SIINEOS with your user data and navigate to System > Date & time.
Fig. 1: System > Date & time (example)
2. First click Synchronize time via browser now to ensure that the gateway's time is
synchronized with the computer.

3. Click Set hardware real-time clocks to transfer the system clock time to the external
real-time clock.
4. Leave the stick permanently plugged into the device, so that in case of power supply
interruptions the gateway can always obtain the time from the HUB-(M)RT100 again.
4.3 Changing the battery
Note that the operating time of the HUB-(M)RT100 depends individually on the ambient
conditions.
The service life guaranteed by the manufacturer is at least 5 years but can be up to 10
years under optimum environmental conditions.
CAUTION Damage to components due to electrostatic charge!
Avoid touching electronic contacts and components directly.
Use e.g. ESD-compatible clothing or other measures to protect
against charging.
1. Unscrew the 2 screws from the housing using a cross-head screwdriver and remove the
housing.
Fig. 2: Unscrew housing
2. Loosen the 4 screws on the board with the cross-head screwdriver and remove the
other part of the housing.

3. Push the battery out of the battery compartment with a blunt, narrow item and insert a
new battery.
The label on the battery points upwards.
Fig. 4: Change battery
4. Put the board back into the housing and screw first the board with the 4 short screws
and then the housing with the 2 long screws.

5OPTIONAL: Integrating HUB-(M)RT100 into Linux
The two add-on modules HUB-MRT100 and HUB-RT100 are proprietary developments of
in.hub, for which no standard drivers are available to use them out-of-the-box.
In order for the stick to be recognized by your individually developed system software, you
must perform the following steps:
1. Integrate chip driver mcp2221.
2. Integrate RTC driver m41t80.
3. Only HUB-MRT100: Integrate F-RAM.
Detailed information for Linux can be found at https://github.com/in-hub/hub-mert100-
linux.
This repository provides the driver source code or patches for the Linux kernel.
HINT: This information is intended exclusively for software developers who have
programmed the system software themselves.
