Note: Detailed block diagrams of the most common power supply units are provided in
chapter "Technical details about the energy supply" on page 62.
4.6 Intended use
The portable, freely programmable measurement instrument is designed for determining, processing and
transferring measurement data acquired via various industrial interfaces. The device can operate without
mains power. The measured and recorded data is stored on a non-volatile memory medium. The stored data
can be sent to a central server via LoRaWAN for further processing. The maximum permissible limit values
specified in chapter "Specifications" on page 13 must be observed. The manufacturer shall not be liable for
any operational cases that deviate from these limit values and have not been approved by the manufacturer in
writing.
Note: This device is exclusively intended to be used for the purposes as described before. Any other
use or use beyond what is specified or a modification of the device shall be deemed to be not for the
intended purpose and is not permitted without the express written consent of the manufacturer. The
manufacturer shall not be held liable for any damages that may result from such unauthorised use or
modification. The operator alone bears the associated risk.
Note: The manufacturer is not liable for data loss of any kind.
4.7 General product information
The device is a compact, freely programmable device for determining, processing and transferring
measurement data.
The following interfaces are available for recording measurement data:
l
4 universal inputs that can be operated in various analogue and digital modes.
1)
l
An interface for connecting a PT100 or PT1000 including automatic detection of which type is being
used
2)
l
One RS232 interface
3)
l
One RS485 interface
1) 4)
The myDatalogEASY IoTmini is also equipped with internal sensors (internal housing temperature and air
humidity in the housing), 3 switchable voltage outputs to supply the sensors and an isolated switch contact to
directly control an actuator. For one of the switchable sensor supplies the device logic can be used to vary the
output voltage (see "Vsens_On()") in the range of 5...24V . The output voltage for the other 2 switchable
sensor supplies is 3,3V and cannot be changed. The isolated switch contact can be operated in different
modes (digital, frequency, PWM, pulse, pulse/min.).
The customer can create their own application via the rapidM2M Studio (see "rapidM2M Studio " on page
79). During development the part of the application that needs to be installed on the device (i.e. the device
logic) is loaded into the myDatalogEASY IoTmini via the USB interface. For applications that are provided via
the rapidM2M Store installation of the device logic is performed via the USB connection in the course of
connecting the site with the myDatalogEASY IoTmini . The device logic enables access to the serial
interfaces (RS232
3)
and RS485
3)
) thus providing the customer with the option to connect to almost all of the
devices and sensors that are compatible with these interfaces and to implement the corresponding
communication protocols.
The myDatalogEASY IoTmini provides the customer with a memory area for their data (3MB ) as well as 10
independent memory blocks each with 4000 Byte for the configuration data. In addition to the 4 registration
memory blocks each with 1kB , that are saved in the flash, the myDatalogEASY IoTmini has another one that
