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 &quot;Specifications&quot; 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:
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)
3)
l One RS232 interface
1) 4)
l One RS485 interface
l
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 &quot;Vsens_On()&quot;) 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 &quot;rapidM2M Studio &quot; 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
22
Rev. 01
Chapter 4 General specifications
can optionally be initialised via the &quot;rM2M_RegInit()&quot; function and that is saved in the RAM. Its size can be
specified during initialisation, although it is limited to a maximum of 1kB . The registration memory blocks are
assigned to predefined purposes and are designed for storing device-specific data (see &quot;Registration
memory blocks&quot; on page 32).
Recorded measurement data can be sent to a central myDatanet server via LoRaWAN5) for further
processing.
Synchronisation of the configuration and registration data with the server, however, is only possible via the
USB connection .
1) The universal inputs 3 and 4 are only available if the RS485 interface is not used.
2) In order for the external temperature sensor to be used, the chargeable feature &quot;Activation code temperature
input(300542)&quot; must be unlocked or order option &quot;Feature activation temperature input (300732)&quot; is required.
3) In order for the RS232 interface to be used, the chargeable feature &quot;Activation code RS232 (300541)&quot; must be unlocked
or order option &quot;Feature activation RS232 (300731)&quot; is required.
4) In order for the RS485 interface to be used, the chargeable feature &quot;Activation code RS485 (300540)&quot; must be unlocked
or order option &quot;Feature activation RS485 (300730)&quot; is required.
5) In order to transfer the data via LoRaWANthe order option &quot;Feature activation LoRa (300971)&quot; is required.

times. The safety instructions contained therein must be observed.
WARNING:
It is strictly prohibited to disable the safety equipment or modify its mode of operation.
4.9 Installation of spare and wear parts
Be advised that spare and accessory parts that have not been supplied by the manufacturer have also not
been inspected or approved by the manufacturer. The installation and/or use of such products can possibly
have a negative impact on the specified constructional properties of the device. The manufacturer shall not be
liable for any damages that arise from the use of non-original parts and non-original accessory parts.
4.10 Storage of the product
For safekeeping of the myDatalogEASY IoTmini , ensure that all relevant data was transferred to the
myDatanet server. If necessary, initiate a transmission directly on the device using the solenoid contact (see
&quot;Solenoid switch&quot; on page 71), if you have included this in your Device Logic, and then check again to see
whether all of the relevant data has now been transferred. If your device does not include the option to initiate
the transmission of temporarily stored measurement data, you may have to wait until the next scheduled data
transmission for all of the data to be sent to the myDatanet server. Remove the power supply unit before
disconnecting the cables and antenna. If possible, switch off the supply or charging voltage before
disconnecting the cables from the V IN and GND clamps (see &quot;Connecting the sensors, actuators and power
supply&quot; on page 50). Store the myDatalogEASY IoTmini and power supply unit in the original packaging.
The configuration and most recently determined data are retained. The system time also continues to run
thanks to the hardware real-time clock equipped with its own buffer battery. This means that a valid time basis
is available immediately following recommissioning (see &quot;Technical details about the system time&quot; on page
65).
4.11 Warranty

l
Directly via LoRaWAN
Indirectly, by initially reading the data from the device via the DeviceConfig configuration program using
the USB connection and then using the PC’s Internet connection to transfer the data to the server
For transferring the data from the myDatalogEASY IoTmini to the customer-specific server only one option is
available:

Application (device logic)
The firmware of the myDatalogEASY IoTmini only manages the synchronisation of the measurement
data and configurations between the myDatalogEASY IoTmini and myDatanet server. The application
created by the customer must record the measurement values and create the data blocks that are to be
saved. The data blocks, on the other hand, are stored by the firmware of the myDatalogEASY IoTmini
(see &quot;rM2M_RecData()&quot;).
l
Data Descriptor
The basic function of the myDatanet server is limited to synchronisation of the measurement data
channels (&quot;histdata0&quot; - &quot;histdata9&quot;) and configuration blocks (&quot;config0&quot; - &quot;config9&quot;) between the
myDatalogEASY IoTmini and server. The Data Descriptor defined by the customer must divide the
measurement data channels and configuration blocks into the individual data fields.
l
Customer-specific server with web interface for the clients (optional)
It can be used to create an individual web interface for the clients. Two options are possible depending
on which source is used to obtain the data:
l
l
Customer-specific server that reads its data via the API interface (see &quot;API&quot; on page 187) from
the myDatanet server.
Customer-specific server that receives its data via LoRaWAN connection from the
myDatalogEASY IoTmini .
5.1 Recommended procedure
5.1.1 Development of M2M/IoT application
It is recommended to start with the definition of the Data Descriptor (see &quot;Data Descriptor &quot; on page 185)
when developing a M2M/IoT application. It specifies the various data structures (measurement data,
configurations, etc.) that are valid for the Device Logic as well as the myDatanet server. The definitions of the
Data Descriptor also apply for accessing the data of the myDatanet server via the API.
The information type should be taken into consideration when assigning the data to the relevant containers
(&quot;histdata0&quot; - &quot;histdata9&quot; or &quot;config0&quot; - &quot;config9&quot;). The &quot;histdata0&quot; - &quot;histdata9&quot; containers should be used for
time series. If there is measurement data that will be generated frequently and data that will only be
generated rarely, it is recommended to use two different containers (e.g. &quot;histdata0&quot; for the frequently
generated and &quot;histdata1&quot; for the rarely generated). Similar also applies to the configuration data, for which
the &quot;config0&quot; - &quot;config9&quot; containers are provided. When it comes to the configuration data, it is recommended
to take a grouping based on logical context into consideration in addition to the frequency of change.
Note: A well thought out selection of the containers helps to reduce the required data volume and
associated costs.
5.2 Functionality of the internal data memory
Structure
Circular buffer
Total size
3MB
Number of sectors
8
Sector size
393.216 Byte
Rev. 01
29
The internal data memory of the myDatalogEASY IoTmini is designed as a circular buffer with 8 sectors. If the
entire memory (3MB ) is full, the sector with the oldest data is deleted fully before new data can be saved in
this sector again. This means that the internal data memory comprises at least 2,625 MB of valid data and a
maximum of 3MB .
For this reason, it is recommended to coordinate the data transmission and record interval in such a way that
a maximum of 2,625 MB has to be recorded between two transmissions. If it can be expected that individual
transmissions fail due to poor network coverage, this must also be taken into consideration when calculating
the data volume to be saved. Additionally, it must be noted that the system-related overhead is 10 Byte per
data record and that the first 8 Byte of each sector are reserved for the internal memory management. The 10
Byte overhead already includes the timestamp, so it does not have to be taken into account when calculating
the size of the entire record. If there is not enough free space in a sector to save the entire data record, the
data record is written to the next sector. This means that a data record is not written over the sector limits.
Note:
Additional explanation regarding the functionality of the circular buffer
Data memory after the first data is recorded:
Data memory once 3MB has been recorded
Data memory if further data is recorded once 3MB has already been recorded
Note:
Additional explanation on calculating the data volume to be saved:
To provide a clear and simple overview, the following example assumes that the sectors can only record two
complete data records.
1) Free memory in sector 1 is not enough to record a full data record (overhead + data).

5.3 Memory organisation
Organisation of the myDatalogEASY IoTmini memory
1)This memory block is only available if it was initialised via the &quot;rM2M_RegInit()&quot; function.
The size of the PAWN binary must not exceed 256kB for the transmission to the myDatalogEASY IoTmini . If
necessary, the data area of the PAWN binary can be compressed using a compiler instruction (#pragma
amxcompress &lt;0-3&gt;). The PAWN binary (256kB ), 10 configuration blocks (4000 Byte each), 4 registration
memory blocks (1kB each) and measurement data (3MB ) are stored in the flash memory of the
myDatalogEASY IoTmini . To execute via the PAWN script engine, the data area of the PAWN binary is
decompressed, if necessary, and copied to the RAM. The maximum size for the decompressed data area of
the PAWN binary in the RAM is 64kB . The optional registration memory blocks (e.g. REG_APP_STATE)
which can be initialized via the &quot;RM2M_RegInit ()&quot; function are also stored in RAM.
Rev. 01
31
5.4 Error handling
The following transmission mechanisms have been integrated in the firmware to ensure that problems with
the Device Logic can be diagnosed and resolved remotely. In the event that there is no Device Logic, a
connection to the myDatanet server is established every 24h . This backup interval is set to 1h if an existing
Device Logic has been deactivated due to an error being detected by the system. The &quot;Interval &amp; wakeup&quot;
connection type is activated in both cases, which enables a connection to be initiated via the interface of the
myDatanet (see &quot;myDatanet Server Manual &quot; 805002).
5.5 Registration memory blocks
In addition to 4 1kB blocks, that are saved in the flash, another one, that is saved in the RAM, can optionally
be initialised via the &quot;rM2M_RegInit()&quot; function. Its size can be specified during initialisation, although it is
limited to a maximum of 1kB . The registration memory blocks provide the option of storing device-specific
data and synchronising it with the myDatanet server. The blocks only differs with regard to their access
options and storage location. This results in predefined intended uses that are described in the following
table:

Note: It is also possible to write in the memory blocks as part of the production process via the local
interfaces (USB and both UART). However, an agreement must be reached with the manufacturer to
receive information about this (see &quot;Contact information&quot; on page 209).

&quot;rM2M_RegDelValue()&quot; and &quot;rM2M_RegDelKey()&quot; functions are available for accessing the registration
memory blocks.
5.5.1 REG_SYS_FLASH
If the site that is linked to the device was created from an application template (see myDatanet Server Manual
805002), the registration memory block contains the following fields:
latestAppVersion
The latest available version of the application template installed on the device [16-bit unsigned]
installedAppVersion
Version of the application template currently installed on the device [16-bit unsigned]
appId
Application ID of the application installed on the device [max. 50 characters]
5.5.2 REG_APP_OTP
By saving the &quot;Product Identity Profile&quot; (PIP) in this registration memory block, the functions described in the
following can be initiated on the myDatanet server. The PIP consists of the following fields:
pipCustomer
Name of the customer to whom the site should be assigned [2-50 characters].
pipCtx
Name of the site that should be created/used [2-50 characters].
pipAppId
Application ID of the application template from which the site should be created [max. 50 characters].
pipAppVer (optional)
Version of the Device Logic currently installed on the device (e.g. &quot;01v005&quot;) [6 characters].
pipCtxAutocreate (optional)
Indicates whether the site (if it does not exist yet) should be created (&quot;0&quot; or &quot;1&quot; must be saved as the
string)
&quot;0&quot;: creation of a new site is not permissible
l &quot;1&quot;: new site can be created (default)
l
If the myDatanet server receives a PIP, the two basic scenarios are differentiated:
l
There is no site with the name specified in the &quot;pipCtx&quot; field:
The new site is only created if the customer and application template were found on the myDatanet
server and &quot;pipCtxAutocreate=1&quot; or the field is missing.
l
A site with the name specified in the &quot;pipCtx&quot; field was found on the server:
In this case, the &quot;pipCtxAutocreate&quot; and &quot;pipCustomer&quot; fields are not relevant. The device is assigned
to the site, even if it is located within a different customer, if the application ID in the &quot;pipAppId&quot; field and
that of the found site match. The device is moved to the relevant customer for this purpose. The
allocation of the existing device is deallocated if a device is already assigned to the site. The existing
device is moved to the customer's pool.

6.4.1 Transporting power supply units
WARNING:
With the exception of the PSU DC (300529), the power supply units required to operate the
myDatalogEASY IoTmini are classified as hazardous goods due to the installed
rechargeable batteries or battery packs for which the following conditions must be
observed during transport.
The guidelines that must be observed when transporting hazardous goods are dependent on the selected
transport route and are designed as follows:
Transport by road: ADR Directive
Transport by air: IATA guideline
l Transport by rail: RID guideline
l Transport by ship: IMDG guideline
l
l
36
Rev. 01
Chapter 6 Storage, delivery and transport
The following parties must observe these guidelines:
Shipping and packaging company
l Haulage contractors
l Air carriers and ground handling service providers (only if the IATA guideline is applied)
l Security personnel (particularly if the IATA guideline is applied)
l
When it comes to transporting hazardous goods, the most important tasks of the shipping and packaging
company are:
Classification / identification
Packaging
l Marking and labelling (e.g. transport stickers)
l Documentation (e.g. ADR transport documents or Dangerous Goods Declaration)
l
l
The energy stores of the power supply unit are lithium batteries. The following points must therefore be
observed in conjunction with transporting lithium batteries:
l
l
l
Type of lithium battery
l Lithium ion battery
l Lithium metal battery
Battery energy content
l If the energy content is within the &quot;exempt&quot; level, this will make the transportation process easier.
l If the energy content is above the &quot;exempt&quot; level, the battery is classed as a &quot;complete&quot;
hazardous material in accordance with the relevant guideline.
Scope of the delivered package
l Battery packed individually
l Battery packed with or in the equipment
Other matters that must be taken into consideration during transport preparation and processing:
Net weight per package

7.4.1 Information on preventing electrostatic discharges (ESD)
Important note: Maintenance procedures that do not require the device to be connected to the
power supply should only be performed once the device has been disconnected from the mains
power supply to minimise hazards and ESD risks.
The sensitive electronic components inside the device can be damaged by static electricity, which can impair
the device performance or even cause the device to fail. The manufacturer recommends the following steps
to prevent any damage to the device caused by electrostatic discharges:
Discharge any static electricity present on your body before handling the electronic components of the
device (such as circuit boards and components attached thereto). To do this, you can touch a grounded
metallic surface such as the housing frame of a device or a metal pipe.
l Avoid any unnecessary movements to prevent the build-up of static charges.
l Use antistatic containers or packaging to transport components that are sensitive to static.
l Wear an antistatic wristband that is grounded via a cable to discharge your body and keep it free of
static electricity.
l Only touch components that are sensitive to electric charges in an antistatic working area. If possible,
use antistatic mats and work pads.

Note: The RS485 interface corresponds to standard EIA-485.
The RS485 interface of the myDatalogEASY IoTmini includes an input common mode range that covers the
full area specified for RS485 (-7V...+12V). Higher voltages damage the interface. Differential signals of more
than +/-200mV within the specified input common mode range are detected correctly. In send mode, the
output signal is in the range of 1,5...3,3V .

Note: Additional explanation regarding the connection of two RS485 bus participants
Schematic diagram: Connection of two RS485 bus participants
A problem occurs if there is no connection between the GND potentials of the sender and recipient. A common
mode voltage (VCM) occurs in this case. The GND potential difference must not exceed max. +/- 7V . Higher
voltages will damage the interface. Temporary overvoltages (ESD, EFT and surge) are, however, absorbed by
protective circuits.
Note: The common mode input voltage range of -7V...+12V specified for the RS485 is determined from the
max. permissible GND potential difference (+/- 7V ) and the max. permissible output voltage range of 0...5 V for
RS485.
7.5.6 Technical details about the RS232 interface
Note: The RS232 interface of the myDatalogEASY IoTmini is compatible with standard TIA/EIA232-F.
The output drivers are protected against overloading and are not damaged by a short circuit to the GND or +/15 V. The inputs are equipped with a 5 kΩ load resistance.

7.5.7 Technical details about the USB interface
The connection to a PC is established via the USB slave interface. It is only designated for the communication
with the web-based development environment rapidM2M Studio or the DeviceConfig configuration program.
It is not possible to access the USB interface via the device logic. A detailed description of the rapidM2M
Studio web-based development environment is provided in chapter &quot;rapidM2M Studio &quot; on page 79.
Explanations regarding the functionality of the DeviceConfig configuration program is provided in the manual
for the DeviceConfig (&quot;myDatanetDeviceConfig Manual &quot; 805004).
Access to the web-based development environment rapidM2M Studio is included in the Microtronics Partner
Program, for which you can register free of charge at the following address:
https://partner.microtronics.com
The DeviceConfig configuration program can be downloaded free of charge from the following website:

7.5.9 Technical details about energy management
The Device Logic execution is only stopped if the internal supply voltage falls below 2,9V and the
myDatalogEASY IoTmini switches to energy saving mode in which only the charge control is active. In this
case, the charge control tries to charge the rechargeable battery up to 3,8V . The &quot;UV_LOCKOUT&quot; log entry
is also entered in the device log when activating energy saving mode. The rechargeable battery of the power
supply unit can be charged up again if the device is in energy saving mode and an external supply or charging
voltage (V IN) is connected. Otherwise the myDatalogEASY IoTmini remains in this energy saving mode until
the rechargeable battery is completely discharged.
Energy saving mode is terminated and Device Logic execution is activated again, once the rechargeable
battery voltage exceeds 3,2V when recharging.
Rev. 01
61
When an external supply or charging voltage (V IN) is used, the charge control ensures that the rechargeable
battery of the power supply unit is charged. The following operating states are possible:
l
Active energy saving mode (i.e. Device Logic inactive) or no Device Logic installed:
The charge control tries to charge the rechargeable battery to 3,8V or to maintain the voltage at this
level.
l
Device Logic active but the charge control was not configured via the &quot;PM_SetChargingMode&quot;
function:
The charge control is activated and the rechargeable battery is charged to the maximum voltage if the
state of charge of the rechargeable battery for the power supply unit falls below 50%. The charge
control is then deactivated again. This is designed to optimise the service life of the rechargeable
battery.
l
Device Logic active and the charge control was configured via the Device Logic:
The functionality of the charge control can be configured via the &quot;PM_SetChargingMode&quot; function.
There are three options available:
l
l
l
PM_CHARGING_OFF: Charge control deactivated
PM_CHARGING_NORMAL: The charge control is activated and the rechargeable battery is
charged to the maximum voltage if the state of charge of the rechargeable battery for the power
supply unit falls below 50%. The charge control is then deactivated again. This is designed to
optimise the service life of the rechargeable battery.
PM_CHARGING_SOLAR: The rechargeable battery of the power supply unit is charged to the
maximum voltage if the supply or charging voltage V IN exceeds 16V . The charge control then
remains deactivated for 12 hours unless the state of charge of the rechargeable battery for the
power supply unit drops below 95%. This charge strategy is recommended if a solar field is used
to charge the rechargeable battery.
The charge control reads out any additional information that is required, such as the maximum voltage and
ambient temperature at which charging is permitted, directly from the memory of the power supply unit. In
both charge strategies, recharging is only completed if the ambient temperature does not exceed the
permissible range of the charging temperature. The permissible charging temperature is specified in the
factsheet for the relevant power supply unit. Chapter &quot;Power supply units&quot; on page 204 contains an overview
of the temperature ranges of the power supply units.

7.5.11 Technical details about the system time
The myDatalogEASY IoTmini is equipped with a hardware real-time clock that has its own buffer battery with
an expected service life of &gt;10 years. The system time continues to run even if the power supply unit is
removed. This means that following recommissioning, valid time stamps for the measurement and log data
can be generated immediately. Additionally, the system time is synchronised with the server each time a
connection to the myDatanet server is established.

8.1 User information
Before you connect the myDatalogEASY IoTmini and place it into operation, you must observe and comply
with the following user information!
This manual contains all information that is required for using the device.
Is intended for technically qualified personnel who have the relevant knowledge and experience in the area of
measurement technology.
Read this manual carefully and completely in order to ensure the proper functioning of the
myDatalogEASY IoTmini .
Contact Microtronics Engineering GmbH(see &quot;Contact information&quot; on page 209) if anything is unclear or if
you encounter difficulties with regard to installation, connection or configuration.
8.2 Applicable documents
In addition to this operating instructions, additional instructions or technical descriptions may be required for
the installation, commissioning and operation of the entire system.
These instructions are enclosed to the respective additional devices or sensors or are available for download
on the Microtronics website.
8.3 General principles
The entire measurement system may only be placed into operation after completion and inspection of the
installation. Study the manual thoroughly before placing into operation to prevent faulty or incorrect
configuration.
Utilise the manual to familiarise yourself with the operation of the myDatalogEASY IoTmini and the input
screens of the myDatanet server before you begin with the configuration.
8.4 Commissioning the system
Note: It is recommended that the myDatalogEASY IoTmini is first placed into operation in the office before
mounting the device permanently at the place of use. During this process, you should create a site for the later
operation on the myDatanet server (see &quot;Creating the site&quot; on page 81) and determine a site configuration
(including Data Descriptor and Device Logic) (see &quot;Site configuration&quot; on page 72). If you create the site based
on an IoT application (see &quot;myDatanet Server Manual &quot; 805002), the Data Descriptor and Device Logic are
taken from the IoT application and do not need to be defined separately. Take the opportunity to get to know the
functions of the device in a stable environment. You can also use suitable test signals to simulate the sensors
to establish the optimum configuration of the myDatalogEASY IoTmini prior to its actual first use. This reduces
the amount of time required for on-site installation to a minimum.
Rev. 01
67
The following work should be completed in the office before you go to the future location of the device:
1. If necessary, create a customer on the myDatanet server (see &quot;myDatanet Server Manual &quot; 805002).
2. Within the selected customer, create a site/application for operation on the myDatanet server (see
&quot;Creating the site&quot; on page 81).
Note: A &quot;rapidM2M &quot; type site or a site based on an IoT application that is compatible with the
&quot;rapidM2M &quot; site type must be created to operate the myDatalogEASY IoTmini .
3. Configure the created site/application according to your requirements (see &quot;Site configuration&quot; on page
72). If the site was not created based on an IoT application, you must determine the Data Descriptor
and Device Logic via the &quot;Control&quot; configuration section (see &quot;Control&quot; on page 73).
4. Connect the antenna (see &quot;Connecting the LoRa antenna&quot; on page 54). The antenna is not included in
the scope of delivery and must be ordered separately.
5. Establish a connection so that the configuration of site is transferred to the myDatalogEASY IoTmini . If
no script has been loaded in the device yet, this can be achieved by inserting the power supply unit as
described in the chapter &quot;Assembling the myDatalogEASY IoTmini &quot; on page 39. If a Device Logic has
already been loaded in the device, execute the operations provided in the Device Logic to trigger the
establishment of a connection.
Note: Note that all power supply units with an integrated and rechargeable energy store are delivered
with a maximum charge of 30% in accordance with applicable transport regulations and must therefore
be fully charged before being used for the first time (see &quot;Charging the power supply unit&quot; on page 191).
Note: If you are using a power supply unit without an integrated energy store, the external supply or
charging voltage must be connected before inserting the power supply unit. Details on this are provided
in the chapter &quot;Connecting the sensors, actuators and power supply&quot; on page 50.
Note: You can also skip this step, as a connection must also be initiated during the installation on site,
which transfers the configuration to the myDatalogEASY IoTmini at the same time.

Chapter 8 Initial Start-Up
The following work is completed directly at the location of the device:
8. Complete all of the steps detailed in the chapter &quot;Assembling the myDatalogEASY IoTmini &quot; on page
39.
9. Check whether the connection to the myDatanet server has worked correctly (see &quot;Testing
communication with the device&quot; on page 69).
8.5 Testing communication with the device
1. Create a site for operation on the myDatanet server (see &quot;Creating the site&quot; on page 81).
Note: A &quot;rapidM2M &quot; type site or a site based on an IoT application that is compatible with the
&quot;rapidM2M &quot; site type must be created to operate the myDatalogEASY IoTmini .
2. Configure the created site/application according to your requirements (see &quot;Site configuration&quot; on page
72). If the site was not created based on an IoT application, you must determine the Data Descriptor
and Device Logic via the &quot;Control&quot; configuration section (see &quot;Control&quot; on page 73).
3. Connect the antenna (see &quot;Connecting the LoRa antenna&quot; on page 54). The antenna is not included in
the scope of delivery and must be ordered separately.
4. Establish a connection. If no script has been loaded in the device yet, this can be achieved by inserting
the power supply unit as described in the chapter &quot;Assembling the myDatalogEASY IoTmini &quot; on page
39. If a Device Logic has already been loaded in the device, execute the operations provided in the
Device Logic to trigger the establishment of a connection.
Note: Note that all power supply units with an integrated and rechargeable energy store are delivered
with a maximum charge of 30% in accordance with applicable transport regulations and must therefore
be fully charged before being used for the first time (see &quot;Charging the power supply unit&quot; on page 191).
Note: If you are using a power supply unit without an integrated energy store, the external supply or
charging voltage must be connected before inserting the power supply unit. Details on this are provided
in the chapter &quot;Connecting the sensors, actuators and power supply&quot; on page 50.

5. Wait until the measurement instrument list indicates that the device is connected to the server (rotating
arrows).
With the exception of the &quot;Online&quot; connection type (see &quot;rM2M_TxSetMode()&quot;), the time during which
the myDatalogEASY IoTmini is connected to the server is very short. It can therefore also be checked
whether the time stamp of the last connection (under the green status symbol) has been updated.
The following steps are only necessary, if you simultaneously want to test the measurement value acquisition
and data transmission.
6. Complete all of the steps detailed in the chapter &quot;Assembling the myDatalogEASY IoTmini &quot; on page
39. This includes connecting the sensors.
Important note: All wiring work must be performed in the de-energised state.
7. You can use the &quot;Reports&quot; of the myDatanet server to check the data transmission (see &quot;myDatanet
Server Manual &quot; 805002). The configuration of the Data Descriptor (see &quot;Data Descriptor &quot; on page
185) is required for this purpose.
8. Once you have completed the necessary preparations, initiate a transmission directly on the device if
you have included this in your Device Logic. If you have not included an option to trigger a transmission,
wait for the next scheduled data transmission.
9. Evaluate the incoming data.

Chapter 10 rapidM2M Studio
Note: The web-based development environment rapidM2M Studio is being developed continuously which can
lead to slight changes to the appearance of the program compared to the screenshots used in this manual.
10.1 General
Access to the web-based development environment rapidM2M Studio is included in the Microtronics Partner
Program, for which you can register free of charge at the following address:
https://partner.microtronics.com
It is a web-based IDE that is designed to support customers with the creation of IoT applications for the
myDatalogEASY IoTmini . This covers the entire development process - from editing the source code, to
testing as part of the creation process to publishing the finished IoT application in the rapidM2M Store . All
elements which make up an IoT application are summarised in a single project. The elements are:
Device logic: intelligence installed locally on the myDatalogEASY IoTmini
Backend logic: intelligence installed on the myDatanet server
l Data descriptor: describes the structure of the data (measurement data, configurations, etc.), that is
exchanged between myDatalogEASY IoTmini , myDatanet server and external systems (e.g. front
ends connected via REST API).
l Portal view: Simple front end that is supplied by the myDatanet server (e.g. for fast prototype
development and/or provision of administrative data)
l
l
In addition to the dashboard for managing the projects, the rapidM2M Studio consists of two main interfaces:
l
l
CODEbed: Editing and compiling the source codes
TESTbed: Testing the IoT application in conjunction with a locally connected device and the
associated back end i.e. the myDatanet server
The sharing function implemented in the rapidM2M Studio enables developers from different disciplines
(firmware programmers, cloud developers, web designers, etc. ) to create an IoT application together as well
as to share projects and libraries with colleagues and the community. The integrated version management
also ensures controlled distribution of updates of an IoT application across the entire chain from the
rapidM2M Studio to the rapidM2M Store to the sites (that were created based on the IoT application) to the
myDatalogEASY IoTmini .

Chapter 12 Device Logic (Pawn)
Chapter 12 Device Logic (Pawn)
12.1 General
The following chapter describes the functionality of the device logic. The programming language used is
&quot;Pawn&quot; (previously SMALL), a scripting language similar to C that runs on embedded systems.
Additional, more detailed information is provided on the developer's website:
http://www.compuphase.com/pawn/pawn.htm.
There are several ways to create a device logic for the myDatalogEASY IoTmini :
Direct entry in the &quot;Device Logic&quot; input field in the &quot;Control&quot; configuration section
Upload of a previously created binary file (*.amx) to the myDatanet server
l Usage of the CODEbed of the web-based development environment rapidM2M Studio
l
l
12.1.1 Direct entry of a device logic
The device logic is entered via the &quot;Control&quot; configuration section (see &quot;Control&quot; on page 73) of the input
screen for configuring the site. &quot;Pawn&quot; must be selected as the &quot;Device Logic Type&quot; so that the
myDatalogEASY IoTmini interprets the commands entered under &quot;Device Logic&quot; as a pawn script.
12.1.2 Uploading a binary file
If the &quot;Upload a compiled device logic&quot; entry was selected via the &quot;Device logic source&quot; list selection in the
&quot;Control&quot; configuration section (see &quot;Control&quot; on page 73) of the input screen for configuring the site, a binary
file that was, for example, previously created via the web-based development environment rapidM2M Studio
(see &quot;rapidM2M Studio &quot; on page 79) can be uploaded to the myDatanet server. This is then loaded into the
myDatalogEASY IoTmini during the next connection. When using this method, &quot;Pawn&quot; must also be selected
as the &quot;Device Logic Type&quot; so that the myDatalogEASY IoTmini interprets the commands as a pawn script.
12.1.3 Using the CODEbed of the web-based development environment rapidM2M
Studio
The CODEbed is one of the two main interfaces of the web-based development environment rapidM2M
Studio . The CODEbed serves to create and compile source codes for all elements (device logic, backend
logic, data descriptor and portal view) of an IoT application. The functional scope of the rapidM2M Studio also
includes transfer of the compiled device logic into the myDatalogEASY IoTmini via a USB connection and
copying of the data descriptor to the development site with which the myDatalogEASY IoTmini is linked.

Note: Additional explanation on the type of storage:
If Bit 0 was not set (default), the non-volatile storage of the configuration memory block in the FLASH is
initiated when the &quot;rM2M_CfgWrite&quot; function is called.
If Bit0 was set (Bit0 = RM2M_CFG_VOLATILE), the configuration memory block is saved in the RAM in
a volatile manner when the &quot;rM2M_CfgWrite&quot; function is called. This option is recommended if the data
in the configuration memory block changes frequently as this will reduce the number of flash write
cycles. The &quot;rM2M_CfgFlush&quot; function must be called so that the configuration memory block is saved
in a non-volatile manner in the FLASH.

Chapter 12 Device Logic (Pawn)
native rM2M_CfgWrite(cfg, pos, const data{}, size);
Saves the transferred data block at the specified position in a configuration memory block. Note that the
configuration memory block is either saved in the RAM in a volatile manner (Bit0 = RM2M_CFG_
VOLATILE) or in the FLASH in a non-volatile manner (Bit0 = 0, default) depending on the type of
storage selected via the &quot;rM2M_CfgInit&quot; function. The function is also passed which of the 10 available
memory blocks in the internal flash memory should be used. Use the &quot;rM2M_Pack&quot;, &quot;rM2M_
SetPacked&quot; or &quot;rM2M_SetPackedB&quot; functions to generate the data block that should be saved. The
time stamp is updated, so that the configuration memory block is automatically synchronised with the

Note: The energy consumption in continuous conversion mode is significantly higher than in single
conversion mode. The lowest level of energy consumption is only achieved once the PT100/1000
interface is closed via the &quot;Temp_Close&quot; function. This means that even if the PT100/1000 interface
was initialised in single conversion mode, it should be closed as soon as the measurement value is read
out.

native LoRa_Setbuf(LoRa, rxbuf{}, rxlen, txbuf{}, txlen);
Provides the firmware with one buffer for sending and one for receiving characters via the UART
interface, that is connected to the LoRa module, from the RAM area reserved for the device logic.
When this function is called, the system switches from the 128 byte buffers integrated in the firmware to
the transferred buffers.
Important note: If required, this function must be called before the UART interface is initialised
via the &quot;LoRa_Init()&quot; function.
Parameter

Explanation
Number of the UART interface that is connected to the LoRa module; for the
myDatalogEASY IoTmini always 0
rxbuf
Static byte array that should be used as a buffer to receive characters via the
UART interface
rxlen
Size of the receiving buffer in byte
Note: If the function is called up again and the size is set to &quot;0&quot; during the
process, then the system switches back to the integrated buffer (128 bytes). The
transferred static byte array can then be used by the script again.
txbuf

If an error occurs while executing the Device Logic, the corresponding error code is entered in the device log
and the Device Logic is restarted. If such an error occurs more than three times in 24 hours, the Device Logic
is deactivated and error handling is activated (see &quot;Error handling&quot; on page 32). The parameter for all log
entries except &quot;SCRIPT_ERR&quot; contains the 32-bit instruction pointer of the PAWN abstract machine (AMX).
Two entries are generated in the device log as only 16-bit values can be saved in the parameter of a log entry.
The first entry contains Bit31-Bit16 and the second entry contains Bit15-Bit0 of 32-bit instruction pointer.

12.5 Syntax
12.5.1 General syntax
12.5.1.1 Format
Identifiers, numbers and characters are separated by spaces, tabs, line breaks and &quot;form feed&quot;. A series of
one or more of these separators is recognised as an empty space.
12.5.1.2 Optional semicolons
Semicolons (used to finish a statement) are optional if they are at the end of a line. Semicolons are required to
separate several statements in a line. An expression can be split across several lines, though the postfix
operators must be on the same line as the operand.
12.5.1.3 Comments
Text between the /* and */ symbols (both symbols can be on the same or different lines) and text following //
(to the end of the line) are comments. Comments must not be nested. The compiler considers comments to
be blank space. A documentation comment is a comment that starts with &quot;/** &quot; (two stars and space after the
second star) and ends with &quot;*/&quot;. A comment that starts with &quot;/// &quot; (three forward slashes and a space after the
third slash) is also a documentation comment. The parser can support the documentation comment in
different ways, for example, by using it to generate online help.
12.5.1.4 Identifier
Names of variables, functions and constants. Identifier comprises the characters a...z, A...Z, 0...9, _ or @.
The first character must not be a number. The characters @ and _ on their own are not valid identifiers, e.g.
&quot;_Up&quot; is a valid identifier but &quot;_&quot; is not. Pawn distinguishes between upper and lower case. The parser cuts
identifiers off after a certain length. By default, only the first 16 characters are referenced for distinguishing
purposes.

&quot;12.0&quot; and &quot;0.75&quot; are valid floating-point numbers. An exponent can optionally be added. The notation is the
letter &quot;e&quot; (lower case) followed by an integer numerical constant. For example, &quot;3.12e4&quot; or &quot;12.3e-3&quot; are valid
floating-point numbers with an exponent.
12.5.2 Variables
12.5.2.1 Declaration
The keyword &quot;new&quot; declares a new variable. For special declarations, the keyword &quot;new&quot; is replaced with
&quot;static&quot; (see &quot;Static local declaration&quot; on page 166). The value of the new variable is zero, provided that is not
initialised explicitly.
A variable declaration can appear
At every position at which an expression is valid - local variable
l At every position at which a function declaration or the implementation of the function is valid - global
variables
l In the first expression of a &quot;for&quot; loop (see &quot;For (expression 1; expression 2; expression 3) statement &quot; on
page 176) - local variable
l
Example:
new a;
// without initialisation (value is 0)
new b = 3; // with initialisation (value is 3)
12.5.2.2 Local declaration
A local declaration appears within a statement block. A variable can only be accessed within this block and
the blocks that it comprises. A declaration within the first expression of a loop instruction is also a local
declaration.
12.5.2.3 Global declaration
A global declaration appears outside of a function and a global variable can be used in any function. Global
variables can only be initialised with constant expressions.
Rev. 01
165
12.5.2.4 Static local declaration
A local variable is destroyed if the execution leaves the block in which the variable was created. Local
variables in a function only exist during the operating time of the specified function. Each new call up of the
function creates and initialises new local variables. The variable will also remain in the memory at the end of
the function, if a local variable is declared with the keyword &quot;static&quot; instead of &quot;new&quot;. This means that static,
local variables provide permanent private storage that can only be accessed by a single function (or block).
Static local variables can only be initialised with constant expressions, the same way as global variables.
12.5.2.5 Static global declaration
A static global variable acts in the same way as a global variable with the difference that the variable is only
valid in the file in which it was declared. Replace the keyword &quot;new&quot; with &quot;static&quot; to declare a global variable
as static.
12.5.2.6 Floating point values
The pawn supports floating point values. These can be added at every point at which a variable declaration is
valid.
Example:
new Float:a;
// without initialisation (value is 0.0)
new Float:b = 3.0; // with initialisation (value is 3.0)
12.5.3 Constant variables
It is sometimes necessary to create a variable that is initialised once and is then not meant to be changed
again. Such a variable acts in a similar way to a symbolic constant although it is still a variable. To declare a
constant variable, place the keyword &quot;const&quot; between the keyword that starts the variable declaration (&quot;new&quot;,
&quot;static&quot;) and the name of the variables.
Example:
new const address[4] = { 192, 0, 168, 66 }
static const status /* initialised to zero */
Typical situations in which you could use a constant variable, include:
l
l
To create an &quot;array&quot; constant. Symbolic constants cannot be accessed via the index.
It is a special case when array arguments are marked as &quot;const&quot; in a function. Arrays arguments are
always transferred via a reference. If the arguments are declared to be &quot;const&quot;, they are protected
against unwanted changes. See examples of &quot;const function arguments&quot; in the chapter &quot;Function
arguments (&quot;call-by-value&quot; versus &quot;call-by-reference&quot;)&quot; on page 179.
12.5.4 Array variables
12.5.4.1 One-dimensional arrays
The name[constant] syntax declares the name as an array of &quot;constant&quot; elements, where each element is an
entry. &quot;name&quot; is a placeholder for the name of the variable and &quot;constant&quot; is a positive value not equal to zero.
&quot;constant&quot; is optional and can be omitted. If there is no value between the brackets, the number of elements is
equal to the number of initial values. The array index area is &quot;zero-based&quot;, which means that the first element
is &quot;name[0]&quot; and the last element is &quot;name[constant-1]&quot;.
166
Rev. 01
Chapter 12 Device Logic (Pawn)
12.5.4.2 Initialisation
Data objects can be initialised during their declaration. The initialised value from global data objects must be a
constant value. Global or local arrays must also be initialised with constant values. Data that is not initialised
are zero by default.
Example:
List: valid declaration
new i = 1
new j
new k = ’a’
new a[] = [1,4,9,16,25]
new s1[20] = [’a’,’b’]
new s2[] = ’’Hello world...’’
/* j is 0 */
/* k has the character code of ’a’ */
/* a has 5 elements */
/* the remaining 18 elements are 0 */
/* an unpacked string */
List: invalid declaration
new c[3] = 4
new i = &quot;Good-bye&quot;
new q[]
new p[2] = { i + j, k - 3 }
/* An array cannot be set to an individual
value */
/* only an array can hold a string */
/* Unknown size for an array */
/* Array initialisers must be constants */
12.5.4.3 Progressive initialisation for arrays
The point operator continues the initialisation of the arrays based on the last two initialised values. The point
operator (three points, &quot;...&quot;) initialises the array up to the array limit.
Example: List: array initialisers
new a[10] = { 1, ... }
new b[10] = { 1, 2, ... }
new c[8] = { 1, 2, 40, 50, ... }
new d[10] = { 10, 9, ... }
// sets all of the elements to 1
// b = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
// c = 1, 2, 40, 50, 60, 70, 80, 90
// d = 10, 9, 8, 7, 6, 5, 4, 3, 2, 1
12.5.4.4 Multi-dimensional arrays
(Only arrays with up to three dimensions are supported)
Multi-dimensional arrays are arrays that include references to other sub-arrays. For example, a twodimensional array is an &quot;array on one-dimensional arrays&quot;.
Example for the declaration of two-dimensional arrays:
new a[4][3]
new b[3][2] = [ [ 1, 2 ], [ 3, 4 ], [ 5, 6 ] ]
new c[3][3] = [ [ 1 ], [ 2, ...], [ 3, 4, ... ] ]
new d[2]{10} = [ &quot;agreement&quot;, &quot;dispute&quot; ]
new e[2][] = [ ’’OK’’, ’’Cancel’’ ]
new f[][] = [ ’’OK’’, ’’Cancel’’ ]
Rev. 01
167
As the last two declarations (variables &quot;e&quot; and &quot;f&quot;) illustrates, the last dimension has an unspecified length. In
this case, the length of the sub-array is detected by the associated initialiser. Each sub-array is a different
length. In this specific example, &quot;e[1][5]&quot; includes the letter &quot;l&quot; of the word &quot;Cancel&quot;. However, &quot;e[0][5]&quot; is
invalid as the sub-array e[0] only comprises three entries (the letters &quot;O&quot;, &quot;K&quot; and the zero terminator). The
difference between the declarations of the &quot;e&quot; and &quot;f&quot; arrays is that we enable the compiler to determine the
number of higher dimensions for &quot;f&quot;. &quot;sizeof f&quot; and &quot;sizeof e&quot; are both 2 (see &quot;Arrays and the &quot;sizeof&quot; operator&quot;
on page 168).
12.5.4.5 Arrays and the &quot;sizeof&quot; operator
The &quot;sizeof&quot; operator returns the number of elements of a variable. The &quot;sizeof&quot; result of a simple (non array)
variable is always 1.
An array with one dimension comprises a number of elements and the &quot;sizeof&quot; operator returns this quantity.
The code section below would therefore issue &quot;5&quot;, as the array comprises four characters and the zero
terminator.
new msg[] = ’’Help’’
printf(’’%d’’, sizeof msg);
The &quot;sizeof&quot; operator always returns the number of entries even for a &quot;packed&quot; array. The code section below
also issues &quot;5&quot;, as the variable comprises five entries even though it requires less memory space.
new msg{} = &quot;Help&quot;
printf(’’%d’’, sizeof msg);
For multi-dimensional arrays, the &quot;sizeof&quot; operator can return the number of elements for every dimension.
An element in the last (lowest) dimension is a single entry, while it is a sub-array in the highest dimension.
Please note that in the following code section, the &quot;sizeof matrix&quot; syntax returns the number of elements of the
higher dimension and that the &quot;sizeof matrix[]&quot; syntax issues the lower dimension of the two-dimensional
array. The code section issues three (higher dimension) and two (lower dimension).
new matrix[3][2] = { { 1, 2 }, { 3, 4 }, { 5, 6 } }
printf(’’%d %d’’, sizeof matrix, sizeof matrix[]);
The application of the &quot;sizeof&quot; operator on multi-dimensional arrays is particularly practical when it is used as
a standard value for function arguments.

12.5.5 Operators and expressions
12.5.5.1 Notational conventions
The use of some operators is dependent on the relevant type of operand. The following notations are
therefore used in this chapter:
e
Any expression
v
Any expression that can be assigned a value (&quot;lvalue&quot; expression - variable)
a
An array
f
A function
s
A symbol - this can be a variable, a constant or a function
12.5.5.2 Expressions
An expression consists of one or several operands with an operator. The operand can be a variable, a
constant or another expression. An expression followed by a semicolon is a statement.
Examples of expressions:
v++ f(a1, a2)
v = (ia1 * ia2) / ia3
12.5.5.3 Arithmetic
Operator Example
+
e1 + e2 Result of adding e1 and e2
-
Explanation
e1 - e2
Result of subtracting e2 from e1
-e
Result of the arithmetic negation of e (two's complement)
*
e1 * e2
Result of multiplying e1 with e2
/
e1 / e2
Result of dividing e1 by e2. The result is truncated to the closest whole number that is
less or equal to the quotient. Positive and negative values are rounded down (negative
infinity).
%
e1 % e2
Result is the remainder of the division of e1 by e2. The prefix is the same as that of e2
++
v++
Increases v by 1. The result of the expression is the value before the increase.
++v
Increases v by 1. The result of the expression is the value following the increase.
v--
Decreases v by 1. The result of the expression is the value before the decrease.
--v
Decreases v by 1. The result of the expression is the value following the decrease.
--
Note: The unary + is not defined in the pawn. The operators ++ and -- change the operand. The
operand must be a &quot;lvalue&quot;.
Rev. 01
169
12.5.5.4 Bit manipulation
Operator Example
Explanation
~
~e
The result is the one's complement of e.
&gt;&gt;
e1 &gt;&gt; e2 The result of the arithmetic shift to the right of e1 by e2 bits. The shift is signed: The bit
on the far left is copied to the free bits of the result.
&gt;&gt;&gt;
e1 &gt;&gt;&gt;
e2
&lt;&lt;
e1 &lt;&lt; e2 Result: Shift to the left of e1 by e2 bits. The free bits of the result are filled with 0. There
is no difference between an arithmetic and a logical shift to the left.
&amp;
e1 &amp; e2

|
e1 | e2
The result is the bitwise logical &quot;or&quot; of e1 and e2.
^
e1 ^ e2
The result is the bitwise logical &quot;exclusive or&quot; of e1 and e2.
The result of the logical shift to the right of e1 by e2 bits. The shift is unsigned. The free
bits of the result are filled with 0.
12.5.5.5 Assignment
The result of an assignment expression is the value of the operand following the assignment.
Operator Example
Explanation
=
v=e
Assigns the value of e to the variable v
v=a
Assigns the array a to variable v. v must be an array of the same size and with the
same dimensions as a. a can be a character string or an array.
Note: The following operators combine an assignment with an arithmetic or bitwise operation. The
result of the expression is the value of the left operand following the arithmetic or bitwise operation.
Operator Example
+=
v += e
Increases v by e
Explanation
-=
v -= e
Decreases v by e
*=
v *= e
Multiplies v with e

12.5.5.6 Comparative operators
A logical &quot;false&quot; is represented by an integer value of 0; a logical &quot;true&quot; is represented by a value that is not 0.
Results of a comparative expression are either 0 or 1 and the &quot;tag&quot; is set to &quot;bool&quot;.
Operator Example
Explanation
==
e1 == e2 The result is &quot;true&quot; if e1 and e2 are the same.
!=
e1 != e2
The result is &quot;true&quot; if e1 and e2 are not the same.
Note: The following operators can be linked, the same as in the expression &quot;e1 &lt;= e2 &lt;= e3&quot;. This
means that the result is &quot;1&quot; if every single comparison is true and &quot;0&quot; if at least one comparison is false.
Operator Example
Explanation
&lt;
e1 &lt; e2 The result is a logical &quot;true&quot; if e1 is less than e2.
&lt;=
e1 &lt;= e2 The result is a logical &quot;true&quot; if e1 is less or equal to e2.
&gt;
e1 &gt; e2
&gt;=
e1 &gt;= e2 The result is a logical &quot;true&quot; if e1 is greater or equal to e2.
The result is a logical &quot;true&quot; if e1 is greater than e2.
12.5.5.7 Boolean
A logical &quot;false&quot; is represented by an integer value of 0; a logical &quot;true&quot; is represented by a value that is not 0.
Results of a comparative expression are either 0 or 1 and the &quot;tag&quot; is set to &quot;bool&quot;.
Operator Example
Explanation
!
!e
The result is a logical &quot;true&quot;, if e is logical &quot;false&quot;.
||
e1 || e2
&amp;&amp;
e1 &amp;&amp; e2 The result is &quot;true&quot; if e1 and e2 are logical &quot;true&quot;. The expression e2 is only evaluated if
e1 is logical &quot;true&quot;.
Rev. 01
The result is &quot;true&quot;, if either e1 or e2 (or both) are logical &quot;true&quot;. The expression e2 is
only evaluated if e1 is logical &quot;false&quot;.
171
12.5.5.8 Other
Operator
Example
[]
a[e]
Explanation
Array index: The result is the entry at position e of array a.
{}
a{e}
Array index: The result is the index at position e of &quot;packed&quot; array a:
()
f(e1, e2, ... eN)
The result is the value that is returned by function f. The function is called up
with parameters e1, e2, ... eN. The sequence of the evaluation of the
parameters is not defined. (The implementation of the script engine may
evaluate the parameters in reverse order.)
?:
e1 ? e2 : e3
The result is either e2 or e3, depending on the value of e1. The conditional
expression is a composite expression with a two-part operator, &quot;?&quot; and &quot;:&quot;.
The expression e2 is evaluated if e1 is logical &quot;true&quot;; e3 is evaluated if e1 is
logical &quot;false&quot;.
:
tagname: e
&quot;Tag&quot; overwritten: The value of the expression does not change, although
the &quot;tag&quot; does change.
defined
defined s
Result is &quot;1&quot; if the symbol was defined. The symbol can be a constant or a
global or local variable. The &quot;tag&quot; of the expression is &quot;bool&quot;
sizeof
sizeof s
The result is the number of elements of the specified variable. An element
is an entry for simple variables and for one dimensional arrays. For multidimensional arrays, the result is the number of elements (sub-arrays) in the
highest dimension. Add [] to the name of the array to specify a lower
dimension. The result is 0 if the size of the variable is not known. If this
operator is used in a &quot;default&quot; value of a function, the expression is
executed at the time that the function was called up and not at the time that
the definition was completed.
tagof
tagof s
The result is a unique number that represents the &quot;tag&quot; of the variables, the
constants, the return value of a function or the name of the &quot;tag&quot; title. If this
operator is used in a &quot;default&quot; value of a function, the expression is
executed at the time that the function was called up and not at the time that
the definition was completed.
12.5.5.9 Priority of the operators
The following table groups the operators with the same priority, starting with the highest priority at the top of
the table.
If the evaluation of an expression is not explicitly justified with brackets, it is categorised by the association
rules. For example: a*b/c is equal to (a*b)/c based on the left to right association, and a=b=c is equal to
a=(b=c).

12.5.6 Statements
A statement can comprise one or several lines. A line can comprises two or more statements.
Statements for the sequence control (if, if-else, for, while, do-while and switch) can be nested.
12.5.6.1 Statement label
A label consists of an identifier followed by a &quot;:&quot;. A label is a &quot;Jump target&quot; of a &quot;goto&quot; statement.
Rev. 01
173
Each statement can be marked with a label. The label must be followed by a statement, which can also be an
&quot;empty statement&quot;.
The scope of a label is the function in which it was declared, i.e. a &quot;goto&quot; statement cannot jump from the
current function to another function.
12.5.6.2 Composite statements
A composite statement (also known as a block) is a series of zero or several statements that is enclosed by
brackets (&quot;{&quot; and &quot;}&quot;). The closing bracket (&quot;}&quot;) must not be followed by a semicolon. Each statement can be
replaced by a block. A composite statement that does not comprise any statements is a special case and is
known as an &quot;empty statement&quot;.
12.5.6.3 Expression statement
Each expression becomes a statement when a semicolon (&quot;;&quot;) is added. An expression also becomes a
statement, if the expression is only followed by blank spaces to the end of the line, and the expression is not
continued in the next line.
12.5.6.4 Empty statement
An empty statement does not execute any statements and consists of a block statement without statements,
i.e. it consists of the &quot;{ }&quot; symbol. Empty statements are implemented in control flow statements without
actions (e.g. &quot;while (!iskey()) {}&quot;) or if a label is defined exactly before the closing bracket of a block statement.
An empty statement does not end with a semicolon.
12.5.6.5 Assert expression
The program is aborted with a runtime error if the expression is logical &quot;false&quot;
Note: This expression protects against &quot;impossible&quot; or invalid conditions. In the following example, a
negative fibonacci number is invalid. The assert statement marks this error as a programming error.
Assert statements should only ever highlight programmer errors and never user inputs.
Example:
fibonacci(n)
{
assert n &gt; 0
new a = 0, b = 1
for (new i = 2; i &lt; n; i++)
{
new c = a + b
a = b
b = c
}
return a + b
}
174
Rev. 01
Chapter 12 Device Logic (Pawn)
12.5.6.6 Break
Terminates and leaves the smallest, encircling &quot;do&quot;, &quot;for&quot; or &quot;while&quot; statement at any point in the loop. The
&quot;break&quot; statement moves the program flow to the next statement outside the loop.
Example:
example(n)
{
new a = 0
for(new i = 0; i &lt; n ; i++ )
{
a += i
if(i&gt;10)
break
a += 1
}
return a
}
12.5.6.7 Continue
Terminates the current iteration of the smallest encircling &quot;do&quot;, &quot;for&quot; or &quot;while&quot; statement and moves the
program control to the conditional part of the loop.
Example
example(n)
{
new a = 0
for(new i = 0; i &lt; n ; i++ )
{
a += i
if(i&gt;10)
continue
a += 1
}
return a
}
Rev. 01
175
12.5.6.8 Do statement while (expression)
Executes a statement before the conditional part (the &quot;while&quot; condition) is evaluated. The statement is
repeated as long as the condition is logical &quot;true&quot;. The statement is executed at least once.
Example:
example(n)
{
new a = 0
do
{
a++
}
while(n &gt;= 0)
return a
}
12.5.6.9 Exit expression
Cancels the program. The expression is optional, however, if present it must start and end on the same line
as the &quot;exit&quot; statement. The exit statement returns the expression value or zero to the main application, if no
expression is specified.
12.5.6.10 For (expression 1; expression 2; expression 3) statement
All three of the expressions are optional.
Expression 1:
Is only evaluated once before entering the loop. This expression can be used to initiate a variable. This
expression also includes the variable declaration by means of the &quot;new&quot; syntax. A variable that is
declared at this stage is only valid in the loop. It is not possible to combine an expression (with existing
variables) and a declaration of new variables in this field. All of the variables must either already exist in
this field, or they must all be declared in this area.
Expression 2:
This expression is executed before every run of the loop and terminates the loop if the expression
logical &quot;false&quot; is returned. If this expression is omitted, it is assumed that the result of expression 2 is
logical &quot;true&quot;.
Expression 3:
This expression is executed each time the statement is completed. The program control moves from
expression 3 to expression 2 for the next (conditional) iteration of the loop.
176
Rev. 01
Chapter 12 Device Logic (Pawn)
Example:
example(n)
{
new a = 0
for(new i = 0; i &lt; n; i++)
{
a++
}
return a
}
The &quot;for ( ; ; )&quot; statement is the same as the &quot;while (true)&quot; statement.
12.5.6.11 Goto label
Moves the program control (unconditionally) to the statement that follows the specified label. The label must
be within the same function as the &quot;goto&quot;-statement (a &quot;goto&quot;-statement cannot jump out of a function).
12.5.6.12 If (expression) statement 1 else statement 2
Executes statement 1 if the results of the expression is logical &quot;true&quot;. The &quot;else&quot;clause of the &quot;if&quot; statement is
optional. If the result of the expression is logical &quot;false&quot; and there is an &quot;else&quot; clause, the statement that is
associated with the &quot;else&quot; clause (statement 2) is executed.
Example:
example(n)
{
if(n &lt; 0)
return -1
else if (n == 0)
return 0
else
return 1
}
12.5.6.13 Return expression
Terminates the current function and moves the program control to the next statement following the function
call. The expression value is returned as the function result. The expression can be an array or a character
string. The expression is optional, however, if present it must start on the same line as the &quot;return&quot; statement.
Zero is returned if no expression is specified.
12.5.6.14 switch (expression) {case list}
Transfers the sequence control to the various statements within the &quot;switch&quot;, depending on the value of the
&quot;switch&quot; expression. The main part of the &quot;switch&quot; statement is a composite statement that comprises a series
of &quot;case&quot; clauses. Each &quot;case&quot; clause starts with the keyword &quot;case&quot; followed by a list of constants and a
statement. The list of constants is a series of expressions separated by commas, each of which is evaluated
as a constant value. This list ends with a colon. To specify an area in this list, separate the lower and upper
limit of the area with a double point (&quot;..&quot;). An example for an area is: &quot;case 1..9:&quot;.
Rev. 01
177
The &quot;switch&quot; statement shifts the sequence control to a &quot;case&quot; clause if a value from the list corresponds to the
value of the &quot;switch&quot; expression.
The &quot;default&quot; clause consists of the &quot;default&quot; keyword and a double point. The &quot;default&quot; clause is optional,
however, if it is specified it must be included as the last entry in the &quot;case&quot; list. The &quot;switch&quot; statement shifts
the sequence control to the &quot;default&quot; clause if none of the &quot;case&quot; clauses comply with the &quot;switch&quot; expression.
Example:
example(n)
{
new a = 0
switch (n)
{
case 0..3:
a = 0
case 4,6,8,10:
a = 1
case 5,7:
a = 2
case 9:
a = 3
default:
a = -1
}
return a
}
12.5.6.15 While (expression) statement
Evaluates the expression and executes the statement if the result of the expression is logical &quot;true&quot;. The
program control returns to the expression again once the statement has been executed. The statement is
therefore executed as long as the expression is logical &quot;true&quot;.
Example:
example(n)
{
new a = 0
while(n &gt;= 0)
{
a++
}
return a
}

12.5.7 Functions
A function declaration specifies the name of the function and the formal parameters enclosed in brackets. A
function can also return a value. A function must be defined globally, i.e. declared outside of another function
and is globally available.
If the function declaration is followed by a semicolon (instead of a statement), this is a forward declaration of a
function.
The &quot;return&quot; statement sets the return value of the function. For example, the return value of the &quot;sum&quot;
function (see below) is the sum of both parameters. The &quot;return&quot; expression is optional.
sum(a, b)
{
return a + b
}
The arguments of a function are (declared implicitly) local variables for this function. The function call specifies
the values of the arguments. Another example of a complete definition of a function is &quot;leap year&quot; that
indicates &quot;true&quot; or &quot;false&quot; for the relevant year.
leapyear(y)
{
return y % 4 == 0 &amp;&amp; y % 100 != 0 || y % 400 == 0
}
Details of the statements used in this example are provided in the chapter &quot;Operators and expressions&quot; on
page 169.
Generally, functions include local variable declarations and consist of a block statement.
Note: In the next example, the &quot;assert&quot; statement prevents negative values for the exponent.
power(x, y)
{
/* returns xy */
assert y &gt;= 0
new r = 1
for (new i = 0; i &lt; y; i++)
r *= x
return r
}
A function can comprise several &quot;return&quot; statements, for example, one is used to quickly terminate a function if
invalid parameters are transferred, or when it becomes apparent that the function has nothing to do. If a
function returns an array, all of the &quot;return&quot; statements must return an array with the same number of entries.
12.5.7.1 Function arguments (&quot;call-by-value&quot; versus &quot;call-by-reference&quot;)
The &quot;faulty&quot; function in the next example has a parameter that is used in the loop to calculate the factorial of
this number. It must be noted that the function modifies the argument.
Rev. 01
179
main()
{
new v = 5
new f = faculty(v)
}
faculty(n)
{
assert n &gt;= 0
new result = 1
while (n &gt; 0)
result *= n-return result
}
Regardless of what (positive) value the &quot;n&quot; variable has at the start of the &quot;while&quot; loop, &quot;n&quot; will equal zero at
the end of the function. In the &quot;faculty&quot; function, for example, the parameter is transferred as a value (&quot;by
value&quot;), which means that changes to the &quot;n&quot; variable are only valid locally in the &quot;faculty&quot; function. In other
words, the &quot;v&quot; variable in the &quot;main()&quot; function has the same value before and after the function is called up.
Arguments can be transferred as a value (&quot;by value&quot;) or as a reference (&quot;by reference&quot;). A function argument
that is to be transferred as a reference must have the &quot;&amp;&quot; prefix preceding the name. The arguments are
transferred to the function as a value by default.
Example:
swap(&amp;a, &amp;b)
{
new temp = b
b = a
a = temp
}
To transfer an array to a function, add a pair of brackets (&quot;[]&quot;) to the name of the argument. The number of
entries can also be specified. This improves the error detection of the compiler's parser.
Example:
addvector(a[], const b[], size)
{
for (new i = 0; i &lt; size; i++)
a[i] += b[i]
}
Arrays are always transferred as a reference.
Note: The &quot;b&quot; array in the above-mentioned example is not changed in the function. This function
argument was declared as a &quot;const&quot; to make this explicit. In addition to the improved error detection, it
also enables the compiler to generate a more efficient code.
180
Rev. 01
Chapter 12 Device Logic (Pawn)
The following code example calls up the &quot;addvector&quot; function and adds five to each element of the &quot;vect&quot;
variables:
new vect[3] = [ 1, 2, 3 ]
addvector(vect, [5, 5, 5], 3)
/* vect[] now comprises the values 6, 7 and 8 */
12.5.7.2 Named parameters versus fixed parameters
In the previous examples, the order of the parameters in a function call were important as each parameter
was copied to the same position of the function parameter. For example, in the &quot;weekday&quot; function (defined
below), the expression &quot;weekday(12 ,31, 1999)&quot; would be used to get the weekday of the last day of the last
century.
weekday(month, day, year)
{
/* returns the day of the week: 0=Saturday, 1=Sunday, etc. */
if (month &lt;= 2)
month += 12, --year
new j = year % 100
new e = year / 100
return (day + (month+1)*26/10 + j + j/4 + e/4 - 2*e) % 7
}
The date format changes depending on the culture and country, while the USA use the month/day/year
format, European countries frequently use the day/month/year format and technical publications use the
year/month/day (ISO/IEC 8824) format. In other words, the sequence of the parameters is not &quot;standardised&quot;
or &quot;normal&quot;. For this reason, there is an alternative way of transferring parameters to a function, by using
&quot;named parameters&quot;. These are illustrated in the next example (the function was declared in the same way as
the previous example).
new wkday1 = weekday( .month = 12, .day = 31, .year = 1999)
new wkday2 = weekday( .day = 31, .month = 12, .year = 1999)
new wkday3 = weekday( .year = 1999, .month = 12, .day = 31)
In &quot;named parameters&quot;, a dot (&quot;.&quot;) precedes the name of the argument. The argument of the function can be
set to any expression that is valid for the argument. In the event of a named parameter, the equals sign (&quot;=&quot;)
does not refer to an allocation but instead links the expression with a function argument.
Fixed and named parameters can be mixed together, although the fixed parameters must be specified before
the named parameters.
12.5.7.3 Standard values of function arguments
A function argument can have a standard value. The standard value of a function argument must be a
constant. To specify a standard value, add an equals sign (&quot;=&quot;) and the value to the name of the parameter.
The standard value is adopted if a placeholder is specified instead of a valid function parameter during a
function call. The placeholder is the underscore character (&quot;_&quot;). The argument placeholder is only valid for
parameters with a standard value.
The right argument placeholders can be removed from the list of arguments.
Rev. 01
181
For example, if the &quot;increment&quot; function is defined as follows:
increment(&amp;value, incr=1)
{
value += incr
}
The following function calls are all the same:
increment(a)
increment(a, _)
increment(a, 1)
Standard values for arguments that are transferred as a reference are helpful in making these parameters
optional. For example, if the &quot;divmod&quot; function was written to return the quotient and the rest as a parameter.
divmod(a, b, &amp;quotient=0, &amp;remainder=0)
{
quotient = a / b
remainder = a % b
}
Based on the previous definition of the &quot;divmod&quot; function, the following function calls are all valid:
new p, q
divmod(10, 3, p, q)
divmod(10, 3, p, _)
divmod(10, 3, _, q)
divmod(10, 3, p)
divmod 10, 3, p, q
The next example adds the value of an array to another one. The values of the array are increased by one if
only one parameter is specified:
addvector(a[], const b[] = {1, 1, 1}, size = 3)
{
for (new i = 0; i &lt; size; i++)
a[i] += b[i]
}
12.6 Differences to C
l
l
182
The pawn is missing the input mechanism of C and is an &quot;integer-only&quot; variant of C. There are no
structures or unions. Floating point support must be implemented with user-defined operators and the
help of native functions.
The syntax for floating point values is stricter than that in C. Values such as &quot;.5&quot; and &quot;6.&quot; are acceptable
in C but must be written as &quot;0.5&quot; and &quot;6.0&quot; in the pawn. The decimal point is optional in C. If an
exponent is included, then you can write &quot;2E8&quot; in C, however the pawn will not accept the capital letter
&quot;E&quot;. Use the lower case letter &quot;e&quot;. It requires a comma: e.g. &quot;2.0e8&quot; (see &quot;Numerical constants&quot; on
page 165).

The pawn does not support any &quot;pointer&quot;. The pawn includes a &quot;reference&quot; argument to transfer
function parameters as a reference (see &quot;Function arguments (&quot;call-by-value&quot; versus &quot;call-byreference&quot;)&quot; on page 179). The &quot;placeholder&quot; argument replaces some applications of the ZERO
pointer (see &quot;Standard values of function arguments&quot; on page 181).
Numbers can be specified in a hexadecimal, decimal or binary format. The octal format is not
supported (see &quot;Numerical constants&quot; on page 165). Hexadecimal numbers must start with &quot;0x&quot; (&quot;x&quot; in
lower case). The prefix &quot;0X&quot; is invalid.
&quot;Cases&quot; in a &quot;switch&quot;-statement are not &quot;fall through&quot;. At least one statement must follow the &quot;case&quot;
label. You must create a composite statement (with {}) to execute several statements (see &quot;switch
(expression) {case list}&quot; on page 177). The &quot;switch&quot; statement is a &quot;conditional goto&quot; in C/C++. The
&quot;switch&quot; statement is a structured &quot;if&quot; in the pawn.
A &quot;break&quot; statement only terminates loops. In C/C++, the &quot;break&quot; statement also terminates a &quot;case&quot; in
a &quot;switch&quot; statement.
The pawn supports &quot;array assignments&quot; with the limitation that both of the arrays must be the same
length. For example, if &quot;a&quot; and &quot;b&quot; arrays have six lines, the expression &quot;a=b&quot; is valid. In addition to
character strings, the pawn also supports literal arrays and thus expressions such as &quot;a = {0,1,2,3,4,5}&quot;
where &quot;a&quot; is an array variable with six elements.
&quot;defined&quot; is an operator and not a preprocessor directive. The &quot;defined&quot; operator in the pawn works
with constants (declared with &quot;const&quot;), global variables, local variables and functions.
The &quot;sizeof&quot; operator returns the size of the variables in &quot;elements&quot; and not in &quot;bytes&quot;. An element is an
entry or sub-array. Further details are provided in the chapter &quot;Other&quot; on page 172.
An empty statement is an empty block (with {}) and not a semicolon (see &quot;Composite statements&quot; on
page 174). This change prevents frequent errors.
A division is completed in such a way that the remainder of the division has (or ought to have) the same
prefix as the denominator. Divisions (operator &quot;/&quot;) are always rounded down to the smaller whole
number (whereby -2 is smaller than -1). For example, 5/2 = 2 (2.5 is rounded down to 2), -5/2 = -3 (-2.5
is rounded down to -3). The &quot;%&quot; operator always generates a positive result regardless of the prefix of
the numerator (see &quot;Operators and expressions&quot; on page 169).
There is no unary &quot;+&quot; operator as it is a &quot;no-operation&quot; operator anyway (&quot;a = +1&quot; is not valid; correct: &quot;a
= 1&quot;).
Three bit by bit operators have different priorities than in C. The priority level of the &quot;&amp;&quot;, &quot;^&quot; and &quot;|&quot;
operator is higher than the relational operators. Dennis Ritchie explains that these operators were
assigned a low priority level in C as early C compilers did not yet include the logical &quot;&amp;&amp;&quot; and &quot;| |&quot;
operators so that bit by bit &quot;&amp;&quot; and &quot;|&quot; were used instead.
The keyword &quot;const&quot; in the pawn implements the &quot;enum&quot; functionality of C.

In most cases, the forward declarations of functions (i.e. prototypes) are not necessary. A pawn is a
two-pass compiler. It detects all of the functions during the first cycle and uses them during the second.
User-defined operators must however be declared before use. If available, forward declarations must
be exactly the same as the definition of the function. The parameter names in the prototypes and the
definitions of the functions must be identical. The pawn attends to the parameter name in the prototype
due to the &quot;named parameter&quot; function. The pawn uses prototypes to call up the forward declared
functions. To use these with the named parameters during this process, the compiler must already
know the names of the parameters (and their position in the parameter list). The parameter names in
the prototypes must therefore match those in the definitions.
Rev. 01
Chapter 13 Data Descriptor
The basic principle of the myDatalogEASY IoTmini is &quot;storage-2-storage&quot; data transmission. For this type of
data transmission, neither the myDatalogEASY IoTmini nor the server must know about the logical content of
the data blocks. Therefore, the only aim is to transport a block of data from A to B.
The data transferred from the myDatalogEASY IoTmini to the sever can therefore be selected freely. There
are1024 Byte available per data record that can be used as required. There are also another 10 independent
memory blocks each with 4000 Byte for the configuration data that can be used as required.
The content of the data block or configuration block must be described on the server so that the data and
configurations received from the myDatalogEASY IoTmini can also be used within the myDatanet interface
(reports, visualisations, graphics, etc.). The Data Descriptor contains the tool for describing the data as well
as the correct provision of the data for use within the interface.

15.2.1 Charging the power supply unit
All power supply units with an integrated and rechargeable energy store are delivered with a maximum
charge of 30% in accordance with applicable transport regulations. If you use an external charging voltage
(V IN) during operation, the power supply unit is constantly charged by the charge controller integrated in the
myDatalogEASY IoTmini .
If no external charging voltage (V IN) is available during operation, the power supply unit must be fully
charged before initial use.
For instructions on removing the rechargeable battery, see &quot;Replacing the power supply unit&quot; on page 189.
Important note: Only use the PSU Charger (300697) to charge the power supply units. The
charger specifications must be observed. The use of other chargers can destroy the power supply
unit, for example, causing the cells to leak or an explosion, etc.

The charging process starts as soon as the power supply unit is inserted in the charger. If the status LED on
the charger flashes red once every 5 seconds, the power supply unit inserted in the charger does not contain
a rechargeable energy store. If the status LED flashes red three times every 5 seconds, the supply voltage of
the charger is too low. In this case, check the cable connection between the plug-in power supply and the
PSU Charger and check whether the plug-in power supply is correctly connected to an electric socket. If the
status LED flashes green, a normal charging process is in progress. The charging process is complete when
the status LED turns green.

Chapter 15 Maintenance
If the status LED flashes red twice every 5 seconds, the power supply unit is faulty. Possible reasons for this
include a broken cable, short circuit or defective cells. In this case, the used power supply unit must be
replaced with a new one.
Note: Rechargeable batteries are wear parts that lose capacity over time. The capacity is also reduced at high
or low ambient temperatures and under intensive use.
Note: Ensure that power supply units, especially ones with integrated energy store (rechargeable
battery or battery), are disposed of in line with environmental requirements. Power supply units with
depleted rechargeable battery or battery can be returned to the manufacturer or handed in at suitable
collection points.
15.3 Power supply units with integrated energy store
While power supply units with integrated batteries (e.g. PSU713 BP ) are intended for single use and must be
disposed of accordingly after depletion, power supply units with integrated rechargeable batteries (e.g.
PSU413D+ AP ) can be recharged and used again and again. However, the service life of rechargeable
batteries is not indefinite. In addition to regular servicing and maintenance, its service life is also dependent on
the frequency of use and the operating and storage conditions.

17.3 Evaluating the device log
17.3.1 Evaluating the device log on the myDatanet server
The last 300 log entries on the myDatanet server can be called up via the button shown below that is located
in the measurement device list. As the log entries are sent to the server in the transmission cycle in the same
way as the measurement data, only the log entries up to the last server connection are available.
The manual for the server (&quot;myDatanet Server Manual &quot; 805002) includes a detailed description of the
evaluation of the device log on the myDatanet server.
17.3.2 Evaluating the device log using DeviceConfig
The DeviceConfig program can be used to read all of the stored log entries, including those that have not yet
been transferred to the myDatanet server, directly from the myDatalogEASY IoTmini via the USB interface.
A more detailed description about the evaluation of the device log using DeviceConfig is included in the user
manual for the DeviceConfig (&quot;myDatanetDeviceConfig Manual &quot; 805004).

NaN value
The myDatanet uses special encoding to display different error statuses in the measurement values,
for example. By setting a measurement value to &quot;NaN&quot;, it is clearly marked as invalid and is thus not
used for any further calculations. In the measurement value graphs, a measurement value that has
been set to &quot;NaN&quot; is indicated by an interruption in the graph. When downloading the data, a
measurement value set to &quot;NaN&quot; is indicated by an empty data field.
