This is an unofficial library for use with the dweet.io and dweetpro.io service. It’s developed to use with the main features as sending and receiving dweets. The library supports a secure connection between the service and the PLC controller. TLS encrypts all traffic. The dweet service also offers the opportunity to protect your “Thing” with a secret key.
Without purchasing a license (just download), the Dweet Library SL runs for 30 minutes without functional limitations and disconnects automatically (demo).

License Agreement
for the usage of a CODESYS Software or
CODESYS Software Package
General Terms of
License (End User License Agreement) for the supplied Software. Please read
this Software User Agreement carefully before using the supplied Software.
Downloading or installation of the Software constitutes recognition by the
customer of the conditions of this Agreement.
The following
conditions are agreed between you as the software user and the company 3S-Smart
Software Solutions GmbH (hereinafter referred to as 3S), 87439 Kempten
(Germany) and are legally binding.
With this
license agreement, you acquire the permission of use for Software from 3S (e.
g. http://codesys.com, http://store.codesys.com). Some products may only be
used for a limited period of time (Products with the name affix “Abo”,
“Abonnement” or “Subscription”). If you do not agree to the following license
agreement, then you, the user, are not permitted to save and/or install the
Software. Should you have already installed the Software, and you do not agree
to the license agreement, then immediately delete or uninstall the Software.
§ 1 Object of the License
Agreement
The object of
the License Agreement is the supplied Software that you have received either
directly or from the CODESYS Store. With the provided Software, the user is in
the position to use and/or to extend the CODESYS Development System and/or
implement a CODESYS runtime environment on a specific programmable logic
controller (PLC), herein termed "device". The user has the right to
install the functions of the Software after installation of the device software
and/or the CODESYS Development System.
In this way, the
user can use the functions as specified in the data sheet of the Software.
§ 2 Geographic Restriction
None
§ 3 Rights of Use
Different
license models grant different usage rights. A CODESYS Softcontainer or CODESYS
Key (hardware dongle) is required to use the demo, full or time license.
Free: Software
that is indicated as "Free" in the CODESYS Store is not subject to an
automatic license check by the manufacturer and can be used free of charge.
Demo: The user
can order a simple and non-transferable demo license to the supplied Software,
depending on availability. The license protected demo software is free of
charge but limited by time and/or functionality.
Full: The
provided Software is protected by license and requires a fee. The user acquires
an unrestricted, simple, and non-transferable license to use the supplied
Software with no restrictions.
Time license: Alternatively,
a time-limited license is offered to the user, with which the user acquires a
simple, non-transferable license to use the delivered software for an agreed,
contiguous period.
It is not
permitted to edit, modify, disassemble or decompile the Software or to use
other processes of reverse engineering to by-pass the licensing mechanism, or
to have these processes performed by third parties, insofar as this is not
absolutely required for exploiting the rights that result from licenses in all
events for open source components.
The Software can
be components that are licensed as open source software. For these components,
the contents of the respective open source licenses apply, as also stored in
the Software. The list of components with the terms and conditions of license
are available for reading before purchase and are also included in the
Software. The licensee receives a simple rights of use from the respective
right holders for using the open source software under the conditions as
provided for it by the respective valid license terms. The provided license
terms apply to only the components that are not licensed as open source
software.
All rights regarding
the usage and exploitation of the software and Software remain reserved to 3S.
§ 4 Warranty
4.1. The manufacturer warrants that the installed Software will
substantially conform to its documentation or data sheet. The following
restrictions shall apply. In particular, there is no warranty that the Software
fulfills the specific requirements of the user, serves his specific purpose and
works together with all the other programs selected by the user, in so far as
interfaces to these programs have not been agreed upon in writing.
4.2. It is deemed to be agreed and the user recognizes and
accepts that, according to the current state of knowledge and technology, it is
not possible to create software in such a way that it works without errors or
faults under all application conditions. A deviation from the agreed properties
of the Software can only be considered significant if normal operation is
substantially disrupted. If a disruption occurs under exceptional
circumstances, this cannot be considered as a deviation from the agreed
properties of the Software.
4.3. The
user shall immediately examine the Software supplied, shall establish its
appropriateness for the intended purpose and shall immediately issue complaints
about initial or non-initial errors/defects in detail and in such a way that
the error/defect can be reproduced by the manufacturer. The user agrees to
provide 3S with material giving information on the nature and occurrence of
these errors/defects in order to contribute to their localization and
correction. The user bears sole responsibility for the selection, installation
and use of the Software, as well as for the intended results thereof.
4.4. The manufacturer does not provide a warranty for errors or
defects that are caused by or result from the following circumstances:
(a) Incorrect or insufficient maintenance or parameterization
(b) Operation outside the software’s specification
(c) Incorrect preparation and/or maintenance of the installation
location
(d) Interaction with hardware or software not released by the
manufacturer
A special
guarantee which could result in additional rights is not provided.
4.5. Any defects with regard to the supplied Software (including
defects with regard to the program description and any other documents provided
along with the Software), will be rectified by the manufacturer within an
appropriate period of time. The manufacturer has the right to decide between
rework/repair free of charge or replacement at its own discretion.
4.6 The conditions for liability and warranty in these license
terms are valid for the complete Software with respect to the manufacturer. The
liability and warranty conditions of the open source licenses are valid between
the user and the open source right holders.
§ 5 Limitation of Liability
The Software can
be used for numerous applications. The user shall decide independently whether
or not it is also appropriate for the actual intended application. After
installation, the user is responsible for the Software functioning according to
its specifications.
The manufacturer
is liable for intentional acts and gross negligence. The manufacturer shall be
liable for slight negligence only if this involves the breach of a major
obligation deemed essential for the purpose of the contract (cardinal
obligation) and the fulfillment of which the customer may regularly rely upon
or for damages resulting from injury to life body or health. The manufacturer
is obliged to act with due diligence.
Upon the
determination of whether the manufacturer has culpability, it is to be
considered that, as a matter of fact, it is not possible to provide software on
an error-free basis. For events of slight negligence, total liability is
limited to the amount of the foreseeable damage, the occurrence of which must typically
be expected; however, the maximum of such liability arising from the
contractual relationship is limited to a total of EURO 100,000.00. The
manufacturer shall not be liable for other damages, consequential damages, or
lost profits.
The preceding provisions
also apply in favour of any vicarious agent of the manufacturer. Liability
under product liability law remains unaffected. For the loss of data and/or
programs, the manufacturer is not liable insofar the damages are based on the
fact that the user refrained from conducting data security measures and thereby
ensuring that the lost data could be restored with a justifiable expense.
Before commissioning the device and an application written with the CODESYS
Development System, the user is obligated to perform sufficient tests in a safe
environment.
§ 6 Termination
For non-time
limited software this Agreement may be terminated at any time by uninstalling
from the device the described Software from the manufacturer and destroying all
copies thereof.
If the software
is limited in time (subscription or subscription), the user agreement ends with
the termination of the subscription or subscription on the expiry date of the
agreed period of use. The termination of the time limited use can take place at
any time, but must take place at the latest one month before the end of the
expiration of the temporal limitation, in order to still be effective at the
end of the current subscription period. If this does not take place or is done
too late, the period of use is automatically extended by the period of the time
limit agreed in the data sheet. After the end of the period of use, the
functions of the software are no longer available or are only available to a
very limited extent.
§ 7 Governing Law
This License
Agreement shall be governed by the laws of the Federal Republic of Germany
excluding CISG. The place of performance and the court of jurisdiction for all
disputes arising from or in connection with this agreement is
87439 Kempten (Germany). Claims may also be asserted against each
contracting party in its general place of jurisdiction.
§ 8 Severability Clause
Should one
provision of this contract be or become invalid, or should the contract contain
a gap, the validity of the remaining provisions shall remain unaffected. In
place of the ineffective provisions, or in order to fill the gap, a provision
shall apply which, in so far as legally viable, approaches the original
intention of the contractual parties as closely as possible, or what can be
assumed to have been their intention if they had considered the point in
question.
ith this library, you can start your IoT Project within minutes. You can send your data from the field to the cloud or request it. There is no 3rd Party software installation required. The communication is directly established with the Dweet Pro or Dweet Service; both are acting as a cloud gateway.
Each PLC needs to be registered as a “Thing”. So it’s possible to communicate with different “Things”, no matter if it’s a PLC or other device. Data is exchanged in the open-standard format JSON. So you can integrate the data easily to existing software products.
The product is coming along with a detailed documentation and a Quick-start guide (https://pfaendergmbh.atlassian.net/wiki/spaces/Dweet/overview). So you can start to use this library together with the dweet service within a really short time. The library can be tested without any fees!
Features and Use-Cases
Establish an industry secure connection between your PLC and the dweet Pro cloud service with TLS. The whole data connection from your PLC to the dweet service is completely encrypted.
There are several options, to configure alerts directly in the cloud. Set Real-time notifications that keep you informed. It’s possible to set up E-Mail alerts directly from the Dweet Pro Cloud. Data can also be used to configure SMS or text-to-speech messages from another cloud providers.
Store data up to one month, without the need of physical storage.
Use cloud services to visualise your data or build it by your own. Connect quickly to freeboard.io and create a cloud visualisation within minutes.
Communicate with devices in different locations.
For data exchange, the open-standard JSON format is used.
