Product Description

Iono Pi is an extremely versatile Input/Output module which combines several digital and analog input lines, support for standard interfaces like 1-Wire and Wiegand and power relay outputs, typical of a modern PLC, with the incredibly powerful quad-core processor of the Raspberry Pi. Iono Pi adds other important features that are essential to use the Raspberry Pi for professional applications, like a robust power supply with wide voltage range (9-28V) capable of up to 4A output current at 5V, and a real time clock with lithium back-up battery. Iono Pi can be used for an incredible range of applications, from data acquisition and control, to home and building automation, as well as access control, hotel room control solutions, environmental monitoring and many many others. And software development is pure Raspberry Pi, with the constantly growing list of standard and proprietary software frameworks available on this platform. Iono Pi can be employed both in industrial and residential environments, for professional applications where extreme reliability, ruggedness and compliance with technical and safety directives are required.

The “Control Loop” library includes function blocks for process control. It consists of different elements that are assembled flexibly into a control structure. These include various differentiators and integrators, for which various anti-windup strategies are available. In this way, the structure of the created control can be derived from the selected components. Some transfer functions are also achieved according to this scheme. This library also provides an example for the use of nested object-oriented function blocks.

The library also contains several digital filters that can be used for signal processing. For this purpose, it is necessary to determine the rating parameters yourself.

The library contains two sample programs to read out the digital and analog input modules as well to control the digital and analog output modules via the I2C bus from the Raspberry Pi. See http://www.horter.de/ for more information.

The library brings nearly all programming commands of the KUKA language into the PLC. Existing option packages, e.g. KUKA.ConveyorTech or KUKA.VectorMove, can be addressed via the FBs of mxAutomation. PLCopen compliant FBs allow easy application.

The download contains four identical projects, each with a different fieldbus connection to the robot. (Profinet, Ethernet/IP, EtherCAT and UDP)

Features:

• CODESYS client library implementing MQTT protocol (version 3.1.1)
• MQTT client functionality
• Library completely written in IEC code, therefore independent from target system
• Publish: Payload of any type can be transmitted to a broker*
• Subscribe: Messages of any type from MQTT brokers can be received*
• Message classification via MQTT topics
• MQTT-QoS-Levels: * QoS0 (At-most-once) * QoS1 (At-least-once)
• Authentication with user name / password
• Auto-Reconnect is available if connection has been aborted
• Channel encryption via SSL (TLS v1.1 Client)
• Last will functionality
• Topic wildcards (+/#)
• For maximum supported message payload size, see global variable MQTT_GVL.MAX_PAYLOAD_SIZE

Currently not supported: * QoS2 (Exactly once)

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.
