In this course, you're going to learn about SCADA by creating graphical interfaces that you can use to monitor the automated processes, establish operating parameters, and even acquire data from a system that is already operated and functional.
Raspberry Pi Scada Interface
First, I created 2 lines of the "TCP-IP/TCP" type. The L.ModbusSrv line listened on port 502, at ALL address, which is a symbolic notation for listening on all network interfaces. The L.ModbusCliline was configured to connect to this port 502 on a loopback interface.
Once physical connectivity has been established, the Outpost will establish a secure connection to the AWS Outposts Service Anchor in the AWS Region over a Direct Connect public or private virtual interface, or the Internet. This connection creates the Outpost service-link that will allow the customer to seamlessly extend VPCs from the AWS region to their Outpost and carry customer traffic between VPC subnets on Outposts and VPC subnets, interface endpoints, and internet gateways (IGW) in the AWS Region. The service-link will also carry control plane traffic for AWS to monitor and manage the Outpost. If the service-link experiences a brief loss of connectivity, the PI System will continue to run locally without disruption.

Automated Solutions develops and sells software products for industrial and process automation. We also provide custom development services using our products for organizations that need custom HMI, SCADA, interface, or logging applications, but are short on development resources.
Compared to the ability of a simple microcontroller with raspberry pi, we can see more clearly its firepower. Most microcontrollers are capable of 8-bit words running at a few mega hertz frequency. On the other hand, raspberry version 3 has a 64-bit 1.2 GHz processor, not to mention WiFi, Bluetooth, 1 GB SDRAM memory, USB ports, HDMI output, among others.
Users can easily connect to any SQL database, and new configuration interfaces for FTP and SNMP allow you to quickly configure multimedia alarms and reports that can be sent to e-mail, smartphones, or a printer. InduSoft Web Studio offers the freedom to develop SCADA and HMI applications that can be easily and quickly deployed on any supported device.
The GLG Toolkit includes the GLG Graphics Builder - a graphical editor with point and click interface for creating dynamic HMI and SCADA screens and diagrams. With the Graphics Builder, developers can create elaborate process control and system monitoring drawings, define dynamic behavior and attach real-time data sources. A number of pre-built components and palettes are available for use as building blocks in the Builder. An optional GIS Map component is also available.
The RevPi Compact is an open source compact controller based on the Raspberry Pi. Equipped with the Raspberry Pi Compute Module 3+, the control system has a quad-core processor with 1.2 GHz, 1 GB RAM and 8 GB eMMC flash memory. The open platform concept (including full root rights) allows the user maximum freedom of design when implementing his projects. To connect sensors and actuators, the RevPi Compact is equipped with eight digital and analog inputs as well as eight digital and two analog outputs. Two Ethernet interfaces (each with its own MAC address) enable the device to be integrated simultaneously in two different networks. The device also has a 4-pole RS485 interface with screw terminals.
The two separate Ethernet interfaces of the RevPi Compact allow the device to be integrated into two different networks at the same time. For example, sensor data from the OT network can be transferred from the shop floor to the RevPi Compact via Modbus TCP and sent further into the cloud or a higher-level IT system using MQTT or OPC UA.
Modbus is a serial communication standard and has become a de facto standard communication protocol and is now a commonly available means of connecting industrial electronic devices. In Modbus RTU and Modbus ASCII RS485 is used as the physical layer. Its possible to use a Raspberry Pi as Master or Slave in Modbus applications, but a RS485 interface is needed. Our RS422 / RS485 Serial HAT is a fully galvanic isolated serial communication HAT designed for use with the Raspberry Pi and the perfect choice for such kind of applications.
You probably know that tcpdump allows you to grab packet captures from a network interface and save them to a file. If you prefer a GUI, you probably use Wireshark, which uses the same underlying library (libpcap) to grab the data. In fact, you can capture data using tcpdump and look at it with Wireshark, although there are other tools like tcptrace or Ngrep that can work with the output, also.
Simple control systems are panel-mounted and deployed on small discrete controllers, allowing the front panel to be directly viewed and the operator to manually intervene if necessary. These would originally be pneumatic controllers, but now nearly all are electronic. Networks of such electronic controllers communicate using industry-standard protocols to create complex systems. Networking permits the use of remote or local SCADA operator interfaces and enables the controllers to be cascaded and interlocked.
SCADA, a control system architecture, uses computers, graphical user interfaces (GUIs), and networked data communications to perform high-level supervisory management. The SCADA system administers the operator interfaces that monitor and issue process commands. Networked modules connected to other peripheral devices like discrete PID controllers and programmable logic controllers execute logic calculations and real-time control. These controllers interface with the machinery.
Input/output or I/O interface is the interaction between a central processing device, such as a PLC, and the input and output devices. Inputs are the signals or data received by the processing system from a digital input device, such as a switch, relay or contactor, and analog inputs from various sensors indicating the status of physical parameters, such as temperature, pressure, etc. Outputs are the signals or data sent from the processing system to digital output devices, such as an indicator, lamp, alarm, relay or contactor and analog output devices, such as motors, valves and proportional controllers, etc. 2ff7e9595c
