It is a version of the quad-core controller that is used with the QNX Neutrino operating system. TMR, Simplex, and Dual redundancy are supported by the component. The QNX operating system is used in high-speed, highly reliable industrial applications. Another type of technology used on this controller is Embedded Field Agent (EMA) technology, which allows Predix cloud-based applications and possibly web applications to be applied over a stable connection, allowing real-time data to be delivered to the connecting controllers.
IS420UCSCH1B Features
The controller comes with 4 GB of DDR3-1333 SDRAM, which is a type of memory used in computers and other digital devices for high-speed data storage. The controller has 5 Ethernet ports, which allow it to connect to other devices and networks for data transfer and communication. The controller uses ControlST as its Human-Machine Interface (HMI), which is a software application used to interact with and control the device.
The Mark VIe quad-core controller runs high-speed, high-reliability industrial applications using real-time hypervisor technology and QNX Neutrino, a real-time, multi-tasking operating system (OS). PredixTM cloud-based apps and/or locally hosted web applications are applied through a secure connection and delivered real-time data using embedded field agent (EFA) technology.
A software package tailored to the UCSCH1x controller’s use is preloaded. It leverages IONet interfaces as a turbine or balance of plant (BoP) controller and runs Mark VIe firmware and applications. Only supporting Mark controls I/O packs and controllers, IONet is a private special-purpose Ethernet. To synchronize the clocks of the I/O modules and controllers to within 100 microseconds, IEEE 1588 protocol is employed through the IONet interfaces.
With the IONet connections, external data is transmitted to and from the controller’s control system database. To the I/O modules, this also refers to process inputs and outputs. The UCSC controller lacks any application I/O, in contrast to conventional controllers that host application I/O on a backplane.
Operation
The operation of the system involves several key aspects, including the installation of the ToolboxST application, configuring the UDH network communication, and establishing the necessary IP address for communication with site HMIs. Here is an expanded explanation of these operations:
ToolboxST Application Installation: To facilitate configuration and management tasks, the ToolboxST application is typically installed on a minimum 4 GB unencrypted flash drive. This flash drive serves as the storage medium for the application and contains the necessary files and settings. The ToolboxST application provides a user-friendly interface for configuring various aspects of the system, including network communication.
UDH Network Configuration: The UDH (User Datagram Header) network is utilized for communication within the system. During the configuration process, the ToolboxST application is employed to define the communication parameters for the UDH network. This involves setting up network addresses, ports, protocols, and other relevant settings. The configuration ensures that the control module can establish reliable and secure communication with other devices and systems within the network.
Default IP Address: By default, the control module is assigned the IP address 192.168.101.111. This IP address serves as the initial configuration for the module’s network connectivity. However, it is important to note that this default IP address may need to be modified to match the specific requirements and setup of the site or network where the system is deployed.
Configuring Relevant UDH IP Address: In order for the control module to effectively communicate with the site HMIs (Human-Machine Interfaces), it must be configured with the relevant UDH IP address. This IP address is specific to the UDH network and enables seamless communication between the control module and the site HMIs. Through the ToolboxST application, the control module’s IP address can be customized and set to the appropriate value that aligns with the network configuration and addressing scheme of the site.
Virtual Network
The virtual network feature in controllers is a powerful capability provided by the hypervisor, enabling seamless communication and data exchange between virtual machines (VMs) running on the same physical machine or across multiple physical machines in the network. The virtual network functions similarly to a conventional Ethernet network, facilitating data transmission between VMs just as physical Ethernet networks facilitate data transfer between physical machines.
Virtual network plays a crucial role in connecting different components of the system and enabling efficient data transfer. Specifically, it facilitates data exchange between the Embedded Field Agent (EFA) and the Mark VIe control, both of which run as separate VMs on the UCSCH1 controller.
Here’s how the virtual network enables data communication between the EFA and the Mark VIe control:
EFA and Mark VIe Control VMs: In the UCSCH1 controller, the EFA and the Mark VIe control are both running as virtual machines (VMs) within the same hypervisor environment. Each VM operates independently, emulating separate computing environments within the same physical machine.
Data Transfer through Virtual Network: When data needs to be exchanged between the EFA and the Mark VIe control, it is transmitted through the virtual network provided by the hypervisor. The virtual network efficiently routes the data between the two VMs, enabling seamless and fast communication.
Connection to the Cloud: The EFA, being an essential component for remote monitoring and management, requires a connection to the cloud for data exchange with remote servers or cloud-based applications. This connection allows the EFA to send data to the cloud and receive commands or updates from the cloud-based systems.
Physically Managed Switch for Network Division: To maintain proper network segregation and security, a physically managed switch is used to divide the networks. The physically managed switch creates distinct network segments, ensuring that the Mark VIe control, which contains sensitive control data, remains isolated from the cloud network. This network division helps protect critical control systems from potential external threats.
By leveraging the virtual network, the controller achieves efficient and secure data communication between its different VMs, enabling seamless coordination and control of various components in the system. The integration of a physically managed switch adds an extra layer of security, ensuring the safety and integrity of critical control systems while allowing the EFA to establish connections with cloud-based systems for enhanced functionality and remote monitoring capabilities.
