Purpose and Key Concepts

The Device Module facilitates seamless communication and data exchange with various field devices and industrial protocols, simplifying system architecture and enhancing connectivity. The configuration of the Devices module is performed on the sections: Protocols, Channels, Nodes, Points, and AccessType.

Protocols

Protocols are the rules governing the communication between devices. FactoryStudio supports a variety of communication protocols, both native and OPC-based. The selection of Protocols to use in your specific Project is on the Project Explorer, at Devices → Protocols.

Channels

The Device Module uses Channels to establish connections with field devices. Each channel is defined by a specific protocol driver and connection type, such as RS-232 or TCP/IP. Channels allow the module to access multiple devices (such as PLCs) using the defined protocol and interface. The configuration of Channels is on the Project Explorer, at Devices → Channels.

Nodes

Each device connected to the system through channels is called a Node. Nodes can be individual devices or groups of devices. Each node contains one or more Points. The configuration of Nodes is on the Project Explorer, at Devices → Nodes.

Points

Points are individual items that can be read or written from/to nodes. They can be registers, I/O values or variables residing in field devices (nodes). Each Point is bound to a specific Tag in the Project configuration.

AccessType

Each Point is associated with an AccessType, which defines the rules for reading and writing values for that Point, such as the polling rate, whether a read is performed on startup, and whether you write values to that Point. The AccessType allows users to configure how clients can access data points in the system.

How the Device Module Operates

Managing Channels and Nodes

Channels are responsible for managing communication protocols and drivers, while Nodes handle multiple threads pointing to the configured Channels. Understanding the relationship between Channels and Nodes is essential for efficient data exchange.

• Channels: Execute processes based on communication protocols and drivers, configuring the required protocol or driver for a specific device.
• Nodes: Perform multiple threads pointing to the Channels, ensuring efficient data exchange and minimizing latency.

Channels are created and configured to handle specific communication protocols and drivers. Nodes, in turn, manage multiple threads pointing to these Channels. This multi-threaded approach ensures efficient data exchange and reduces latency, allowing the system to scale and handle numerous devices simultaneously.

Nodes

Nodes are the devices or PLCs on the network that you communicate with. You can enter the settings for your nodes as usual through the Engineering Workspace. You can also import settings from an OPC server or from another data source. See "Importing PLC Addresses" below.

Organizing the Points with AcessTypes

Points are groups that point to Nodes and are responsible for transferring information between configured devices and FactoryStudio. AccessTypes are used to define the specific methods for reading and writing data point values at specific moments using polling. The number of data points you can configure is related to both the ProductModel that is configured for the project and your software license. This approach allows for optimized data exchange and minimizes latency.

• Points: Groups pointing to Nodes, responsible for transferring information between configured devices and FactoryStudio.
• AccessTypes: Define specific methods for reading and writing data point values at specific moments using polling

Handling Read and Write events

In a SCADA system, handling read and write events is crucial for the efficient exchange of data between the HMI, PLCs, and other devices. FactoryStudio facilitates these events by allowing users to configure access types, which define the specific methods for reading and writing the values of each data point. The access types can be configured to determine the polling rate, specify whether a read is performed on startup, and decide whether unsolicited input is accepted.

Configuring the Device Module

The Device Module in FactoryStudio plays a central role in managing communication between the HMI and devices in an industrial automation system. To ensure seamless integration and optimal performance, it is essential to properly configure the Device Module. This includes selecting the appropriate communication protocol, creating and managing device channels, and defining device nodes and points.

The typical configuration workflow for the Device Module has the following sequence:

Communication Protocol Selection

FactoryStudio supports a wide range of communication protocols to facilitate interaction between the HMI and various industrial devices. To select the appropriate protocol for your system, consider factors such as compatibility with the devices in your network, data transfer speed, reliability, and security requirements. Once you have determined the most suitable protocol, configure it within the Device Module to establish communication between the HMI and devices.

There are various befits in including the included Native Protocols, instead of having to acquired and maintain a third-party OPC Server to enable the connection. See the Page <<< Native vs OPC for more informant

Customizing the Pre-defined AccessTypes

FactoryStudio comes with several pre-defined access types that define the specific methods for reading and writing the values of each data point. To further optimize data exchange, users can customize these access types as needed. To customize pre-defined access types:

To configure access types:

• Go to Devices → AccessTypes.

• Do one of the following:

• To edit an existing access type, double-click a field.

• To create a new access type, click Create New.

• Enter or select information, as needed.

To understand the device module's AccessType tab, explore the AccessType Configuration section in Device Configuration.

Common Issues and Best Practices

Common #Issues and Solutions

#Issue ControlLogix PLC Type

In the PLC Address Import section under Devices > Points, it is important to ensure that the correct protocol option is selected when connecting ControlLogix PLCs. In some cases, the default option "Model OTHERS" may not work correctly, and it may be necessary to select a specific model, such as "Model 1756-L8X". If you encounter issues with a ControlLogix Channel not sending or receiving values, try changing the protocol option to the specific model and test the communication.

#issue Importing L5K from ControlLogix

In the PLC Address Import section under Devices > Points, it is important to ensure that the path and file name are correct when importing L5K files using the "From Filename" or "From Device" options. In some cases, the "From Device" option may fail, and it may be necessary to use the "From Filename" option with the L5K file to make it work correctly.

Best Practices and #Recommendations

#Recommendation - System Design

Plan and design your industrial automation system with scalability and maintainability in mind. Use a modular approach, separating responsibilities between devices, TagProviders, and other modules. This promotes efficient workflows and simplifies system management.
