The industrial communication protocols supported by the Sitara AM series are EtherNet/IP and PROFINET. These are widely used protocols in industrial automation and control systems, offering real-time communication and data exchange capabilities.
EtherNet/IP is an industrial communication protocol based on the Ethernet standard and allows for seamless integration of control systems, devices, and networks. It supports both peer-to-peer and client-server communication modes and is widely used in industries such as manufacturing, oil and gas, and transportation.
PROFINET is another popular industrial communication protocol, designed specifically for industrial automation and control systems. It operates on standard Ethernet infrastructure and provides real-time communication capabilities, making it suitable for time-critical applications. PROFINET is commonly used in industries such as automotive, packaging, and food and beverage.
High Processing Power and Real-Time Capabilities
The TI Sitara AM series is designed to support a variety of embedded applications, including industrial automation. In this context, the processing power and performance of the AM series are key factors for developers to consider when selecting a processor for their industrial automation system.
The AM series is based on ARM Cortex-A9 processors, which are well-known for their high performance and low power consumption. This makes them ideal for use in industrial automation, where reliable and energy-efficient operation is crucial. Additionally, the AM series processors come with a range of features that make them suitable for real-time applications, such as hardware-accelerated floating point operations and low-latency memory access.
One of the key advantages of the AM series is its processing power. The AM335x and AM437x families, for example, offer up to 1GHz of processing speed, providing enough computing power to handle time-sensitive tasks in real-time. This is particularly important in industrial automation, where processes must be executed within strict time constraints to ensure smooth operation and safety.
In addition to its processing power, the AM series is designed with various performance-enhancing features that make it well-suited for industrial automation tasks. One of these features is the embedded PRU-ICSS (Programmable Real-Time Unit and Industrial Communication Subsystem), which provides dedicated programmable real-time I/O control. This enables developers to implement real-time control for different industrial communication protocols, such as EtherCAT, PROFINET, and PROFIBUS, without sacrificing processing power or performance.
The PRU-ICSS also supports motion control applications, providing specialized hardware interfaces for high-performance motor control. This allows developers to achieve precise and synchronized control of motors, even in complex industrial automation environments.
Another benefit of the AM series is its integrated peripherals, such as Ethernet and USB ports, which simplify system design and reduce the need for external components. This not only saves space and cost but also improves system performance, as the AM series processors have optimized interfaces for these peripherals.
Robust Networking Features
One of the key networking features of the Sitara AM series is its integrated Ethernet controller. This controller supports 10/100/1000 Mbps speeds, making it suitable for both fast and gigabit Ethernet networks. It also supports a variety of interfaces, including MII, RMII, and RGMII, for easy integration with different PHYs.
The Sitara AM processors also feature an integrated ARM Cortex-A8 processor, which can support real-time operating systems (RTOS) for deterministic communication. This is an important feature for industrial applications that require precise timing and synchronization between devices.
For EtherNet/IP, the Sitara AM series supports the CIP (Common Industrial Protocol) protocol, which is used for communication between devices in industrial automation systems. This allows for seamless integration with other EtherNet/IP devices and control systems.
In addition, the Sitara AM processors support the PROFINET protocol, which is commonly used in process control and factory automation applications. This protocol is based on Ethernet and provides a real-time communication system for connecting industrial devices.
The Sitara AM processors also offer a range of communication interfaces, such as UART, CAN, SPI, and I2C, for connecting to other industrial devices and sensors. This allows for flexible networking options and easy integration with existing systems.
Moreover, the Sitara AM series processors come with a number of software development kits (SDKs) and tools to help developers quickly and easily implement industrial networking protocols. This includes support for industry-standard communication stacks, such as EtherNet/IP and PROFINET stacks, as well as other common industrial protocols.
