What Are BUS Communication Tests?

Often, the first step for establishing the test setup, a bus communication test, is a combination of real and simulated electronic control units (ECUs) used to test the bus communication. We partner with customers to establish their BUS communication testing needs and deliver complete automated test systems tailored to specific application, industry, and assembly production requirements.

BUS Communication Testing Methods

Peripheral BUS Communication

Peripheral BUS communication transmits data between peripheral devices and control systems such as keyboards, printers, and external storage devices. Testing BUS communication protocols such as Modbus, Profibus, and DeviceNet verifies the seamless data exchange between programmable logic controllers (PLCs), human-machine interfaces (HMIs), sensors, actuators, and other control devices.  Essential for industrial automation applications, our peripheral BUS testing systems ensure precise control and synchronization of machinery for efficient automated systems and factory automation.

System BUS Communication

A System BUS connects the processor (CPU) with the main memory (RAM), hard drive, I/O drives, and other essential chipset components for accurate data transmission in networked systems. In the automotive industry, this involves testing in-vehicle communication networks, including the Controller Area Network (CAN), Local Interconnect Network (LIN) protocols, and communication between Electronic Control Units (ECUs), sensors, actuators, and other vehicle subsystems.

Testing verifies the real-time data exchange between the engine management, transmission control, chassis control, infotainment systems, and various sensors for optimal engine performance and vehicle safety. By identifying and correcting communication issues, our testing solutions help customers enhance the reliability and efficiency of a vehicle’s electronic systems.

Internal BUS Communication 

Internal BUS communication testing verifies the real-time data exchange within a device’s internal components. Often used in embedded systems and consumer electronics, this involves testing BUS communication protocols such as inter-integrated circuit (I2C), serial peripheral interface (SPI), universal asynchronous receiver-transmitter (UART), and universal serial bus (USB). For example, our internal BUS testing systems can verify the seamless interaction between a smartphone’s microcontroller and various sensors, such as the accelerometer and gyroscope sensor. This ensures the device accurately processes user inputs and environmental data, enhancing the user experience.

External BUS Communication

External BUS communication testing ensures reliable data between devices and systems over external communication protocols such as Modbus, DNP3, IEC 61850, USB, Ethernet, or FireWire. Used to connect devices over longer distances, it is essential for renewable energy and power systems to verify data between a power grid’s Supervisory Control and Data Acquisition (SCADA) system and remote terminal units (RTUs). It allows energy companies to monitor and control energy generation, transmission, and consumption. By detecting and resolving communication issues early, companies can ensure uninterrupted power supply, grid stability, and efficient energy distribution.
