Core functions and features

High performance computing and precise control

Equipped with a 32-bit ARM Cortex-A9 processor and an 800MHz clock frequency, coupled with a minimum control cycle of 0.1ms, it can efficiently run complex control logic and algorithms. For example, in the automotive welding production line, the action timing of multiple welding robots can be synchronously controlled, and the action deviation can be controlled within ± 0.5mm to ensure welding accuracy; At the same time, the 16MB Flash storage capacity can accommodate up to 1000 control program blocks, meeting the program storage requirements of medium-sized control projects without the need for additional expansion of storage modules.

Flexible I/O expansion and system adaptation

Through 2 PCIe expansion slots, it can be flexibly matched with AC500 series AI771 analog input module (supporting thermocouple/thermistor signals), AO772 analog output module (4-20mA output), DI751 digital input module, etc., with a maximum expansion of 256 I/O channels. For example, in the food and beverage filling production line, 16 analog input channels can be expanded to collect filling pressure and liquid level signals, and 8 analog output channels can be used to control the opening of the filling valve, achieving full process control from raw material transportation to finished product filling, without the need to replace basic units to adapt to different production process requirements.

High reliability communication and data exchange

Built in 2 Gigabit Ethernet ports and 1 RS485 serial port, supporting multi protocol communication and dual network redundancy function. In the intelligent warehousing system, real-time communication with stacker cranes and conveyor controllers can be achieved through Profinet protocol, transmitting data such as cargo location and operating status at a communication rate of up to 1000Mbps, ensuring no delay in data transmission; At the same time, the dual network redundancy design can switch to the backup network within 100ms in the event of a main communication network failure, avoiding storage operations from stalling due to communication interruptions and ensuring the continuous operation of the system.

Data Protection and Fault Diagnosis

Supports external 24V DC backup power supply. When the main power supply is interrupted, real-time data in RAM (such as production counting and equipment operating parameters) can be saved for up to 72 hours. After power is restored, there is no need to reinitialize the system, and normal operation can be resumed directly, reducing data loss and production interruption losses. In addition, the built-in comprehensive fault diagnosis function can detect the fault status of the processor, memory, communication interface, and expansion module. The fault code (such as "E01: Ethernet port 1 fault" and "F03: Expansion module communication interruption") can be uploaded to the upper computer through Ethernet, and the staff can quickly locate the fault point, reducing the fault investigation time by more than 50%.

Industrial grade safety and environmental adaptation
