【英文介绍】
PM891 is a high performance, large application memory processor module with a wide range of applications and multiple functions.
Here is a detailed explanation of the PM891:
The PM891 is a single chip unit equipped with a power supply, CPU board, and unit terminal. This unit contains a microprocessor and RAM memory for processing data and
storing information. At the same time, it also has a real-time clock function to ensure time accuracy and synchronization. LED indicators, INIT buttons and secure digital interfaces
provide a user-friendly interface for easy monitoring and operation.
In terms of communication, the PM891 is equipped with two RJ45 Ethernet ports (CN1, CN2) and one RJ45 serial port (COM4), making it easy to connect to the control network.
The COM4 port is isolated and dedicated to configuration tools, which gives users greater flexibility and convenience.
To further improve availability and stability, the PM891 supports CPU redundancy. This means that in the event of a failure or error, the standby CPU can quickly take over, ensuring
continuous operation of the system. In addition, the Communication Expansion Bus (CEX bus) is also installed on the device to support the expansion of the onboard communication
port with a communication interface unit. Redundant communication interfaces can also be used on the CEX bus, further enhancing the reliability and stability of the system.
Another notable feature of the PM891 is its optical module bus, which can connect up to seven groups of S800 I/O devices (each group contains up to 12 devices). This design allow
s the PM891 to handle more input/output signals, increasing the processing power and efficiency of the system.
The PM891 is a powerful and stable processor module with a wide range of applications. Whether in industrial automation, control systems or data processing, it provides outstanding
performance and stable operating experience. At the same time, its flexible configuration and expansion ability also makes it able to adapt to a variety of complex application scenarios
to meet the diversified needs of users.
