Product features of AC 800M processor unit

1: CPU and memory

- AC 800M processor unit provides a wide selection of CPU modules, such as PM851, PM856, PM860, PM861, PM864, and PM865. These modules vary in processing power, memory size, and redundancy support.

- Equipped with large capacity RAM memory for storing and running Firmware, control unit hardware configuration information, and applications.

2: indicates the communication interface

- Integrate two Ethernet interfaces (CN1 and CN2), support TCP/IP, and can be used to connect the master network and the control network. CN2 can be used for redundancy configuration.

- Equipped with two RS-232C interfaces (COM3, COM4), COM3 supports modem, can be used for a variety of protocol communication; COM4 is used to connect to the configuration tool.

- Support for ModulBus electrical and fiber extension interfaces, as well as the extension of various fieldbus modules (such as Profibus DP, Profinet IO, etc.).

3: Redundancy Settings

- Supports redundancy for key components, such as cpus and communication interfaces, to improve system reliability and efficiency.

- Redundant switching times are extremely short, ensuring a quick switch to a backup component in the event of a failure, reducing system downtime.
