Product Introduction:

The backplane bus communication rate is constant 12Mbps, and the real-time and deterministic performance of the system is not attenuated by the increase of random frame and communication distance

The communication adopts the standard industrial Ethernet protocol Modbus TCP/IP specified in GB/Z19582-3, and the application layer adopts the open Modbus protocol, and the communication rate is not less than 100Mbps.

Ethernet supports IO scanning mode, which can automatically identify various devices on the Ethernet network, which is convenient for users to increase or decrease equipment online in real time and facilitate maintenance.

>>CPU memory can be expanded to 7MB, there is enough program space available >> The CPU has a built-in real-time clock that can provide time labels for all information

>> The CPU has plenty of registers to choose from

>> Integrated multi-processor in CPU module, main processor processing program operation, coprocessor processing communication,
