Hardware Specifications
Processor: AMD SC520 133MHz 32-bit, hardware floating-point operation
User memory: 240KB (shared by program and data), battery backup RAM, optional Flash memory card with fixed program
Scanning speed: 1K Boolean logic, typical 0.15 ms, one of the highest speed CPUs in the 90-30 series
Backplane 5V consumption: 1400   mA (1.4A), very high power consumption, power selection must focus on calculating the margin
Communication Interface
Dual RJ45 10/100M adaptive Ethernet ports, internal virtual switch, supporting daisy chain and DLR device level ring network; Same IP address
Equipped with RS-232 and RS-485 serial ports, native support for Modbus RTU master/slave, no need for CMM311 module
Battery: 3.6V battery, backup RAM program, RTC real-time clock; External high-capacity battery IC693ACC302 can be connected to extend the power-off storage time
Working temperature: 0-60 ℃ (IP20 inside the cabinet), does not support hot swapping
Firmware version: AE represents the firmware version of the CPU, which determines the protocol functionality; Programming software: Proficy Machine Edition (PME)

core functionality
CPU body built-in dual Ethernet (biggest highlight)
Difference between CPU 363/364/374: No need for CMM321 Ethernet module, CPU comes with dual network ports, saving host rack slot resources.
Protocol: SRTP (Programming Download), EGD Ethernet Global Data, Modbus TCP Master/Slave; Built in simple web page, allowing the browser to view CPU status information.
Dual network ports share the same IP, support daisy chain networking, achieve device level ring network DLR, and improve network reliability.
Native serial port Modbus RTU
Comes with RS-232/485, Modbus RTU master-slave station, interfaces with instruments and third-party devices, does not require CMM311.
Complete programming support
Support LD ladder diagram, FBD function block, SFC sequential function diagram, floating-point PID operation, and multitasking.
Supports intelligent modules such as Genius bus, Profibus DP master station, etc. The intelligent modules are only available on the CPU host rack.
RTC real-time clock, RUN/OK/BAT fault LED, output forced function.
