Core hardware specifications
Processor: Intel 80188, 10 MHz
User program memory: 16 KB (RAM), compatible with EPROM/EEPROM memory card backup program
Backboard 5V power consumption: 350 mA, power selection needs to include this power consumption
Scanning speed: 1K Boolean logic, approximately 0.4ms
Built in serial port: 15 Pin D-Sub, SNP/SNP-X protocol, used for programming downloads and connecting to HMI; The CPU itself does not have an Ethernet port, and an additional CMM321 module is required for Ethernet
Battery: 3.6V lithium battery IC693ACC301, maintaining RAM program and RTC real-time clock; Battery failure program lost
Working temperature: 0-60 ℃, IP20 inside the cabinet, does not support hot swapping
Total number of timers and counters: 680
IO and register resources
Discrete input% I: 512 points
Discrete output% Q: 512 points
Analog input% AI: 128 words
Analog output% AQ: 64 words
Register% R: 2048 words
Global variable G: 1280bit; Internal coil% M: 1024 bits; Temporary coil% T: 256bit; System status% S: 128 bit
core functionality
Logical operations, IO processing
Execute ladder diagram logic to handle all input and output of local rack, local expansion rack, and Genius remote IO.
Serial communication (local SNP)
15 Pin port, SNP protocol, connect programming software (Logicmaster 90/Proficy ME) to download and upload programs, and interface with HMI that supports SNP protocol.
The local serial port does not support Modbus RTU; Serial Modbus requires the installation of IC693CMM311; Ethernet requires the installation of IC693CMM321.
Multi rack system management
Manage host racks+up to 4 local/remote expansion racks; The intelligent communication module (CMM301/CMM302/CMM311/CMM321) can only be installed in the CPU mainframe slot and cannot be placed in the CHS392/CHS398 expansion rack.
Battery backup RTC real-time clock, output forced override function, fault diagnosis LED status indication (RUN/OK/BAT)
Software&Firmware
Programming software: Logicmaster90, Proficy Machine Edition (PME)
SFC sequential function diagram is not supported, only ladder diagram LD and function block FBD are supported
No hardware storage card slot, cannot use Flash card; Program backup relies on EEPROM/EPROM card accessories.
