　　The IC697CPX772 is a central processing unit (CPU) module in Emerson Automation's 90-70 series Programmable Logic Controller (PLC) family. The module is specially equipped with multiple communication interfaces, one (1) RJ11 serial communication interface and two (2) 9-pin D-shell RS485 communication ports. The processor supports SNP slave, interruptionless SNP (slave), SNPX, and RTU serial protocols.

　　The processor has 512 KB of built-in random access memory (RAM) and 256 KB of non-volatile flash memory. The processor supports floating-point computation, which is the data format used in actual calculations and transactions, because floating-point mathematics supports decimal values. It can accommodate up to 2K discrete inputs and any combination of discrete outputs as well as 8K words of analog input and output data.

　　The processor is equipped with an 80486DX4 microprocessor with a clock speed of 96 MHz. For Bollean execution, each Boolean instruction is executed at 0.4 microseconds. It also comes with a battery-powered real-time clock (RTC) with an accuracy of +/- 3.5 seconds per day and a maximum and elapsed time clock accuracy of +/- 0.1%. The module's lithium battery, catalog number IC697ACC701, has a shelf life of 20 years when operating at 5 degrees and a memory retention period of 6 months. The IC697CPX772 has a current consumption of 3.1A and an operating temperature of 0-60 degrees Celsius.
