Features of the IC695CPU315 include 20 Megabytes of battery-backed user memory and 20 Megabytes of non-volatile flash user memory. It has configurable data and program memory, as well as the capability of programming in Ladder Diagram, Structured Text, Function Block Diagram, and C. The IC695CPU315 supports auto-located Symbolic Variables that can use any amount of user memory. It also supports most Series 90-30 modules and expansion racks. The IC695CPU315 supports up to 512 program blocks and the maximum size for a block is 128 Kilobytes. This hardware has in-system upgradeable firmware and has two serial ports: an RS-485 and RS-232 serial port. The IC695CPU315 can carry out Ethernet communications via the rack-based Ethernet Interface module, IC695ETM001.

Specifications for the IC695CPU315 include power requirements of 1.0 Amperes (nominal) for +3.3 Volts DC and 1.2 Amperes (nominal) for +5 Volts DC. It has an operating temperature range between 0 and 60 degrees Celsius and a typica Boolean execution speed of 0.047 milliseconds per 1000 Boolean instructions. The IC695CPU315 has an elapsed time clock accuracy of 0.01% maximum and supports Modbus RTU Slave, SNP, and Serial I/O for serial protocols. This hardware has an IC695ACC302 Lithium Smart Battery that has a total battery life of 23 days; battery life in low state yields a lifespan of 15 days and a lifespan of 8 days in good state. With regard to installation of the IC695CPU315, it is important that the user not connect the battery until the CPU is installed in the rack and is powered on. After this point, the battery may be attached to either of the two terminals in the battery compartment. Once these steps are taken, the CPU may be powered down and normal battery back up operation will start. In an effort to save battery life, the user should not connect the battery for the first time until the CPU is powered up.
