Key Functional Features

• High-Volume I/O Management: The CPU can manage up to 4096 discrete I/O points distributed across a maximum of eight baseplates. This allows one central processor to control a physically dispersed system without requiring multiple PLCs.

• Fast Program Execution: The 80386EX processor running at 25 MHz, combined with a scan rate of 0.22 ms per 1K of logic, enables the module to execute complex control algorithms and process large logic programs with minimal latency.

• Configurable Memory Architecture: The 240 KB of user memory is shared between logic programs and register data. The register memory is adjustable from 128 to 32,640 words, allowing the user to allocate space efficiently based on application needs for data storage or complex code.

• Flexible Communication Paths: While lacking a dedicated onboard serial port, the module uses the power supply’s RS-485 port for basic programming and HMI connections. Support for option modules adds Ethernet, Genius, and Profibus connectivity for integration into multi-vendor networks.

• Advanced Programming Capability: The CPU supports floating-point math for calculations involving real numbers, such as flow totalization or PID control algorithms. It also accommodates complex programming using a Sequential Event Recorder function block for high-speed event capture.

• Embedded Configuration for Small Systems: In entry-level applications with low I/O counts, the CPU can be embedded into the backplane, freeing all physical slots for I/O modules and reducing the system footprint.

Application Scenarios

• Mid-Range Machine Control: Used as the primary controller on automated packaging lines, material handling systems, and assembly machines where a balance of high I/O count, fast processing speed, and memory capacity is needed.

• Process Control Systems: Deployed in small to medium continuous processes, such as chemical batching, water treatment, and food processing, where it executes PID loops, manages analog signals, and logs data for regulatory compliance.

• Discrete Manufacturing: Applied in automotive, plastics, and textile industries for coordinating complex sequences involving robotics, conveyors, and actuators across a networked production line.

• System Retrofits and Upgrades: The IC693CPU360 is a direct performance upgrade for older Series 90-30 systems. The Extended Life version, IC693CPU360-EL, provides a form-fit-function replacement with long-term availability for critical infrastructure in power, oil and gas, and heavy industry.
