This CPU is specifically built to handle applications requiring significant computational power and the flexibility to manage a large number of I/O points.

Memory and Data Storage

  • The module is equipped with a built-in user memory of 240 KB for program storage. The memory is allocated across various modules, and the actual memory available for user programs depends on the allocation to memory types such as Analog Inputs, Register memory, and Analog Outputs. This module utilizes RAM and Flash memory for data storage, offering a flexible and durable storage solution.
  • With the release of Firmware Version 9.0 and later, supports floating-point math, which enables it to handle more complex mathematical operations, enhancing its flexibility for advanced applications. The module also supports up to 2048 discrete inputs and 2048 discrete outputs and 2048 analog inputs and 512 analog outputs, making it ideal for large-scale automation systems.

Scan Rate and Performance

  • It offers a typical scan rate of 0.22 milliseconds per 1K of logic.
  • This scan rate ensures that the module can process large amounts of data quickly, making it well-suited for time-sensitive control processes. Additionally, the module supports up to 2000 timers and counters, providing a powerful tool for managing various process variables and elapsed time measurements.

 

Communication and I/O Capabilities

  • Equipped with three serial communication ports, which support SNP slave, RTU slave, and SNP/SNPX master/slave configurations. These communication capabilities make it easy for the CPU to communicate with other modules and devices within the system.
  • Additionally, the module supports SNPX slave connections, which is essential for establishing reliable communication between different components in a networked system.
  • This CPU also supports up to 8 baseplates per system, including one CPU baseplate and up to 7 expansion or remote baseplates, allowing for flexible system configuration. The support for PCM/CCM modules provides additional options for system scalability and customization.

Battery-Backed Clock and Programming Support

  • The module is equipped with a battery-backed clock, which ensures that time-related data and system configurations are preserved even during power outages. This feature is particularly valuable for systems that require accurate timing and continuous operation.
  • This CPU module also supports a wide range of programming languages, including ladder logic, sequential function charts (SFC), and C programming, offering great flexibility for different types of automation projects. Additionally, it is compatible with CIMPLICITY control software, a Windows-based software suite for easy configuration and monitoring.

Register and Analog Memory

The register memory (%R) and analog input/output memory (%AI and %AQ) are both configurable in 128-word increments. Depending on the version of the programming software, the total range for these memory types is:

  • DOS Programmer: Configurable from 128 to 16,384 words for register memory, and 128 to 8,192 words for analog input and output memory.
  • Windows-based software (VersaPro, Logic Developer-PLC, or Windows programmer 2.2): Configurable from 128 to 32,640 words for both register and analog memory.
  • This memory configuration allows users to fine-tune their system's memory allocation according to the size and complexity of the application.

Built-in Serial Ports and Communication

  • SNP/SNPX slave (on the power supply connector),
  • RTU slave,
  • SNP/SNPX master/slave,
  • Serial I/O Write (on Ports 1 and 2).
  • For additional communication capabilities, the system can utilize CMM (Communication Module) for CCM (Communication Control Module) support and PCM (Processor Communication Module) for RTU master support. These options expand the module's connectivity with other devices in the system, allowing for seamless communication and data exchange.

Features

  • The module operates with a 5V DC supply and requires a current draw of 890 mA from the power supply to function optimally. The module is designed to work within an ambient temperature range of 0°C to 60°C (32°F to 140°F), ensuring reliable operation in typical industrial environments. It is well-suited for systems that require a high degree of reliability in environments with fluctuating temperature conditions.
  • The module provides global memory of 1280 bits and register memory of up to 9999 words. Memory is also allocated for analog input and analog output, with 9999 words dedicated to each. The module also features internal coils with 4096 bits of memory and temporary output coils with 256 bits. This memory organization allows to handle complex operations while maintaining efficient memory utilization.
  • Supports more than 2,000 timers and counters, depending on the available user memory. These are used for measuring time intervals or counting events, essential in many industrial processes. Additionally, the CPU supports shift registers, which allow for the serial handling of data, enhancing its capability in applications requiring sequential data processing.
  • Support a maximum of 8 baseplates per system. This includes the CPU baseplate (which houses the CPU module) and up to 7 additional expansion or remote baseplates. This flexibility in configuration allows for easy expansion and customization, enabling the system to scale according to the needs of the application.
  • The module operates by drawing 890 milliamps from a +5 VDC power supply. This relatively low power consumption ensures energy-efficient while maintaining its high-performance processing capabilities. The power supply must be able to handle this load to ensure reliable operation across the system.
  • Powered by the 80386EX microprocessor running at a speed of 25 MHz. This processor type ensures high-speed computational capabilities, allowing the CPU to handle demanding industrial applications with ease. The 80386EX processor is well-suited for embedded control systems, offering efficient performance and reliability.
  • One of the critical performance metrics is its typical scan rate, which is 0.22 milliseconds per 1K of logic. This fast scan rate enables the CPU to process complex logic operations quickly, making it ideal for applications where real-time processing and responsiveness are essential.
  • Supports up to 2,048 discrete input points (%I) and 2,048 discrete output points (%Q), making it suitable for handling a large number of on/off signals. These points are crucial for controlling various devices such as sensors, actuators, and switches in automation systems.
  • The module includes 1,280 bits of global memory (%G) and 4,096 bits of internal coils (%M). These memory types are used for storing general-purpose data and internal control logic. It also includes 256 bits of temporary output coils (%T) for storing intermediate outputs, which may be used for internal operations or as temporary variables within the control logic.
  •  It also supports LAN communication with multidrop functionality, enabling it to interface with a range of network devices. Furthermore, it supports various communication standards, including Ethernet, FIP, PROFIBUS, GBC, GCM, and GCM+, which allow for broader system integration and enhanced flexibility in industrial automation environments.
  • The module includes an override function, which enables manual control over system operations, providing users with the ability to temporarily take control in specific situations. Additionally, it supports periodic subroutine interrupts, allowing the system to execute critical tasks at predefined intervals, which is especially useful in applications requiring regular updates.
  • A battery-backed clock is integrated into the module, ensuring that time-sensitive data is retained even during power failures. This feature is critical for applications where precise time tracking is necessary, such as scheduling operations or logging timestamps.
  • Utilizes RAM and Flash memory for data storage. RAM provides fast access to data, while Flash memory offers non-volatile storage for system configurations, ensuring that critical information is preserved even when the system is powered off.
  • The CPU supports floating-point math operations, which are enabled in firmware version 9.00 or later. This capability allows the module to handle more complex mathematical computations that are commonly required in advanced automation tasks, such as control loops, data analysis, and process optimization.
  • Compatible with PCM/CCM modules, which allow for additional communication and control functionality. These modules enable the CPU to support various communication protocols and expand its capabilities, making it a versatile choice for a wide range of industrial control systems.
