Working Principle: The CPU350-BC utilizes an advanced microprocessor to execute the user program in a continuous loop. Its enhanced floating-point unit accelerates mathematical operations, while its expanded memory buffer allows for larger data tables and longer programs. The module manages the backplane bus to communicate with local I/O modules and expansion racks, coordinating real-time control across the entire distributed system.
Installation Requirements:
- Baseplate: Must be installed in a compatible Series 90-30 CPU slot on a 5-slot or 10-slot baseplate (e.g., IC693CHS391).
- Power Supply: Requires a high-capacity power supply to support the increased current draw of the CPU and expansion racks.
- Jumper Settings: Verify and configure hardware jumpers for memory protection, serial port termination, and baud rate before applying power.
- Clearance: Maintain at least 1 inch (25.4 mm) of clearance above and below the module for adequate airflow.
Usage Precautions:
- Software Compatibility: Ensure the programming software (Logicmaster 90, VersaPro, or Proficy Machine Edition) is updated to support the CPU350 feature set.
- Battery Backup: The CPU requires a functional battery to maintain the real-time clock and memory during power cycles.
- Grounding: Properly ground the baseplate to ensure noise immunity, especially when utilizing floating-point math and high-speed communications.
- Firmware Updates: Check for available firmware updates to resolve known bugs and enhance system stability.
