Key Features and Benefits

• Custom Development: Allows ‘C’ applications to run on Rockwell FLEX I/O platforms.
• Versatile Serial Ports: Two fully isolated serial ports:
  • PRT1 (Application/Debug/Config): RS-232
  • PRT2 (Application): RS-232, RS-422, RS-485 (jumper-configured for direct or multi-drop communication).
• Flexible Design: Each port can operate independently, offering design flexibility.
• Ladder Logic Integration: Operates using simple ladder logic.
• Full Monitoring & Debugging: Supports configuration and monitoring via a debug port and user configuration file.
