Installation Guidelines

• System Requirements: Ensure the workstation or programming device is running STEP 7 version V4.02 or higher prior to installation.
• Hardware Setup: Install the appropriate communication processor (CP 341 or CP 441-2) in the S7 rack before loading the software.
• License Management: The provided HW dongle must be connected to the system for the software to function correctly; do not remove the dongle during runtime.
• Configuration: Use the STEP 7 configuration tools to parameterize the communication processor to match the Modbus slave settings required by the host system.
• Verification: After installation, verify the communication link via the diagnostic buffers in the STEP 7 project to ensure correct frame processing.
