Scheider ATV 320 drive communication with Schneider PLC M 340 using control expert

To establish communication between a Schneider ATV320 drive and an M340 PLC using Control Expert (formerly Unity Pro), follow these steps: Hardware Setup: Connect the ATV320 to the M340 PLC using Modbus RTU (RS485) or Modbus TCP/IP (Ethernet) based on the available communication options. Ensure proper wiring, IP addressing (for Ethernet), or serial communication parameters (for RS485). ATV320 Configuration: Configure communication settings (Modbus address, baud rate, parity, or IP address) via the drive's keypad, SoMove software, or Web Server. Set the control mode to enable network control. M340 PLC Configuration in Control Expert: Create a new project and configure the communication module (e.g., BMXNOC for Ethernet or serial communication modules for RS485). Define the ATV320 as a Modbus device (Slave for RTU or TCP/IP). Control and Monitoring Setup: Map the required Modbus registers for control (start/stop, speed setpoint) and feedback (status, frequency). Use READ_VAR and WRITE_VAR functions or Schneider’s prebuilt DFBs (Derived Function Blocks) for communication logic. Testing and Validation: Verify communication using diagnostic tools in Control Expert. Test the control and feedback by sending commands to the drive and reading its status.
