The controller communicates via a built-in COM port that can be configured for RS232 or RS485 protocols using internal jumpers. The RS485 mode supports multi-drop networks of up to 32 devices. The controller functions as a Modbus slave device. For integration, your system must match the baud rate, data bits, parity, and stop bits configured in the controller. If using Modbus RTU over RS485, you may need to set the internal jumpers to RS485 mode and possibly enable the termination resistor. Alternatively, if your system uses RS232, you can connect directly. For RS485 compatibility, an external converter like the Phoenix Contact model can be used, but wiring errors or configuration mismatches are common issues.
