Modbus Serial Support

Modbus/Serial Support

EtherCAT is the system's real-time backbone and carries the cyclic process data see Hardware & EtherCAT. Additionally QiTech Control supports both Modbus RTU & TCP via QiTech Lib.

A device on a serial line (for example a USB serial port) is attached to a machine as part of its hardware the backend builds the machine's hardware from the serial port (generate_machine_hardware_from_serial). A serial line also carries Modbus RTU (below).
