Web7 nov. 2024 · Modbus RTU is used as our communication protocol. These devices have a termination resistor that can be activated easily through the User Interface Software that we provide. In addition, we support many other industrial protocols with the Robotiq Universal Controller, such as: Ethernet/IP, TCP/IP, DeviceNet, CANopen and EtherCAT. WebThe simplest form of termination is line-to-line resistor across the differential input. In RTU mode the Modus protocol requires quiet periods on the communications bus for synchronisation. It is therefore important that the Modbus is not allowed to "float", i.e. unreferenced to 0 V, as this could lead to spurious signals due to noise pick-up.
