FAQ Question?What is the UNI-TELWAY protocol and which PLCs use it?AnswerUNI-TELWAY is a proprietary fieldbus protocol developed by Telemecanique (now Schneider Electric). It was widely used for communication between PLCs, HMIs, and other devices in the Modicon TSX series, particularly the Modicon Premium and Quantum platforms, before being superseded by modern protocols like Ethernet/IP. Question?What is the purpose of the ‘TER’ and ‘AUX’ connectors on this box?AnswerThe ‘TER’ connector is for the main bus line termination or through-connection, ensuring signal integrity across the network. The ‘AUX’ (Auxiliary) connector typically provides a drop-line or tap-off point to connect a specific device to the bus. Question?Is this TSXPACC01 box compatible with modern Ethernet/IP or Modbus TCP networks?AnswerNo, the TSXPACC01 is designed exclusively for the physical and electrical standards of the UNI-TELWAY bus. It is not compatible with Ethernet-based protocols like Modbus TCP or Ethernet/IP. A protocol converter or gateway would be required to integrate a UNI-TELWAY device into a modern network. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
