DIOLINE PLC - Lütze Transportation GmbH


The DIOLINE PLC is a flexible, powerful compact control. It was developed exclusively for use in rail vehicles. The controls are freely programmable in a convenient IEC 61131-3 development environment, and have an L-bus interface for the connection of local I/O modules.

The DIOLINE PLC can be used to automate simple vehicles, as a subsystem controller or as a powerful gateway to implement various vehicle-specific bus signals.

The integrated fieldbuses are available in the following designs:

  • MVB Slave Class 1.3 as EMD or ESD+
  • CANopen Master or CANopen Slave
  • SAE J939 or CAN2.0
  • RS485
  • Ethernet TCP/IP
  • Ethernet/IP

The Ethernet interface also serves as a programming, visualization and diagnostics interface. In addition, the DIOLINE PLC has an SD card slot that allows diagnostic data to be exported quickly and easily or updates of firmware and software to be carried out in the field, without needing a computer or software.

The DIOLINE PLC can be used both as a gateway with additional control tasks and also as a full subsystem control system. Here created programs can easily be ported onto the available versions if different field buses are used in different projects.

By adopting existing concepts for complex functions such as ambient data storage, load regulation or diagnostics, the time-to-market duration is reduced to a minimum. Further communication protocols (e.g. MODBUS, Profinet) are available on request.
