Monitors 1 PROFIBUS network + ProfiTrace 2 streaming + OPC

The Head Station is the primary element of ComBricks and has to be inserted in the most left slot of the fixed backplane socket. It schedules the interaction between all modules and provides data storage and an Ethernet interface for the user.

Type 1A is the basic model and ALL Head Stations are hardware technically identical with type 1A.

Type 1B and 1C are enhanced types that contain a ProfiTrace core and advanced web server for permanent remote maintenance of the PROFIBUS installation over Ethernet (hardware is identical to type 1A).

  • Type 1A: NO monitoring capabilities, no streaming, no OPC

  • Type 1B: Monitors 1 PROFIBUS network + ProfiTrace 2 streaming + OPC

  • Type 1C: Monitors 4 PROFIBUS networks + ProfiTrace 2 streaming + OPC

For monitoring repeater modules or slave modules are required to provide PROFIBUS telegrams on the backplane network.
