COMbricks™ – The first PROFIBUS and PROFINET-based automation system that unites network components, permanent monitoring with ProfiTrace and remote I/O.

COMbricks 3D image

COMbricks is a modular device that is designed to be permanently installed in your automation system. COMbricks provides:

  1. Connectivity and functionality for PROFIBUS DP, PA, Intrinsically Safe RS485 segments, Fibre optic segments, PROFINET and even Foundation Fieldbus. Allowing the flexible implementation of repeaters, hubs, couplers and gateways in one compact unit.
  2. 24/7 network monitoring using built-in ProfiTrace functionality allowing up to four different networks with up to 20 segments to be simultaneously monitored from one unit. The monitoring functions can be accessed over standard Ethernet using a standard web browser. Giving:
    • remote monitoring of network performance and quality,
    • automatic notification of faults that occur on the networks,
    • pre-warning of performance degradation and impending failure,
    • OPC functionality built in allowing network monitoring to be easily integrated into SCADA and HMI systems.
  3. Remote control functionality with digital IO controlled remotely over PROFIBUS or Ethernet, or controlled from the ProfiTrace network monitor.
  4. Remote engineering access to your networked devices using the in-built commDTM software which can be used with modern FDT asset management and engineering tools such as Endress+Hauser’s FieldCare, ABB’s Asset Vision or PactWare etc.

ProfiTrace OE – Remote monitoring in a web browser

Web browser screens

COMbricks provides the powerful feature of permanent and simultaneous monitoring of up to 4 PROFIBUS networks. Monitoring includes ProfiTrace functions such as live list, statistics waveform visualisation and bargraph all accessible remotely via a standard web browser. Remote sites, global projects and a shortage of qualified technical staff are causing significant capacity problems. COMbricks offers a solution by remotely monitoring PROFIBUS installations over the Internet and alerting the user by email.

The monitoring and logging is performed by the repeater modules which are inserted in the backplane. COMbricks is the first system that has integrated the busmonitor and oscilloscope in the network components. Deploying COMbricks repeaters for regular automation means an automatic availability of ProfiTrace OE.

No-Software-LogoCOMbricks does not require special software. A web server with a ProfiTrace shell visualises information in an understandable format (ProfiTrace OE). Because of the web browser, additional software is NOT required and a constant connection with a PC to the COMbricks is NOT necessary.

E-mail messages provide real-time alerts should malfunctions be detected in the PROFIBUS installation. These can be easily set up through the web server.

A brand new functionality within COMbricks is the device location detection. It gives a detailed overview of all segments and the connected devices.

Modular PROFIBUS repeaters

The current trend with PROFIBUS projects is to use segmentation with repeaters, fibre optic segments and ProfiHubs to segregate segments and thus isolate problems caused by connector/wiring deterioration and pickup/EMC problems. COMbricks allows the creation of modular repeaters and hubs with any number of channels (up to 20). Further, every channel is monitored by the built-in ProfiTrace, accessible over Ethernet.

COMbricks repeater options

COMbricks is based on a backplane into which 10 hot swappable repeater modules, each with 1 or 2 channels, can be inserted (giving up to 20 galvanically isolated transparent segments). Every channel can handle 31 devices and maximum 1200 m cable length (depends on the baudrate).

The bus redundancy technology of the repeater modules is very advanced. A redundant system with up to 10 parallel network cables can be built. This architecture provides extremely high availability. Most suppliers only allow 2 cables.
