1Product description
1.1 Introduction
ComBricks™ - The first PROFIBUS and PROFINET-based
automation system that unites network components, permanent
monitoring with ProfiTrace and remote I/O.
ComBricks is a modular system that allows a mix of automation
components on a backplane. Repeater modules can be inserted
next to a PROFIBUS slave and at the same time, in a web browser
over Ethernet, the condition of the installation can be remotely
inspected with ProfiTrace OE.
1.2 Application areas
•Remote maintenance station with ProfiTrace OE
•Modular repeater backbone with hot swap
•Transparent data hub (repeaters, fiber optic, RS-485-IS, DP slave, PROFINET, etc.)
1.3 Product features
•Drives 32 modules (10 high-speed modules)
•Wide range of modules available
•Hot swap and extendible
•Powerful web server
•ProfiTrace OE for monitoring 4 networks
•Multi-language
•DIN-rail mounting
•IP 20

ComBricks User Manual v6.4.0 | January 18| © PROCENTEC 11/219
1.4 Modular PROFIBUS repeaters
The current trend in PROFIBUS projects is to use segmentation with repeaters, fiber optic and ProfiHubs to
bridge the common faults of the end-user concerning his cabling difficulties. ComBricks adds another important
element; the creation of modular and random repeater hubs which can be maintained remotely with a
permanent internal ProfiTrace (see Fig. 1).
ComBricks is based on a backplane which can hold up to 10 hot swap repeater modules. Each module has one
or two channels (so a total of max 20 galvanic isolated transparent segments). Every channel can handle 31
PROFIBUS stations and maximum 1200 m cable length (depends on the baudrate). Fig. 2 illustrates some
configurations.
Each channel has a fail-safe circuit which ensures that the remainder of the PROFIBUS network continues to
operate correctly and that the availability of the installation remains optimal.
The connection of the bus cable allows for a high degree of flexibility as the repeater modules contain both a 9-
pin and screw connector.
It is possible to dynamically exchange equipment during operation. ComBricks is ideal for flow meters, pH
analysers, actuators, drives and especially motor control centres that make use of drawer systems.

1.4.1 Cable Redundancy
The bus redundancy technology of the repeater modules is very advanced. A redundant system can be built
using 10 parallel cables. This architecture provides extremely high availability. Most suppliers only allow 2
cables (see Fig. 3).

1.5 ProfiTrace OE - Remote monitoring in a web browser
Permanent and simultaneous monitoring of 4 PROFIBUS networks is a powerful feature of ComBricks. Global
projects and a shortage of (qualified) technical staff members are causing significant capacity problems.
ComBricks offers a solution by remotely monitoring PROFIBUS installations over the Internet and alerting the
user by email.
The user can simply connect surrounding PROFIBUS networks and every network can be set to a unique
baudrate. The modular technology of ComBricks enables the network to be monitored when multiple repeater
modules are installed. All transparent messages from the backplane are constantly analysed.
Up to 10 Repeater modules with 2 channels each (20 galvanic isolated segments in total) can be inserted into
the backplane. Using DIP switches or the web server, repeater modules can be assigned to a network group.
This ensures isolated communication from the repeaters which are assigned to other network groups; the
networks are not combined or connected in any way. Only the Head Station can see all networks groups.
1.5.1 Web server
A web server with a ProfiTrace shell visualizes the 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.
The monitoring and logging is performed by the repeater modules which are inserted in the backplane.
ComBricks is the first system that has integrated a busmonitor in network components. Deploying ComBricks
repeaters for regular automation means automatic availability of ProfiTrace OE.

1.5.2 Email
Email messages provide real-time alerts in the event of detected faults in the PROFIBUS communication. These
email alerts are easy to set up in the web server.
1.5.3 Channel List
A brand new functionality within ProfiTrace OE is the Channel List. It gives a detailed overview of all repeater
channels (segments) and all connected stations.
1.5.4 Comparison between ComBricks and ProfiTrace 2
The application area for ComBricks (ProfiTrace OE) compared to ProfiTrace 2 is completely different. ProfiTrace
OE should be seen as a watchdog and ProfiTrace 2 as the mobile analyzer to do on-site work.

1.5.5 Offshore applications
With satellite internet offshore PROFIBUS networks can be remotely monitored. Emails can inform the
mainland about the status of the installation.
These applications simplify maintenance and eliminate the hassle to fly an expert over to fix a possible
problem. On the LAN local technicians can also monitor the networks.
1.5.6 Mining applications
Because of the depth, gasses and inaccessible areas, ComBricks is required to keep the control room and the
experts on a distance to monitor the PROFIBUS installations.
Multiple WLAN routers can bring Ethernet up to the surface.
With DTM technology the devices can also be diagnosed and parameterized.

1.5.7 Robot cells
Robot cells are hazardous environments with many safety zones. Crossing a safety border can cause a machine
shutdown and restarting can take a long time. Measuring PROFIBUS remotely decreases costs and improves
human safety.

1.5.8 Logistics
In demanding high-speed applications, ComBricks is ideal. The technician does not have to touch the
installation and can measure the network from a distance. This is also convenient if the installation is behind a
high-security zone such as baggage handling systems at airports, or parcel handling systems.

1.5.9 Traffic control
When distance and downtime are critical factors, ComBricks can be very helpful. Difficult to reach speed
indicators above the highway can be monitored from the road-side control cabinet, or even from the control
room.

1.5.10 Cranes
Many harbour cranes use PROFIBUS. There cranes are huge and sometimes hard to reach. The whole crane can
be monitored remotely, which is especially useful if the crane is equipped with a WIFI connection.

1.5.11 Other applications
•Cross border installations
•Water treatment
•Long commissioning and test cycles
•24-7 service contracts
1.6 Output control
Relay- and digital output modules can be configured to respond directly to bus problems, such as bus voltage
too low, retries, syncs, master lost, diagnostics, etc.
This offers a multitude of applications to directly and independently act on the machinery when the bus
communication becomes unreliable. Especially when safety, human lives or the environment are at stake.
Power switches, hold switches, indicators, backup systems and LED towers are a few examples of machine
parts that can be hooked up to the relays. ComBricks is the only monitoring product that has the capability to
respond directly on the hardware with multiple relays.
•The Head Station already contains 1 relay.
•The relays can also be configured to be switched manually or on time.

1.7 CommDTM
The FREE ComBricks CommDTM offers FDT 1.2 based asset management tools a powerful Ethernet pass-
through to access PROFIBUS devices which are connected on ComBricks repeater modules.
The internal DP-V1 class 2 masters are able to drive 2 out of 4 networks. When a CommDTM connection is
closed, the user can enter another network. The 2 active networks are managed by 1 or 2 PC Ethernet
connections.
The CommDTM provides the same auto baudrate detection facilities as the famous ProfiCaptain. It detects all
busparameters before it goes online. An available master address is required.
