37 Frequently asked questions / FAQ

General
Are the Kits in the product list really required?
NO, the Kits are just an easy step into the ComBricks world, because they contain all required components. You
can also order all items separately; Head Station, repeater modules, I/O modules, etc. Kits are also cheaper
than separate items.
Backplane
How many modules can I insert in the backplane?
ComBricks can handle 32 modules, but high speed modules can only be inserted in the first 10 sockets
(repeater and fiber optic modules). If you only have 5 high speed modules, the rest of the sockets can be
completed with regular modules (I/O modules).
What is the "Backplane Network"?
These are the 4 internal networks on the backplane that repeater modules utilize to transfer PROFIBUS
messages transparently to other inserted repeater modules who are locked to the same network number. Each
network can have its own masters, slaves and baudrate. They are completely isolated.

When I buy a module, is a backplane socket provided?
YES, with every module a backplane socket is provided. If you require more sockets because of spare parts, an
additional set can be purchased.
Installation
What is the default IP address after purchase or reset?
The default IP address is; 192.168.1.254. This can be customized through the web server of the Head Station or
the ComBricks Discovery Tool.
PROFIBUS PA Coupler Module
How can I make the PA Coupler Module transparent for 500 kbps?
You have to update the busparameters in the master. Keep in mind that some configuration tools cannot
handle the large Tslot values.
I cannot make my PA module working. What are the steps to take?
•
Head Station type 1C (for the monitoring).
•
At least 1 module with a DP master (RS-485 or Fiber Optic) or CommDTM class 2 master through the Head
Station.
•
At least 1 PA module.
•
All involved modules on the same network number.
•
After changing the network number, reset the ComBricks.
•
Power the PA module (check the respective LED).
•
If it is a floating power supply without ground (regular adapter), it is recommended to short the "-" and
GND on the power supply connector of the PA module.
•
Proper termination at the other end of the PA segment.
•
In some cases the PA cable should also be more than 1 meter (same as RS-485).
•
Verify "your" calculation of DC current with the current consumption stated in the web server (status
screen).
