Repeater modules
Are the ComBricks repeaters suitable for PROFIsafe networks?
YES, especially in combination with the repeater redundancy makes ComBricks a perfect infrastructure
component for PROFIBUS safety networks. Remote maintenance with ProfiTrace OE only makes it better.
Can ComBricks be used in MPI networks?
YES, MPI is using PROFIBUS FDL telegrams with its own user data implementation. Every ComBricks repeater
and fiber optic coupler can interpret and forward MPI telegrams. Also the cabling rules are the same for MPI.
How are repeater modules powered?
All power is distributed over the backplane by the Head Station. The power to the Head Station is provided by
24V power connectors (redundant option).
How can I remotely deactivate a repeater module during operation?
Officially there is no shutdown function. What you can do is set the repeater network number by software
(web server) instead of dipswitches. When you want to shut it down, change the assigned network number to a
number that is not used. This will cause the repeater to be isolated from the rest.
With a Head Stations 1B (ProfiTrace for 2 networks) can I still wire 4 networks divided over 10 repeater
modules?
YES, ProfiTrace OE on a 1B Head Station will monitor network 1 and 2. There is no link with the repeater
modules which can be set to network 1, 2, 3 and 4.
I have changed the dipswitches on the repeater modules. How can I actualize them in the system without
removing the power on the Head Station?
You can soft start the system with the nav button on the Head Station or in the Device Management menu of
the web server. It is also possible to remove and insert the respective module.
When a slot contains a 1 channel repeater module can I hot swap it with a 2 channel repeater module?
YES, every time a module is inserted it is configured without looking at the past.
Is a 2 channel repeater module the same as a regular repeater?
YES and NO, Of course you have 2 RS-485 sides like a regular repeater, but there is a 3rd channel going to the
backplane to link up with the other inserted repeater modules. This means a 2 channel repeater module can
also be compared with a 3 channel repeater, but the 3rd channel is not RS-485. Additional to this; the RS-485
channels can also be assigned to networks. Then it cannot be compared at all with a regular repeater.
Is there an overview available how to connect the PROFIBUS cable with the repeater modules and when to
switch on the on-board termination?
This image illustrates the 4 configurations that we support:
In configuration A and C the cable starts at the repeater module. In configuration B and D the repeater module
is in the middle of the cable.
Only in configuration A the on-board termination should be set to ON. With the other configurations the
repeater module is in the middle of the segment or the termination is activated on the DB9 plug.
