1 Introduction
1.1 About this Document
COMX means Communication Modules netX. These modules provide a universal and easy to use
fieldbus interface for integration on various host systems. Through the set of standard application
interfaces and the same board dimensions in each COMX family it is easy to switch between the
different fieldbus systems, e.g. PROFIBUS DP, CANopen, DeviceNet, CC-Link or Ethernet by
changing the module.
This manual describes only the hardware part of the modules.
The COMX communication modules is a generation of Modules and offer beside fieldbus commu-
nication also Real-Time Ethernet communication. The application interface is different (not com-
patible) compared to COM Modules. The application interface of the COMX Modules is common to
all our COMX communication modules, and PC cards CIFX and netJACK communication modules
described in our toolkit manual, dual-port memory interface manual and the Real Time Ethernet
respectively fieldbus related details are defined in our Protocol API Manuals.
COM Modules are the previous generation of communication modules. The COM Modules are de-
scribed in an own manual. The following two tables give a comparison of both COM and COMX
Modules.

Description of COMX Modules
All COMX have a powerful processor and a complete fieldbus respectively Real-Time Ethernet in-
terface including isolated drivers and the connector according to the standard.
All boards require only a single stabilized 3.3 Voltage. All other voltages are created by DC/DC
converter on the COMX Module.
The access to the COMX Module is through the dual-port memory which can be easily integrated
as a static memory device. It has a non multiplexed 8 or 16 bit data bus with several control lines to
the host system. Between the COMX Module and the host system it is possible to generate inter-
rupts for data handling.
Generally the firmware and the configuration data are stored permanently in FLASH memory by
loading the data through the dual-port memory.

1.5 Module Names
The following table lists all COMX modules. The range of products will be expanded with COMX
modules with netX 10 or with netX 51. As a result of this expansion, it was necessary to rename
the existing COMX modules by adding ‘100’ to the name, which indicates that netX 100 is used on
the module respectively by adding ‘50’ to the name, which indicates that netX 50 is used etc.

After mounting the COMX-CA Module parallel at a basis board the rotary switches, LEDs and the
fieldbus connector are on the top side and are angled to the basis board. The edge of all front ele-
ments are in one layer which is 2.5 mm ahead of the edge of printed circuit board of the COMX
Module.
The COMX-CN Module has to be used if the mechanical dimensions or order of the LEDs,
switches and fieldbus connector does not fit. In that case you have to place these components di-
rectly on the motherboard and feed the signals to the connector X2 of the COMX-CN Module.
Note Please take care on the isolation distance, because the optical isolation interface is on
the module!
Especially for 12 MBit PROFIBUS the distance should be as small as possible.
For Ethernet the signal traces should run parallel and should have the same length.
Please refer at the fieldbus standards for further information!
2.2.2 Mechanical Dimensions of COMX Modules
The COMX Module has a board size of 30 x 70 mm.
The maximum height of the components at the top side of the printed circuit board is 14.0 mm in-
cluding the fieldbus connector which is also the component defining the height of the CA type. For
the CN type, the parts defining the height of these modules are the DC/DC converter and the trans-
former.
In order to assure the long-term availability of the modules, Hilscher claims the right to perform a
redesign if necessary due to changes in availability of components and to exchange these compo-
nents by similar ones which might differ in their dimensions.
In detail, the current minimum space requirements are given by the following table right below.
COMX Module Minimum required space on top of top side of the printed circuit board
CA type 14 mm
CN type 9 mm
Table 7: Minimum Required Space on top of Top Side of the Printed Circuit Board
However, in order
to be able to exchange a COMX module against any other type of COMX module later
and to be sure that future COMX modules which might have been affected by a redesign will
fit under any circumstances
and to avoid thermal problems,
we urgently recommend to obey the following rule:
Note: Keep the space of 14.0 mm above the top side of the COMX modules free.
At the bottom side the maximum height is 4.0 mm, therefore you have 2.5 mm space for compo-
nents on the host board below the module. The power dissipation in that area should be less than
330 mW!

For further module development please reserve additional 10 mm space behind the module. There
are a few larger fieldbus interfaces which does not fit on the small board space. In that case a sec-
ond printed circuit board will be mounted on top of the module and the 10 mm space is necessary
for the connection with flex stripe between these boards.
