. 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.
