A new generation of communication Modules exists named COMX Modules and offer beside field-
bus communication also Real-Time Ethernet communication. The application interface is different
(not compatible) compared to COM Modules. The COMX Modules are described in an own manual
now. The following two tables give a comparison of both COM and COMX Modules.
