The X-COM 01 communication module is intended for use in the programmable electronic 
system (PES) HIMax. 
The module is inserted into any of the base plate slots with the exception of the slots reserved 
for system bus modules. For more information, refer to the System Manual (HI 801 001 E). 
The module is approved for use in the safety-related HIMax system and can be used to 
transport safety-related protocols. 
The module ensures communication with systems via Ethernet and fieldbus interfaces with 
safeethernet and different standard protocols. 
Fore more information on how to configure the protocols and for details of the fieldbus 
interfaces, refer to the Communication Manual (HI  801 101 E). 
Use the SILworX programming tool to select the interfaces for the available protocols.
