1.4 Technical Features
Common Technical Features for COMX
All leading Fieldbus and Real Time Ethernet Protocols available as Master and Slave
One common hardware for all Real Time Ethernet Protocols
Easy to use dual-port memory interface, with additional serial and diagnostic interface
USB or serial diagnostic interface at COMX
Host interface is designed for 8 KBytes (COMX 10) and for 16 KByte (COMX 50 and COMX
100) address space of the dual-port memory with selectable bus width of 8 or 16 bit.
3.3 V power supply reduces power consumption
Small footprint for the host connector with 50 mil grid
Solid mechanical assembly and a massive connection to earth ground by metal blocks spe-
cial design for the requirements of the modules with fieldbus connector
Two dowels for exact mounting of the module on the host board
Metal blocks can easily modified for special customer requirements
Front panel can be mounted on the metal blocks that the modules have always the same
front size and covers the fieldbus connector
Many modules are available in extended temperature specification (operating temperature
range -20°C … +65°C)
COMX 10 modules have address switches to set the bus address
COMX 10 and COMX 51 modules offer a serial dual-port memory mode as interface to the
host
CA and CN Types of COMX Modules
For the COMX family, Hilscher offers modules with angled and without fieldbus connectors:
COMX 10CN and COMX 100CN
COMX Modules without fieldbus respectively Ethernet connector
COMX 10CA, COMX 50CA, COMX 51CA and COMX 100CA
COMX Modules with angled fieldbus, Ethernet respectively fiber optics connector
