Description of COM Modules
All COM-C have a powerful processor and a complete fieldbus interface including isolated drivers
and the connector according to the standard. The slave modules have additional rotary switches to
set up the station address.
All boards require only a single stabilized 3.3 Voltage. All other voltages are created by DC/DC
converter on the COM-C Module.
The access to the COM-C Module is through the dual-port memory which can be easily integrated
as a static memory device. It has a non multiplexed 8 bit data bus with several control lines to the
host system. Between the COM-C Module and the host system it is possible to generate interrupts
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 or the serial diagnostic line.

Note:
The COM-CA-SCEB has only the special communication interface chip SERCON 816
on board. Programming of this chip must be done directly from the host application.
The description of the communication interface chip SERCON 816 can be get from the
‘SERCOS International’.
