The hardware structure of this periphery is based on the adoption of extremely new CPU
CMOS with 32 bits developed specifically for the execution of the so-called “embedded”
applications.
The card uses flash memories to store archives of historical data and LOG files of events.
The Card has 1 RS485 gate for sensors and 1 RS485 gate (opto-isolated) for local networks
used for connections with local communication devices (configuration computer, terminals
and remote controls etc). As optional it is possible to install a PROFI BUS or ETHERNET
serial port for connection with the communication devices PROFI BUS and ETHERNET
respectively.
The card integrates a Real Time Clock (clock with date) that allows the software to storage
figures in a chronological order.
