The ICU mod. 2 card with its Intel CPU provides high processing power for fast or complex calculation requirements. The card supports standard communication protocols via serial port (Modbus RTU) and redundant Ethernet communication (Open Modbus TCP, UDP). An integrated compact-flash memory allows extended data recording.
In SIL-certified safety systems, the ICU mod. 2 takes care of the communication between the safety components. The individual safety functions are processed by the intelligent I/O cards. Additionaly the safe input signals can be used directly by the ICU mod. 2 for control purposes.
