CX1100-000x | Power supply units and I/O interfaces 1:

A choice of four power supply modules is available for use with a CX10x0 system. The power supply of all other system components is ensured via the internal PC104 bus; no separate supply lines are required. However, the CX1100 components offer further important characteristics that go beyond a pure power supply: an integrated NOVRAM enables the fail-safe storage of process data, an LCD display with two lines of 16 characters each is used for displaying system and user messages. A 4 + 1 keypad enables user input without additional keyboard or input panel. Local I/O signals are connected via the CX1100-0002 power supply variant, to which all Beckhoff Bus Terminals can be connected, or via CX1100-0003, which in addition to the Bus Terminals enables the connection of Extension Box IExxxx type Beckhoff Fieldbus Box modules. The option to connect Bus Terminals or a fieldbus Box creates a control system with a very variable, expandable I/O level with large signal variety. The I/O data are stored in a DPRAM, which is accessible by the CPU via the system bus. The power supply units of the CX system can be changed in the field: If, for example, local I/O via Bus Terminals is required, CX1100-0001 can be replaced with CX1100-0002 in the field. EtherCAT terminals can be connected via the CX1100-0004 power supply unit. The I/O data are stored directly in the main memory of the CX1100-0004 CPU; a DPRAM is no longer required. The CX1100-0004 power supply unit for EtherCAT terminals can not be connected in conjunction with the basic CX1000 CPU module.

An overview of the power supply architecture and a detailed description of the general system components such as GCB, ACB, NOVRAM, display and keypad can be found in the documentation for the power supply units.
