2 Product overview
2.1 Appropriate Use
The CX10x0 device series is a modular control system designed for top-hat rail installation. The system is
scalable, so that the required modules can be assembled and installed in the control cabinet or terminal box
as required.
The UPS Modules are designed to supply CX10x0 Embedded PCs and their bus terminals.
2.2 System overview
UPS module is available in four variations:
• CX1100-0900
• CX1100-0910
• CX1100-0920
• CX1100-0930
The UPS module is used for the uninterruptible power supply of CX CPUs and any connected CX
components. In the event of a failure of the external supply, the module ensures that the application software
can save important data, e. g. on a Compact Flash card, NOVRAM or in a database via the network. During
the UPS retention time, the machine or process can be transferred into a defined state, and the operating
system can be shut down. The retention time can be set via a rotary switch or via software.
The use of state of the art capacitors makes this UPS module – unlike other battery powered techniques –
absolutely maintenance-free and offers rapid charging. The module can simply added to a CX system. Only
a 24 V DC supply cable is needed. The 24 V DC output voltage of the UPS is protected against short circuit
and overload. The CX1100-09xx may be retrofitted on site. A DPRAM user interface provides options for
settings and UPS status messages.
The functionality of the UPS is therefore independent of the operating system to be used. No driver software
is required. The TwinCAT System Manager recognizes the UPS module automatically, and the UPS signals
are available to the PLC programmer. A controlled 24 V DC power supply unit with a minimum output current
of 4 A is required.
