System overview
UPS module is available in three variations:
 CX1100-0900
 CX1100-0910
 CX1100-0920
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.
