1 General information
Compact CPUs are available with processor speeds of 200 MHz and 400 MHz. Depending on the variant, up to
256 MB RAM and up to 32 kB nonvolatile onboard RAM is available. A built-in flash drive is available to store up
to 2 GB of application and other data.
All CPUs come equipped with Ethernet, USB and one RS232 interface. In both performance classes, integrated
POWERLINK and CAN bus interfaces are also available. If additional fieldbus connections are needed, the CPU
can be upgraded with an interface module from the standard X20 product range. These CPUs do not require fans
or batteries and are therefore maintenance-free. 30 different digital inputs and outputs and 2 analog inputs are
integrated in the devices. 1 analog input can be used for PT1000 resistance temperature measurement.
•CPU is Intel x86 200/400 MHz compatible with integrated I/O processor

2 Coated modules
Coated modules are X20 modules with a protective coating for the electronics component. This coating protects
X20c modules from condensation and corrosive gases.
The modules' electronics are fully compatible with the corresponding X20 modules.
For simplification purposes, only images and module IDs of uncoated modules are used in this data
sheet.
The coating has been certified according to the following standards:
•Condensation: BMW GS 95011-4, 2x 1 cycle
•Corrosive gas: EN 60068-2-60, method 4, exposure 21 days

6.6 POWERLINK interface (IF3)
Compact CPUs X20CP1381 and X20CP1382 are equipped with a POWERLINK V2 interface.
POWERLINK
By default, the POWERLINK interface is operated as a managing node (MN). In the managing node, the node
number is set to a fixed value of 240.
If the POWERLINK node is operated as a controlled node (CN), a node number from 1 to 239 can be set in the
POWERLINK configuration in Automation Studio.
Ethernet mode
In this mode, the interface is operated as an Ethernet interface. The INA2000 node number is set using the B&R
Automation Studio software.

6.10 Data and real-time clock buffering
The CPUs do not use a battery. This makes them completely maintenance-free. The following measures make
operation without a backup battery possible.
Data and real-time clock buffering Type of buffering Note
Remanent variables FRAM This FRAM stores its contents ferroelectrically. Unlike normal SRAM, this does
not require a battery.
Real-time clock Gold foil capacitor The real-time clock is buffered for approx. 1000 hours by a gold foil capacitor. The
gold foil capacitor is completely charged after 3 continuous hours of operation.
7 CPU supply
A power supply is integrated in these compact CPUs. It has a feed for the CPU, X2X Link and the internal I/O
power supply. The supply for the CPU and X2X Link is electrically isolated.
The connections are located on the X3 I/O slot.
Power supply concept of Compact CPUs
To ensure proper operation of compact CPUs, the following items must be taken into consideration:
The supply concept Description
CPU and I/O GND The GND contact is provided 5 times on the terminal blocks of the integrated I/O slots. All GND contacts are connected to one
another. The GND contacts of the CPU and I/O power supply therefore use the same voltage.
Plug-in X20 I/O modules Supply of X20 I/O modules that can be connected to the compact CPU:
•X2X Link: Supplied by the CPU supply
•I/O channels: Supplied by the I/O power supply
Integrated X1 I/O slot All digital and analog signals as well as the RS232 and CAN bus interface are supplied by the CPU supply. Their operation is
therefore guaranteed even if there is no I/O power supply.
Integrated X2 I/O slot •All digital signals are supplied by the CPU supply. Their operation is therefore guaranteed even if there is no I/O power
supply.
•The encoder supply is supplied by the I/O power supply. If the encoder is not to be connected to the E-stop chain, then
it must be connected to an external power supply or it will be supplied by the CPU supply.
Integrated X3 I/O slot •All 12 digital signals are supplied by the I/O power supply.
•The status messages for each channel also work without an I/O power supply. This guarantees that status messages will
continue to be transferred during an E-stop.
•The status of the I/O power supply is indicated by a separate status message.
Caution!
Channels 5 to 8 are designed as mixed channels. If one of these channels is being used, it is absolutely essential to
ensure that there is no external voltage present on the I/O channel when the I/O power supply is cut off. Otherwise,
power will be regenerated back to the plus terminal of the I/O power supply via the I/O channel. This will result
in defective components.
The following solutions are available for preventing power regeneration from occurring:
•The I/O power supply of the CPU is not permitted to be switched off, which allows the reference potential
to be maintained.
•If the I/O power supply is switched off anyway (e.g. as part of the E-stop chain), then the sensor/actu-
ator supplies must also be switched off. This prevents potential power regeneration and protects com-
ponents from being destroyed.
