X20(c)CP041x, X20CP0420 and X20CP048x

1 General information
The CPUs in the X20 Compact-S family are available in different variants. This way, customers get the product that
best meets the requirements of the machine – technically and economically.
The processor performance of the compact CPUs ranges from 166 MHz (compatible) to 667 MHz. The most
economical variant is equipped with 128 MB RAM, 8 kB nonvolatile RAM and a 256 MB flash drive. The most
powerful variant of the Compact-S CPUs achieves cycle times up to 400 µs. It is equipped with 512 MB RAM,
64 kB nonvolatile RAM and a 2 GB internal flash drive.
With POWERLINK, Ethernet, USB and RS232, the CPUs offer a wide range of communication options. An optional
CAN interface is also available. If the application requires additional interfaces, the CPU can be modularly expanded
by one or two X20 interface slots. This allows the entire product range of X20 fieldbus interfaces to be used.
The fanless, battery-free design of Compact-S CPUs means they are completely maintenance-free.
• ARM Cortex-A9 processor with 166 MHz (compatible) to 667 MHz and integrated I/O processor
• Depending on the variant: POWERLINK with poll-response chaining
• 2x onboard USB
• Up to 2 slots for modular interface expansions
• 128 to 512 MB DDR3 SDRAM
• 256 MB to 2 GB onboard flash drive
• Fanless
• No battery
• Extremely compact

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

6.1.1 LED "S/E" (LED "Status/Error")

This LED is a green/red dual LED and indicates the state of the POWERLINK interface. The LED states have a
different meaning depending on the operating mode of the POWERLINK interface.

6.1.1.1 Ethernet mode

In this mode, the interface is operated as an Ethernet interface.

Green Red Description
Off On The interface is in error mode (failed Ethernet frames, increased number of collisions on the network, etc.).
Note:
Several red blinking signals are displayed immediately after the device is switched on. These are not errors, however.

Green Red Description
Off Off Mode: NOT_ACTIVE
The interface is either in mode NOT_ACTIVE or one of the following modes or errors is present:
• The device is switched off.
• The device is in the startup phase.
• The interface or device is not configured correctly in Automation Studio.
• The interface or device is defective.

Managing node (MN)

The network is monitored for POWERLINK frames. If a frame is not received within the configured time window (timeout), the
