DOCUMENT ORGANIZATION
The Beckhoff EtherCAT Slave Controller (ESC) documentation covers the following Beckhoff ESCs:

ET1200

ET1100

EtherCAT IP Core for Altera ® FPGAs


The documentation is organized in three sections. Section I and section II are common for all Beckhoff
ESCs, Section III is specific for each ESC variant.
The latest documentation is available at the Beckhoff homepage ( http://www.beckhoff.com ).
Section I – Technology (All ESCs)
Section I deals with the basic EtherCAT technology. Starting with the EtherCAT protocol itself, the
frame processing inside EtherCAT slaves is described. The features and interfaces of the physical
layer with its two alternatives Ethernet and EBUS are explained afterwards. Finally, the details of the
functional units of an ESC like FMMU, SyncManager, Distributed Clocks, Slave Information Interface,
Interrupts, Watchdogs, and so on, are described.
Since Section I is common for all Beckhoff ESCs, it might describe features which are not available in
a specific ESC. Refer to the feature details overview in Section III of a specific ESC to find out which
features are available.
Section II – Register Description (All ESCs)
Section II contains detailed information about all ESC registers. This section is also common for all
Beckhoff ESCs, thus registers, register bits, or features are described which might not be available in
a specific ESC. Refer to the register overview and to the feature details overview in Section III of a
specific ESC to find out which registers and features are available.
Section III – Hardware Description (Specific ESC)
Section III is ESC specific and contains detailed information about the ESC features, implemented
registers, configuration, interfaces, pinout, usage, electrical and mechanical specification, and so on.
Especially the Process Data Interfaces (PDI) supported by the ESC are part of this section.
Additional Documentation
Application notes and utilities like pinout configuration tools for ET1200 can also be found at the
