PROTOCOL-SPECIFIC INFORMATION
9.11 EtherCAT Slave
9.11.1 Overview
The EtherCAT slave driver allows an EtherCAT master (i.e. TwinCAT) to interact with the interface card
via cyclic exchange of I/O process data and acyclic requests. The cyclic I/O process data is entirely
user-configurable.
Other notes of interest include:
• EtherCAT is a dedicated real-time protocol and cannot coexist with other Ethernet (SUE) protocols.
• A USB connection is required for use with the studio.
• The lowest supported FreeRun Cycle Time is 1ms.
• Supports up to 32 transmit data words and 32 receive data words.
• Slave device profile 5001.
• The ESI file can be obtained from the included CD-ROM or downloaded from the product web page
.
