1.1 Scope and definitions
This manual provides installation, operation and maintenance instructions for the STP EtherCAT®
Interface (abbreviated to "EtherCAT Interface" throughout this manual). You must use the EtherCAT
Interface as specified in this manual otherwise the protection provided by the equipment may be
impaired. Edwards takes no responsibility for damage or injury caused by improper use of the
equipment.
Read this manual and the STP control unit manual before you attempt to install, operate or maintain
the EtherCAT Interface.
Important safety information is highlighted as WARNING and CAUTION instructions; you must obey
these instructions. The use of WARNINGS and CAUTIONS is defined below.
WARNING
Warnings are given where failure to observe the instruction could result in serious injury
or death to people.
Throughout this manual, page, figure and table numbers are sequential.
The units used throughout this manual conform to the SI international system of units of
measurement; where appropriate, US equivalent units of measurement are also given.
The following IEC warning labels/symbols appear on this Instruction Manual:
Warning - This symbol denotes general warning
Refer to accompanying documentation and instruction manual.
CAUTION
Cautions are given where failure to observe the instruction could result in minor personal injury or
damage to the equipment, associated equipment and/or process.

1.2 General description
The EtherCAT Interface acts as a gateway between the EtherCAT protocol and RS232/RS485 based
ASCII serial protocol used by the STP control unit. It realizes the remote control through EtherCAT
network. The EtherCAT Interface is integrated into the rear side of the STP control unit. The setting
switches, indicators and connectors for the EtherCAT are on the rear panel. Refer to Figure 1.
The EtherCAT Interface starts up after turning on the main power switch of the STP control unit.
