About the Book
The present User Guide provides information on Sercos and describes the process of setting up a Sercos bus with the Modicon M262 Motion Controller, adding devices, configuring the network communication, configuring the individual devices, and commissioning the system with EcoStruxure Machine Expert Logic Builder.
Consult the appropriate User Guides for information on hardware and installation of the Modicon M262 Motion Controller as well as other equipment such as Safety Logic Controllers, drives, I/O devices, and on programming the motion application and safety-related applications.
This document has been updated for the release of EcoStruxureTM Machine Expert V1.2.5.

LOSS OF CONTROL |
|
oThe designer of any control scheme must consider the potential failure modes of control paths and, for certain critical control functions, provide a means to achieve a safe state during and after a path failure. Examples of critical control functions are emergency stop and overtravel stop, power outage and restart. oSeparate or redundant control paths must be provided for critical control functions. oSystem control paths may include communication links. Consideration must be given to the implications of unanticipated transmission delays or failures of the link. oObserve all accident prevention regulations and local safety guidelines.1 oEach implementation of this equipment must be individually and thoroughly tested for proper operation before being placed into service. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
1 For additional information, refer to NEMA ICS 1.1 (latest edition), "Safety Guidelines for the Application, Installation, and Maintenance of Solid State Control" and to NEMA ICS 7.1 (latest edition), "Safety Standards for Construction and Guide for Selection, Installation and Operation of Adjustable-Speed Drive Systems" or their equivalent governing your particular location.

|
UNINTENDED EQUIPMENT OPERATION |
|
oOnly use software approved by Schneider Electric for use with this equipment. oUpdate your application program every time you change the physical hardware configuration. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
For reasons of Internet security, TCP/IP forwarding is disabled by default. Therefore, you must manually enable TCP/IP forwarding. However, doing so may expose your network to possible cyberattacks if you do not take additional measures to protect your enterprise. In addition, you may be subject to laws and regulations concerning cybersecurity.
|
|
|
UNAUTHENTICATED ACCESS AND SUBSEQUENT NETWORK INTRUSION |
|
oObserve and respect any an all pertinent national, regional and local cybersecurity and/or personal data laws and regulations when enabling TCP/IP forwarding on an industrial network. oIsolate your industrial network from other networks inside your company. oProtect any network against unintended access by using firewalls, VPN, or other, proven security measures. |

Failure to follow these instructions can result in death, serious injury, or equipment damage. |
