Control and Communication Network CC-LinkSafety Specification
Part 1. Overview/Agreement
1 Scope
This part of GB /Z 29496 describes the safety protocol specifications for CC-LinkSafety. CC-LinkSafety's security protocol to machine
Mechanical safety system safety data such as emergency stop signal applied to the CC-Link system.
This section applies to the field of automation and control.
In this section, new features added to CC-Link, shaded in the figures and tables, are in accordance with the security protocol. Develop the connection
To the safety equipment unit of the CC-LinkSafety system, ensure that functional safety standards (eg GB/T 20438) are met and passed through a third party
Certification organization testing.
