Safety Remote I/O Modules

• Remote I/O modules that support safety functions of CC-Link IE Field Network
• Performs safety control when used together with the MELSEC iQ-R Series safety CPU

Safety protocol versions and safety communication standards

Safety communication of the CC-Link IE Field Network complies with safety communication standards (IEC61784-3). Please note that said standards of different publication year applies to each safety protocol version.

Safety protocol versions vary depending on the product types and firmware versions.
Please refer to the connectability of the master stations and safety remote I/Os below.
For how to check firmware versions, please refer to the relevant product manuals.

Connectability of the master stations and safety remote I/Os

• Safety protocol versions: 1 and 2

  Master station

  (safety CPU module): firmware version 29 or later
  (master module RJ71GF11-T2): firmware version 70 or later

• Safety protocol version: 1

  Master station

  (safety CPU module): firmware versions 01 to 28
  (master module RJ71GF11-T2): firmware versions 06 to 69

• Safety protocol version: 2

  Safety remote I/O: Model name ends with “-S1”
  NZ2GNS12A2-14DT
  NZ2GNS12A2-16DTE

• Safety protocol version: 1

  Safety remote I/O: Model name does not end with “-S1”

●: System configuration is possible;○: possible with constraints^*1;-: not possible

• *1.Although a system can be configured, it is not possible to newly acquire a certification from a third-party certification body. As compliance with the latest standard is required to acquire a certification, it is recommended that only products that support safety protocol version 2 be used when acquiring a certification.
