4.2 Transient Transmission Function
4.2.1 List of dedicated instructions and transient transmission range
(2) CC-Link dedicated instruction list and transient transmission range
(a) CC-Link dedicated instruction list
The CC-Link dedicated instructions that can be used for the CC-Link IE Controller Network module are listed
below.
For how to use CC-Link dedicated instructions, refer to the following.
Page 324, CHAPTER 9
*1 Check the serial No. and software version for applicability. ( Page 606, Appendix 3)
*2 Cannot be used if the own station is a safety CPU.
*3 Cannot be used if the own station or target station is a safety CPU.
(b) Transient transmission range of a CC-Link dedicated instruction
Communications are available with all stations on the same network, but not available with stations on other
networks.
