Appendix 4.3 Link special relays (SB) and link special registers
(SW)
This section compares link special relays (SB) and link special registers (SW) between CC-Link IE Controller Network
and MELSECNET/H.
Some link special relays (SB) and link special registers (SW) have been changed for the CC-Link IE Controller
Network.
Verify the link special relays (SB) and link special registers (SW). ( Page 639, Appendix 4.5)
(1) Comparison of link special relay (SB)
Change the link special relay (SB) in a sequence program referring to the following chart.
In addition, the link special relay (SB) shown below is a list for a case when an assignment range is SB0000 to
SB01FF.
