Hakko Electronics V Series User Manual

Appendix 2 n : 1 Connection (Multi-link 2) App2-1
Appendix 2 n : 1 Connection (Multi-link 2)
Multi-link 2
• One PLC is connected to a maximum of four V7 series.
• An original network is created where the V7 series (Local Port 1) that is directly connected to the
PLC is the master station, and other three V7 series are slave stations. Only the master station
makes communications directly with the PLC, and the slave stations make communications with
the PLC via the master station.
• Communications between the V7 master station and the PLC depend on the communication
speed set on the PLC. The maximum available speed for the V7 series is 115 kbps, which is
higher than the one available with multi-link connection described in “Appendix 3, n : 1 Connection
(Multi-link).”
