Note: For the fixed-buffer communication function (asynchronous) of MELSEC, refer to the
MELSEC documentation.
The physical line between the S10mini or S10V and MELSEC must be
exclusively used for high-speed I/O communications. Ensure that nothing is
connected to the physical line except for the S10mini or S10V and MELSEC.
When using two high-speed I/O communication channels, provide a physical
line for each channel.
Peer-to-peer communication
(between the S10mini or S10V and MELSEC)
Sequencer or motion controller in which the MELSEC
A Series Ethernet® interface unit (Model AJ71E71 or
equivalent) is mounted
Fixed at 34100 (decimal notation; for both the S10mini
or S10V and MELSEC)
Any address is usable. However, the S10mini or S10V
and MELSEC must agree with each other in network
address.
