MELSEC Peer-to-Peer Network, 1:n Network, Parallel Link
The networks in details:
Peer-to-Peer
You can integrate up to 8 programmable
logic controllers in a peer-to-peer network.
All stations in the network can monitor all
the devices in the entire data range. How-
ever, data writing and setting and resetting
of individual devices is always only per-
formed in the specific station in question.
Each network station can transfer packets of
up to 64 bits and 8 data words via the net-
work.
The maximum distance between the first
and last connected stations depends on the
type of adapters used:
FX0N-485ADP: max. 500 m (CPU vers. 2.0)
FX2N-485BD: max. 50 m
1 : n Multidrop-Netzwerk
This networkisusedfor displaying and
monitoring data from the individual sta-
tions on a connected computer.
You can connect up to 16 stations in one of
these networks. The maximum distance be-
tween the first and last connected station
depends on the type of adapters used:
FX0N-485ADP: max. 500 m
FX2N-485BD: max. 50 m
Parallel Link
As the name indicates, parallel link mode
connects two programmable logic control-
lers with a parallel link. Data communica-
tion between the two states is performed
automatically via a predefined range of
relays and data registers.
The maximum distance between two sta-
tions connected by parallel link is 50 m.
If the FX0N-485 ADP is used, the maximum
distance will be 500 m.
