Data link device range
The following describes the data link device range for each operation mode.
The data link range for inputs (X) and outputs (Y) is determined by the data link
module used as the master station. The maximum value is indicated below. For
example, if an A2NCPU or A2ACPU is used as the master station, the X/Y range that
can be used for data link is 0 to 1FF (512 points).
(a) MELSECNET mode
X/Y : 0 to 7FF (2048 points)
B : 0 to 3FF (1024 points)
W : 0 to 3FF (1024 points)
The data link range for link relays (B) and link registers (W) is B/W0 to 3FF (1024
points) when a MELSECNET
local station.
(b) MELSECNET mode
X/Y : 0 to 7FF (2048 points)
B : 0 to FFF (4096 points)
W : 0 to FFF (4096 points)
(c) MELSECNET composite mode
X/Y : 0 to 7FF (2048 points)
B : 0 to FFF (4096 points)
W : 0 to FFF (4096 points)
The data link range for link relays (B) and link registers (W) that can be data
linked by the MELSECNET-compatible local station is B/W0 to 3FF (1024
points).
