LINK PARA. ERROR
Since the number of points of the B/W device set
in [Device] of the PLC parameter is lower than
the number of B/W refresh device points when
parameters of the MELSECNET/H are not set, the
refresh between the CPU module and the MELS-
ECNET/H cannot be performed.
Number of B/W refresh device points when para-
meters of the MELSECNET/H are not set:
– 1 network module mounted
B: 8192; W: 8192
– 2 network modules mounted
B: 8192 (4096x2); W: 8192 (4096x2)
– 3 network modules mounted
B: 6144 (2048x3); W: 6144 (2048x3)
– 4 network modules mounted
B: 8192 (2048x4); W: 8192 (2048x4)
