(Note 1) (Note 5)
(Note 1): The remote programming function and data transfer function (transfer by SEND/RECV instructions) are
available for PLCs in the same hierarchy (depth 0). They cannot be executed for PLCs in the different hierarchy
(depth 1).
(Note 2): Slot numbers are set in the range of 01h to 10h (1 to 16).
(Note 3): The relay position for the FP7 CPU is specified with a slot number. The depth is selected from 0 or 1.
(Note 4): For communicating with MEWTOCOL7, the system must consist of MEWNET-W2 and FP7 only.
(Note 5): Data must be sent by the minimum size limited in the transmission path.

Specifications
Available only when the units in W mode are two. When
there are more than three units, it cannot be used as the
relay station.
Not available
Not available
There is no restrictions when the installed units are up to
4 units (i.e. max. connectable number of units).
Not available
Communication cannot be performed when another
command for the same function (computer link, data
transfer, remote programming) is sent to the same relay
station
