below the number of inputs/outputs
specified in the operation mode of
the Base. Change the operation
mode of the Base or the number of
inputs/outputs mapped to the
wireless system (Base and
Remotes).
(3) This is a CC-Link station number
setting error (factory preset).
Specify the correct station number.
(4) The number of registered Remotes
has exceeded the set value.
Change the operation mode of the
Base. Delete the registrations of the
Remotes (wireless channels) outside
of the set range or change the
wireless channels to valid channels.

operations are not performed
normally.
Initialize the product.
