Parameters
(c) Input need not be pulsed by use of differential contact
An input need not be pulsed by use of a differential contact( / ).
(d) Direct access to intelligent function module buffer memory
The intelligent function module buffer memory can be handled as devices for
programming. ( Section 9.5)
(e) Direct access to link devices
The link devices (LX, LY, LB, LW, SB, SW) of the MELSECNET/H network module can
be accessed directly without refresh setting.
