1-1 Features
The CPU handles the Interface Units as I/O Units, thereby eliminating tedious
procedures. Using a G730 Interface Unit allows signals for remote I/O equip-
ment, such as switches and lamps, to be handled and controlled by the G730
Remote Terminal.
The G730 Remote Terminal is a terminal block with added communications
functions. It is connected to remote I/O equipment and PCs. Connection to
the PC by a single pair of cables reduces wiring effort.
For more information about the G730 Remote Terminal, refer to the I/O Termi-
nal Series Catalog (X044).
CQM1-G7M21 Master Switch settings on the Master allow simultaneous connection of G730
Remote Terminals (Slaves) with up to 32 input points and 32 output points.
Up to two Expansion Masters can be connected to each Master (one system)
to permit control of up to 128 points.
Multiple Masters can be used.
Connection of multiple Masters in separate systems permits control within the
range permitted for the CPU.
The number of input points and output points can independently be switched
between 32 and 16.
The HOLD/HOLD OFF setting determines whether the signals into the CPU
are held (HOLD) or cleared (HOLD OFF) when a transmission error occurs.
CQM1-G7N@1 Expansion
Master
An Expansion Master is used if the Master alone does not allow connection of
sufficient points. The Expansion Masters are always connected in series with
the Master and up to two Expansion Masters can be connected to each Mas-
ter.
Expansion Masters are available as Input Units (G7N11) and Output Units
(G7N01). Switch settings allow connection of G730 Remote Terminals
(Slaves) with up to 32 points.
The number of input points and output points can independently be switched
between 32 and 16 for both Input Units and Output Units.
