Data Link System
One
OpenNet Controller
at the master station can communicate with 31 slave stations through the RS485 line to exchange
data and perform distributed control effectively. The RS485 terminals are connected with each other using a 2-core twisted
pair cable.
For details about the data link communication, see page 21-1.
Basic System
The
OpenNet Controller
CPU module can be mounted with seven modules including digital I/O and functional modules
such as analog I/O, DeviceNet slave, and L
ON
W
ORKS
interface modules to set up a stand alone system. When using seven
digital I/O modules, the I/O points can be 224 points at the maximum.
Expansion System
The FC3A-EA1 expansion power supply module is used to mount more than seven I/O and functional modules. When a
maximum of 15 I/O modules are mounted, the number of I/O points is expanded from 224 to 480 maximum.
Whether an expansion power supply module is used or not, seven functional modules such as analog I/O, DeviceNet slave,
and L
ON
W
ORKS
interface modules can be mounted at the maximum in either the normal or expansion slots.
