 Stand-alone 32 point I/O System (Type A1/Type A2)
The LT can independently control up to 32 external I/O units (DC 24V 16-point
Input/16-point Output).
I/O Units
Connecting Flex Network units to the LT unit allows you to use the LT to control
remote I/O.
Flex Network I/O units are connected to the LT via the Flex Network I/F unit,
which is equipped with 2 channels — CH1 and CH2. Through these channels, the
LT can send identical communication data. You can select either one of these
channels, or both, when sending communication data to the external I/O units.
Using a single channel enables you to send communication data to 31 I/O units via
one channel, and to 32 I/O units via the other channel. Therefore, using both
channels, the LT can communicate with a total of 63 Flex Network I/O units.
